Abstract: A method of producing an image of at least one rock cutting. The method can include forming or obtaining a substrate having a patterned top surface. The method can also include using the patterned top surface of the substrate to support at least one rock cutting, controlling an image acquisition system to acquire at least one image of the rock cutting for storage and subsequent image processing.

Abstract: Processes and systems for monitoring one or more gases dissolved in a liquid. In some embodiments, the process can include introducing a fluid into an inlet of a sample cell, where the fluid includes at least one gas dissolved in a liquid. The fluid can flow through the sample cell such that at least a portion of the fluid flows past an optical window such that the fluid is viewable within the sample cell through the optical window. The fluid can be recovered from an outlet of the sample cell. An electromagnetic radiation signal can be emitted into the sample cell through the optical window for at least a portion of the time the fluid is viewable through the optical window. The fluid can be contacted with the electromagnetic radiation signal within the sample cell.

Abstract: A wellbore is plugged using a bismuth alloy. The wellbore is arranged so that a liquid bismuth alloy sets with an excess pressure of the plug relative to the borehole fluid pressure along a desired seal height distance.

Abstract: Described herein is an apparatus and methods for characterizing a fluid composition including exposing electrolyte to one fluid mixture, collecting a signal from an electrode in contact with the electrolyte, and simultaneously exposing the electrolyte to a second fluid, collecting a signal from a second electrode in contact with the electrolyte exposed to the second fluid, and comparing the signal difference between the electrodes with the Nerst equation wherein the temperature of the electrolyte is above 488° C. Carbon dioxide, nitrogen, and/or oxygen may be present in the fluid and/or the second fluid.

Abstract: Methods and apparatus are provided for the measurement of the compressibility of reservoir fluid. A piezoelectric material is coupled to a wall of a fluid chamber. Compressibility is derived from measured pressure changes to the fluid resulting from volumetric changes to the fluid chamber imposed by the mechanical strain of the piezoelectric material resulting from an applied electric field.
