Construction of the prototype was enough progressed by December 2002 for initial tests of the system to be manufactured on a research rig in Houston [4]. While circulating at 10 and2400 psi, connections were successfully made using new 5-in XH drill pipe pony joints in a moving and pressurized drilling mud environment. The appropriate drilling rigs were selected based on its drilling depth and temperature at the time of sampling. The drilling mud and make-up water samples were collected on March 8, 2016, for microbial assessment from Rig X in Field A and Rigs Y and Z in Field B. All selected gas well rigs used water based drilling mud. In each drilling rig, three The drilling mud circulating system components comprises the following equipment: Active Tank(s) Reserve Tanks Sand Traps and Process The drilling fluid then travels up the Stand Pipe and Kelly Hose to the Swivel or top drive in drilling rig (TDS), both of which suspend the drill string and allow it to rotate independently from the Kelly A schematic assembly drawing of the rig is shown in Fig.1 (Ikenyiri, 2009). Other accessories that completed the design of the drilling rig include: i) Hydraulic power unit ii) Mud pump iii) Mud hose assembly iv) Hydraulic hoses, and v) The drilling stems Check list Well control Mud system & cellar area by (AD) & (DM) Status of operation by Driller Rig floor by riller & AD D 1- Check the pressure on the BOP control unit and the remote unit on the drill floor. (A) Accumulator to be 3000psi. (B) Manifold pressure 1500psi. (C) Annular preventer 950-1000psi. 2- Check chock manifold that is lineup for (hard or soft shut in as per as policy company of mud cleaners (hydrocyclones mounted over shaker screens) which incorporated the use of linear motion in their design. In the early 1980's, FSI was one of the first companies to introduce Linear Motion Shakers, which have become the principal type of shakers in use on drilling rigs today and was tagged by rig supervisors as a "rough Recently one batch of solids control equipments are shipped to oilfield service company for their drilling rig. The equipments list including 4 units of GNZS594F-SHBF shale shaker, 1 unit of GNZJ594F-3S16N mud cleaner, 2 units of GNLW454ET-VFD decanter centrifuge.. GNLW454ET-VFD decanter centrifuge is a 18 inch bowl decanter centrifuge with 74.5 inch bowl length, the clarification cone is A typical drilling rig circulating system is shown in Figure 4-1. The mud pumps draw fluid from the suction pit and pump it through the discharge manifolds, standpipe and kelly hose, and down the drillstring. At the bottom of the hole the fluid passes through the bit nozzles before returning up the annul us and through the flowline and shale BW1200 7 reciprocating drilling rig mud pump system BW1200/7 Slurry Pump is horizontal double cylinder reciprocating double action piston pump. BW1200/7 slurry pumps with simple structure, easy operation, great displacement, less wearing parts and long service life. BW1200/7 can realize to change discharge volume and pressure by using different View Rotary drilling rig.pdf from ENGINEERIN dsfefeasf at Curtin University Sarawak.
