Sun Spot drilling fluid additive is used to free stuck drill pipe and casing and to alleviate overbalanced formation pressure, stationary drill string and excessive filter cake. Contains no aromatics or other undesirable characteristics found in traditional mineral and diesel oils and has no effect on the LC<sub>50</sub> of the drilling fluid system. Does not cause sheening.

Sun Spot® Drilling Fluid Additive

The Leader in Freeing Differentially Stuck Pipe



Sun 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. Sun 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.

Sun Spot® contains no aromatics or other undesirable characteristics found in traditional mineral and diesel oils. Toxicity testing under NPDES guidelines shows that Sun Spot® has no effect on the LC50 of the drilling mud system and does not cause sheening.

Sun’s REDI-SPOT™ Rental Program allows operators to keep Sun Spot® readily available on the drilling rig, paying a small rental on the tanks until the product is needed. This insures the operator can pump the pill down hole promptly, significantly increasing the probability for success.
