Chandler Engineering Offers Model 5265MG Mechanical Gel Strength Apparatus

Critical Tool for Determining Potential Gas and Fluid Migration in Oil Well Cementing

BROKEN ARROW, OK – Chandler Engineering, a leader in drilling and completion instrumentation, has introduced the Model 5265MG Mechanical Gel Strength Analyzer that directly measures gel strength development of well cement slurries under downhole conditions.  

The Model 5265MG allows oil service companies, operators and their testing laboratories around the world to optimize cement slurries and to accurately determine the potential for annular gas and fluid migration. 

The Model 5265MG provides the most accurate simulation of dynamic slurry conditioning during placement phase, as well as the static gel phase of the operation. The unique design of Chandler’s Model 5265MG includes a precision motor coupled with a reaction force transducer that allows the instrument to precisely measure phase changes.

The motor is capable of precise speed control as low as 0.2 degrees per minute for the gel phase and up to 150 RPM for slurry conditioning. The Model 5265MG can operate at maximum temperature of 400°F (204°C) and maximum pressure of 20,000 psi.  

The Model 5265MG features a magnetically coupled shaft, which keeps the motor and measurement electronics outside the high-pressure/high-temperature environment. Reaction torque measurement ranges from 10Ibs/100ft² up to 1500Ibs/100ft².

The entire system is designed to fit into a standard single cell ultrasonic cement analyzer (UCA) or static gel strength analyzer (SGSA) cylinder.  Chandler recommends combining the Model 5265MG with its Quizix 5000 Series precision metering pumps.

Chandler Engineering is a leader in oil well cementing, viscosity, reservoir analysis and high-pressure high-temperature instruments. It focuses on serving the upstream oil and gas markets in exploration and production. Its products are used for oil well cementing, viscosity measurement, reservoir analysis and other applications such as pipeline transmission.
