Publication number: 20150034165Abstract: A fluidic modulator having a body forming a flow aperture between an inlet and an outlet, the flow aperture having a nominal diameter less than the inlet diameter and the outlet diameter whereby the flow aperture provides a constriction to a fluid flowing axially from the inlet to the outlet, and a moveable portion operable to alter the flow aperture. To create a modulated pressure pulse the moveable portion may be for example radially shifted in the flow aperture, rotated in the flow aperture, or the rotation of the moveable portion in the flow aperture may be controlled.Type: ApplicationFiled: July 29, 2014Publication date: February 5, 2015Inventors: David Kirk Conn, Christopher Paul Reed, Andrew J. Parry, Alain P. Dorel, Staffan Eriksson, Jonathan James, Stuart Alan Kolbe

Patent number: 8177526Abstract: Power and control logic configurations for gas well dewatering systems are provided. In one example, a reservoir is configured to contain hydraulic, lubricating fluid. An electric motor is configured to receive fluid from the reservoir for lubrication and a hydraulic pump powered by the electric motor is configured to receive fluid from the reservoir and pump the fluid into a hydraulic circuit. A positive displacement oscillating pump is powered by the hydraulic pump and configured to pump fluid from the reservoir to an outlet from the well. The electric motor and hydraulic pump receive the same fluid from the reservoir for lubrication and to create pressure in the hydraulic circuit, respectively.Type: GrantFiled: February 18, 2009Date of Patent: May 15, 2012Assignee: Schlumberger Technology CorporationInventors: Michael A.

Patent number: 8127835Abstract: A hanger system is provided for supporting a cable-supported dewatering pump in a gas well. A dewatering pump is supported in a downhole location by a cable. A cable hanger bears the weight of the cable and the weight of the dewatering pump. A pulling tool is configured to detachably connect to the cable hanger and to support the weight of the cable hanger, cable and gas well dewatering system as it is pulled out of a seated position in the well.Type: GrantFiled: February 18, 2009Date of Patent: March 6, 2012Assignee: Schlumberger Technology CorporationInventors: Michael A.

Patent number: 8082991Abstract: A monitoring and control system for a dewatering pump configured to dewater a gas well is provided. A dewatering pump is driven at a first speed to pump fluid out of a well annulus. A fluid level detection device is configured to identify a change of fluid level in the well annulus occurring between a first time and a second, later time. A controller is configured to change the speed of the dewatering pump from the first speed to a second speed based upon the identified change in fluid level. Several embodiments of the fluid level detection devices are provided.Type: GrantFiled: February 19, 2009Date of Patent: December 27, 2011Assignee: Schlumberger Technology CorporationInventors: Michael A. Dowling, Jason Kamphaus, Harryson Sukianto, Alain P. Dorel

Patent number: 7999422Abstract: A linear actuator includes a substantially cylindrical magnetostrictive element disposed in a housing. A retainer is cooperatively engaged with the housing and an exterior of the magnetostrictive element such that relaxed portions of the magnetostrictive element are frictionally retained in the retainer. An actuator rod is functionally coupled to one longitudinal end of the magnetostrictive element. A biasing device is disposed between the housing and the retainer to maintain the retainer in lateral compression. The actuator includes magnets arranged to induce peristaltic motion in the magnetostrictive element.Type: GrantFiled: January 19, 2010Date of Patent: August 16, 2011Assignee: Schlumberger Technology CorporationInventor: Alain P.

Patent number: 7980311Abstract: Devices, systems and methods for equalizing pressure in a gas well are provided. A jar device is coupled to a pump deployed in a gas well between areas of low pressure and high pressure. The jar device includes a mandrel and a no-go sleeve. A jarring tool is operated to transfer an axial force onto the jar device that is large enough to shear a shearable connection between the mandrel and no-go sleeve and thereby cause the mandrel to slide from a first position to a second position with respect to the no-go sleeve. A seal that seals between the no-go sleeve and mandrel when the mandrel is located in the first position is unsealed as a result of the movement of the mandrel and thereby fluid communication is allowed between the area of high pressure and low pressure. This allows for easier retrieval of the pump.Type: GrantFiled: February 18, 2009Date of Patent: July 19, 2011Assignee: Schlumberger Technology CorporationInventors: Michael A.
