BROKEN ARROW, OK – The Chandler Engineering Model 5600-AUTO Shear History Simulator

greatly simplifies the process of preparing and loading water-based fracturing fluids into

rotational viscometers.

The rheology of fracturing fluids used by the oil and gas industry is affected by a range of factors

and conditions, and shear history simulators have proven especially useful for determining how

well these fluids perform in transporting proppants.

The process begins with a gel-based fluid that is placed into a pressurized supply reservoir that

delivers the fluid to an injection pump. The fluid is pumped through a combination of tubes at

various rates and durations to simulate pumping conditions experienced during fracture

treatments. Pressure is applied to the reservoir via an air regulator mounted onto the face panel.

The gel pump is constructed of high-pressure, corrosion-resistant stainless steel and is driven

by a servo mo
