A Generalized Hydraulic Model for Propulsion Force Calculations in Radial Jet Drilling

SPE Drilling & Completion, 2022
Summary Radial jet drilling (RJD) involves drilling several small-diameter lateral holes from a single vertical wellbore to increase reservoir contact and production. RJD system components (diverter, flexible hose, and jetting bit) are conveyed to the target depth using coiled tubing.

Radial Jet Drilling: A Technical Review

SPE Middle East Oil & Gas Show and Conference, 2017
Abstract Radial jet drilling, RJD is an unconventional drilling technique that uses the jet energy of high velocity fluids to drill laterals with different geometries in both conventional and unconventional reservoirs. Many case studies are available worldwide have proven RJD as a viable alternative to traditional stimulation techniques,

A Feasible Method for the Trajectory Measurement of Radial Jet Drilling Laterals

SPE Drilling & Completion, 2019
Summary Radial jet drilling (RJD) is an unconventional drilling technology that uses high-pressure liquid jet to drill multiple radial laterals. It is a cost-effective alternative for bypassing damage zones near the wellbore, restimulating the production of old wells, and developing unconventional reservoirs.

Trajectory Measurement of Radial Jet Drilling Wells: Improved Tool and Data Processing

Journal of Energy Resources Technology, 2019
Abstract Drilling by high-pressure liquid jet, radial jet drilling (RJD) is a cost-effective technology to restimulate the production of old wells and the development of unconventional reservoirs. However, due to the unique process of 90 deg turning in the casing, hardly any traditional tool can be applied in the RJD trajectory ...
