PetroQuip’s BigFoot toe sleeve makes impact in Anadarko Basin

PetroQuip Energy Services, an oilfield service company specialising in the design and manufacture of land and offshore downhole pressure control devices, has successfully run its revolutionary toe sleeve, BigFoot, in a recent horizontal completion for an independent operator.

The unique and patented design enables operators to run multiple tests at any maximum or desired pressure for as long as necessary. The toe sleeve can be opened at any time. These features can be coupled with the option of conducting multiple high-pressure tests and opening at a lower pressure. BigFoot also eliminates the need for coiled tubing to be run to initiate circulation.

Eight days after BigFoot was installed and cemented in the Anadarko Basin, the operator rigged up to test the casing with a test pressure of 9500 psi and then bled down to 0 psi. The first casing test was successful, so the operator chose to cycle through the remaining casing test chambers by pressuring up to 8500 psi then bleeding to 0 psi. The sleeve was opened during the final cycle at 4600 psi. The operator pumped into the formation with an injection rate of 11.5 bpm at 7200 psi with a total of 150 bbls injected before shutting down.

The operator reportedly saved tens of thousands of dollars and many hours of work on this job.

“This successful installation and operation of BigFoot was directly related to our careful attention to our customer’s needs,” said Bill Darnell, PetroQuip founder and president. “They asked us to design and build a toe sleeve that was more reliable and flexible than others in the industry, enabling them to test their systems as many times as they needed, for as long as they needed and at any pressure they required.”
