The leader in freeing differentially stuck pipe since 1988.
Coastal Spot is a unique drilling fluid additive that combines a polyalphaolefin (PAO) synthetic hydrocarbon, special emulsifiers, activators, and initiators to free differentially stuck pipe.
Differential pressure sticking is the most common cause of stuck pipe in drilling operations. Circumstances that lead to differential sticking vary and include:
As drilling fluid is lost into the formation, the small pores of the formation face serve as filters, trapping the solids present in the mud system and causing filter cake thickening. Coastal Spot dehydrates and cracks this filter cake, penetrating the area around the pipe with the highly lubricious PAO, allowing the stuck pipe to become free.
Coastal Spot contains no aromatics or other undesirable characteristics found in traditional mineral and diesel oils. Toxicity testing under NPDES guidelines shows that Coastal Spot has no effect on the LC50 of the drilling mud system and does not cause sheening.
SUN’s REDI-SPOT allows operators to keep Coastal Spot readily available on the drilling rig until the product is needed. This ensures the operator can pump the pill downhole promptly, significantly increasing the probability of success.
