Stuck pipe or sticking and lost circulation are the two main events which cause Non-productive time (NPT) in the drilling industry. A considerable amount of time and resources can be spent in efforts to free a stuck pipe. Sometimes, stuck pipe events result in breakage (either intentional or non-intentional) of the drill string leading to a lot of money being spent in fishing. Unsuccessful fishing operations have resulted in costly alternatives including side-tracking or worse still, well abandonment. Stuck pipe situations are very common around the world with most data gathered in the petroleum drilling industry.
Good solids-removal equipment operation, including that of shale shakers, helps prevent these problems.
Drilling waste can be stocked in the waste pit or collected by trucks or vacuum truck, and dumped near the site work for treatment.
Smooth operations of solids-separation equipment are accomplished with proper planning and utilization of the needed equipment to efficiently and effectively remove drilled solids from a drilling fluid. This chapter provides guidelines to ensure the smooth and efficient operations of solids-removal equipment and associated drilling-fluid equipment. This chapter is primarily directed toward rig personnel as a practical guideline for better drilling practices. Many of these suggestions and guidelines are discussed in much greater detail in other chapters of this book. This chapter consists of three sections: Solids Control Equipment Guidelines and operations of the various solids-removal equipment; Equipment Guidelines and additional thoughts and considerations for smooth operations of the various drilling-fluid handling equipment and tankage; Solids Management Checklist and questions to consider for proper sizing, selection, and operation of a solids-management system.
