A Colorado rig contractor used MONGOOSE Max™ high-capacity shaker and SCREEN PULSE™ fluid and cuttings separator to improve separation efficiency and maintain target pumping volumes while drilling four wells using the same 40 shaker screens.

A rig contractor in Colorado needed to maintain solids handling and fluid pumping volumes while drilling multiple sections in four wells; its existing single-deck shakers were unable to meet the demands of the operator’s ambitious drilling campaign. To support the operator’s high pumping and drilling rates, the contractor sought a high-performance replacement for its legacy separating equipment.

Using the new separating equipment, the operator successfully drilled four wells with multiple sections at an average pump rate of 800 galUS/min. By optimizing fluid recovery, the operator reduced disposal and drilling fluid costs while meeting the most stringent environmental standards.

What’s more, only 5 of the 40 DURAFLO™ composite screens showed any significant wear. SLB used the M-I SWACO SNAP-LOK™ plug screen-repair system to refurbish the screens within minutes—bringing all 40 screens back into service for the duration of the four-well drilling campaign. The durability of the shaker screens not only reduced trucking requirements, forklift moves, and equipment storage, it reduced screen consumption by approximately 64% compared with conventional screens.
