Model 7170 Lost Circulation Material Apparatus

Model 7170 Lost Circulation Material Apparatus
A Critical Tool for Oil Well Cement Testing

The Chandler Engineering Model 7170 Lost Circulation Material Apparatus is an addition to Chandler Engineering’s world leading line of equipment. The Model 7170 provides a means to dynamically evaluate the performance of lost circulation materials under high pressure and high temperature conditions.

The apparatus is supplied with four slots with varying widths for use in determining bridging characteristics under pre-defined differential pressures. The slurry is stirred at 150 rpm using an impeller during heating and pressurization. Once steady-state conditions are achieved, differential pressure is created across the slot. A piston accumulator equipped with an LVDT is used to measure the liquid volume that passes through the slot. Data acquisition is provided via an Ethernet interface to Chandler Engineering Model 5270 software.

The Model 7170 Lost Circulation Material Apparatus provides safe, versatile, and adaptable technology with operating temperatures up to 400⁰F (204⁰C) and operating pressures up to 2000 psi (13.8 MPa).
