    摘要: A method for accelerating start-up for steam assisted gravity drainage operations comprising the steps of: forming a steam-assisted gravity drainage production well pair comprising an injection well and a production well within a formation; beginning a pre-soaking stage by soaking one or both of the wellbores of the well pair with a solvent; beginning a pre-heating stage by heating the wellbores of the well pair; beginning a squeezing stage by injecting steam into the wellbores of the well pair; and beginning steam-assisted gravity drainage production.

    摘要: Methods relate to recovering coal bed methane. In-situ heating of coal facilitates desorption and diffusion of the methane for production of the methane through a wellbore. Water within fractures of the coal forms an electrical conduit through which current is passed. The heating relies at least in part on resistivity of the water, which thereby preheats the coal for the recovering of the methane.

    摘要: A hangtag is provided that is capable of hanging and securing a tool, such as a socket. The hangtag has a body portion having a front surface and a back surface, a hanging mechanism connected to the body portion, and a tool supporting mechanism also connected to the body portion for supporting a tool. The tool supporting mechanism includes first and second legs and a locking finger disposed between the first and second legs. The locking mechanism allows the particular tool to be reattached to the hangtag assembly after it is initially unlocked. This allows the hangtag to function as a storage and organization device for the tool.

    摘要: A rotary device has a releasable tool holder. A spindle with two ends has one end adapted to secure to a rotary device and the other includes a bore to receive a tool. A mechanism to retain and release the tool from the spindle bore is coupled with the spindle adjacent the bore end. At least two unlike retention members to apply a force on the tool in the bore are adjacent the bore. A sleeve surrounds the bore end of the spindle as well as the at least two unlike retention members. The sleeve has a common surface to apply a force on the at least two unlike retention members such that when the sleeve is axially moved along the spindle, the force is varied with respect to the position of the surface on the retention member. This force maintains the tool in the bore or enables the tool to be removed from the bore. A biasing member maintains the sleeve in a retention position on the spindle.
