Unconventional Reservoir Wells
Unconventional reservoirs are essentially any reservoir that requires special recovery operations outside the conventional operating practices. Unconventional reservoirs include reservoirs such as tight-gas sands, gas and oil shales, coalbed methane, heavy oil and tar sands, and gas-hydrate deposits. These reservoirs require assertive recovery solutions such as stimulation treatments or steam injection, innovative solutions that must overcome economic constraints in order to make recovery from these reservoirs monetarily viable. To help improve well economics in unconventional reservoirs it is important to evaluate wellbore architecture - including the cement sheath - as integral to well performance and total recovery. Halliburton cementing solutions are designed so that the cement sheath can help serve as a foundation for increasing ultimate recovery by addressing even the most challenging wellbore conditions including corrosive environments, high temperatures as well as large temperature differentials, high pressures and significant pressure differentials.
