Reducing Excessive Produced Water from Completions
Recorded On: 05/28/2020
This presentation will explore multiple topics related to excessive produced water defined as water that is not productive in moving oil to the producing well. Major themes include identifying the water source, evaluating candidates for treatment, listing available chemical and mechanical treatment solutions, calculating the economics of reducing water cut, and mentioning gaps in technology that currently exist.
Most oil and natural gas production is accompanied by water with increasing water cut through the life of the reservoir until the economic limit is reached. The water source can be from aquifer recharge, pressure maintenance via water injectors, faults or fractures from a separate water bearing zone, commingled production, or bypassing of water to the well via poor wellbore completion. Identification of the water source and determination of the problem are critical to selecting the correct solution to reduce unproductive water entering the well. Techniques for selecting candidates for treatment are reviewed and potential solutions are presented.
Specific topics will include completion types that prevent implementation of a given treatment, equipment needed for chemical treatments, design of chemical treatments, application to gas wells, and economic evaluation of success. The discussion will provide introductory information for engineers to address water issues and evaluate remediation of completions to combat excessive water.
