A method for characterizing one or more properties of a geological formation including brine, the method including inputting at least one first property of the geological formation into an equation of state (EOS) model, the EOS model accounting for a high temperature effect on the brine; solving the EOS model to determine at least one second property of the geological formation; and outputting the at least one second property to a display device.

Device and method to determine conductivity for high pressure-high temperature service

A method for characterizing one or more properties of a geological formation including brine and a dense vapor phase includes inputting at least one first property of the geological formation including resistivity of a vapor phase into a model including an equation of state (EOS) model, the model accounting for a high temperature effect on the dense vapor where that the dense vapor has a non-infinite resistivity. At least the EOS model is solves to provide data relating to at least one second property of the geological formation. The data relating to the at least one second property is output to a display device for visual inspection.

Method to predict dense hydrocarbon saturations for high pressure high temperature

A downhole device with compressive layer at the surface thereof. Such devices may be particularly well suited for survivability in the face of potentially long term exposure to a downhole environment. Techniques for forming protective compressive layers at the surfaces of such devices may include positioning devices within a chamber for bombardment by high frequency particles. As a manner of enhancing the compressive layer thickness and effectiveness, low temperature conditions may be applied to the device during the high frequency treatment.
