Shale tests show advantage of unbundling fracture fluids

According to a recent case study performed by a third-party chemical vendor, Bosque’s clay control product outperformed traditional choline chloride by almost two times in the Niobrara Shale region.

“Although the Niobrara Shale doesn’t typically have issues with clay swelling, it is moderately prone to generating fines with fracturing stress,” said Ryan Boyd, Bosque vice president of technology. “Using roller oven testing and other tests, we feel confident we’ve developed a product that tackles not only fines generation, but also overall formation stability, which potentially changes the game when trying to increase production from a well.”

Bosque specializes in unbundling fracture fluids with its OptiFluids product line. It customizes programs to ensure each chemical used in the fracking process produces the intended results based on operator goals.

“We are one of the only companies that has a single product that addresses complete reservoir management,” Boyd said. “It prevents clay hydration, mitigates fines generation and preserves the fracture network by slowing proppant embedment.”

It is well known that legacy products like potassium chloride and choline chloride inhibit the hydration of clay minerals, however the chemical mechanism that allows these products to succeed at controlling clay hydration also changes the structure of the clay mineral. These changes increase particle dislodgement from the fracture surface and soften the formation face, leading to fines generation and embedment of the proppant into the formation which can lead to closure of the fracture network and choking of the production channels.

“We can achieve increased production in the fracture network with one chemical instead of several,” he said. “Our products have the capability to address the variability of the reservoir without disruptions to fluid design or the drilling process. Significant time and cost can be saved in the lab by efficiently designing the correct testing protocol.”
