Patent Application
20180052903
The present disclosure relates generally to data processing and analysis and, more specifically, to data processing and analysis tools for predictive modeling of future hydrocarbon production from wells in a field based on historical well production data.
Various modeling techniques are commonly used in the design and analysis of hydrocarbon exploration and production operations. For example, a geologist or reservoir engineer may use a geocellular model or other physics-based model of an underground formation to make decisions regarding the placement of production or injection wells in a hydrocarbon producing field or across a region encompassing multiple fields. In addition, numerical data models may be used in conjunction with different statistical methods for is estimating or predicting future hydrocarbon production from the wells once they have been drilled into the underground formation. The accuracy of the prediction may be dependent upon the model's capability to detect relevant variables associated with wellsite operations in the field or region, which have the greatest impact on production.
However, the detection of such variables is usually difficult due to the different types of variables that may be detected. For example, the types of variables impacting production from a well generally include uncontrollable variables and controllable variables. Uncontrollable variables are fixed variables that cannot be adjusted, for example, as part of a configurable option for a stimulation treatment. Controllable variables on the other hand are adjustable, e.g., for purposes of controlling production from the well going forward. However, as some controllable variables are inherent to the nature of the hydrocarbon recovery process itself, such variables may be so dominant that they obscure the effect of other controllable variables of interest.
Embodiments of the present disclosure relate to transforming well production data for improved predictive modeling. While the present disclosure is described herein with reference to illustrative embodiments for particular applications, it should be understood that embodiments are not limited thereto. Other embodiments are possible, and modifications can be made to the embodiments within the spirit and scope of the teachings herein and additional fields in which the embodiments would be of significant utility.
In the detailed description herein, references to “one embodiment,” “an embodiment,” “an example embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to implement such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. It would also be apparent to one skilled in the relevant art that the embodiments, as described herein, can be implemented in many different embodiments of software, hardware, firmware, and/or the entities illustrated in the figures. Any actual software code with the specialized control of hardware to implement embodiments is not limiting of the detailed description. Thus, the operational behavior of embodiments will be described with the understanding that modifications and variations of the embodiments are possible, given the level of detail presented herein.
As noted above, embodiments of the present disclosure relate to transforming well production data for improved predictive modeling. In one example, the disclosed embodiments may be used to transform historical well production data for use in a predictive model of future hydrocarbon production for one or more wells in a hydrocarbon producing field or wells across multiple fields in a geographic region. The predictive model may be, for example, any type of numerical model for estimating or predicting the future hydrocarbon production based on the transformed data. As will be described in further detail below, the well production data may be transformed so as to improve the detectability of different types of variables that impact production. Such variables may be related, for example, to the products or processes involved in a production operation or stimulation treatment for stimulating production through fluid injection.
As used herein, the term “controllable variables” refers to variables that may impact hydrocarbon production from a well and that are adjustable by a user, e.g., for purposes of improving production based on the analysis of production data obtained for the well. Examples of controllable variables may include, but are not limited to, adjustable properties or design options associated with a stimulation treatment.
In contrast, the term “uncontrollable variables” is used herein to refer to fixed variables that may impact production and that are not adjustable by the user. Examples of uncontrollable variables may include, but are not limited to, geographic or physical parameters associated with a well. Such parameters may include, for example and without limitation, one or more of a geographic location of each of the one or more wells, a total vertical depth of a wellbore drilled at each of the one or more wells, and a bottom hole reservoir pressure within the wellbore at each of the one or more wells.
In an embodiment, aggregated well production data, e.g., in the form of a time-series production values, may be transformed such that uncontrollable variables impacting production are incorporated. The transformed data may be grouped into clusters based on the uncontrollable variables and standardized to magnify impact of causal variables in the model. This allows for variations in production due to the different types of variables to be accounted for and the quality of the data to be improved for purposes of comparative analysis and better detection of these variables in the predictive model.
Embodiments of the present disclosure may be used, for example, as an essential preparatory mechanism for complex multivariate analysis to determine the relationship between well production and reservoir, wellbore, completion, and treatment parameters. Further, the disclosed embodiments may benefit petroleum engineering teams by providing team members with a capability to understand the impact of stimulation products and processes on production and use that understanding to drive idea generation and the development of new, customized solutions. Moreover, the data transformation techniques disclosed herein may be encapsulated within a standard data analysis and modeling application executable at a user's computing device, in which complex statistical analysis and modeling features can be implemented in the background and kept hidden from the user. For example, such an application may provide the user with access to sophisticated production data analysis functionality via a relatively straightforward/simplified user interface that does not require the user to have any formal training or particular background in statistical, modeling or data sciences. This would also save the user considerable time and effort in gathering and cross-checking multiple data sources for data mining and analysis purposes.
Other features and advantages of the disclosed embodiments will be or will become apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional features and advantages be included within the scope of the disclosed embodiments. Illustrative embodiments and related methodologies of the present disclosure are described below in reference to
In order to gather the produced hydrocarbons for sale, the hydrocarbon field has one more production flow lines (or “production lines”). In
In some cases, the secondary recovery fluid is delivered to injection wells 102A and 102B by way of trucks, and thus the secondary recovery fluid may only be pumped into the formation on a periodic basis (e.g., daily, weekly). In other cases, and as illustrated in
As shown in the example of
In some implementations, one or more of the measurement devices may be in the form of a multi-phase flow meter. A multi-phase flow meter has the ability to not only measured hydrocarbon flow from a volume standpoint, but also give an indication of the mixture of oil and gas in the flow. One or more of the measurement devices may be oil flow meters, having the ability to discern oil flow, but not necessarily natural gas flow. One or more of the measurement devices may be natural gas flow meters. One or more of the measurement devices may be water flow meters. One or more of the measurement devices may be pressure transmitters measuring the pressure at any suitable location, such as at the wellhead, or within the borehole near the perforations.
In the case of measurement devices associated with artificial lift, the measurement devices may be voltage measurement devices, electrical current measurement devices, pressure transmitters measuring gas lift pressure, frequency meter for measuring frequency of applied voltage to electric submersible motor coupled to a pump, and the like. Moreover, multiple measurement devices may be present on any one hydrocarbon producing well. For example, a well where artificial lift is provided by an electric submersible pump may have various devices for measuring hydrocarbon flow at the surface, and also various devices for measuring performance of the submersible motor and/or pump. As another example, a well where artificial lift is provided by a gas lift system may have various devices for measuring hydrocarbon flow at the surface, and also various measurement devices for measuring performance of the gas lift system.
In an embodiment, the information collected by the measurement device(s) at each wellsite may be processed and stored at a data store of each of data processing devices 114A-H. In some implementations, collected measurements from each measurement device may be provided to each of data processing devices 114A-H as a stream of data, which may be indexed as a function of time and/or depth before being stored at the data store of the respective data processing devices 114A-H. The indexed data may include, for example, collected measurements of well stimulation treatment parameters, such as types of materials used during different stages of stimulation, quantities of materials applied during the stimulation, rates at which materials were applied during the stimulation, pressures of application, and various cycles of stimulation treatments applied to a well. In another example, indexed data may include measured drilling parameters, such as drilling fluid pressure at the surface, flow rate of drilling fluid, and rotational speed of the drill string in revolutions per minute (RPM). The indexed data may be stored in any of various data formats. For example, measurement-while-drilling (MWD) or logging-while-drilling (LWD) data may be stored in an extensible markup language (XML) format, e.g., in the form of wellsite information transfer standard markup language (WITSML) documents organized and/or indexed against time/depth. Other types of data related to the stimulation, drilling or production operations at each wellsite may be stored in a non-time-indexed format, such as in a format associated with a particular relational database. In other cases, historical production data for each of production wells 100A-H may be stored in a binary format from which pertinent information may be extracted for data mining and analysis purposes.
In some implementations, system 200 may be a server system located at a data center associated with the hydrocarbon producing field or region. The data center may be, for example, physically located on or near the field. Alternatively, the data center may be at a remote location that is some distance, e.g., many hundreds or thousands of miles, away from the hydrocarbon producing field or region. As shown in
In an embodiment, system 200 may use network 208 to communicate with SCADA system 206 or wellsite data processing units 114A-H or a combination thereof to obtain well production data for predicting future hydrocarbon production for one or more of production wells 100A-H of the hydrocarbon producing field of
In an embodiment, the well production data obtained by system 200 (either from SCADA 206 or directly from wellsite data processing devices 114A-H) may be stored in database 210 for later access and retrieval. Database 210 may be any type of data storage device, e.g., in the form of a recording medium coupled to an integrated circuit that controls access to the recording medium. The recording medium can be, for example and without limitation, a semiconductor memory, a hard disk, or similar type of memory or storage device. The production data stored within database 210 may include, for example, historical production data that has been aggregated over a period of time for one or more of production wells 100A-H. The aggregated production data may be in the form of time-series data including, for example, a series of production values for one or more of production wells 100A-H at predetermined production increments during the period of time (e.g., hourly, daily, monthly, or at evenly spaced 30-day, 60-day or 90-day production time increments).
In an embodiment, relevant well production data may be retrieved from database 210 and provided as input to data transformation unit 202. Data transformation unit 202 may use a multi-stage process to transform the time-series well production data into transactional model data for use by predictive modeling unit 204. In an embodiment, the transformation process used by data transformation unit 202 may involve transforming well production data based on a set of uncontrollable variables identified for one or more of production wells 100A-H. An example of such a transformation process will be described in further detail below with respect to
In an embodiment, predictive modeling unit 204 may use the model data produced by data transformation unit 202 to estimate or predict future hydrocarbon production of one or more of production wells 100A-H. For example, predictive modeling unit 204 may apply the data to any of various numerical models for predicting future hydrocarbon production from a specific production well of interest or from the hydrocarbon producing field or region overall, including all of the production wells within the field or region. Such a predictive model may be updated periodically based on, for example, new production data obtained from the production well(s) in the hydrocarbon producing field or region. In some implementations, new production data from the field or region may be transformed by data transformation unit 202 and applied to the model in real-time in order to produce updated predictions of future hydrocarbon production as the well production data changes over time. The results of the predictive modeling may be presented to the user of computer system 200 via, for example, a display device (not shown) coupled to system 200.
The output of pre-processing stage 310 may include a plurality of clusters 315 of production data 302. Pre-processing stage 310 and the clustering of production data 302 will be described in further detail below with respect to
Also, as described above, the uncontrollable variables may be identified for the one or more wells based on user input 304. For example, a list of known variables associated with the well(s) or related portion of the hydrocarbon producing field or region may be presented to the user, e.g., via the above-described display device coupled to system 200. The known variables for the well(s) may be included, for example, as part of production data 302 or other context data associated with the well(s) in this example. The user may specify the uncontrollable variables by selecting them directly from the displayed list, e.g., via a mouse or other user input device coupled to system 200. Accordingly, it may be assumed that the remaining variables in the list that were not selected by the user in this example are controllable variables associated with the well(s).
The uncontrollable variables that are identified in step 410 may then be used in step 420 for normalizing the well production data 302. In an embodiment, the normalization in step 420 may be based on correlations between one or more of the uncontrollable variables and production, as will be described in further detail below with respect to

After the clusters are validated, they may be finalized in step 450. In an embodiment, the clusters may be finalized based on a mean and a standard deviation calculated for the production data within each cluster. Referring back to data transformation process 300 of
Once outliers are removed, process 700 proceeds to step 720, which includes calculating clustering parameters for each of clusters 315. In an embodiment, the calculated clustering parameters include a measure of central tendency (e.g., a mean or average) and a measure of dispersion (e.g., standard deviation) of the refined production data within each cluster. The calculated clustering parameters may help to characterize the clusters for standardization purposes. The calculated clustering parameters are then used in step 730 to standardize the response. Step 730 may include, for example, standardizing the response by centering and/or scaling the refined production data within each cluster based on the corresponding clustering parameters. Such standardization may help, for example, to make the different clusters more comparable, e.g., for visualization purposes.
Process 700 then proceeds to step 740, which includes generating transactional model data based on the standardized response produced in step 730. In an embodiment, the transactional data may be generated by transforming the scaled production data from step 730 into transactional data for inclusion in a predictive model. The transformed data may be in the form of a time series of production data. As described above, the predictive model may use the transformed time series production data to estimate future hydrocarbon production from the one or more wells within the hydrocarbon producing field or region of interest.
The above-described data transformation techniques allow well production data to be transformed such that uncontrollable variables impacting production are incorporated into the transactional data to be used for predictive modeling. Thus, advantages of the disclosed techniques include, but are not limited to, improving comparative analysis of production between different wells by grouping data into like statistical character and accounting for variations in production data due to uncontrollable variables, improving data quality by removing irrelevant outliers, and improving the detectability of causal variables in the predictive model by magnifying their impact on production through data standardization. Accordingly, the resulting predictive model may be more capable of accurately detecting and accounting for impact of controllable variables.
Bus 808 collectively represents all system, peripheral, and chipset buses that communicatively connect the numerous internal devices of system 800. For instance, bus 808 communicatively connects processing unit(s) 812 with ROM 810, system memory 804, and permanent storage device 802.
From these various memory units, processing unit(s) 812 retrieves instructions to execute and data to process in order to execute the processes of the subject disclosure. The processing unit(s) can be a single processor or a multi-core processor in different implementations.
ROM 810 stores static data and instructions that are needed by processing unit(s) 812 and other modules of system 800. Permanent storage device 802, on the other hand, is a read-and-write memory device. This device is a non-volatile memory unit that stores instructions and data even when system 800 is off. Some implementations of the subject disclosure use a mass-storage device (such as a magnetic or optical disk and its corresponding disk drive) as permanent storage device 802.
Other implementations use a removable storage device (such as a floppy disk, flash drive, and its corresponding disk drive) as permanent storage device 802. Like permanent storage device 802, system memory 804 is a read-and-write memory device. However, unlike storage device 802, system memory 804 is a volatile read-and-write memory, such as random access memory. System memory 804 stores some of the instructions and data that the processor needs at runtime. In some implementations, the processes of the subject disclosure are stored in system memory 804, permanent storage device 802, and/or ROM 810. For example, the various memory units include instructions for computer aided pipe string design based on existing string designs in accordance with some implementations. From these various memory units, processing unit(s) 812 retrieves instructions to execute and data to process in order to execute the processes of some implementations.
Bus 808 also connects to input and output device interfaces 814 and 806. Input device interface 814 enables the user to communicate information and select commands to the system 800. Input devices used with input device interface 814 include, for example, alphanumeric, QWERTY, or T9 keyboards, microphones, and pointing devices (also called “cursor control devices”). Output device interfaces 806 enables, for example, the display of images generated by the system 800. Output devices used with output device interface 806 include, for example, printers and display devices, such as cathode ray tubes (CRT) or liquid crystal displays (LCD). Some implementations include devices such as a touchscreen that functions as both input and output devices. It should be appreciated that embodiments of the present disclosure may be implemented using a computer including any of various types of input and output devices for enabling interaction with a user. Such interaction may include feedback to or from the user in different forms of sensory feedback including, but not limited to, visual feedback, auditory feedback, or tactile feedback. Further, input from the user can be received in any form including, but not limited to, acoustic, speech, or tactile input. Additionally, interaction with the user may include transmitting and receiving different types of information, e.g., in the form of documents, to and from the user via the above-described interfaces.

Some implementations include electronic components, such as microprocessors, storage and memory that store computer program instructions in a machine-readable or computer-readable medium (alternatively referred to as computer-readable storage media, machine-readable media, or machine-readable storage media). Some examples of such computer-readable media include RAM, ROM, read-only compact discs (CD-ROM), recordable compact discs (CD-R), rewritable compact discs (CD-RW), read-only digital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), a variety of recordable/rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.), flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.), magnetic and/or solid state hard drives, read-only and recordable Blu-Ray® discs, ultra density optical discs, any other optical or magnetic media, and floppy disks. The computer-readable media can store a computer program that is executable by at least one processing unit and includes sets of instructions for performing various operations. Examples of computer programs or computer code include machine code, such as is produced by a compiler, and files including higher-level code that are executed by a computer, an electronic component, or a microprocessor using an interpreter.
While the above discussion primarily refers to microprocessor or multi-core processors that execute software, some implementations are performed by one or more integrated circuits, such as application specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs).
