Characterising Curing Cement Slurries by Electrical Conductivity

SPE Western Regional Meeting, 1998
Abstract Electrical conductivity is a parameter which can be used for monitoring the entire hardening process of oilwell cement slurries. The theoretical relationship between conductivity, porosity, cement chemistry, and ion content is discussed.

Cementing of Fragile-Formation Wells With Foamed Cement Slurries

Journal of Petroleum Technology, 1985
Summary Substantial regions of hydrocarbon production in California consist of formations that are very fragile, which imposes a density limit on the cementitious system used to cement the well pipe. Also, troublesome fallback problems have been experienced for years in these areas.

Yield Points in Oilfield Cement Slurries

SPE Eastern Regional Meeting, 1990
Abstract The determination of yield points in cement slurries is important in the overall description of slurry flow properties. Yield points affect both the start-up pressure after a temporary shut-down and void filling properties of cements.

Shrinkage of Oil Well Cement Slurries

Annual Technical Meeting, 1997
Abstract Gas leakage into and through the cemented annulus in oil and gas wells is a safety problem. The conditions for gas migration develop when the hydrostatic pressure of the hydrating cement slurry column slowly declines and finally falls below the pore pressure of a gas bearing formation. This pressure decline

Premixed Cement Slurry Solves Problems Associated with Conventional Oilwell Cementing

SPE Production Operations Symposium, 2005
Abstract Cementing technologies have advanced incrementally since the practice began in the early 1900's.While additives have been developed to meet specific downhole conditions and goals, the process by which cement is mixed has remained essentially unchanged beyond the initial development of mix-ing equipment specifically designed for ...

A New Cement-in-Oil Slurry

Southern California Petroleum Section Annual Fall Meeting, 1957
Fall Meeting of the Southern California Petroleum Section of AIME, 17–18 October, Los Angeles, California Abstract A new cement-in-oil slurry has been developed which has proven itself in the field to be an efficient and valuable aid in helping to reduce or eliminate water production in oil and gas ...

DETERMINATION OF DESIGN TEMPERATURE FOR CEMENT SLURRIES

Proceedings of SPE Latin America Petroleum Engineering Conference, 1992
Abstract One of the most important parameters to obtain for the appropiate cement slurry is the bottom-hole temperature which will determine the type and amount of additives needed in the slurry to achieve the required properties. At present, a new technique has been developed to determine the bottom hole circulating temperature based on
