  • Patent number: 9194212
    Abstract: A downhole actuator or valve for inclusion in a downhole drill string used in a well includes an obstructing member, such as a piston, moveable between: a first position and a second position; and a retaining member, such as a ball, moveable between: a retaining position which retains the obstructing member in the first position; and, a release position which does not retain the obstructing member in the first position and/or allows or causes the obstructing member to move to the second position. The retaining member is moved in use between the retaining position and release position at least in part by centrifugal forces caused by rotation of the entire drill string within which the downhole actuator/valve is included. Thus, at least some control of the actuation of the downhole actuator/valve may be afforded by rotation thereof.

    Abstract: A rock core removal method and apparatus allows efficient, safe, and reliable removal of a rock core sample. An inner collet tube and an outer ground tube, within a drill tube, protect the core sample during drilling. At depth, the collet tube is raised with respect to the ground tube so that the conical wall of the ground tube pushes constricting fingers on the collet tube inward, gripping the core sample within. The collet tube and ground tube are then raised, rotated, or raised and rotated, applying the necessary force to break the core sample off of the substrate. After retracting the tubes, the collet tube is lowered with respect to the ground tube to release the core sample. An ejection rod then pushes the core sample out of the collet tube. The ground tube may also act as the actuating means for a quick-change drill-bit release feature.

  • Patent number: 6736224
    Abstract: A wellbore assembly is provided that is operable in wellbores in the range of six to six and one-half inches for obtaining large diameter cores, e.g., cores greater than or equal to two and seven-eighths inches in diameter. The wellbore assembly may preferably be utilized with drill pipe so that standard drilling rigs may be utilized in drilling and coring operations therewith. The drill pipe in accord with the present invention may be formed by modifying standard API drill pipe such as API four and one-half inch IF (Internal Flush) drill pipe in a special manner that renders the drill pipe still suitable for the type of drilling operations of interest and also suitable for handling by any drilling rig capable of using standard API drill pipe. Alternatively, the drill piper may be initially manufactured in accord with the specifications of the present invention.

  • Publication number: 20040065478
    Abstract: A device for preserving the orientation of a core is described. A core barrel is attached to a rotatable orienting rod. A plurality of projections are located on an inner surface of the core barrel. Three projections are grouped together and opposite from a fourth projection. A ratchet assembly is included at an end of the rotatable orienting rod opposite from the core barrel. The ratchet assembly includes a first body, to which the rotatable orienting rod is attached, a plate, a second body, and a biasing mechanism. A turning rod is mounted on the plate, which is located between the two bodies. The plate and the second body each have teeth which intermesh, but which slip if a clog in the core barrel inhibits rotation of the rotatable orienting rod.

  • Patent number: 6708784
    Abstract: The present invention relates to a method for a valve, which valve comprises a movable valve body (6) having a first side (9) facing a means for supplying pressurized fluid and influenced in the supply direction by a force from said fluid, and a second side (11) influenced in opposite direction by a force from said fluid, which valve is provided with at least one connection (8) connecting the first side (9) of the valve body with the second side (11) of the valve body, and also comprising a spring (20) for opening the valve by displacing the valve body from a closed position to an open position, said method comprising the following steps: a pressurized fluid is supplied to the valve in closed position so that the valve remains closed; the supply of pressurised fluid to the closed valve ceases, a force equalization then occurs between said first (9) and second (11) sides thereby enabling the spring to open the valve, and a pressurized fluid is supplied to the valve in open position and the valve remains open.

  • Patent number: 6659204
    Abstract: A pressure and temperature core sampler comprises a tool for recovering cores specifically enabling the evaluation of methane hydrate resources. Because methane hydrate tends to decompose under conditions of pressure decrease and/or temperature increase as the samples are retrieved to the surface, a coring tool in accordance with the present invention provides a self-contained system for retrieving core samples at or near in situ pressure while cooling the core sample. The coring tool is preferably a wire line retrievable device that provides for nearly continuous coring during the drilling operation.

  • Patent number: 6457538
    Abstract: A system of apparatus for use in a coring tool measures the height of a core sample being recovered and transmits data relative thereto to the surface of a formation concurrently during the coring operation. A transmitter of an electromagnetic ranging system rides atop a core sample being formed in the barrel chamber and a receiver member of the electromagnetic ranging system is fixed at a top end of the barrel it known distance above the transmitter. During the coring operation the transmitter transmits a fixed frequency signal to the receiver through drilling fluid disposed therebetween. The distance between the transmitter and receiver decreases and the amplitude of the transmitted signal changes as a function of the separation distance between the transmitter and receiver as the core sample enters the inner barrel and the height of the core sample within the barrel is determined as a function of time and depth.
