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. ... continued below

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.
