Abstract: A transfer part for holding an implant has a clamping portion for clamping connection with the implant. The clamping portion has a radial groove, a clamping ring and a force transmission element. The clamping ring is insertable into the radial groove to directly engage with the implant. The force transmission element secures the clamping connection against rotation. An inner ampule for receiving and securing a transfer part for holding an implant has an upper fixing portion and a lower fixing portion. The upper fixing portion reaches to a large surface recess in the ampule for insertion and removal of the transfer part, and has a laterally open indentation enlarging towards the recess adapted for the closely fitting insertion of the transfer part. The lower fixing portion has a laterally open indentation towards the recess adapted to receive the implant.

Abstract: The Equalizer Tandem Pin Puller is new and different because a driver will attach a steel 1¼? length 1? OD collar to the handle of the tandem pin handle, the collar is attached to a 24? steel chain, then the driver will attach a steel clevis hook that is attach to a 6 inch steel chain, that is attached to a 24 inch steel pipe with a 45 degree curve in the upper end of it with a 4¼? plastic grip on the bottom of the pipe and two 1¼? grips on the Tee, keeping pressure on the chain, the driver while in a standing position, will then by holding the end of the steel handle place the 5½? on the side of the trailer, about two inches up the side. Then he will pull upward on the handle, which pulls on the hook, which pulls on the collar that is attached to the handle of the tandem pin. This will release the pin, allowing the driver to adjust the tandems.

Abstract: A method for predicting the secondary porosity system (SPS) porosity, and thereby permeability, of a coal bed involves determining an initial condition in the coal bed, including an initial SPS pressure and an initial sorbed gas composition, determining a pressure strain effect due to increasing the SPS pressure to a value greater than the initial SPS pressure, and determining a sorption strain effect due to changes in the sorbed gas composition resulting from decreasing the methane content and increasing the content of a stronger adsorbing fluid (SAG) relative to the initial sorbed gas composition. Preferably, the method uses data from test injections of water and/or a weaker adsorbing fluid (WAG) and a SAG. The data is used in the inventors' model to compute a SPS porosity and an absolute permeability at a reference SPS pressure and a reference sorbed gas composition. Preferably, the reference pressure is atmospheric pressure.

Abstract: A process for recovering methane from a coal bed and/or sequestering a fluid more strongly adsorbing than methane (“SAG”) in a coal bed involves fracturing an injection well and cyclically injecting SAG with intervening shut-in periods. Even though the absolute permeability of the coal bed decreases with continued SAG sorption, the SAG injectivity, surprisingly and unexpectedly, increases while injecting SAG at pressures greater than reservoir pressure, but less than fracture pressure or fracture extension pressure. The increased injectivity is thought to be due to a reduction in near-well flow resistance.
