Abstract
Cementing conventional production liners is a mature topic with documented success. For wells drilled in a shallow domain, such as 4,000 feet or less, there can be challenges routinely overlooked technically as well as operationally. If not accounting for these challenges during the service delivery, it may prevent achievement of the isolation requirements. The development of the practices resulted from unfavorable cement evaluation logs that led to remedial cementing operations or worse case, premature well abandonment. A reform of the practices used to cement challenging shallow production liners included aspects of the design as well as the on-location (wellsite execution) phase of the service delivery helping to deliver the isolation requirements.
The manuscript provides guidance from a position of managing the cementing service delivery while communicating the learning's contributing to successful shallow production liner cementing in the region of the study. It may provide the same success in other areas, as the reform practices are not unique. The practices include improvements to the service delivery such as liner hanger modifications, wellsite mixing practices, cementing fluid designs and placement optimization methods.
