In many instances, the use of present spacer technology has resulted in mud contaminated cement. This paper discusses how the ARCO designed spacer system exhibits exceptional performance to clean out the wellbore and improve the quality of the cement job. Field examples from Offshore Gulf of Mexico show that this cleanout technology, together with pipe centralization and proper job execution, has resulted in good downhole placement of the cement slurry with minimal mud contamination.This success not only has drastically reduced the need for remedial cement work, but also has made the cement bond evaluation straight forward.This spacer technology has been successfully applied in water-based, oil-based and synthetic-based mud systems.Furthermore, the use of this spacer technology is now being expanded to other ARCO operations aro~nd the world.

During a period where both North American and International product markets are opening, the issue of calibration traceability has become a sig mficant issue in the calibration of heat flow meters [1,2] used in thermal conductivity measurements on insulation materials. This paper will discuss the approach of the Production Support Services Laboratory of Owens Corning/Fiberglas Canada Inc. in addressing traceability to U.S., Canadian and International standards orgamza tions. As a wide range of insulation products with varying thickness, density and R- values are tested in this laboratory, the calibration requirements may become quite elaborate. Included in this paper will be a techmcal discussion of the calibration stud ies and their findings performed on two different designs of heat flow meter appara tus. The calibration discussion is limited to a narrow temperature range typically used in the evaluation of insulation products to standard specifications.
