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...

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...
