Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. [Quarterly] Report, March 13, 1995--June 12, 1995


Book Description

The primary objective of this project is to conduct a cost-shared geologically targeted infill drilling filed demonstration that will enhance the domestic producibility of shallow shelf carbonate reservoirs by demonstration and technology transfer of the advanced recovery technologies employed, application of integrated reservoir management and reservoir characterization. Progress reports are presented for this past quarter for the following tasks: management and administration; reservoir characterization and analysis; integrated reservoir management; and technology transfer.







Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. Quarterly Progress Report, June 13, 1995--September 12, 1995


Book Description

At this stage of the reservoir characterization research, the main emphasis is on the geostatistics and reservoir simulation. Progress is reported on geological analysis, reservoir simulation, and reservoir management.







Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. Annual Report, June 13, 1994--June 12, 1995


Book Description

This project has used a multi-disciplinary approach employing geology, geophysics, and engineering to conduct advanced reservoir characterization and management activities to design and implement an optimized infill drilling program at the North Robertson (Clearfork) Unit in Gaines County, Texas. The activities during the first Budget Period have consisted of developing an integrated reservoir description from geological, engineering, and geostatistical studies, and using this description for reservoir flow simulation. Specific reservoir management activities are being identified and tested. The geologically targeted infill drilling program will be implemented using the results of this work. A significant contribution of this project is to demonstrate the use of cost-effective reservoir characterization and management tools that will be helpful to both independent and major operators for the optimal development of heterogeneous, low permeability shallow-shelf carbonate (SSC) reservoirs. The techniques that are outlined for the formulation of an integrated reservoir description apply to all oil and gas reservoirs, but are specifically tailored for use in the heterogeneous, low permeability carbonate reservoirs of West Texas.




Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. Quarterly Technical Progress Report, December 13, 1995--March 12, 1996


Book Description

This project has used a multi-disciplinary approach employing geology, geophysics, and engineering to conduct advanced reservoir characterization and management activities to design and implement an optimized infill drilling program at the North Robertson Unit. The activities during the first Budget Period, which is now complete, consisted of developing an integrated reservoir description from geological, engineering, and geostatistical studies, and using this description for reservoir flow simulation. Specific reservoir management activities have been identified and tested. The geologically targeted infill drilling program to be implemented during Budget Period II is a result of this work.




Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. Quarterly Technical Progress Report, September 13, 1995--December 12, 1995


Book Description

The main emphasis this quarter was on the geostatistics and reservoir simulation. Assimilation of data with the geostatistics was conducted to determine the specific well locations for the demonstration program. Reservoir characterization and performance information is also included.

Book Description

Results are presented concerning reservoir performance analysis and effectiveness of hydraulic fracture treatments. A geostatistical analysis task, reservoir simulation, and integrated reservoir description tasks are also described.




Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. Quarterly Technical Progress Report, March 13, 1996--June 12, 1996


Book Description

At this stage, the main emphasis is on the Field Demonstration phase of the project. The drilling portion of the Field Demonstration has been divided into two separate phases. We are currently proceeding with the drilling and completion of the first eleven Phase I wells. Locations for the additional seven Phase III wells were chosen at a Technical Committee meeting during the first week of June. Preliminary results have been very encouraging as all the wells are producing at or above their forecasted rates. Phase I includes the drilling of four producers and one injection well (10-acre nominal spacing) in both the Section 329 study area and the Section 326/327 study area, as well as one producing well in Section 362. Phase I will be completed during the first week of July. Phase II drilling will involve the completion of the waterflood patterns to the west of the Phase I areas in Sections 329 and 327, consisting of two producers and one injection well in each area. The final Phase II well will be located near the southwest corner of Section 324, in an area of the Unit that remains relatively undrained. Producer-injection well conversions will be performed in this area, as well as other peripheral areas of the Unit to add needed water injection.




Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drilling. Quarterly Technical Progress Report, March 13--June 12, 1997


Book Description

The eighteen 10-acre infill wells which were drilled as part of the field demonstration portion of the project are all currently in service with no operational problems. These wells consist of fourteen producing wells and four injection wells. The producing wells are currently producing a total of approximately 650 bopd, down from a peak rate of 900 bopd. Unit production is currently averaging approximately 3,000 bopd, 12,000 bwpd and 18,000 bwipd. The paper describes progress in core analysis, reservoir surveillance, well stimulation, validation of reservoir characterization (includes thin section analyses, depositional environments, and paleontologic analysis), material balance decline curve analysis, and validation of reservoir simulation (includes geostatistical and deterministic).
