Abstract: A method may include preparing a map of cement quality for one or more intervals of a wellbore; determining anticipated regions of fluid communication and anticipated regions of zonal isolation from the map of cement quality; and designing a stimulating treatment based on the presence of regions of fluid communication.

Abstract: Cement slurries are prepared that comprise water, a hydraulic cement and particles of an oil-absorbent material. The particles are present in an amount sufficient to alter a property of a non-aqueous drilling fluid. The cement slurry is placed in a subterranean well, whereupon the slurry contacts residual drilling fluid on casing and formation surfaces. The oil-absorbent material in the cement slurry may reduce the mobility of the drilling fluid, thereby improving zonal isolation.

Abstract: Methods may include recording pressure and/or temperature data at two or more time points in a region adjacent an isolated zone in a wellbore created by one or more isolation devices; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data. Methods may also include injecting a fluid into an isolated zone in a wellbore created by one or more isolation devices; recording pressure and/or temperature data at two or more time points in a region adjacent the isolated zone; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data.
