Method for generating an SWPM-MDT

Abstract

A Single Well Predictive Model (SWPM) software based computer system stores a Single Well Predictive Model (SWPM) software (20c1). When the SWPM (20c1) software is executed, the SWPM (20c1) will automatically produce a first specific workflow comprised of a first plurality of software modules in response to a first set of user objectives (24) and automatically execute the first specific workflow in response to a first set of input data (22) to produce a first desired product, and automatically produce a second specific workflow comprised of a second plurality of software modules in response toa second set of user objectives and automatically execute the second specific workflow in response to a second set of input data to produce a second desired product, wherein the desired product is a3D reservoir response model.

Description

technical field [0001] The subject matter of one (or more) embodiments described in this specification pertains to Single Well Predictive Model (SWPM) / Model Dynamic Tester (MDT) complex analysis workflows, specifically SWPM-MDT workflows, which will be used to Use the complete well model to simultaneously perform multi-formation tester transient analysis and well testing. Background technique [0002] Generally speaking, during the execution of software in a processor of a computer system in order to generate the final desired product, it is usually necessary to execute a first software module in the processor of the computer system to generate the first product, and then respond to the first product A second software module is individually and independently executed in the processor to produce a second product, and a third software module is then individually and independently executed in the processor in response to the second product to produce a final desired product.

[0004] Also, interval pressure transient testing (IPTT) along the wellbore using multi-probe or packer-probe formation testers is increasingly used as a means of formation evaluation. These tests typically have a duration on the order of several hours and they are along Volumes within "tens of feet" are studied both radially and vertically on the well. Multiple transient tests with overlapping influences are common in a well. Currently, multi-layer models are used that are primarily analyzed independently of each other Each of these transient tests is analyzed in detail. When their influence quantities overlap, it then becomes an iterative procedure. The whole interpretation process then takes considerable time and effort. Interval stress transient tests using numerical simulations are also performed analysis. Numerical modeling can be well suited for complex geometries (i.e., fractures intersecting packer regions) and multiphase flow but usually such numerical modeling is more complex and difficult to establish. After interval pressure transient testing, the well Can be followed by drillstem testing (DST) and / or can have extended well testing (EWT). Joint interpretation of interval pressure transient testing and conventional well testing is uncommon and creates another complication since conventional testing has Extended scope of study. The reservoir model must give increased vertical resolution near the wellbore specified by the IPTT as well as the more difficult lateral information inherent in long-term transient well tests. Use formation testers in open and It is also common to obtain pressure versus depth data in cased wellbores. In developed reservoirs, such data provide valuable information on differential depletion, regionalization, and longitudinal communication. Pressure versus depth in the analysis The binding curves for , pose a third dimension of trouble (and scale), because pressure changes along the well often reflect the depletion of various regions that incorporate broader-scale connectivity information. In this specification, a discussion on the ' An embodiment of a Single Well Predictive Model (SWPM) / Module Dynamics Tester (MDT) Workflow' (hereinafter referred to as a 'SWPM-MDT Workflow'), wherein when the workflow is fully executed by a processor of a computer, using A digital 'reservoir response model' generated by the workflow simultaneously analyzes Interval Pressure Transient Testing (IPTT), conventional well testing (e.g., drillstem testing (DST) and extended well testing (EWT)), and pressure The starting point for the depth profile. The 'SWPM-MDT Workflow' responds to a set of 'Interpretation Results' generated as reservoir rock analysis is performed along the wellbore. This is reduced to a set of A series of flow cells. These flow cells with average properties are used to provide a digital 3D model. This starting model is updated to give all transient (IPTT, DST, EWT) data and pressure versus depth curves simultaneously. When the above SWPM- The final result generated or constructed when the MDT workflow is fully executed by the computer's processor is the 'reservoir response simulator' (or 'reservoir response model' or 'single well reservoir model'), which will give With dynamic data, data at different scales will reflect and give all measures, and can be used to study optional complete Well and Production Scenarios. The analysis methods described here in the Examples in relation to the 'SWPM-MDT Workflow' described below will: Reduce the time and Effort and provide a device that combines long-term testing and pressure versus depth data.
