Aspects of the present disclosure relate to exploration, evaluation, development, and production of a reservoir, and more particularly to systems and methods for dynamic modeling of the reservoir through a graph representation.
A reservoir is subsurface pool of a natural resource, such as oil and/or gas, contained within rock formations, which have varying levels of porosity and permeability. The porosity is dictated by the pore volume of the rock, while the permeability relates to the ability of the rock to allow the natural resource to flow through for collection. Reservoirs are identified using hydrocarbon exploration techniques, such as seismic data acquisition, and involve drilling exploratory wells with well log measurements along the well trajectories. Well logs are a concise, indirect, and detailed plot of formation parameters versus depth that are captured using logging tools ran along the well trajectory. Using the well logs, petrophycisits may identify lithologies, differentiate between porous and nonporous rock, and identify payzones in the subsurface rock formations where the natural resource exists in exploitable quantities.
However, while characteristics of the petrophysical phenomena, including porosity and permeability, along the well trajectory may be known, uncertainty of the petrophysics of the subformation increases as distance from the well increases. Accordingly, reservoir modeling is utilized to estimate the volumetric properties of the rock for use in decision making regarding field development, future production prediction, well placement, and other reservoir development activities. Conventionally, a suite of professionals are involved in gathering the data, generating the model, simulating it through time and employing the model in decision making. Each of these professionals is typically utilizing a discrete tool that outputs results dictated by underlying assumptions by the professional and handing off the results to another professional to be used in the next step. As such, the end to end process is conventionally plagued with human error and bias in the results generated by each tool with no retention of the disparate professional opinions that were presented during the discrete processes but rejected. In addition to human error and bias influencing the results, conventional systems and methods have inconsistent workflows and inefficient handoffs and fail to integrate the discrete tools with disparate programming languages and to retain alternative opinions, assumptions, and underlying data. Overall, conventional systems and methods fail to meaningfully reduce uncertainty and risk in reservoir exploration, evaluation, development, and production. It is with these observations in mind, among others, that various aspects of the present disclosure were conceived and developed.
Implementations described and claimed herein address the foregoing problems by providing systems and methods for developing a reservoir. In one implementation, a static model of the reservoir is received. The static model has one or more clusters of rock types. A reservoir graph is generated from the static model. The reservoir graph represents each of the one or more clusters as a vertex. A graph connectivity of the reservoir graph is defined through a nodal connectivity of neighboring vertices. Pressure values are propagated across three-dimensional space of the reservoir graph using the connectivity. A dynamic model of the reservoir is generated using the pressure values and fluid saturation values.
Other implementations are also described and recited herein. Further, while multiple implementations are disclosed, still other implementations of the presently disclosed technology will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative implementations of the presently disclosed technology. As will be realized, the presently disclosed technology is capable of modifications in various aspects, all without departing from the spirit and scope of the presently disclosed technology. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not limiting.
Aspects of the present disclosure involve systems and methods for the characterization and exploitation of a reservoir using artificial intelligence techniques. Generally, a reservoir development system is an end to end automated system permitting local expertise to be injected into a series of modular processes with a handoff between the modular processes conducted through a common integration platform. The reservoir development system thus provides an integration platform for numerous data-driven, physics-based, expertise and policy elements to determine where to drill in the reservoir with a justification for which the underlying reasoning may be traced. To arrive at the decision of where to drill, the reservoir development system generates a static model comprising a probabilistic geological representation of the reservoir. The reservoir development system quantifies uncertainty in the static model and considers risk in the reasoning. From the static model, the reservoir development system generates a dynamic model of the reservoir, which analyzes the aspects of the reservoir that change over time through a graph representation. Given the dynamic model, the system uses graph traversal algorithms to find a travel-time between different nodes of the graph. The reservoir development system provides a ranking of target volumes for drilling with supporting information in relative and absolute terms detailing how the ranking was produced. If any of the underlying information changes, the reservoir development system may provide real time reranking. Overall, the reservoir development system reduces human bias and error, provides a consistent workflow, facilitates handoffs, retains alternative opinions and supporting information, addresses uncertainty, and accommodates changes to the supporting information. These benefits, among others, will be apparent from the present disclosure.
To begin a detailed description of an example reservoir development system 100, reference is made to
In one implementation, the reservoir development system 100 includes a static modeler 102, a dynamic modeler 104, and a reasoner 106. The static modeler 102 generates a static model of the reservoir using a neural network 108 while quantifying uncertainty, and the dynamic modeler 104 generates a dynamic model of the reservoir using the static model. In one implementation, a plurality of dynamic models is generated to preserve the uncertainty represented in the static data. The reservoir development system 100 determines a validation of the dynamic models. Based on the dynamic model(s), the reasoner 106 generates a ranking of target regions for drilling with supporting information in relative and absolute terms detailing how the ranking was produced. In one implementation, macro-variables, such as connected oil volume, are produced from a graph representation of the reservoir by the dynamic modeler 104, and the macro-variables are received by the reasoner 106, which ranks the macro-variables against a set of rules.
The reservoir development system 100 receives and digests data from one or more sources. In one implementation, the data includes reservoir data 110 captured using one or more measuring tools deployed at a reservoir and expert data 112 including reservoir data having one or more attributes expertly labeled by a professional. Any changes to the expert labels of the same attribute may be retained and stored in a database for subsequent access and analysis.
In one implementation, the reservoir data 110 includes, without limitation, field data and well data. The field data may include four-dimensional (4D) seismic data, which incorporates a plurality of time-lapsed three-dimensional (3D) subsurface images portraying changes in the reservoir over time. The well data includes various information captured about one or more wells at the reservoir and may include, without limitation, well name, well trajectories, well logs, completions, production, pressure, and/or the like. Each of the well trajectories is a path along which a well is drilled at the reservoir. Well logs are a concise, indirect, and detailed plot of formation parameters versus depth that are captured using logging tools ran along the well trajectory. The well logs may include gamma ray (GR), neutron porosity (NPss), bulk density (RhoB), shallow, medium, and deep resistivities (RDeep, Rmedium, Rshallow), and/or the like. The completions may include perforation intervals, and the production may include oil production, gas production, and/or water production. The pressure may include buildup test results.
The expert data 112 may include, without limitation, expertly labeled seismic data, expertly labeled well logs, OWCS, and/or the like. The expertly labeled seismic data may include fault data and/or surface data, and the expertly labeled well logs may include permeability, porosity, and/or the like. The expert data 112 may include the same data labeled by a plurality of experts with commonalities and differences of attributes labeled by the experts tracked and stored.
In one implementation, the static modeler 102 receives static data of the reservoir data 110 and the expert data 112, and utilizing a chain of supervised and unsupervised machine learning algorithms, the static modeler 102 realizes a static characterization of the reservoir while quantifying uncertainty. More particularly, the static modeler 102 receives well logs and well trajectory data, including a set of observed data points (with x, y, and z coordinates for each measurement) in a volume along a well trajectory. Using the well logs and the well trajectory data, the neural network 108 of the static modeler 102 generates 3D populated logs across a volume of the reservoir.
Uncertainty increases with distance away from the well trajectory where volumetric density of information is lower. As such, the static modeler 102 quantifies uncertainty using the neural network 108. In one implementation, the static modeler 102 generates n random points in 3D space. For each of the observed data points in the well trajectory data, the static modeler 102 generates a set of feature vectors based on a distance between the observed data point and each of the random points. Each feature vector includes corresponding log values from the well logs. The neural network 108 is trained with the feature vectors and propagates the values across the volume of the reservoir to generate a 3D populated log. The source of the uncertainty is the n random points. To address this uncertainty, the static modeler 102 changes the random points, which changes the training data for the neural network 108 and thus the 3D populated log generated by the neural network 108. As such, the neural network 108 generates a plurality of 3D populated log realizations that are each different and equally probable.
In one implementation, the static modeler 102 generates log attributes, including permeability, porosity, initial water saturation, and/or the like, populated across the 3D representation for each realization. Petrophysicist assigned rock properties, including porosity and permeability, may be used to train a transformation function from log attributes to permeability, porosity, initial water saturation, and/or the like. The log attributes are generated using a k-nearest neighbors algorithm, using an average of the different 3D populated log realizations. The k-nearest neighbors algorithm is thus performed over many instances for each of NPSS, RhoB, GR, and RDEEP.
From the static log values, the static modeler 102 generates a static model of the reservoir by clustering the reservoir into one or more rock types. In one implementation, the static model is generated through k-means clustering, which partitions n observations into k clusters in which each observation belongs to the cluster with the nearest mean. The clusters of the static model obtained through the k-means clustering includes NPSS, RhoB, GR, and RDEEP values at each voxel of the 3D representation.
In one implementation, the static modeler 102 receives seismic data, which may be expertly labeled and include surfaces of one or more layers of the reservoir and fault data, including fault polygons. From the seismic data, the static modeler 102 generates fault planes through 3D plane fitting to add faults to the clusters of the static model. The static modeler is thus a static characterization of the reservoir that quantifies uncertainty.
As can be understood from
In one implementation, the dynamic modeler 104 receives clusters of rock types from the static model 200 and constructs a reservoir graph representing the clusters as graph vertices. The vertex properties of graph representation of the static model 200 includes location (x, y, z), porosity, pore volume, permeability, and initial oil saturation. Each vertex is defined to contain a spatially continuous voxel set. The dynamic model 104 defines graph connectivity 202 through nodal connectivity of neighboring clusters. The graph may be updated automatically with new fault planes, which act as nodes with zero or reduced permeability. The faults change the connectivity 202 across the domain. Low confidence faults that are identified a number of times below a threshold may be removed. The dynamic modeler 104 transforms the static model 200 into nodes including fault effects and defines the connectivity 202.
In one implementation, the dynamic modeler 104 estimates pressure 204 using the connectivity 202. The nodes with high connectivity are more likely to have similar pressures. Continuity in reservoir fluids allows for propagating pressure from observation points across the 3D network. The areas with no connectivity to the observation points are considered uncertain in pressure values. As such, when a new pressure point becomes available, the dynamic modeler 104 propagates the new pressure point across the volume. The dynamic modeler 104 utilizes the connectivity 202 in the 3D structure to propagate pressure observations 204. The dynamic modeler 104 receives 4D seismic data 206 from which the dynamic modeler 104 determines fluid saturation 208 across the reservoir. From the graph construction of the static model 200, the pressure 204, and the fluid saturation 208, the dynamic modeler 104 generates a dynamic model 210 of the reservoir. Stated differently, the dynamic modeler 104 learns over the graph construction using production and pressure data.
The dynamic model 210 may be augmented with additional data sources and updated over time, for example, as the pressure and/or the saturation changes. Further, modular properties may be ascribed to the dynamic model 210 for interpretation by the reasoner 106. The static modeler 102 and the dynamic modeler 104 reduce integration time between static and dynamic data, facilitate assimilation of pressure and saturation observations, and expedite construction of 3D plumbing of the reservoir. The reasoner 106 utilizes the reservoir model, including the static model 200 and/or the dynamic model 210, to rank sub-volumes of the reservoir as potential target regions for drilling.
In one implementation, the reasoner 106 includes a fuzzy inference engine that generates a recommendation by reasoning over the underlying reservoir model and evaluating target volumes against a set of one or more rules. The fuzzy inference engine may perform one or more stages of fuzzy inference. The reasoner 106 may generate a set of one or more features computable from the static model 200 and the dynamic model 210. For example, the set of features may include 24 features, such as a distance to aquifer, short term connected oil volume, long term accessible energy, and/or the like. The reasoner 106 utilizes the set of rules relating the values of the set of features to a drilling attractiveness of a node. For example, if energy is high and connected water volume is low and connected oil volume is high and connected oil volume uncertainty is low, then drilling attractiveness is high. Similarly, if short term accessible energy is high and medium term accessible energy is high and long term accessible energy is high, then energy is high. As another example, if distance to aquifer is high then drilling attractiveness is high.
The recommendation generated by the reasoner 106 includes ranked volumes where potential target regions for drillings are ranked in a list. For each of the rankings, the reasoner 106 provides an audit trail detailing, in relative and/or absolute terms, how the ranking was produced. The reasoner 106 further monitors the static modeler 102 and the dynamic modeler 104 for updates, including new inputs and/or changes. If the reasoner 106 detects any updates, the reasoner 106 generates a reranking of the target regions in real time.
Stated differently, in one implementation, the reasoner 106 executes a policy of the set of rules defining desirable and undesirable volume features, and the reasoner 106 combines values for different categories hierarchically to produce an aggregate score for each of the volumes. The ranked volumes includes each of the target regions ranked in a list according to the aggregate scores. As such, the ranked volumes are quantitative ratings, which are output as a user interface that a user may interact with using a user device to inspect the underlying rationale of the rankings to identify target regions for drilling.
As can be understood from
G
R=(V,E), where V={v1,v2, . . . ,vn} and E={ . . . ,(vi,vj), . . . }
V is thus the set of vertices and E is the set of edges for the graph. The vertex vi is the centroid of cluster i. For each of the realizations of the static model 300, the reservoir graph 302 may be constructed. In one implementation, the raw static cluster outputs of the static model 300 are further divided in constructing the reservoir graph 302, such that: each cluster has at most one pressure observation point; only one perforation passes through the cluster; and each cluster contains a spatially continuous voxel set only. With respect to the spatially continuous voxel set, a post-processing on the clusters may break discontinuous clusters into continuous blobs. Further, a smoothing algorithm may be applied to dissolve very small clusters in the reservoir graph 302.
Turning to
The location (xi, yi, zi) is a center of mass for a set of connected voxels in the cluster i. The porosity φi is an average porosity for voxels in the cluster i, and pore volume is PVvi: ΣviN Vnφn, where N is a number of voxels in the cluster i and Vn and φn respectively, are a volume and a porosity of voxel n in the cluster i.
The permeability K, is an average permeability of the cluster i. In one implementation, since the clusters are defined using permeability values, it is assumed the permeability is continuous in the cluster i. Stated differently, there should be no flow barrier (high permeability contrast) with the cluster itself, and permeability anisotropy is minimal. As such, directional permeability may be disregarded. In another implementation, the clusters are analyzed to ensure there is no flow barrier, however narrow, that can block an entire cross section in a given direction. Heterogeneity in permeability may be tolerated where it is dispersed in the space, and to account for this, directional permeability may be calculated for each of the clusters using a flow simulation or approximation. Similarly, the initial oil saturation Soi is an average initial saturation for voxels in the cluster i. A continuity for the initial oil saturation may be assured similar to the permeability.
In one implementation, the passing well name is the name of the well passing through the cluster i. With respect to fault, if the vertex represents a fault, the value is true. Otherwise, the value is false. In one implementation, if the vertex is a fault, its permeability is zero. In another implementation, if the vertex is a fault, the permeability may be manually or otherwise automatically specified based on the reservoir data 110 and/or the expert data 112. In yet another implementation, the permeability is specified as a learnable parameter.
In one implementation, the vertex i is defined to be a neighbor of vertex j only if their parent clusters have a common surface Sij. The area of Sij is denoted as aij and the center point is Cij with dij defined as the Euclidean distance from (xi, yi, zi) to Cij For each vertex vi, adjacent vertices, shared area with neighbors, a central point of common surfaces, and other properties using neighbor identification algorithms for edge detection of the reservoir graph 302. The adjacent vertices includes a list of neighbors with vertex i. The shared area with neighbors includes a list of the areas between the vertex i and its neighbors, and the central common point of the common surfaces includes a list of the central point of common surfaces between the vertex i and its neighbors.
Once the edges are detected, a weight is assigned to the edge (vi, vj) connecting vertices vi and vj. In one implementation, the connectivity is defined by applying Darcy's law for a series system:
The effective permeability is therefore:
and the static connectivity is:
The static weight is thus:
A time of travel is defined as a time it takes for a pressure drop in vertex i to be felt by vertex j. Using radius investigation in the context of a diffusivity equation, the travel distance or time of travel may be defined as:
The nodes i, j, thus have static connectivity Dij, pressure connectivity CPij, water connectivity CWij, and oil connectivity COij defined as follows:
As shown in a representation 402 of
P
unlabeled=(i−TUU)−1TULPobserved
In one implementation, every representation 410 for the graph results in one estimated pressure, with uncertainty represented through uncertainty in the representations 410. As described herein, there are different realizations of the static model 300, thereby resulting in different clusters shown as reservoir graphs 302, which in turn results in different pressures shown in the representations 410.
The nodes with high connectivity are more likely to have similar pressures. Continuity in reservoir fluids allows for propagating pressure from observation points across the 3D network. The areas with no connectivity to the observation points are considered uncertain in pressure values. As such, when a new pressure point becomes available, the new pressure point is propagated across the volume, as it might represent an isolated section of the reservoir. The connectivity in the 3D structure is thus used to propagate pressure observations.
Turning to
The reservoir graphs may have various nodal properties, graph traversal attributes, and/or the like. For example, the nodal properties may include, without limitation, vertex, vertex location, porosity, pre volume, permeability, vertex height, water saturation, static uncertainty, list perforations, fault, fault confidence, shale, aquifer, adjacent vertices, edge weights, time distance, boundary central voxel, shared area neighbors, pressure, and/or the like. The graph traversal attributes may include, without limitation, sorted path index, sorted path time, distance to aquifer, transmissibility, short term connected oil volume, cumulative production of short term interfering wells, short term accessible energy, short term connected water volume, short term connected oil volume uncertainty, medium term connected oil volume, cumulative productions of medium term interfering wells, medium term accessible energy, medium term connected water volume, medium term connected oil volume uncertainty, long term connected oil volume, cumulative production of long term interfering wells, long term accessible energy, long term connected water volume, long term connected oil volume uncertainty, number of nearby faults, average connectivity of nearby faults, average confidence of nearby faults, number of midway faults, average connectivity of midway faults, average confidence of midway faults, number of distant faults, average connectivity of distant faults, average confidence of distant faults, and/or the like. The reasoner 106 may utilize these attributes in generating the ranked volumes.
