method to generate microfractures by chemical reaction in low-carbonate-content shale reservoirs

In oil and gas production, many of the easy to access wells have already been drilled. Due to increasing energy demand, new methods that improve hydrocarbon extraction are needed. A common method to crack reservoir rocks is hydraulic fracturing, this involves pumping water, sand and chemicals into the reservoir at high pressures. In turn, this will...

Optimum Design for Gas Lift Valve Seat

This invention reports an optimization to the principle of gas lift to increase oil production using a gas lift system. Gas lift is an artificial lift that uses external sources of high-pressure gas to supplement formation gas in order to lift the well fluid. This invention reports the optimum design as reducing the amount of stem travel required to...

Fracturability Index for Optimal Well Placement and Fracture Positioning

The early detection of "sweet spots" for oil/gas well site selection and fracturing in shale reservoirs is a challenge for many operators. Most of the time, unique parameters are utilized (i.e. brittleness) to determine the "sweet spots" for well site placement. Additionally, the fractures are generally placed equidistantly. This...

Maximize liquid oil production by huff-n-puff of produced gas in shale gas condensate reservoirs

Currently, the standard practice to produce a conventional (high-permeability) gas condensate, is to inject gas and/or water to flood the gas condensate while maintaining the lower bottom-hole flowing pressure above the dew point pressure. However, keeping the flowing pressure above the dew point results in a lower pressure difference between the reservoir...

METHOD FOR ENHANCING FAR FEILD COMPLEXITY IN SUBTERRANEAN FORMATIONS

This hydraulic fracturing process, developed by Texas Tech, is a method for enhancing the far field network complexity in subterranean formations by optimizing the placement of fractures along the deviated wellbores.Texas Tech's fracking technique is a modification of the zipper frac that initiates fractures in a staggered pattern. Field tests demonstrate...
