Circular Cement Expansion/Shrinkage Test Kit

Comprehensive kit simulates slurry expansion and shrinkage in an annulus
The Grace Instrument M1520 Circular Cement Expansion/Shrinkage Test 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, plastic 1-inch tall block, and complementary 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. To run a test, cement slurry is poured into the mold and it is measured with the included micrometer. After the sample is hydrated, the slurry will expand or shrink. (The mold can expand due to the vertical slit in its outer ring.) A final measurement is taken and calculations are performed to determine the expansion or shrinkage of the outer ring’s circumference. Optimal cementing solutions can be engineered using the volume change results gathered from using this test kit.

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 several Grace Instrument high-temperature curing chambers, consistometers, and water baths (sold separately). (Contact Grace Instrument for exact model numbers of compatible units.)

The M1520 is compliant with API Recommended Practice 10B-5 (RP 10B-5).
