Abstract: Examples of the present disclosure relate to systems and methods for utilizing an inner diameter of a tool for jet cutting and hydraulically setting packer.

Abstract: A system for stimulating a well with an annulus formed by a string and a wellbore. The system includes an injection assembly with at least two zone isolation packers configured to set upstream and downstream of a target zone at pressures above a predetermined activation pressure, and unset at pressures below the activation pressure.

Abstract: The present application describes a velocity chamber to regulate a velocity of fluid between an outer diameter of a piston, and an insert to limit, reduce, etc. erosion against the tool and casing.

Abstract: A complementary valve (100) for a movable string (1) in a wellbore application, wherein the movable string (1) comprises: a flow activated valve (400) configured to open when a flow through a central bore (2) is less than a predetermined threshold and to close if the flow exceeds the threshold, and a pressure activated device (200, 300) configured to be activated when an activation pressure, defined as the difference between a bore pressure within the central bore (2) and an ambient pressure around the string (1), is greater than or equal to a first activation pressure and to be deactivated when the activation pressure is less than the first activation pressure. The complementary valve (100) is configured to open a fluid connection (111, 121) between the central bore and the ambient wellbore if the activation pressure is less than the first activation pressure, and to close the fluid connection when the activation pressure is equal to or greater than the first activation pressure.

Abstract: A valve for inclusion or insertion in a tubular includes a substantially cylindrical outer valve housing; an inner sliding sleeve mounted axially movable inside the valve housing; and a seat arranged for receiving a drop ball, dart or falling device. The seat is built in such a way that it can partially or completely be removed or drilled out from the valve. The inner sliding sleeve includes a first profile arranged at a first end of the inner sliding sleeve and a second profile arranged at a second end of the inner sliding sleeve, wherein the first profile and the second profile are configured to be engaged with an activating or shifting tool inserted and run in the tubular after the seat has been partially or completely removed or drilled out from the valve in order to operate the valve from an open to a closed position and/or vice versa.

Abstract: A system for stimulating a well with an annulus formed by a string and a wellbore, wherein the system includes an injection assembly, a normally closed injection valve, a normally open flow activated bottom valve, a sand control element, a mechanically operated sand control valve, a releasable anchor configured to be set in the wellbore downstream from the sand control valve.

Abstract: Zone isolation is a leading concern for operators that wish to fluidly treat a well. By utilizing a ported sliding sleeve assembly that is highly resistant to leaking after being opened and closed through multiple cycles a wellbore may be accessed at any ported sliding sleeve assembly location without plugging the wellbore below the ported sliding sleeve assembly and will allow any ported sliding sleeve assembly to be accessed in any order.

Abstract: A protective sleeve for a ball activated device, the ball activated device comprising a seat sleeve axially movable between an initial state in which seat defining members are configured to form a fluid tight seal with a ball and a final state in which the seat defining members are allowed to enter into a seat receiving recess such that the ball is permitted to pass. In the initial state, the protective sleeve extends axially from the seat sleeve over the seat receiving recess. The protective sleeve can be connected in the extension of the seat sleeve through a rotation lock, and ensures that particles and scaling do not build up in the seat receiving recess. The invention prevents that particles are collected behind the seat defining members and prevent these and other movable parts from moving. The protective sleeve is thus particularly suitable for applications such as cementing or fracturing.
