Well Cementing Diagnosis From Top Cement Pulsation Record
Proceedings of SPE Annual Technical Conference and Exhibition, 2001Abstract The paper reports on a feasibility study on post-cementing quality control using recorded data from Top Cement Pulsation (TCP). TCP is a novel technique for preventing gas flow after cementing. In this method small hydraulic pressure pulses (usually 100 psi.) are applied repeatedly at the surface into the casing annulus starting

Coarse Grind Cement for Oil Well Cementing
Proceedings of Fall Meeting of the Society of Petroleum Engineers of AIME, 1971Abstract 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.

This chapter mainly introduces casing program design, casing strength design, cementing technologies, and well completion technologies. Casing program is the basis of drilling engineering which is to determine the casing levels, setting depth, top of cement, match of casing sizes, and hole section sizes. Casing strength design is mainly composed of the

Cement Pulsation Treatment in Wells
Proceedings of SPE Annual Technical Conference and Exhibition, 2002Abstract Cement pulsation is a novel technology for enhancing zonal isolation by applying low frequency, hydraulic, pressure pulses to the wellhead immediately after cementing. The treatment maintains the slurry in a liquid state, which transmits hydrostatic pressure downhole, and keeps the well overbalanced thus preventing early gas ...

The casing program of CCSD-1 Well was different from that of conventional oil drilling and water well drilling in two aspects: not only were the standards of casing program different but also the moving casing techniques employed. In oil drilling, a casing program of 508.0 mm (20 in.) × 339.7 mm (133/8 in.) × 244.5 mm (95/8 in.) × 177.8 mm (7 in.) was ...

Well cementing involves pumping a sequence of fluids into the well. Often these fluids, such as spacers and cement slurries, have non-Newtonian yield-stress rheology. After the cement slurry has been placed in the annulus, it hardens into a low-permeability annular seal.

Cementing Geothermal Steam Wells
Journal of Petroleum Technology, 1964Abstract Cementing deep, high-temperature oil wells where static temperatures range from 350 to 400F has become routine in the past decade. In the United States there were 271 wells drilled deeper than 15,000 ft during 1963. Many of these wells had static temperatures higher than 400F.

Cementing Practices for Thermal Wells
Journal of Canadian Petroleum Technology, 1966Abstract The introduction of steam as a means of stimulation for oil production haspresented many problems in oil well completions. Some of the difficultiesexperienced have been casing failures, pipe growth, cement failure and cementbond breakdown.
