摘要： A method of gravel packing a portion of a cased wellbore proximate perforations by using coiled tubing is disclosed. The portion of the wellbore containing perforations is isolated from the portion of the wellbore below the perforations. A connection apparatus is installed between a bottom hole assembly and the coiled tubing and this connection apparatus comprises a crossover tool. The bottom hole assembly is lowered into the wellbore using the coiled tubing until the bottom hole assembly is proximate the perforations. Then, a slurry comprising a gravel and a carrier fluid is pumpdown the coiled tubing and into the annulus between the coiled tubing and the casing. A second fluid which is compatible with the slurry is pumpdown the annulus between the coiled tubing and the casing while the slurry is above the connection apparatus between the bottom hole assembly and the coiled tubing. The second fluid and the slurry mixture reduce the slurry concentration prior to reaching the perforations.

摘要： A method of improving injectivity of fluid, particularly produced water, in enhanced hydrocarbon recovery is disclosed. The method includes introducing a fracturing fluid into the subterranean formation to create a fracture, and introducing proppant into the fracturing fluid to form a single layer of proppant in the fracture. The fracturing fluid can be formed from produced water. Alternatively, the produced water is introduced after a fracturing fluid, other than the produced water, has been introduced to create a fracture. By reducing the amount of proppant and by using much larger proppant, a larger flow path through the fracture is created, thereby increasing the injectivity of produced water.

摘要翻译： 公开了一种改进流体，特别是产生的水的注入性在提高烃回收率中的方法。 该方法包括将压裂流体引入地层以产生裂缝，并将支撑剂引入压裂流体中以在裂缝中形成单层支撑剂。 压裂液可以由生产的水形成。 或者，在引入除了生成的水之外的压裂流体以产生断裂之后引入所产生的水。 通过减少支撑剂的量和使用大得多的支撑剂，产生通过裂缝的更大的流动路径，从而增加生产水的注入能力。

摘要： A delayed gelling system useful in conformance control in the production of petroleum from subterranean formations, especially low permeability formations, is disclosed. The gelling system comprises a basic silica sol, an activator comprising a hydroxyl donor, and an optional syneresis inhibitor. In the disclosed method of using the gelling system, the gelling system may be pumped into formations with excessive water and/or gas production and thermally activated in the formation at downhole conditions to form a hard gel to reduce water and/or gas production.
