Description
Pulling your BOP stack, particularly in deep water, is one of the singularly most costly events in the drilling of a well if it occurs. While in most cases this course of action is correctly undertaken, occasions occur when the stack pull could have been avoided. These regrettable incidents occur for a variety of reasons, including inadequate information and/or staff training, unclear understanding of regulatory or company requirements, and non-availability of experts to assist in the decision making due to time zone differences, among others.
This presentation, based on SPE 119762, presents several case studies where planned stack pulls were circumvented or could have been, as well as a systematic protocol that can be developed prior to starting a well to define the decision making process for stack pulls for your specific program.
This presentation strives to present the material in a structured framework that encourages readers to do at least some of the preparation before starting the drilling program and to analyze the problem and potential solutions in detail before deciding on a course of action.
