    Abstract: The invention relates to a method for estimating pore pressure in subterranean shale formations such as gas- or organic-rich shale where pore pressure predictions based on either a resistivity log or a porosity-indicative log such as sonic tend to be inaccurate. The method involves combining the resistivity log with the porosity-indicative log using a Eaton formula to give an estimate of pore pressure which is accurate both for conventional water wet shale and for organic-rich shale.

    Abstract: A method of plugging a hydrocarbon well includes deploying a downhole tool to remove at least a portion of a casing at a section of well to be plugged. Deploying a blocking device downhole to block a bottom of the section of well to be plugged. Deploying a plugging material downhole onto the blocking device to fill an area to be plugged. Deploying an exothermic fluid downhole, wherein activation of the exothermic material liquefies the plugging material. Allowing the plugging material and the exothermic fluid to solidify form a cast-in-place plug that fills the section of well to be plugged.

    Abstract: A procedure and apparatus for cementing and cleaning a reservoir liner 3 comprises installing a reservoir liner using a drill string 4 which extends only as far as the distal end of a cased part 2 of the well, then, using the drill string, displacing cement into the reservoir liner using completion fluid whereby, when the cement is in place in the annulus around the reservoir liner, the reservoir liner is already clean and filled with completion fluid. A ball valve 6 at the top of the reservoir liner 3 is then closed before the cased part 2 of the wellbore is cleaned, to avoid debris entering the reservoir liner.

    Abstract: An apparatus for correcting for deviation of an ambient magnetic field direction from a reference direction in a marine environment includes: an instrument assembly vessel configured to move through the marine environment; an inertial reference direction device disposed on the instrument assembly vessel and configured to measure a deviation of an aiming direction of the instrument assembly vessel from the reference direction; a reference magnetic compass disposed on the instrument assembly vessel and configured to measure a direction of the ambient magnetic field direction with respect to the aiming direction of the instrument assembly vessel and to transmit the measured direction; and a processor configured to receive the measured deviation and the measured direction and to calculate the deviation of the ambient magnetic field direction from the reference direction using the received measured deviation and direction.
