Book excerpt: West Welch Unit is one of four large waterflood units in the Welch Field in the northwestern portion of Dawson County, TX. This field was discovered early 1940's and produces oil under a solution gas drive mechanism from the Sand Adres formation at (almost equal to)4800 ft. This field has been under waterflood for 30 yr and a significant portion has been infill drilled on 20-ac density. A 1982-86 CO2 injection project in the offsetting South Welch Unit yielded positive results. Recent installation of a CO2 pipeline near the field allowed phased development of a miscible CO2 injection project at the South Welch Unit. Reservoir quality is poorer at West Welch Unit due to relative position to sea level during deposition, and this unit is ideal for demonstrating methods for enhancing economics of IOR projects in lower quality SSC (shallow shelf carbonate) reservoirs. This Class 2 project concentrates on the efficient design of a miscible CO2 project based on detailed reservoir characterization. During the quarter, progress was made on petrophysical analysis and tomography processing. The geologic model is dependent on these, and the actual reservoir simulation cannot start until the geologic model is complete, although all the preliminary simulation work is being done.

This Class 2 project concentrates on the efficient design of a miscible CO2 project based on detailed reservoir characterization from advanced petrophysics, 3-D seismic interpretations and cross wellbore tomography interpretations. During the quarter, simulation performance forecasts were made using the base geologic model. The surface seismic and wellbore data were combined to develop an improved geologic model for the simulator. Efforts to integrate the wellbore seismic results into the reservoir characterization continue. Problems with the wellbore seismic processing were traced to the processing software which is being corrected.

Book excerpt: The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: (1) Advanced petrophysics; (2) Three dimensional (3-D) seismic; (3) Cross-well bore tomography; (4) Advanced reservoir simulation; (5) Carbon dioxide (CO2) stimulation treatments; (6) Hydraulic fracturing design and monitoring; and (7) Mobility control agents.

Book excerpt: West Welch Unit is one of four large waterflood units in the Welch Field located in the Northwestern portion of Dawson County, Texas. The Welch Field was discovered in the early 1940's and produces oil under a solution gas drive mechanism from the San Andres formation at approximately 4800 ft. The field has been under waterflood for 30 years and a significant portion has been infill drilled on 20-ac density. A 1982-86 Pilot CO2 injection project in the offsetting South Welch Unit yielded positive results. The recent installation of a CO2 pipeline near the field allowed the phased development of a miscible CO2 injection project at the South Welch Unit. The reservoir quality is poorer at the West Welch Unit due to its relative position to sea level during deposition. Because of the proximity of a CO2 source and the CO2 operating experience that would be available from the South Welch Unit, West Welch Unit is an ideal location for demonstrating methods for enhancing economics of IOR projects in lower quality SSC reservoirs. This Class 2 project concentrates on the efficient design of a miscible CO2 project based on detailed reservoir characterization from advanced petrophysics, 3-D seismic interpretations and cross wellbore tomography interpretations. During the quarter, work continued on the simulation history match using only the base geologic model generated from available wellbore data. Tomography processing methods were further refined and 3-D surface seismic data was 1115 reprocessed to increase the frequency and decrease the bin size.

This book was released on 2003 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The OXY-operated Class 2 Project at West Welch is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality Shallow Shelf Carbonate reservoirs. The research and design phase (Budget Period 1) primarily involved advanced reservoir characterization. The current demonstration phase (Budget Period 2) is the implementation of the reservoir management plan for an optimum miscible CO{sub 2} flood design based on the reservoir characterization. Although Budget Period 1 for the Project officially ended 12/31/96, reservoir characterization and simulation work continued during the Budget Period 2. During the seventh annual reporting period (8/3/00-8/2/01) covered by this report, work continued on interpretation of the interwell seismic data to create porosity and permeability profiles which were distributed into the reservoir geostatistically. The initial interwell seismic CO{sub 2} monitor survey was conducted and the acquired data processed and interpretation started. Only limited well work and facility construction were conducted in the project area. The CO{sub 2} injection initiated in October 1997 was continued, although the operator had to modify the operating plan in response to low injection rates, well performance and changes in CO{sub 2} supply. CO{sub 2} injection was focused in a smaller area to increase the reservoir processing rate. By the end of the reporting period three producers had shown sustained oil rate increases and six wells had experienced gas (CO{sub 2}) breakthrough.

First Quarter 1995 written by and published by . This book was released on 1995 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of the project is to show that the use of advanced technology can improve the economics of CO2 projects in low permeability reservoirs. The approach involves the use of tomography, 3-D seismic and detailed petrophysical descriptions to enhance reservoir characterization. Cyclic CO2 stimulations and model designed frac treatments will be used to increase and facilitate oil recovery to improve project economics. The detailed reservoir characterization will be used to create a geological model for use in simulation to arrive at an optimum operating plan to be instituted during the second budget period. Objectives to be accomplished during the third quarter include: (1) Complete petrophysical description on cores from observation wells. (2) Apply petrophysical data to geologic model. (3) Conduct additional laboratory analysis on cores and fluids. (4) Refine 3-D seismic interpretations. (5) Complete tomography surveys. (6) Process tomography data. (7) Establish relationship between seismic and tomography interpretations. (8) Conduct preliminary simulator runs with improved geologic model. (9) Evaluate results of cyclic CO2 stimulation treatments. (10) Design frac treatment for linear flood fronts. All of the above objectives were worked on during the current quarter and the overall project is fairly well on schedule. The area of greatest concern time-wise is reservoir simulation. The simulator depends on the geologic model, which in turn depends on the petrophysical, 3-D seismic and tomography interpretations. Hence, the final geologic model won't be available until all of the reservoir characterization work is completed.

Progress was made on interpreting the crosswell seismic data and the CO2 performance simulation was further improved. Construction of facilities required for CO2 injection were completed.
