T7 SEAL For many years Badleys has lead the industry in the field of fault seal analysis. Our Shale Gouge ratio method for assessing fault seal is the industry standard, and T7 is the benchmark for excellence in its application. From the simplicity of Triangle to the power of TrapAnalyst and the ability to assess up-dip and across fault leakage, as well as our advanced GRID capabilities, no matter which phase you are at in the E&P process there is no fault seal software as complete as T7.
