Patent number: 11619116Abstract: Resonant sweeping frequencies are estimated for specific rock types, saturated with various formation fluids at reservoir conditions. A sequence and duration of resonant frequency sweeps and high amplitude low frequency vibration/agitation at each station is designed based on petrophysical and geomechanical properties, and in-situ stress conditions. Resonant sweeping and agitation is conducted as a multiple resonant frequency (fixed or variable) tool passes at optimal speed, which will be determined for specific reservoir type and downhole conditions. Resonant stimulation tool type, or combination of tools, is selected based on borehole size, reservoir parameters and resonant frequency requirements to maximize the efficiency of stimulation. Broad range of operating frequencies will allow to tune to resonant frequencies of various formation types (sandstones, limestones, shales, dolomites, and heterogeneous reservoirs comprised of the mixture of above lithologies).Type: GrantFiled: July 23, 2021Date of Patent: April 4, 2023Inventors: Natalya Ionkina, Valeriy Ionkin

Publication number: 20150021026Abstract: A stage tool operable with a plug is used for cementing a tubing string in a wellbore annulus. The tool can have a housing with a closure sleeve movably disposed in the internal bore of the housing. When pressure is applied downhole to the tool, a breachable obstruction on an exit port of the tool's bore opens and allows fluid such as cement slurry to communicate to the wellbore annulus. When cementing through the open tool finished, a plug deployed downhole lands on a seat in the closure sleeve, and applied fluid pressure in the tool's bore against the seated plug closes the closure sleeve relative to the housing's exit port. Rotational catches between the housing's bore and the closure sleeve prevent the closure sleeve from rotating. Preferably, an intermediate sleeve is used in the housing's bore and has rotational catches on each end.Type: ApplicationFiled: July 17, 2013Publication date: January 22, 2015Inventor: Richard L.

Patent number: 8807227Abstract: An apparatus for pressure-testing a tubular body may be installed in the tubular-body interior. The apparatus comprises an activation-device seat, one or more bypass ports, a J-slot with an indexing pin and a spring. When an activation device, for example a ball, lands in the activation-device seat, fluid communication through the tubular body is blocked, allowing pressurization. During pressurization, the activation-device seat moves downward, causing the spring to compress and the indexing pin in the J-slot to move to the bottom position. Upon depressurization after the test, the activation-device seat moves upward, causing to spring to decompress and the indexing pin the J-slot to move to the top position. Upward movement of the activation-device seat unblocks the bypass ports, thereby reestablishing fluid communication through the tubular body. The tubular body may be drillpipe, casing or coiled tubing that is installed in the borehole of a subterranean well.Type: GrantFiled: December 19, 2011Date of Patent: August 19, 2014Assignee: Schlumberger Technology CorporationInventors: Jeremie Fould, Joel Rondeau

Patent number: 8800655Abstract: A mechanical stage cementing tool that includes a mechanical opening and closing seat sleeve and a pin sub. The mechanical stage cementing tool may be converted to a hydraulic stage cementing tool by inserting a hydraulic tube assembly into the mechanical opening and closing seat sleeve at a hydraulic modification area and by adding a hydraulic seat to the pin sub. The stage cementing tool has a running-in-hole position, an open position, and a closed position.Type: GrantFiled: February 1, 2011Date of Patent: August 12, 2014Inventor: Michael E. Bailey

Publication number: 20140202697Abstract: Methods for improving the bonding of a cement sheath to a tubular body in a subterranean well involve anchoring elements mounted on the outside surface of the tubular body—in the annular space between the tubular body and the borehole wall. The cement contains an expansive agent that causes the cement to expand after it sets. The anchoring elements are mounted such that an angle exists between the elements and the tubular-body surface, thereby providing resistance to cement sheath movement away from the tubular-body surface.Type: ApplicationFiled: January 22, 2014Publication date: July 24, 2014Applicant: Schlumberger Technology CorporationInventors: Simon Gareth James, Alice Chougnet-Sirapian

Patent number: 8783351Abstract: A cementing tool (20) capable of being installed in a casing string (10) and configured to selectively permit the flow of cement through one or more ports (34) in the tool is provided. The ports (34) are normally sealed by rupture disc assemblies (36) comprising a rupture disc (62) that can be opened to permit flow of cement through the casing string central bore (32) and into the annulus (14) defined by the casing string (10) and the downhole formation (16). The cementing tool (20) is particularly useful during cementing operations in which the annulus (14) has become blocked by a collapsed portion of the formation by allowing the obstruction (104) to be bypassed and the flow of cement (100) into the annulus to be continued without substantial interruption. Tool (20) may also be used in multistage cementing operations.Type: GrantFiled: June 21, 2011Date of Patent: July 22, 2014Assignee: Fike CorporationInventors: Lindsey Lee, Gene Hill, Eddie Malcolm, Jeffrey A.

Patent number: 8776875Abstract: For use with a top drive power unit supported for connection with a well string in a well bore to selectively impart longitudinal and/or rotational movement to the well string, a feeder for supplying a pumpable substance such as cement and the like from an external supply source to the interior of the well string in the well bore without first discharging it through the top drive power unit including a mandrel extending through a sleeve which is sealably and rotatably supported thereon for relative rotation between the sleeve and mandrel. The mandrel and sleeve have flow passages for communicating the pumpable substance from an external source to discharge through the sleeve and mandrel and into the interior of the well string below the top drive power unit. The unit can include a packing injection system and novel seal configuration.Type: GrantFiled: September 10, 2013Date of Patent: July 15, 2014Assignee: Mako Rentals, Inc.Inventors: Kip M.

In some embodiments, the methods and systems involve mounting a dual phase mixture generator on a transportable platform wherein the dual phase mixture generator comprises a mixing chamber connected with at least a first inlet, a second inlet, and a first outlet. A first container and a first pump are also mounted on the transportable platform wherein the first pump is operably connected with the first container. The transportable platform and the mounted equipments are then deployed at a wellsite. A base fluid is pumped into the first inlet under high pressure, and a gas is pumped into the second inlet under high pressure. The base fluid and the gas is combined in the mixing chamber to generate a high pressure dual phase mixture, which is then discharged via the outlet.Type: ApplicationFiled: January 27, 2014Publication date: May 22, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Brian Goddard, Roger Keese
