The purpose of well testing on development wells is to clean up and commission the well prior to its connection to the permanent production facility.

The testing of production wells involves in-line testing to measure the contribution of oil/water/gas from individual wells. Continuous production measurements are cost-effective, do not interfere with normal production and can improve reservoir understanding.

Wet gas meter

Wet gas meters are a cost-effective replacement of test separators. Wet gas flow meters provide continuous readings of the gas flow rate and the total liquid flow rate.

To achieve good accuracy (+/-5%), the service includes calibration with non-radioactive tracers and wet gas
pressure/volume/temperature (PVT) fluid sampling — a process accredited by DNV.

MPFM – Multiphase flowmeter

Expro offers Multiphase Flow Meters (MPFM) as a complementary service to existing portable Well Test Separators; the MPFM offers measurement without the requirement for phase separation.

Measurement can be made at wellhead or line conditions, allowing process fluids to be returned to the production process, without pressure reduction.

Typical applications include exploration & appraisal, commissioning & clean-up and routine production well testing operations.

In comparison, MPFM offers a small and compact footprint for portable well testing, the MPFM provides instantaneous measurement of rate and fraction with a wide operating range up to 98% GVF. Measurements are non-intrusive; the metre is solids-tolerant and offers a self-contained measurement solution. Well site commissioning, data processing and diagnostics are available in real-time through a local user interface.

Well site operation of the MPFM is supported with Expro’s proven well site PVT sampling and analysis products and services.

Clamp-on wellhead production surveillance

Our Expro Meters business provides wellhead production surveillance in support of core Expro well testing services.   These products and services utilise innovative, robust and cost-effective flow meters designed specifically for the types of multi-phase flows encountered in oil and gas production.

The non-intrusive clamp-on design of Expro Meters products allows easy, cost-effective deployment on new or existing installations with lower risk and operating costs than traditional flow measurement solutions.  As a result customers have the ability to address a broad range of greenfield and brownfield applications not previously considered good candidates for flow survey or permanent surveillance.
