Abstract: The present invention comprises a test for evaluating spontaneous hydraulic fracturing fluid imbibition and oil displacement method and apparatus utilizing a composite core with a pressurized Amott cell test.

Abstract: A drill cuttings composite core apparatus, system, and method that may utilize sieve shaker equipped with a solvent wash system to separate, clean, and size cuttings, a centrifugal mill equipped with a 12 tooth rotor and 1.0 mm ring sieve, a compactor mold that may be 1.5 inches in diameter and up to 6 inches long, dual piston compactor with independent air control valves, and a spacer on top of a bottom piston that allow compacted core to be pushed up through top of mold for easy removal with no special tools or handling.

Abstract: The present invention comprises a friction flow loop test method and apparatus that simulates well bore hydraulic conditions during fracturing utilizing large dual tanks with a primary feed tank and a secondary receiving tank wherein friction reducer hydration is controlled in an environment matching the well bore and is unaffected by recirculation mixing.

Abstract: Methods of processing a fluid recovered from an oil or gas extraction operation for reuse in a hydraulic fracturing fluid are described. The methods include providing an amount of a produced fluid composition containing iron and suspended solids and controlling at least one of the conductivity, iron content, oxidative strength, and pH of the composition, such that Fenton's reagent is formed in situ. Also described are hydraulic fracturing fluids produced using fluid recovered from an oil or gas production process and treated in accordance with the methods described herein as well as systems for preparing a hydraulic fracturing fluid having, as a fluid source, fluid recovered from an oil or gas production process that has been treated in accordance with the methods described herein.
