Fairmount Santrol announced a successful six-well field trial using its proprietary Propel SSP proppant transport technology. Initial 90-day oil production increased 39 percent compared with offset wells, the company said. Field trial details are summarized in a case study available on Fairmount Santrol’s website.
In the Three Forks and Middle Bakken formations of North Dakota’s Williston basin, Enerplus Corp. compared six Propel SSP wells with five offset wells that were completed using Northern White sand in a traditional crosslinked gel fluid system. The field test comparison specified the same proppant volume per lateral foot. The production increase can be attributed to an increase in the propped surface area, the area of the hydrocarbon-rich rock that is fractured and successfully held open by proppant.
In addition to the oil production increase, Propel SSP simplified hydraulic fracturing operations by reducing fluid additive consumption by 77 percent and pumping time by 14 percent. The technology can easily be pumped at high loading rates in a low-viscosity fluid that increases hydraulic fracturing efficiency, the company said.
The operator achieved further cost efficiency because Propel SSP does not require fluid heating at temperatures at or above 35 F. This attribute differs from traditional crosslinked gel fluids that must be heated between 60 F to 70 F to hydrate. The operator achieved a savings of $0.90/bbl of water with the reduced water-heating requirement. Water-heating and chemical cost reductions accounted for more than 10 percent of the completions cost of offset wells that used a crosslinked gel.
Propel SSP proppant transport technology lowers cost-per-BOE through improved well productivity and reduced hydraulic fracturing cost based on field trials. The technology’s hydrogel polymer wrapped around a proppant rapidly swells and suspends the proppant by just adding to freshwater. With proppant uniformly distributed throughout the fracture, especially at a high loading rate of 6 lb. per gal., frac stages are completed faster with less fluid.
“We’re appreciative of the opportunity to collaborate with oilfield services companies and operators who are applying technology, such as Propel SSP,” said Brian Goldstein, product director, Propel SSP technology.
