PRODUCTION TESTING OF OIL AND GAS WELLS

Well testing

⚊ ONSHORE & OFFSHORE SERVICES

Clean up and well testing

Clean up is a preliminary operation which has the aim of eliminating, through the flow, all foreign fluids and solids in the well at the end of completion (e.g. the displacement fluid, the completion fluid).

The production test can be conducted on an oil & gas or geothermal well and can be differentiated based on: test flow parameters, fluids produced, purpose of the test.

⚊ WHAT IS THIS?

Production testing of oil and gas wells

Production testing (well testing) is an essential activity in the exploration of hydrocarbon and geothermal wells.

This term refers to measurements, under controlled conditions, of all parameters relating to the production of oil, gas and water from a well, to provide complete and accurate data on the performance of the reservoir.

Their interpretation is used to optimize field development.

Goals and objectives:

Nature and the amount of the fluids produced
Reservoir pressure and temperature
Characteristics of the fluids producing formation
Efficiency of the completion
Efficiency of the stimulation performed in the well
Reservoir geometry
Well drainage radius
Interference or correlation of producing layers among wells
Reservoir drive mechanism
Production capacity and formation damage
Productivity Index for oil wells
Open Flow for gas wells
