Patent number: 11015419Abstract: Bypass devices are disclosed for providing alternative flow paths within an annulus formed around a production string of a subterranean wellbore. In some embodiments, the bypass devices include inlet flow paths and outlet flow paths in fluid communication with the annulus so that fluids may flow through the inlet and outlet flow paths to bypass a blockage in the annulus. The bypass devices are also configured to avoid internal blockages within the internal flow paths defined by the inlet flow paths and outlet flow paths.Type: GrantFiled: May 10, 2019Date of Patent: May 25, 2021Assignee: BP Corporation North America Inc.Inventors: Michael J. Foster, Kevin Whaley, Patrick Keatinge

Patent number: 10941640Abstract: Provided is a multi-functional well completion apparatus and method of operation thereof that offers the ability, in a single trip and with limited running tool manipulation, to perform a sand control frac or other fluid stimulation operation and reverse out operations that has improved reverse out flow rates. Furthermore, a combination of dropped balls and hydraulic pressure open one or more sleeves for selective access to a plurality of isolated zones. Additionally, a combination of concentric pipe and internal flow paths creates a reverse flow path. This reverse flow path provides a live annulus during treating, the ability to take returns, and the ability to reverse excess proppant from the wellbore.Type: GrantFiled: August 28, 2019Date of Patent: March 9, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Thomas J.

Patent number: 10920528Abstract: A pressure response fracture port tool and method for its use reliably provides a noticeable indication at surface to an operator as to when the flow port is opened. The tool includes an outer housing and a sliding sleeve which resides within the outer housing. The outer housing has a first and second set of flow ports. The inner mandrel moves between a first position and a third position to expose the flow ports to the wellbore. The first set of flow ports, with its smaller area relative to the second set of flow ports, creates a noticeable pressure increase or spike that can be observed at surface when exposed to the wellbore. The second set of flow ports creates a noticeable pressure drop when it is exposed to the wellbore.Type: GrantFiled: March 11, 2019Date of Patent: February 16, 2021Assignee: Watson Well Solutions, LLCInventors: Roger Watson, Nevin Dahl
