Case Study, Haynesville Trend, De Soto Parish, LA
A major operator and loyal user of the Tempress HydroPull utilized 2 3⁄8-in. coiled tubing as the conveyance method and milled a total of 57 frac plugs from a horizontal lateral nearly 10,000 ft. long to a total measured depth of 22,305 ft.
The BHA comprised 2 7⁄8-in. and 3 1⁄8-in. tools and consisted of a weld-on coil connector, a dual redundant back pressure valve, a hydraulic disconnect, a screen sub, a 3 1⁄8-in. Standard Flow-Maximum Impact Tempress HydroPull, a 3 1⁄8-in. Baker Hughes UltraMax™ motor, and a 4 1⁄8-in. Varel tri-cone rock bit. No short trips back to the KOP were utilized and two gel sweeps were utilized to clean debris from the wellbore at 3.1 to 3.4 bpm. One final sweep was utilized, pumping three bottoms up just prior to pulling out of the hole.
All 57 plugs were milled without any pipe-on-pipe chemical additives. The wellhead pressure ranged from 5,250 to 5,600 psi and the circulating pressure ranged from 8,000 to 8,500 psi. The HydroPull tool possesses the lowest differential pressure of any friction-breaking tool on the market. In high-pressure wells, this low differential pressure allows for higher pump rates at a given pressure, providing maximum BHA performance and highly effective hole cleaning.
The wellbore was particularly challenging with a 93° toe-up lateral and a wellbore temperature of nearly 36
