摘要： Particulate polymeric materials may be added to a cement slurry to adjust the linear thermal-expansion coefficient of the set cement. The coefficient of the set cement is optimized by considering the linear thermal-expansion coefficient of the casing, as well as the mechanical properties of the formation rock. When placed in a subterranean well having at least one casing string, cement sheaths with optimal linear thermal-expansion coefficients may be subjected to lower compressive and tensile stresses during downhole-temperature changes. Such cement slurries are particularly advantageous in the context of thermal-recovery wells.

摘要： A method and apparatus for performing sand control using fracturing is described. A curve is defined that correlates the percentage of flow through out-of-phase perforations (those perforations not aligned with fractures) with the fracture conductivity over formation permeability. Given a desired production flow, formation conductivity may be defined. This allows the well operator to perform the proper fracturing operation to achieve the desired fracture conductivity. Alternatively, after a well has been fractured, and sand production is observed, a critical flow rate and the corresponding drawdown pressure can be calculated to prevent sand production.

摘要： Methods and tools are described to reduce sanding including the steps of fracturing the cement sheath in a localized zone around the casing and having the fractured zone act as sand filter between the formation and openings in the casing, with the openings being best pre-formed but temporarily blocked so as to allow a conventional primary cementing of the casing. The fracturing step can also be used for remedial operation to reopen blocked formation or screens.

摘要： The present Invention relates to novel devices and methods to minimize the production of sand in subterranean environments; in particular, in poorly consolidated formations, sand is often co-produced along with the desired fluid (e.g., oil); sand production is undesirable, hence in the present Invention, elliptically shaped perforations of a particular orientation are created in the casing (or directly into the formation in the case of an uncased wellbore) that lines wellbore drilled through the formation, to improve near-wellbore stability of the formation, hence minimizing sand intrusion.

摘要： Methods for completing a well involve the use of computational models to design cement systems that are appropriate for the anticipated well conditions. Data from laboratory tests and/or numerical simulations may be employed in the models. The cement systems are designed to have a higher Young's modulus than the surrounding formation. In addition, the cement systems contain chemical-expansion agents that cause a microannulus to be deliberately formed at the cement/casing interface prior to the application of heat. The microannulus disappears during application of heat, pressure or both owing to casing expansion.
