CONFORMANCE CONTROL, SWEEP EFFICIENCY, DEEP DIVERSION, AND WATER SHUTOFF METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17644109 titled 'CONFORMANCE CONTROL, SWEEP EFFICIENCY, DEEP DIVERSION, AND WATER SHUTOFF METHOD
Simplified Explanation
The patent application describes a method for injecting a foam injectant and a gel injectant into a formation through an injection well.
- The foam injectant consists of a liquid phase with a surfactant, water, and a gas phase.
- The gel injectant consists of a water-soluble polymer and a crosslinker.
- The foam injectant and gel injectant are pumped into the well at separate times and sequentially.
Potential Applications:
- Enhanced oil recovery: The method can be used to improve the recovery of oil from underground formations by creating a foam and gel barrier that helps push the oil towards the production well.
- Hydraulic fracturing: The foam and gel injection can be used in hydraulic fracturing operations to improve the efficiency of the fracturing process and enhance the flow of oil or gas.
Problems Solved:
- Inefficient oil recovery: The method addresses the challenge of low oil recovery rates by utilizing a combination of foam and gel injectants to improve the displacement of oil from the formation.
- Poor fluid flow in hydraulic fracturing: The foam and gel injection helps to create a more effective fracture network and improve the flow of fluids during hydraulic fracturing operations.
Benefits:
- Increased oil recovery: The use of foam and gel injectants can enhance the displacement of oil from the formation, leading to higher oil recovery rates.
- Improved hydraulic fracturing efficiency: The foam and gel injection can help create a more efficient fracture network, allowing for better fluid flow and increased production rates.
Original Abstract Submitted
A method includes providing an injection well extending from a surface into a formation and alternatingly pumping a foam injectant and a gel injectant into the injection well, wherein the foam injectant includes a liquid phase with a surfactant and water and a gas phase and the gel injectant includes a water-soluble polymer and a crosslinker. The foam injectant and the gel injectant are injected at separate times and sequentially.
