Description
The fracture conductivity cell mainly comprises a cell body, an upper and lower piston and a set of right and left flow insert. Three pressure taps monitor the pressure drop along the fracture. Three interconnected leak-off ports on the upper and lower cell pistons allow leak-off tests to be performed by providing a flow path through the cores in direction perpendicular to the main flow. The heated steel cell ensure an appropriate, constant temperature during the test. A thermocouple located in a dedicated port monitors the cell temperature. Unique removable end inserts enable a combination of conductivity testing and flow-back testing to be performed in the same cell.
