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...

Rod pump gas separation in horizontal oil wells

Horizontal wells that utilize rod pumps often use a gas separator to remove gaseous content from oil prior to pumping. These systems require complicated downhole configurations and expensive packing materials. This technology provides a simplistic alternative to gas separators that may simultaneously reduce both gas interference and oil well completion...

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...
