Comprehensive kit simulates slurry expansion and shrinkage in an annulus
The M1520 High-Temperature Annulus Cement Expansion/Shrinkage Measuring/Testing Kit is a comprehensive tool kit that simulates and measures cement slurry volume expansion and shrinkage in the annulus of an oil well. The M1520 kit is easy-to-use, compact, lightweight, and portable. It includes a stainless-steel ring mold, micrometer, micrometer stand, and complimentary carrying case.
The ring mold contains an inner and outer ring that simulates the same structure of the circular annulus between an actual bore hole and well casing. The cement slurry is first poured into the ring mold and allowed to fill the mold’s annulus. Next, an initial measurement of the cement volume between a gap on the back of the mold is taken with the included micrometer. The mold is then placed inside a bath, consistometer, or curing chamber. (This ring mold can withstand high-temperature testing conditions.) Once cured, the cement sample is remeasured using the micrometer placed in the included micrometer stand for extra stability. The difference between the initial and final measurements can be used to determine the expansion or shrinkage of the slurry in an actual annulus. Using these results, ideal cement compositions can be engineered to work optimally with the bore hole and well casing walls of the oil well.
The M1520 is a powerful testing tool. It can accurately measure cement slurry expansion and shrinkage characteristics, which can be then applied to real-life cementing applications. This product is compatible with most standard high-temperature water baths, curing chambers, and consistometers. It is also conveniently compatible with our several high-temperature curing chambers, consistometers, and water baths (sold separately). (Contact Us for exact model numbers of compatible units.)
The M1520 is compliant with API Recommended Practice 10B-5 (RP 10B-5).
