20090006901 | Control Systems and Method Using a Shared Component Actuator - In one embodiment, a control system supports an unlimited number of feedback control loops all sharing control of a component. A component performance rate or “speed” is used as a common metric for negotiating control of the component. Each control loop continuously monitors a system parameter it is tasked with regulating, compares it to a setpoint for that system parameter, and “requests” a speed in relation to the deviation of the associated system parameter from the corresponding setpoint. A controller receives the requested speeds as dynamic inputs and selects one of the requested speeds according to predefined selection logic. The controller communicates the selected speed to an actuator, which causes the component to operate at the selected speed. In this manner, the control system in effect negotiates control of the component in a way that ensures that all of the system parameters are being managed within safe limits. | 01-01-2009 |

20120090852 | Apparatus and method for compensating for pressure changes within an isolated annular space of a wellbore - Pressure relief devices comprise a chamber having a piston disposed therein. One side of the piston defines a hydrostatic chamber in fluid communication with an outside environment, such as an isolated wellbore annulus, through a port. The other side of the piston defines a sealed or isolated chamber. The pressure relief device permits changes in pressure in the isolated wellbore annulus to be distributed into the chambers so as to either reduce the pressure within the isolated wellbore annulus or increase the pressure within the wellbore annulus, both of which lessen the likelihood that the change in pressure within the isolated wellbore annulus will damage wellbore components disposed therein. | 04-19-2012 |
20120119445 | Sealing devices having a non-elastomeric fibrous sealing material and methods of using same - Sealing devices such as packers comprise a sealing element having one or more non-elastomeric fibrous sealing material layers formed by a plurality of fibers. The plurality of fibers may comprise one or more of natural material, metallic material, plastic material, or other non-elastomeric sealing material. The non-elastomeric fibrous sealing material layers may be formed by weaving the plurality of fibers, braiding the plurality of fibers, or forming a fibrous mass of the plurality of fibers. During operation, the non-elastomeric fibrous sealing material layers are radially expanded causing compression of the non-elastomeric fibrous sealing material layers. As a result, at least a portion of the air volume within the non-elastomeric fibrous sealing material layers is displaced by non-elastomeric fibrous sealing material causing the sealing element to engage a sealing surface, thereby forming a seal. | 05-17-2012 |

20130032354 | ANNULAR PRESSURE REGULATING DIAPHRAGM AND METHODS OF USING SAME - Downhole tools comprise a housing chamber with an expandable member disposed therein. An interior of the expandable member is in fluid communication with an outside environment so that hydrostatic pressure can act on an inner wall surface of the expandable member. The outer wall surface of the expandable member partially defines a sealed chamber within the housing chamber such that expansion of the expandable member due to an increase in hydrostatic pressure causes the volume within the sealed chamber to decrease, thereby energizing the sealed chamber. Thus, an increase in hydrostatic pressure within an outside environment is compensated. Further, when the hydrostatic pressure within the outside environment decreases, the energized sealed chamber causes contraction of the expandable member, thereby compensating for the decrease in hydrostatic pressure. | 02-07-2013 |
20130056207 | DOWNHOLE SEALING SYSTEM USING CEMENT ACTIVATED MATERIAL AND METHOD OF DOWNHOLE SEALING - A downhole sealing system includes a reactive material provided on a tubular and including an oxidizable substance; and a sealing material, wherein the oxidizable substance oxidizes when in contact with the sealing material.

20150114621 | Confined Volume Pressure Compensation Due to Thermal Loading - A pressure compensation system for enclosed spaces at a subterranean location changes volume with thermally induced solubility changes of a salt in water. The salt is held in an enclosure that is either rigid, or impervious and flexible or porous and flexible. As well conditions change and temperature increases, some of the salt goes into solution with a resulting decrease in volume that compensates for thermally induced volume increase due to temperature increase in the borehole. Conversely, a decrease in borehole temperature brings some of the salt out of solution for a volume increase to offset the volume decrease of the adjacent fluid to keep the pressure stabilized in the enclosed volume. In the porous enclosure embodiment the openings are sufficiently small to retain the salt even in solution. However, minimal net flows are anticipated for pressure compensation due to changing thermal effects. | 04-30-2015 |
20150114664 | Multi-stage Fracturing with Smart Frack Sleeves While Leaving a Full Flow Bore - Fracking ports are initially obstructed with respective biased sleeves that have an associated release device responsive to a unique signal. The signal can be electronic or magnetic and delivered in a ball or dart that is dropped or pumped past a sensor associated with each release device. Each sensor is responsive to a unique signal. When the signal is received the release device allows the bias to shift the sleeve to open the fracture port and to let a flapper get biased onto an associated seat. The flapper and seat are preferably made from a material that eventually disappears leaving an unobstructed flow path in the passage. The method calls for repeating the process in an uphole direction until the entire zone is fractured. The flapper and seat can dissolve or otherwise disappear with well fluids, thermal effects, or added fluids to the well. | 04-30-2015 |
20150122489 | SYSTEMS AND METHODS FOR DOWNHOLE COMMUNICATION - A method of conducting multiple stage treatments. The method includes running a string into a borehole.

Performing a treatment operation through the port; communicating from the radial exterior of the string or from a location downhole of the first and second sleeve assemblies to a second electronic trigger of the second sleeve assembly to trigger the second sleeve assembly into moving longitudinally relative to the string to close the port. | 05-07-2015 |
20150122493 | FRAC SLEEVE SYSTEM AND METHOD FOR NON-SEQUENTIAL DOWNHOLE OPERATIONS - A downhole communication and control system configured for use in a non-sequential order of treating a borehole, the system includes a string having at least three ports including first, second, and third longitudinally spaced ports arranged sequentially in a downhole to uphole manner in the string; at least three frac sleeve systems including first, second, and third frac sleeve systems arranged sequentially in a downhole to uphole manner in the string and arranged to open and close the first, second, and third ports, respectively, each frac sleeve system having self-powered, electronically triggered first and second sleeves; and, communication signals to trigger the first, second, and third frac sleeve systems into moving the first and second sleeves to open and close the ports. Also included is a method of completing downhole operations in a non-sequential order. | 05-07-2015 |
20150129218 | Fracturing Sequential Operation Method Using Signal Responsive Ported Subs and Packers - The method allows a pressure test of a string with external packers without having the packer setting apparatus exposed to tubing pressure so that at a later time and at a lower pressure than the pressure test pressure, the external packers can be set with annulus pressure opened to a piston that references a low pressure chamber. The packers can be set in any desired order. Thereafter, a circulation sub can be triggered to open to allow the fracking to start. Fracking each interval beyond the first in an uphole direction can be accomplished with pumping ever increasing balls to seats associated with sliding sleeves to open the sleeves in order. In cemented completions, after a pressure test, a ported sub can open on a timer or other signal to allow pumping a combination of a bridge plug and a perforating gun to the desired location. | 05-14-2015 |
