Santrol acquires self-suspending proppant technology

SUGAR LAND -- Santrol, a Fairmount Minerals company, announced today the acquisition of self-suspending proppant technology from Soane Energy of Cambridge, Mass., that will enable operators to improve hydrocarbon production by substantially increasing the surface area of propped fractures to the reservoir.

The proppant, which is suspended in the fracturing fluid, is transported farther for substantially better propped fracture length. The technology eliminates the need for certain fluid additives.

This solution is a step-change in the decades-old challenge of evenly distributing proppant throughout the full length of a created hydraulic fracture. This is achieved by enveloping traditional proppant, such as Northern White sand, in a polymer that suspends the proppant in the hydraulic fracturing fluid. Once the proppant is placed in the fracture, traditional breakers remove the polymer leaving the proppant in place.

The proppant remains suspended in the fracturing fluid throughout the entire delivery process, lessening the need for fluid viscosifiers, such as guar and its derivatives, crosslinkers, friction reducers, biocides, gel stabilizers or high pH buffers. This simplified fluid requirement increases hydraulic fracturing efficiency.
