Problems solved by technology
Even with conventional crushers, it is not possible to recover large amounts of polymeric material, therefore, the fracture conductivity is reduced
[0007] Currently used fracturing techniques suffer from a series of deficiencies: 1) hydraulic fracturing has the longest pressure rise time and produces a single radial fracture; 2) downhole explosives have the shortest rise time and produces compression with multiple radial fractures zone; 3) the proppant has a moderate pressure rise time and produces multiple fractures
[0008] Horizontal drilling and multistage hydraulic fracturing have produced gas from shale and tight sand formations; however, primary oil recovery is less than 20%

Provided herein is an apparatus and method for spatially directing subsurface pressure pulses to hydrocarbon-bearing formations. The apparatus includes an infusion body having a fixed shape operable to retain the exothermic reactive component prior to triggering an exothermic reaction of the exothermic reactive component, and the infusion body maintains the fixed shape during and after triggering of the exothermic reactive component. The injection body includes a chemical injection port operable to supply components of the exothermic reactive composition to the injection body. The injection body includes a reinforcing plug operable to direct a pressure pulse generated by the exothermic reactive composition in the injection body to the perforation to create a spatially oriented fracture, the spatial orientation of the spatially oriented fracture being predetermined.
Description
[0001] inventor: [0002] Ayman R. Al-Nakhli [0003] Sameeh-Batarseh technical field [0004] The present invention relates to devices and methods for spatially directing or directing chemically induced pulses. More specifically, the present invention relates to spatially directed chemically induced pressure pulses in hydrocarbon containing reservoirs. Background technique [0005] Hydraulic fracturing fluids containing proppants are widely used to enhance production from hydrocarbon-bearing reservoir formations, including carbonate and sandstone formations. During a hydraulic fracturing operation, a fracturing treatment fluid is pumped at a pressure and rate sufficient to fracture the formation of the reservoir and create fractures. A fracturing operation typically consists of three main phases: a pad phase, a proppant fluid phase, and an overflow fluid phase. The pad stage typically includes pumping the pad into the formation. A pad is a viscous gel fluid that initia...
