Abstract: A downhole tool for connecting an interior of a casing to a formation, the downhole tool including an inner housing extending along a longitudinal axis X; an outer housing that encloses the inner housing and forms first and second chambers; a piston that separates the first and second chambers; a port that fluidly communicates an outside and inside of the downhole tool; and a stopping mechanism that prevents the piston from opening the port. The piston interrupts the fluid communication between the outside and inside the downhole tool.

Abstract: A setting tool for opening and dosing a sleeve inside a casing includes a body extending along a central longitudinal axis (X); a set of holding dogs located around the body; and a set of sleeve dogs located around the body. The set of sleeve dogs are configured to move along the central longitudinal axis (X) relative to the set of holding dogs.

Abstract: An electronic valve is placed in line with a casing in a well. The electronic valve includes a housing having plural ports that are blocked; a valve configured to initiate unblocking of the plural ports to allow fluid communication between the bore of the housing and an outside of the housing; and a deformable seat device having a body placed inside of the bore of the housing. The deformable seat device is configured to have a given diameter D3 for at least one of first and second ends of the body when the plural ports are blocked, and a smaller diameter when the plural ports are unblocked.

Abstract: An air lock device for sealing a casing located inside a well, the air lock device including a body having a bore and configured to be attached with each end to the casing; a moving element located inside the bore; and a blocking element connected to the moving element, the blocking element preventing a fluid to pass through the bore of the body. The moving element forms an inner chamber with the body in which the blocking element is trapped after the blocking element is punctured by the moving element.

Abstract: A steerable sub for controlling an angular orientation of a well tool in a well, the steerable sub including a housing; a steering element attached to the housing and configured (i) to partially extend out of the housing and (ii) to change an orientation relative to the housing; and an actuation mechanism connected to the steering element and configured to change the orientation of the steering element relative to the housing.

Abstract: A downhole isolation system for sealing a well, the downhole isolation system including a setting tool having an internal chamber; a first restriction element placed within the internal chamber; and a second restriction element placed within the internal chamber, separate from the first restriction element.

Abstract: A downhole tool for connecting an interior of a casing to a formation, the downhole tool including an inner housing extending along a longitudinal axis X; an outer housing that encloses the inner housing and forms first to fourth chambers; a first piston that separates the first and second chambers; a second piston that separates the third and fourth chambers; a port that is configured to fluidly communicate an outside and inside of the downhole tool; and a stopping mechanism that prevents the second piston from opening the port. The second piston is positioned to separate the port into an outer portion and an inner portion to interrupt a fluid communication between the outside and inside of the downhole tool.

Abstract: A time delay tool and method includes a mechanical restraining element, a reservoir for containing a reactive fluid, an actuating device and a wellbore device. When a stored energy is applied on the wellbore device, the actuation device is actuated and enables the reactive fluid in the reservoir to come in contact with the mechanical restraining element. While the mechanical restraining element undergoes a change in shape due to a chemical reaction, a stored energy applied on the wellbore device is delayed by a pre-determined time delay. The amount of the pre-determined time delay is determined by factors that include the reactive fluids, concentration of the reactive fluids, geometry and size of the mechanical restraining element.

Abstract: A refractive index sensor having one or more sources, an adaptive optical element or scanner, imaging optics, a sensing optic, and one or more detectors. The scanner impinges a signal from the source into the sensing optic and onto a sensor-sample interface at sequential angles of incidence. The detector response increases dramatically to signals reflected from the interface at corresponding sequential angles of reflection equal to or greater than a critical angle. The refractive index sensor also uses an input lens between the scanner and the sensing optic and uses an output lens between the sensing optic and the detector. A processor controls the sensor and can determine index of refraction of the fluid sample based on the detector response and scan rate. The sensor can be used in several operational environments from a laboratory to a downhole tool, such as a formation tester to determine properties in a borehole environment.

Abstract: A downhole fluid analysis tool has a tool housing and a fluid analysis device. The tool housing is deployable downhole and has at least one flow passage for a fluid sample. The fluid analysis device is disposed in the tool housing relative to the flow passage. Inside the device, one or more sources generate a combined input electromagnetic signal across a spectrum of wavelengths, and a routing assembly routes generated signals into the reference and measurement signals. At least one wheel having a plurality of filters is rotated to selectively interpose one or more of the filters in the paths of the reference and measurement signals.
