摘要： An articulated reaming tool is provided in casing or liner drilling on or through the tubular wall with the articulation occurring from within the tubular. Outer limit travel stops are contemplated to optionally be used to retain the elements or blades to the tubular. In the case of liner drilling the drill string has an exterior protrusion to engage the movable components that ream and extend them to increase the clearance for the tubular as the tubular advances when more hole is made.

摘要： A containment vessel is moved proximate to and preferably surrounding the wellhead, such that leaking oil enters an interior chamber of the vessel. A fluid pump of the containment system is actuated to flow leaking hydrocarbon fluid through a conduit toward a collection sump. A controller controls the speed or volume of a fluid pump to maintain suction force within the interior chamber, or the pressure at wellhead annulus site (PWAS) at a set point that is based on seabed pressure.

摘要： A method for reducing temperature of a bottomhole assembly during a drilling operation is disclosed, that, in one aspect, may include: drilling a borehole using a drillstring including a bottomhole assembly by circulating a fluid through the drillstring and an annulus between the drillstring and the borehole, pausing drilling, continuing circulating the fluid through the dill string and the annulus. The method further includes diverting a portion of the fluid from the drillstring into the annulus at a selected location above the drill bit to reduce temperature of the bottomhole assembly.

摘要： A fluid flow control apparatus includes a biasing member applying a biasing force to a closure member, and a sealing member receiving the closure member. A dampener operatively connected to the closure member resists a force applied to the closure member. A fluid seal is formed when the biasing member presses the closure member against the sealing member. The closure member and sealing member may cooperate to control fluid flow along a fluid conduit formed in a wellbore tubular. The apparatus may include an actuator that controls the force applied to the closure member. The actuator may adjust the biasing force, and/or the dampening force. Also, a controller control the actuator may be responsive to a signal generated at a surface location, a downhole location, and/or a signal generated by a sensor.

A cartridge may comprise a barrel wall defining a first bore, and a piston comprising at least one retractable pad positioned at least partially within the first bore. The barrel wall and the piston may define a first reservoir within the first bore, and a valve may be positioned and configured to regulate flow through an opening to the first reservoir. Related methods and devices are also disclosed.
