InnoFrac Lightweight Proppant (LWP) fracture stimulation treatments use lightweight p...Download
Due to the low specific gravity of these proppants, they are neutrally buoyant and can be transported far into the formation fractures, without the settling and banking associated with conventional proppants. When pumped as a partial monolayer, or in combination with conventional proppants, larger areas of the created fractures remain propped open, improving overall fracture conductivity and increasing production.
The neutrally buoyant characteristics of the InnoFrac LWP make it well suited for fracture stimulation operations using slickwater or linear gels, where the proppant transport capacity of the fluid is diminished by low viscosity.
For extremely water sensitive formations, such as those encountered in some coalbed methane formations, InnoFrac LWP treatments have been designed and pumped with gaseous nitrogen and lightweight proppant slurries where the resulting fracture treatment contains less than 10% liquid.
The purpose of stimulating most shale formations is to create an efficient fracture network and enable proppant to penetrate more of the reservoir. Operators can face numerous obstacles that can make economic recovery challenging.
