Thru-Tubing Case Study
PetroStar Services’ Thru Tubing was called on to complete a challenging well from a customer in the Permian. The challenge consisted of drilling 43 plugs, washing over and recovering a fish, then drilling the remaining 2 plugs. All of this on a 2+ mile lateral with a .21 Friction coefficient with an agitator. Challenge accepted!!
PetroStar Services deployed our Patent Pending X-Reach Technology and Top Caliper Thru Tubing supervisors to “get it done”. We drilled the first 43 plugs with our X-Reach extended reach tool maintaining a .19 Friction coefficient! With a new tool string, we washed over and recovered the fish in two runs. Utilizing the original X-Reach and motor from our first run, we then changed to a bit and drilled the remaining plugs while achieving an incredible .155 Friction Coefficient!!!
Thru-Tubing Patents and Patent Pending Tools
X-Reach Agitation Tool
Petrostar Services patent pending extended reach tool "X-Reach" was developed in house by our thru-tubing experts and available in 2-7/8" and 3.125" tools sizes and shown consistent performance to a .19 friction coefficient.
Petrostar Services patent pending velocity tool is an unlimited cycle circulating sub designed for stick pipe drill outs to increase annular flow without exceeding downhole tool capabilities. The tool is configured to open over the desired flow rate for downhole tools and is capable of pumping up to 8 bpm.
Petrostar Services Barium mill is specifically designed to improve rate of penetration when compared to conventional diamond cutter barium mills. The patented design provides a stepped increase of diameters and positioning of carbide cutters and appropriate positioning of fluid ports and channels, to provide removal of cuttings and cooling and lubricating of the cutting head, in turn providing more efficiency and a better rate of penetration when compared to conventional diamond barium mills.
