Patent number: 11867019Abstract: When cementing tubing in a borehole, a wet shoe track is created, and pressure testing of the tubing is performed. To do this, a wiper plug seats in a seat of an insert disposed in a first position in a flow bore of a tool. The insert is released and moved toward a second position in the flow bore in response to the first pressure applied against the seated wiper plug. A collar disposed on the wiper plug seats on a second seat disposed uphole of the first seat. The tubing is pressure tested by applying pressure down the tubing against the wiper plug with the collar seated in the second seat. Fluid communication is then established through the flow bore downhole of the wiper plug, the first seat, and the second seat by removing the collar from the wiper plug. This can create the wet shoe track.Type: GrantFiled: February 24, 2022Date of Patent: January 9, 2024Assignee: Weatherford Technology Holdings, LLCInventors: Craig A. Wright, Zachary S. Trine

Patent number: 11834917Abstract: A sleeve can be used as a stop collar on tubing. A fusible element disposed about the inside or outside surface of the collar can be accessed by electrodes via the at least one access point in the collar. An insulator insulates the fusible element from the collar, while the electrodes apply electric current to the fusible element. A fusible material of the fusible element is heated to melting in response to the applied electric current and affixes the collar to the tubing with a metallurgical bond formed from the melting and re-solidifying of the fusible material inside a space between the first circumferential surface of the collar and the opposing circumferential surface of the tubing. The fusible material can be heated to melting directly with the electric current, or an ignitable material activated with the electric current can melt the fusible material.Type: GrantFiled: May 11, 2018Date of Patent: December 5, 2023Assignee: Weatherford Technology Holdings, LLCInventor: David W.

Patent number: 11815380Abstract: Near-Infrared (NIR) filter photometry is used to calculate component concentrations in multiphase flows. The disclosed methodology adapts the Beer-Lambert law for nonhomogeneous immiscible mixtures (such as oil and water) by modeling the fluid layer as a nonhomogeneous distribution of its components and deriving a mathematical relationship between measured absorbances, component path lengths, and non-homogeneity factors. The methodology is integrated into a multi-channel filter photometer to measure phase concentrations in oil-and-gas pipelines. The system is proven more accurate than current state of the art based on data from simulations, multiphase flow laboratories and field trials.Type: GrantFiled: September 2, 2022Date of Patent: November 14, 2023Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Vijay Ramakrishnan, John Lievois
