Shale Frac Design Starts with Characterizing the Shale
StrataShaleSM process recognizes shales to get the best production possible.
By understanding the physical properties of a shale play, StrataGen can design treatments that capitalize on these properties to optimize production. Fracture spacing is a critical issue in these shales. By first understanding the type of shale that you wish to complete, fracture spacing can be optimized.
Type 1 shales respond well to fluid injection. As a result, the operator can optimize stimulation by pumping more water into the reservoir and reducing the volume of proppants while achieving the same production benefits.
In type 2 shales, the ratio of free water to proppant-laden fluids is critical, requiring strong expertise in proppant design and placement. This means the operator has to spend significantly more money and time to analyze these shales as well as allocate more budget for proppant than with type 1 shales.
In type 3 shales, production optimization depends on the quality of any fracture network generated during pad injection. Typically, a high level of matrix permeability is required for these shales to respond. However, proppant placement must be considered in designing stimulation treatments because of pressure-dependent leakoff.
StrataGen provides an extraordinary level of treatment evaluation and reporting, including real-time fracture modeling, post-treatment fracture modeling and fracture performance evaluation using mini-frac data to provide our clients with results that will maximize their economic returns.
