Conducting Oil and Gas Production Data Analysis in Unconventional Reservoirs

Temporal stimulated reservoir volumes analysis in CoViz 4D.

Temporal SRV analysis in CoViz 4D is an effective way to analyze and understand critical well and formation parameters in unconventional reservoirs.

When conducting oil and gas data production analysis, engineers typically examine differing production volumes from various frac stages in a well. And while examining unstimulated and stimulated reservoir volumes (SRV) is integral, the geologic, petrophysical, geophysical, and engineering data should also be analyzed to form a complete characterization of a reservoir.

In order to form this more comprehensive characterization, engineers need the ability to assemble the varying data types within a single visual platform. This article will discuss how engineers can benefit from data integration to characterize well performance and estimate stimulation effectiveness in unconventional reservoirs.

The Challenge of Multidisciplinary Data

Oftentimes, multidisciplinary reservoir datasets—such as geologic, petrophysical, geophysical, and engineering data—are generated by software packages that frequently aren’t always compatible with one another. This presents a challenge as trying to analyze data in differing formats could lead to a loss of valuable information that should have factored into the decision-making process. Additionally, analyzing the data separately fails to render a comprehensive depiction of the reservoir—likely complicating matters as team members attempt to understand the reservoir profile.
CoViz 4D makes it easy for members of the asset team to share discipline-specific data via a data registry that stores the disk location of files and organizes them by data type. This integrated software solution automatically handles the import into the CoViz 4D Viewer, thereby allowing team members to access and analyze data without the need or knowledge of the software product that generated the data.

With a more detailed microseismic display incorporating all pertinent data via CoViz 4D, users can benefit from the ability to:

  • combine fracturing data with subsurface data in the form of reservoir simulation grids, earth models, fault geometries, or seismic data
  • visualize the depiction of hydraulic fracturing data in 3D animation
  • obtain an update on information regarding perforations, receiver locations, or well trajectories

CoViz 4D incorporates multidisciplinary data into one geospatial volume, displaying data in conjunction with other data at any position within the volume. This allows the professionals examining the data to make an overall analysis—such as an economic valuation of the reservoir—by cross-checking one set of data against the other.

Data Integration Enhances SRV Mapping

In addition to data integration and visualization, CoViz 4D also allows for SRV mapping, which gives professionals the ability to create a substantiated estimate—3D map—of the volume of the reservoir that is stimulated using microseismic data. This mapped SRV can then be used to examine variability within other types of data (geologic, petrophysical, geophysical, reservoir simulations etc) included within the mapped SRV for a particular well. The visualization of these data within the SRV can be very informative when examining varying production volumes from various frac stages in a well.

When dealing with individual well analysis, a CoViz 4D can assist users in the following ways:

  • drawing connections between wells within a single reservoir
  • the evaluation of frac efficiencies by using SRV with other data forms to modify future frac designs
Upon the completion of a stimulated volume for a single well, users can leverage CoViz 4D to match the data with other wells within a geospatial context. Best of all, the augmented analytics of current wells can translate into successful well development throughout the reservoir.

Oil and Gas Production Data Analysis with the Help of CoViz 4D

CoViz 4D has the ability to extract multidisciplinary data from external software packages and seamlessly integrate them into a comprehensive viewing environment. Assimilating this data, irrespective of discipline or format, ensures asset teams have all of the information needed to make the best decisions on the field. Also, oil and gas production data analysis is enhanced with the addition of SRV data that’s combined with subsurface data, illuminating the dynamics of a reservoir. CoViz 4D also fosters a window into frac stages, giving engineers enough leeway to make changes sooner rather than later. With enough foresight and information, professionals can achieve comprehensive reservoir analysis to maximize hydrocarbon production.
