RECOMMENDATION ENGINE FOR A COGNITIVE RESERVOIR SYSTEM

TECHNICAL FIELD

Aspects of the present disclosure relate to exploration, evaluation, development, and production of a reservoir, and more particularly to systems and methods for identifying target regions of a reservoir having a high probability of production.

BACKGROUND

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 a volume of the natural resource and 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 that involve drilling along a well trajectory. Well logs are a concise, detailed plot of formation parameters versus depth that are captured using logging tools deployed along the well trajectory. Using the well logs, professionals 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 away from the well trajectory increases. Accordingly, reservoir modeling is utilized to estimate the petraphysics for use in decision making regarding field development, future production prediction, well placement, and other reservoir production activities. Conventionally, a suite of professionals are involved in gathering the data, generating the model, 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 use 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.

DETAILED DESCRIPTION

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 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. Using the dynamic model, 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 FIG. 1. In one implementation, the reservoir development system 100 incorporates data into an integrated model of a probable, true state of a reservoir and provides an assessment of one or more target regions of the reservoir having a high probability of production. The reservoir development system 100 expedites multi-disciplinary collaboration in an integrated platform. More particularly, the reservoir development system 100 integrates multi-physics data, diverse-expertise input and policies. Using various machine learning techniques, the reservoir development system 100 quantifies uncertainty and provides an automatic configuration and reconfiguration of plumbing of the reservoir. The reservoir development system 100 generates a model of the reservoir and reduces the model and underlying data to symptoms for one or more target regions of the reservoir. A ranking of these target regions is output by the reservoir development system 100 to a user device for interaction by a user via a user interface. An explanation of the rankings and decisions made during the process forming the basis of the rankings may be provided via the user interface. Overall, the reservoir development system 100 provides an expedited testing and analysis of hypotheses to identify target regions.

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. Based on the dynamic model, 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.

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, detailed plot of formation parameters versus depth that are captured using logging tools deployed along the well trajectory. The well logs may include gamma ray (GR), neutron porosity sandstone matrix (NPSS), bulk density (RhoB), deep resistivity (RDEEP), 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.

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 static log values, including permeability, porosity, initial water saturation, and/or the like, from the 3D populated log realizations. More particularly, the static log values 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. Petrophysicist assigned rock properties, including porosity and permeability, may further be utilized.

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 (e.g., three different layers) 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.

In one implementation, the dynamic modeler 104 receives the static model from the static modeler 102 and time dependent data for the reservoir. Generally, the dynamic modeler 104 utilizes semi-supervised artificial intelligence to build higher order connectivity relationships among static regions according to applied physics. Stated differently, the dynamic modeler 104 represents the static model as a graph and enables integration of different data-derived attributes as well as fundamental physics of flow in porous media.

In one implementation, the dynamic modeler 104 receives clusters of rock types from the static model and constructs a reservoir graph representing the clusters as graph vertices. The vertex properties of graph representation of the static model 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 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 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 into nodes including fault effects and defines the connectivity.

In one implementation, the dynamic modeler 104 estimates pressure using the connectivity. 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, as it might represent an isolated section of the reservoir. The dynamic modeler 104 utilizes the connectivity in the 3D structure to propagate pressure observations. The dynamic modeler 104 receives 4D seismic data from which the dynamic modeler 104 determines fluid saturation across the reservoir. From the graph construction of the static model, the pressure, and the fluid saturation, the dynamic modeler 104 generates a dynamic model of the reservoir.

The dynamic model 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 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. As can be understood from FIGS. 1-2, in one implementation, the reasoner 106 utilizes a reservoir model 200, including the static model and/or the dynamic model, to rank sub-volumes of the reservoir as potential target regions for drilling.

In one implementation, the reasoner 106 includes a fuzzy inference engine 202 that generates a recommendation 206 by reasoning over the underlying reservoir model 200 and evaluating target volumes against a set of one or more rules 204. The fuzzy inference engine 202 may perform one or more stages of fuzzy inference.

Generally, fuzzy logic is a many-value logic that contrary to binary logic, where truth (i.e., a consistency with a proposition) is represented strictly with a 0 or 1 (i.e., true or false), models truth as a continuum with 0 and 1 being the boundaries. Within this context, in one implementation, the reasoner 106 may generate a set of one or more input features computable from the static model and the dynamic model. 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 204 relating the values of the set of features to a drilling attractiveness of a node, which is quantified for ranking. 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.

In binary logic, being characterized as high, would necessarily equate to the value being strictly true, with low being false. Conversely, the fuzzy inference engine 202 models high as a continuum where what is meant by high could be interpreted as highest (i.e., equal to 1), higher than some (i.e., greater than 0 but less than 1), and/or the like. As such, high, low, medium, etc. as used herein as linguistic variables. A linguistic variable is a term that indexes a particular part of a value spectrum. The fuzzy inference engine 202 maps the input features into the linguistic variables according to a membership function. This mapping carries an absolute value into an interpretation for high, low, medium, etc., which is then used to evaluate a corresponding rule. In one implementation, the membership functions utilized by the fuzzy inference engine 202 are based on a trapezoidal structure where minimum and maximum values are computed in light of an absolute minimum value and an absolute maximum value for each category examined for the reservoir.

From one reservoir to the next, an absolute volume of connected oil in a node may vary considerably. The reasoner 106 thus determines how any of the nodes in a particular reservoir compare to others with respect to a value of interest. As such, the membership functions utilized by the fuzzy inference engine 202 are fit to the intervals that emerge for a particular reservoir, with high at least including a particular maximum value and low at least including a particular minimum value as computed over all nodes in the particular reservoir. For example, if there are three nodes in a system having energy values {10, 20, 50}, the membership functions are overlaid on the interval {10, 50}, allowing the reasoner 106 to achieve an interpretation of which nodes are most attractive to drill relative to the others.

In one implementation, the recommendation 206 generated by the reasoner 106 includes ranked volumes 208 where potential target regions for drillings are ranked in a list. For each of the rankings in the ranked volumes 208, the reasoner 106 provides an audit trail detailing, in relative and/or absolute terms, how the ranking was produced. In one implementation, the reasoner 106 generates the audit trail according to the nature of how the set of rules is encoded in the policy. More particularly, the policy encodes a hierarchy of if/then rules. At each step in the hierarchical inference process, the reasoner 106 caches an input value of the input feature and an evaluation of the current rule in terms of the computed membership functions. Proceeding in a forward direction, the reasoner 106 reduces all the evaluations into a single quantified result. At this point, the reasoner 106 built a tree of what was evaluated. The audit trail thus includes the tree, which is traversable in the backward direction to analyze the underlying data and logic.

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 to updated the ranked volumes 208 in real time.

Stated differently, in one implementation, the reasoner 106 executes a policy of the set of rules 204 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 ranked volumes 208. The ranked volumes 208 include each of the target regions ranked in a list according to the aggregate scores. As such, the ranked volumes 208 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.

In one implementation, a reservoir graph is generated from the static model and injected with time dependent data. 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.

Turning to FIG. 3, in one implementation, the fuzzy inference engine 202 utilizes a policy defining desirable and undesirable volume features through an input set 300 and a rule set 310, and the fuzzy inference engine 202 combines values for different categories hierarchically to produce an aggregate score 320 for each of the volumes and an output 322. The fuzzy inference engine 202 may perform one or more stages of fuzzy inference, such that the output 322 may be an intermediary value or a final value, each being quantified between 0 and 1. In one implementation, the final output is a drilling attractiveness value between 0-1, from which each of the target regions may be ranked in a list.

In one implementation, the input set 300 includes one or more inputs 302-308 for various features, each carrying a value attribute. The one or more inputs 302-308 may be computable from the reservoir model 200. The rule set 310 similarly includes one or more rules 312-318 relating the values attributes of the inputs 302-308 to a drilling attractiveness of a node for combining hierarchically to produce the aggregate score 320.
