Multi Type Application of Cement-Packer: Simple and Economic Method of Accessing By-Passed Reservoir Potential

摘要

Over a significant time-period, during the development of a field; a number of factors will contribute to an increased understanding and appreciation of the identification of pay, it’s distribution and potential. As a result, it is not unusual to find that a significant number of opportunities may exist within existing well-stock; but that these opportunities are ‘isolated’ by limitations of the original completion design. Accessing these reserves then simply becomes a question of completion ‘adaptability’, optimization and economics. Therefore this paper describes the application of a rig-less ‘cement-packer’ approach, in order to economically access these reserves, while retaining the necessary level of completion integrity. The paper describes the steps involved in achieving this, from concept, through planning to execution. Finally, a number of case-studies (with variants) are presented to demonstrate the increasing development and applicability of the process.
