Journal of Canadian Petroleum Technology, 1972
Abstract Cementing operations in Arctic environments continue to require research on many unanswered problems. Laboratory studies and observation of field practices helped answer some of these questions. Areas of laboratory study were:electrical resistivities of neat and drilling mud contaminated cement.stability of

Ultrafine Cement for Oilwell Cementing
Proceedings of Low Permeability Reservoirs Symposium, 1993Abstract Ultrafine cements are particulate, cementitious grouting materials that were initially developed as a replacement for unacceptably toxic chemical grouts for Civil Engineering applications. Several basic types are available: ultrafine slag cement (M1), ultrafine Portland cement (M3) and ultrafine portland/slag (M5).

Dental Clinics of North America, 1971
The manifold uses of dental cements-as (a) luting agents, (b) cavity linings and bases, and (c) restorations for teeth—make them perhaps the most important materials in clinical dentistry. The research of the last 10 years has resulted in four main types, classified by matrix-forming species: (1) phosphate, (2) phenolate, (3) polycarboxylate, and (4 ...

Cementing v. not cementing the Monk endoprosthesis
Injury, 1982In a retrospective study, 45 patients who had Monk hard-top endoprostheses inserted with cement because of fresh intracapsular fracture of the femoral neck, were compared with 61 patients with uncemented prostheses. The average age, age-distribution and the preoperative condition of the patients were well matched in the two groups.

Expanding Cements for Primary Cementing
Journal of Petroleum Technology, 1966Abstract The expansion of cement and the effect of various expansive aids upon oil well cementing compositions have been investigated to determine the amount of expansion feasible and to observe the stability of cements displaying increased expansion.

Ultrasonic Cement Evaluation in Inhomogeneous Cements
SPE Annual Technical Conference and Exhibition, 1992Abstract Although large sized heterogeneities in the cement sheath may indicate zonal isolation problems, not much work has been done to quantify their influence on ultrasonic pulse-echo cement evaluation measurements. For these measurements, "large" means having a characteristic dimension greater than the wavelength of the ultrasonic ...

Cementing Multilateral Well With Latex Cement
Proceedings of SPE/IADC Drilling Conference, 1997SPE/IADC Members Abstract One of the latest techniques in enhancing the current production is multilateral well. A multilateral well is a well having one or more branches or lateral sections from its main bore. The lateral sections can be open-hole or cased-hole.

Cement distribution during post cementation
Journal of Dentistry, 1981Abstract The distribution of the cement around parallel-sided and tapered posts coated with cement, and when cement was inserted into the prepared post hole, have been compared. In every case coating the post with cement gave rise to an incomplete cement film. Rough-surfaced posts and tapered posts retained more cement than smooth parallel posts. The
