Mud Technology & Solids Control In Drilling & Workover

Objectives

Participants will discover how critical is the control and disposal of solids and liquids in drilling, workover and completion operation. The course starts with the source of the problem: drilling and mud. Then each mud type will explained in details: water-base and oil-based. If oil based mud is used the disposal and removal of drillcuttings will be vital. Participants will obtain answers here that address the current problems associated with these solids and disposal of oily cuttings.
