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

Coarse Grind Cement for Oil Well Cementing

Proceedings of Fall Meeting of the Society of Petroleum Engineers of AIME, 1971
Abstract This paper describes the performance properties of a retarded Class H properties of a retarded Class H cement that was developed by removing the fines from the cement powder. Such a cement should be useful for high-temperature cementing because of its increased thickening time.

Recent Development in Oil Well Cementing

Venezuelan Annual Meeting, 1959
Abstract The success of oil field cementing operations, whether for completion or remedial purposes, is a vital factor in determining the well's future productive life and the eventual return on the well owner's investment.

Chemical shrinkage of oil well cement slurries

Advances in Cement Research, 1995
The phenomenon of ‘gas migration’ in oil well cementing is believed to occur during the transition state between initial and final set of the cement. As part of an initial study to elucidate the mechanism of gas intrusion into the cementing material, the external and total chemical shrinkage of API class G cement slurries was measured for the first 48

The hydration of saline oil-well cement

Cement and Concrete Research, 1996
The effect of salt content on the properties of the oil-well cement cured at high temperature and high pressure was studied. DTA, TG, XRD and SEM techniques were employed in studying the cement hydration process. An attempt is made to elucidate the change in the properties of fresh and hardened saline cement slurry in terms of the changes in ...

Rheological properties of oil well cement slurries

Proceedings of the Institution of Civil Engineers - Construction Materials, 2012
The rheological properties, including yield stress, plastic viscosity, thixotropy and gel strength of oil well cement slurries incorporating six different chemical admixtures were investigated at different temperatures in the range of 23 to 60°C using an advanced shear-stress/shear-strain controlled rheometer.

Application of Nanotechnology in Oil Well Cementing

SPE Kuwait Oil & Gas Show and Conference, 2017
Abstract Nanotechnology provides a wide variety of methods to resolve industrial issues, which could not be addressed previously using customary methods. It helps enable researchers to alter properties of bulk materials at the nanometer scale.

Cementing Oil and Gas Wells

Transactions of the AIME, 1915
Foreword I herewith present some notes on the use of Portland cement to cement in thecasing, and for plugging, to exclude water from oil and gas, wells, and the methods employed. I have used my best efforts to make each step of theoperation of cementing wells perfectly clear.

Development of New Formulation of Geopolymer Cement for Oil Well Cementing

International Petroleum Technology Conference, 2016
Abstract In this paper, we report the results of the investigations on the effects of sodium hydroxide (NaOH) concentration and different ratio of silicate to hydroxide on the density, rheology and compressive strength of geopolymer cement system used in oil well.
