Formation Damage & Well Treatment Evaluation System

Manufacturer: Vinci Technologies
Model Number: FDS-350

The FDS350 system enables to perform (a) liquid permeability measurement, (b) static filtration tests, (c) mud invasion evaluation and (d) stimulation tests on a formation sample at reservoir conditions of temperature and pressure. This instrument can be configured for the evaluation of the effect of different fluids on rock permeability such as drilling fluids (water-based or oil-based mud), cement effluents, chemical wash treating fluids and acid corrosive treating fluids. Initial permeability, return permeability, brine sensitivity, critical flow velocity, acid stimulation, mud filtrate invasion can be monitored with this system. Drilling mud tests are performed under realistic field conditions by flowing the fluids tangentially to the face of the core, thanks to a special leak-off core holder . The system is configured with a mud recirculation pump based on a recirculating pump and a stirring accumulator for the mud to perform dynamic filtration tests so as to study erosion effects induced by the fluid flowing across the core face which contains proppant and other particulates. The mud pump flow rate of 6 l/min max ensures an efficient shear rate to simulate the real operating conditions. The computer controlled system is provided with a unique software that allows for operation both manual and automatic modes where all key components can be controlled including pump, valves and data acquisition. A test sequencer also permits to program and run test sequences automatically. The coreholder, air operated valves, mud pump and necessary plumbing are mounted in an airbath that has been designed to provide easy access of all components.
