20120199341 | Segmented Collapsible Ball Seat Allowing Ball Recovery - A series of ball seat assemblies preferably used to open a series of sliding sleeves for formation access to a zone that is to be fractured allows sequential shifting of the sleeves with a single ball. The ball is guided by a tapered member with a lower outlet larger than the ball. The ball lands on the segments that are initially supported. Some leakage occurs between the segments but not enough to prevent pressure buildup to shift the sleeves. The tapered member closely fits to the segments to minimize leakage. Shifting the segments axially allows them to retract so the ball passes to eventually land on a non-leaking seat so that the zone can be fractured. The ball is recovered at the surface after passing the retracted segments and going through the undistorted opening in the tapered member. | 08-09-2012 |
20130025872 | Pressure Actuated Ported Sub for Subterranean Cement Completions - A tubing pressure operated sliding sleeve is used in cementing a tubular string. The sleeve is configured to hold closed as pressure builds to a predetermined value. When pressure is further raised a rupture disc blows and provides access to an integral piston disposed outside the sleeve. The back side of the piston is exposed to a low pressure or atmospheric chamber located between upper and lower seals. The sleeve thickness near the chamber can be made relatively thick to avoid flexing or bending under differential pressure because the net force to shift the sleeve is from differential pressure on the piston rather than the piston areas created by the upper and lower seals. | 01-31-2013 |

20130118762 | Wireline supported bi-directional shifting tool with pumpdown feature - A shifting tool for sleeves is supported on wireline or slickline and is pumped to the desired location by pressure from above delivered against the tool and passing around its periphery or against an articulated peripheral extending member that can optionally seal. Once in the vicinity of the desired sleeve to be shifted the shifting key is engaged to the sleeve and further applied pressure on the articulated peripheral seal shifts the sleeve in a downhole direction. The sleeve can also be shifted in an uphole direction with an anchor that grabs near the sleeve and a latch key that grabs the sleeve and is configured to retain grip as a motor moves the latch key uphole. Power can come from a wireline or can be locally provided if using slickline. The seal or extending member is retractable for tool removal or relocation. | 05-16-2013 |
20130199800 | WIPER PLUG ELEMENTS AND METHODS OF STIMULATING A WELLBORE ENVIRONMENT - Methods for preparing a wellbore casing for stimulation operations comprise the steps of cementing a wellbore casing in a wellbore, the wellbore casing having a downhole tool comprising a valve and an apparatus for restricting fluid flow through the valve, such as a ball seat, disposed above the valve. Actuation of the valve opens the valve to establish fluid communication between the wellbore casing and the formation. A plug element is disposed on a seat of the ball seat and a casing pressure test is performed. The plug element then dissolves or disintegrates over time increasing fluid communication between the wellbore casing and the formation, thereby preparing the wellbore casing for stimulation operations without additional wellbore intervention after the casing pressure test. In certain embodiments, during or after dissolution of the plug element, clean-out of the bore of the valve is performed by the plug element. | 08-08-2013 |
20140102703 | Pressure Actuated Ported Sub for Subterranean Cement Completions - A shifting sleeve has differential piston areas so that applied pressure displaces the sleeve against spring bias, which preferably is a series of Belleville washer stacks associated with modular mandrel components, to obtain the desired opposing force to the movement initiated with pressure applied to differential piston areas. An indexing feature is located between the sleeve and the mandrel passage wall and on a predetermined number of cycles disables the Belleville washer stacks from biasing the sleeve in an opposed direction as when pressure is applied. At this time the pressure in the mandrel acting on the differential piston area simply shifts the sleeve to open a lateral port so that fracturing through the cement that was earlier placed with the port closed can take place. | 04-17-2014 |
