Geothermal Well Cementing Technology

Proceedings of Southeast Asia Show, 1984
ABSTRACT The success or failure of drilling and completing Geothermal Wells depends reatly on available cementing technology. This requires not only having the knowledge of temperature stable competent materials but also a complete understanding of hole preparation, casing running procedures, mud displacement, lost circulation and the ...

Cementing materials for geothermal wells

Geothermics, 1972
Abstract In a well used in the search for endogenous fluids the opportunity exists to stop level of thermal waters of high temperature and pressure so that deeper levels can be reached, where it is inferred that there are fluids with better thermodynamic characteristics.

Cementing Arctic Wells Through Permafrost

Annual Technical Meeting, 1972
Abstract The cementing of surface casing through permafrost presents unique problems to completion engineers. The major factor is that subsurface temperatures may be below freezing to a depth of 1,500 feet or more. One more requirement for a satisfactory cement job is that the cement must set and develop sufficient ...

Expanding Cement - A New Development in Well Cementing

Journal of Petroleum Technology, 1966
PARKER, P.N., WAHL, W.W., MEMBERS AIME, DOWELL DIV. OF THE DOW CHEMICAL CO., TULSA, OKLA. Abstract Expanding cement is cement to which an expansive component is added. It is a true expanding cement, since the expansion occurs after the cement has set.

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.

Consequences of Salting Well Cements

Proceedings of International Petroleum Exhibition and Technical Symposium, 1982
ABSTRACT Salted cement remains active long after hydrating and hardening. In contact with less salted water, it exchanges salt for water through the permeable membrane continuum of the cement. Osmotic stresses in time produce multiple fractures.

Problems in Cementing Horizontal Wells

Journal of Petroleum Technology, 1990
" Any casing eccentricity becomes critical In horizontal wells because ofIts effect on flow velocity distributions In the wellbore." Introduction Horizontal wells are completed by one of four methods:open hole,casing packers,slotted or perforated liner, orcemented casing or liner ...
