The project “Field Testing and Diagnostics of Radial-Jet Well Stimulation for Enhanced Oil Recov-ery from Marginal Reserves,” is a field demonstration project submitted by the Petroleum Research Recovery Center (PRRC) of New Mexico Tech (NMT). The industry participants of the project are Well Enhancement Services, LLC (WES), and Harvard Petroleum Company, LLC (HLLC).
The objective of the research is to field demonstrate a newly developed radial jet technology for production enhancement from low-permeability reserves. Diagnostic techniques including distributed pressure sensors and electrical resistivity tomography for monitoring lateral direction and placement will also be developed and field tested. It is expected that successful completion of this project will answer the following questions: (1) How to control and diagnosis the placement and direction of laterals during a radial jet enhancement? (2) Is lateral jet enhancement cost-effective for enhancing productions of marginal reserves? (2) What are the preferred reservoir conditions and lateral patterns for deployment of radial jet technology from an existing wellbore?
Well stimulation by radial jet enhancement is an attractive technology for enhanced oil recovery from both existing and new field developments. By using the most advanced coil-tubing technologies, lateral holes with different geometries can penetrate to compartmentalized formations that are left behind or bypassed during conventional waterflooding or within the less permeable oil zones that cannot be sufficiently drained by conventional processes. This research focuses on a field demonstration of radial jet enhancement and validation of diagnostic technologies for monitoring and optimizing the placement and direction of jet laterals. The field demonstration will be deployed at two oil wells (the Poker Lake Superior #001 and the Poker Lake Unit #061) at Eddy County and one gas well (Bluitt 16 State #001) at the Roosevelt County of New Mexico
The unique feature of the research is its multidisciplinary components and systematic approaches to mesh fundamental research with field demonstration for technology validation. The team members, including a research institute (PRRC/NMT), an oilfield service company (WES), and a small producer (HLLC), will provide a total of 55.3% cost share for the demonstration project. The successful completion of this project will provide a cost-efficient technology that can significantly increase production from existing marginal wells, which are mainly operated by small producers.
