Mud pump used in drilling rig

Both high-pressure mud pumps are utilized on rigs to circulate the drilling fluidaround. Each type, however, has its operating limits,. . The speed of the piston is not constant during the suction and discharge strokes. During each stroke, the speed increases from zero to maximum at approximately the halfway position. . Mud pumps must be equipped with pressure relief valves. These valves prevent too high a pressure from being built up in the circulating system. The relief valves most. [pdf]

Production drill rig optimisation

By considering the entire workflow from the perspective of a production system, this paper presents a method to optimize drill rig fleet size and schedule that considers both reservoir management and operational objectives, namely maximizing production volume, meeting production targets and/or minimizing drilling and completion costs.

Drilling rig flow lines

A flow line, used on a drilling rig, is a large diameter pipe (typically a section of casing) that is connected to the bell nipple (under the drill floor) and extends to the possum belly (on the mud tanks) and acts as a return line (for the drilling fluid as it comes out of the hole), to the mud. Possum BellyThe is used to slow the flow of returning before it hits the . This enables the shale shaker to clean the cuttings out of the drilling fluid before it is returned to the pits for circulation.. . Another common add on is the sample box. This is a heavy duty rubber hose that is inserted at the end of the flow line and at the other end emplaced into the sample box itself. The sample box is used to capture sa. . A stinger line is similar to a flow line, but unlike a flow line is not used to maintain circulation. The stinger line is attached to the to allow for the pressure from a to be released.
