    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.

    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: 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.
