Improving the Efficiency of Multistage Hydraulic Fracturing in Hard-to-Recover Reservoirs
Multistage hydraulic fracturing technology using equal-bore sleeves, providing a synergistic effect by increasing the number of stages, simultaneously reducing costs, and significantly improving process control.Approach
Application of technology that allows for multistage hydraulic fracturing without stopping pumping, with continuous cementing and full real-time control.Challenges and limitations of conventional multistage hydraulic fracturing (MSHF)
Features and advantages
The technology enables 100 or more hydraulic fracturing stages in a single horizontal well, maximizing the drainage area through an extensive fracture network.
- A uniform internal diameter of the sleeves enables high-rate hydraulic fracturing and unobstructed passage of logging and workover tools.
- The ability to close fracturing sleeves allows isolation of watered-out intervals or the execution of repeated multistage hydraulic fracturing.
- Eliminating inter-stage packers through full liner cementing significantly reduces CAPEX, simplifies well design, and enables more efficient multistage hydraulic fracturing.
- A continuous hydraulic fracturing process without interruptions optimizes operations: saves time and resources, reduces logistics costs, and lowers CO₂ emissions.
Economic effect
- Multistage hydraulic fracturing execution speed increases by 40% compared to the Plug & Perf technology.
- CAPEX for well construction is reduced by 15% due to full cementing and shorter operation times.
- The continuous fracturing process reduces pumping time, lowers working fluid volumes, and decreases logistics costs.
