US Classification:

1663051, 507271, 507140, 106816, 106638

Abstract:

Disclosed is a weighting agent comprising processed taconite, and methods of applying the weighting agents during the completion of subterranean wells. The processed taconite is ground such that the particle-size distribution is comparable to and compatible with other suspended solids in fluids such as, but not limited to, drilling fluids, lost-circulation-control fluids, spacer fluids, cement slurries and temporary pills.

International Classification:

G06F 17/11

US Classification:

703 2

Abstract:

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.

International Classification:

G01V 9/00

US Classification:

703 10

Abstract:

Embodiments disclosed herein relate to reservoir characterization techniques and methods for accurately predicting scale tendencies of formation fluids, developed with the newly discovered phenomena that extreme downhole conditions affect the properties of reservoir fluids, including both the brine and dense hydrocarbon gas phases. In one aspect, there is disclosed a method for producing fluids from a geological formation. The method comprises inputting at least one property of a geological formation into an equation of state (EOS) model. The EOS model accounts for bound water, a high temperature effect on the brine and a high temperature effect on the dense gas phase. The EOS model is solved to determine a character of fluids contained in the geological formation, and inputting a production condition or a plurality of production conditions into the EOS model. A character of the fluids is determined based on the determined character of the fluids in the geological formation and the input production conditions. The solution can be output to a display device. Planning of the production of fluids from the geological formation can be performed. Production conditions can be controlled or adjusted.
