AI Technical Summary

Technical Problem

Conventional hydraulic well stimulation systems require extensive equipment and infrastructure, leading to large footprints that cannot coexist with drilling infrastructure on the same well pad, limiting well completion efficiency and increasing environmental and safety risks.

Method used

A dual-use pump system configured to switch between drilling and stimulation operations, allowing for automated well completion without the need for conventional high-pressure, high-volume well stimulation pumps and their associated infrastructure.

Benefits of technology

The dual-use pump system reduces equipment needs, minimizes greenhouse gas emissions, enhances worker safety, and increases well completion efficiency by allowing simultaneous drilling and completion operations on the same well pad.

Abstract

A method of using dual-use pump systems to reduce greenhouse emissions and completion costs that includes positioning a first pump system ("FPS") and a drilling apparatus ("DA") at a first well pad and a second pump system ("SPS") at a second well pad. The method includes performing a drilling operation using the FPS and the DA on at the first well pad, and then moving the DA to the second well pad to couple with the SPS. A completion unit is then coupled to the FPS at the first well pad. While the DA performs a drilling operation using the SPS at the second well pad, the completion unit performs a completion operation using the FPS at the first well pad.
