Patent number: 9593553Abstract: A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port.Type: GrantFiled: December 12, 2013Date of Patent: March 14, 2017Assignee: Weatherford Technology Holdings, LLCInventors: Michael Shane Larisey, Patrick J.

Patent number: 9593560Abstract: In a fracking context the object that will ultimately block a passage in an isolation device is introduced into the zone with the bottom hole assembly.

Patent number: 9593575Abstract: A system and method for determining characteristics of a multiphase flow in a well/pipe are disclosed. The disclosed system and method use an optical immersion probe including a flow gap across which two or more types of radiation are transmitted in order to measure absorptions of two or more substances within the multiphase flow. Primarily, broadband ultraviolet (UV) and/or near infrared radiations (NIR) are utilized with the probe to gather absorption data at and/or around at least one of the water peaks and at and/or around one or more oil or oil-condensate peaks. This data may be utilized to calculate the water-cut of the multiphase flow over a wider range of gas volume fractions. Additionally, pressure ports having pressure sensors being located on the optical immersion probe for determining the impact pressures and flow rates of different phases of the multiphase flow may also be used.Type: GrantFiled: September 4, 2015Date of Patent: March 14, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Cheng-Gang Xie

Patent number: 9593578Abstract: A compressed-gas motor has a cylindrical inner chamber closed gas-tight at a first base surface, and a piston arranged so as to be movable along the cylinder axis in the cylindrical inner chamber. A first opening feeds a compressed gas into the inner chamber, and a second opening discharges a gas from inside the inner chamber. The openings are arranged in the cylinder casing of the cylindrical inner chamber, wherein the first opening is arranged between the second opening and the closed first base surface. The first opening is closable by a first piston part and the second opening by a second piston part. The compressed-gas motor has a resetting device which exerts a force on the piston in the direction of the first base surface of the cylindrical inner chamber if the second piston part does not completely close the second opening.Type: GrantFiled: August 10, 2011Date of Patent: March 14, 2017Assignee: Heraeus Medical GmbHInventors: Sebastian Vogt, Hubert Buechner

Patent number: 9593579Abstract: A crank circular slider mechanism that includes a multi-row reciprocating motion part and a one-row reciprocating part. The multi-row reciprocating motion part has a guiding part divided by a longitudinal groove into two rows parallel to each other, each of which has a hole for a circular slider. The one-row reciprocating motion part has a guiding part which can be inserted into the longitudinal groove of the multi-row reciprocating motion part along the thickness direction, so as to vertically traverse the multi-row reciprocating motion part. The guiding part of the one-row reciprocating motion part includes a hole receiving a middle circular slider. Two circular sliders are mounted in the same phase; the middle circular slider is sandwiched therebetween and is located with a 180 degree phase difference compared to them. Adjacent circular sliders are secured to each other.Type: GrantFiled: December 6, 2011Date of Patent: March 14, 2017Assignee: Beijing Sinocep Engine Technology Co., Ltd.Inventors: Ming Li, Zhengzhong Li, Yusheng Ma, Qingxu Wang, Lijun Guo
