US Patent:

8555965, Oct 15, 2013

Filed:

May 6, 2010

Appl. No.:

12/774809

Inventors:

Indranil Roy - Sugar Land TX, US
Manuel Marya - Sugar Land TX, US
Rashmi Bhavsar - Houston TX, US
Chris Wilkinson - Houston TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 28/00
C23C 8/60
B05D 1/12

US Classification:

1662424, 1661771

Abstract:

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.

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.

US Classification:

703 10

Abstract:

One or more computer-readable media include computer-executable instructions to instruct a computing system to receive input as to physical characteristics of a resource recovery system and a resource reservoir; simulate fluid thermodynamics of the system and the reservoir; and output information as to phase composition, for example, in at least one dense phase affected by the resource recovery system. Various other apparatuses, systems, methods, etc., are also disclosed.

International Classification:

G06F 17/11

US Classification:

703 2

Abstract:

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.

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.
