Integrated approach towards the application of horizontal wells to improve waterflooding performance. [Quarterly report], April 1--June 30, 1995

Description: The overall purpose of the proposed project is to improve secondary recovery performance of a marginal oil field through the use of a horizontal injection well. The location and direction of the well will be selected based on the detailed reservoir description using integrated approach. We expect that 2 to 5% of original oil in place will be recovered using this method. This should extend the life of the reservoir by at least 10 years. In the last three months, we are busy implementing the reservoir management plan in the field. Initially six wells were targeted for re-completion and stimulation. The original plan was to complete the wells by the end of April. Unfortunately, due to unforeseen inclement weather in Tulsa and the surrounding vicinity, the plan had to be postponed. Due to excessive rains, it was very difficult to move completion rig in the field. Finally, we started the implementation plan in May. All the six wells -- five producing and one injection wells -- were first perforated at the desired sections based on the flow simulation results. In addition, the perforations were acid stimulated. Our initial response from all the six wells has been better than anticipated. Using the existing pumps, we are unable to pump down the fluid level in any of the five wells. Our next task is to re-size the pumps so that we can fully benefit from the reservoir management implementation. The injection well can also take lot more water than it could take before. Therefore, we need to increase our ability to inject more water. We have ordered a new injection pump to increase the injection rate. The pumping station should be finished by the third week of July. After that, we will be able to inject more water in the Self Unit.

Analysis of the Hydrologic Response Associated With a Shutdown and Restart of the 200-ZP-1 Pump and Treat System

Description: A number of programs have been implemented on the Hanford Site that utilize the pumping and treatment of contaminated groundwater as part of their remediation strategy. Often the treated water is reinjected into the aquifer at injection well sites. The implementation of remedial pump and treat systems, however, results in hydraulic pressure responses, both areally and vertically (i.e., with depth) within the pumped aquifer. The area within the aquifer affected by the pump and treat system (i.e., radius of influence) is commonly estimated based on detecting associated water-level responses within surrounding monitor wells. Natural external stresses, such as barometric pressure fluctuations, however, can have a discernible impact on well water-level measurements. These temporal barometric effects may significantly mask water-level responses within more distant wells that are only slightly affected (< 0.10 m) by the test system. External stress effects, therefore, can lead to erroneous indications of the radius of influence of the imposed pump and treat system remediation activities and can greatly diminish the ability to analyze the associated well responses for hydraulic property characterization. When these extraneous influences are significant, adjustments or removal of the barometric effects from the test-response record may be required for quantitative hydrologic assessment. This report examines possible hydrologic effects of pump and treat remediation actions and provides a detailed analysis of water-level measurements for selected 200-ZP-1 pump and treat system monitor wells during the recent Y2K shutdown (December 1999) and restart activity (January 2000). The general findings presented in this report have universal application for unconfined and confined aquifer systems.

Application of an Area-of-Review (AOR) Concept to the East Texas Field and Other Selected Texas Oilfields

Description: The Underground Injection Control Regulations promulgated in 1980, under the Safe Drinking Water Act of 1974, require Area-of-Review (AOR) studies be conducted as part of the permitting process for newly drilled or converted Class II injection wells. Existing Class II injection wells operating at the time regulations became effective were excluded from the AOR requirement. The AOR is the area surrounding an injection well or wells defined by either the radial distance within which pressure in the injection zone may cause migration of the injection and/or formation fluid into an underground source of drinking water (USDW) or defined by a fixed radius of not less than one-fourth mile. In the method where injection pressure is used to define the AOR radial distance, the AOR is also known as the ''zone of endangering influence.''

Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance

Description: This final report describes the progress during the six year of the project on ''Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance.'' This report is funded under the Department of Energy's (DOE's) Class I program which is targeted towards improving the reservoir performance of mature oil fields located in fluvially-dominated deltaic deposits. The project involves using an integrated approach to characterize the reservoir followed by drilling of horizontal injection wells to improve production performance. The project was divided into two budget periods. In the first budget period, many modern technologies were used to develop a detailed reservoir management plan; whereas, in the second budget period, conventional data was used to develop a reservoir management plan. The idea was to determine the cost effectiveness of various technologies in improving the performance of mature oil fields.

Increasing Waterflood Reserves in the Wilmington Oil Field through Improved Reservoir Characterization and Reservoir Management

Description: This project used advanced reservoir characterization tools, including the pulsed acoustic cased-hole logging tool, geologic three-dimensional (3-D) modeling software, and commercially available reservoir management software to identify sands with remaining high oil saturation following waterflood. Production from the identified high oil saturated sands was stimulated by recompleting existing production and injection wells in these sands using conventional means as well as a short radius redrill candidate.

Doublets and Other Allied Well Patterns

Description: This report looks at a host of balanced patterns at unity mobility ratio. The geometries and rates ranged broadly. It was found that whenever total production and injection are equal, we can gain considerable insight on the flow equations and the fluid movement. The balanced patterns, where the wells are arrayed around a single injector or a single producer, we found that simple equations can define the nature of steady state flow lines and geometries of the flow paths, and their breakthrough behavior. When the rates are not equal, but still are balanced, the geometries are more complex, but still amenable to analytic solution.

Computer Simulation of Single-Well Steam Assisted Gravity Drainage (SW-SAGD), SUPRI TR-119

Description: Steam assisted gravity drainage (SAGD) is an effective method of producing heavy oil and bitumen. In a typical SAGD approach, steam is injected into a horizontal well located directly above a horizontal producer. A steam chamber grows around the injection well and helps displace heated oil toward the production well. Single-well (SW) SAGD attempts to create a similar process using only one horizontal well. This may include steam injection from the toe of the horizontal well with production at the heel. Obvious advantages of SW-SAGD include cost savings and utility in relatively thin reservoirs. However, the process is technically challenging. To improve early-time response of SW-SAGD, it is necessary to heat the near-wellbore area to reduce oil viscosity and allow gravity drainage to take place. Ideally heating should occur with minimal circulation or bypassing of stream. Since project economics are sensitive to early production response, we are interested in optimizing the start -up procedure.

Studies of injection into naturally fractured reservoirs

Description: A semi-analytical model for studies of cold water injectioninto naturally fractured reservoirs has been developed. The model can beused to design the flow rates and location of injection wells in suchsystems. The results obtained using the model show that initially thecold water will move very rapidly through the fracture system away fromthe well. Later on, conductive heat transfer from the rock matrix blockswill retard the advancement of the cold water front, and eventuallyuniform energy sweep conditions will prevail. Where uniform energy sweepconditions are reached the cold waer movement away from the injectionwell will be identical to that in a porous medium; consequently maximumenergy recovery from the rock matrix will be attained. The time ofuniform energy sweep and the radial distance from the injection wellwhere it occurs are greatly dependent upon the fracture spacing, butindependent of the fracture aperture.

Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance

Description: Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance scanner logs through a newly drilled well. By combining the state-of-the-art data with conventional core and log data, we developed a detailed reservoir description based on an integrated approach. After conducting extensive reservoir simulation studies, we evaluated alternate reservoir management strategies to improve the reservoir performance including drilling of a horizontal injection well. We observed that selective completion of many wells followed by an increase in the injection rate was the most feasible option to improve the performance of the Self Unit. This management plan is currently being implemented and the performance is being Stage II of the project will involve selection of part of the same reservoir (Berryhill Unit - Tract 7), development of reservoir description using only conventional data, simulation of flow performance using developed reservoir description, selection of an appropriate reservoir management plan, and implementation of the plan followed by monitoring of reservoir performance. During the summer of 1995, we started implementing the reservoir management plan in the Self Unit. Last quarter, after evaluating each individual well, we decided to install electrical submersible pumps to produce three wells. The other three wells required the use of rod pumps. Production from the field improved significantly once the pumps were installed. Over the last two years, an average daily production has been approximately 40 to 45 bbls/day. Compared to a base line production of 13 bbls/day before the implementation, this is more than a 200% increase in production. determined. We are finalizing the AFE for the overall implementation. This overall implementation will include converting well no 61 into an injector, re-perforating wells M-3A and M-4A, and drilling a deviated production well between 61 and M-3A/M-4A i n east west direction. The total length is expected to be ...
