Stage Completions uses new tech for record Eagle Ford well

By Luke Geiver | June 06, 2017

Stage Completions has broken a hydraulic fracturing record in South Texas. The Calgary-based completions company has finished a company-best 117-stage well in the Eagle Ford. Stage deployed its Bowhead II single-point entry technology for the job. To frack the well, Stage needed 160 hours. Roughly 12 million pounds of sand and 361,000 barrels of fluid was used. The job did not require coiled tubing or wireline.

The Bowhead II system utilizes a dissolvable ball on a collet that activates cementable sliding sleeves, according to the company. A constant ID is maintained throughout the wellbore, allowing for longer laterals, tighter spacing, higher pump rates and higher sand concentrations. The new version of the system has undergone a materials upgrade. An 8620 carburized material and tungsten was used on the valve profile.

“Our proprietary technology was built from the ground up to raise industry standards in single-point entry fracturing,” said Sean Campbell, president and CEO of Stage Completions.

The push by industry to complete wells without using coiled tubing or wireline is one of the drivers for Stage Completions new technology, the company said.

Since first launching the Bowhead II technology last year, Stage has secured commercial orders for its valves that are placed in the tubing string in multiple shale plays, including the Montney, Marcellus, Eagle Ford, Bakken, SCOOP/STACK and Permian.

In the Eagle Ford well that recorded 117 stages, an acoustic and pressure monitoring system was installed on the wellhead to confirm the sleeve engagement of the collets at every stage. The acoustics allowed the operator to establish a live stage count by watching the pressure increases that took place in the well bore as the individual collets were installed and activated in the sleeves.
