Description
The fracture conductivity cell primarily consists of a main chamber, top and bottom pistons, and a pair of flow inserts situated on the right and left sides. Pressure is monitored through three taps that measure the pressure drop along the fracture. The upper and lower pistons feature three interconnected leak-off ports, which facilitate leak-off tests by creating a flow route through the cores at a right angle to the primary flow. The cell's heated steel structure maintains a constant, optimal temperature throughout the test, monitored by a thermocouple situated in a specialized port. Additionally, unique detachable end inserts allow for the simultaneous performance of conductivity and flow-back tests within the same chamber.
