摘要： 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.

摘要： Las modalidades descritas en la presente se refieren a técnicas y métodos para la caracterización de un yacimiento para predecir de manera exacta las tendencias a incrustaciones de los fluidos de formación, desarrollados con los fenómenos recién descubiertos de que las condiciones extremas del fondo de pozo afectan las propiedades de los fluidos de un yacimiento, que incluyen tanto las fases de salmuera como de gas denso de hidrocarburos. En un aspecto, se describe un método para producir fluidos desde una formación geológica. El método comprende introducir al menos una propiedad de una formación geológica en un modelo de ecuación de estado (EOS). El modelo de EOS tiene en cuenta el agua ligada, un efecto de la alta temperatura sobre la salmuera y un efecto de la alta temperatura sobre la fase gaseosa densa. El modelo de EOS se resuelve para determinar un carácter de los fluidos contenidos en la formación geológica, e introducir una condición de producción o una pluralidad de condiciones de producción en el modelo de EOS. Se determina un carácter de los fluidos basado en el carácter determinado de los fluidos en la formación geológica y las condiciones de producción de entrada. La solución puede devolverse hacia un dispositivo de visualización. Puede realizarse la planificación de la producción de fluidos desde la formación geológica. Pueden controlarse o ajustarse las condiciones de producción.

摘要： Compositions, apparatus incorporating a composition, and methods of use are described, one composition embodiment consisting essentially of one or more reactive metals in major proportion, and one or more alloying elements in minor proportion, with the provisos that the composition is high-strength, controllably reactive, and degradable under defined conditions. Compositions of the invention may exist in a variety of morphologies, including a reactive metal or degradable alloy processed into an alloy of crystalline, amorphous or mixed structure that may constitute the matrix of other composition, for instance a composite. Methods of using apparatus comprising a composition, particularly in oilfield operations are also described (e.g. flow and displacement control, sensors, actuators). This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

摘要： The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.
