MACS Instruction Manual

The Multiple Analysis Cement System (MACS II®) instrument performs static gel strength tests on cement slurry samples. The MACS II instrument conducts these tests under simulated down-hole pressure and temperature conditions to determine the Zero Gel Time/Transition Time (SGS/Time) of cement:

  • The MACS II instrument accepts a sample of cement slurry and applies a controlled set of temperature, agitation, and pressure parameters that simulate the down-hole conditions of a well. During testing, it monitors, controls, and records these parameters to form a data set. This data can then be analyzed to assist in predicting the performance of cement slurry in a well.
  • If a situation exists that a well presents particular problems or special conditions of temperature and/or pressure, the MACS II instrument can assist to minimize possible problems by providing a safe and controlled environment in which to test different cement slurries for the drilling process.
  • Maximum Temperature for the MACS II analyzer is 600˚F.
  • Maximum Pressure for the MACS II analyzer is 30,000 psig.

Ordering Information

Order Part Number 101677665 – MACS II Multiple Analysis Cement System (computer not included)

Features

  • Capabilities - 600°F temperature and 30,000 psig.
  • Pressurizes with water.
  • Slurry cup has an isolation volume chamber in the top to reduce risk of contamination.
  • Uses a conventional-style slurry cup.
  • Three heater bands. Good heat control.
  • Variable speed rotation which allows for more meaningful testing of muds, thixotropic slurries and gels with long delay times.
  • No time limit on the test duration. Time is dictated by set time of the cement. Plumbing allows for chilled water circulation for low-temp testing Magnetic-Drive system mounted to the top out of the path of routine operations.
  • Drive system is completely isolated from the test chamber. Not required to remove/replace the measurement system for each test.
  • The pressure vessel is on a hydraulic lift and it lowers away from the head and moves forward for inserting/removing the slurry cup. Slurry cup volume is same as that for a HTHP Consistometer.
  • Completely computer controlled. Fully automated start-up, conditioning, gel strength testing, and shut-down.
