The challenges and risks with formation water breakthrough

The Roxar Subsea Wetgas Meter (SWGM) addresses the following operator challenges related to formation water breakthrough:

Increases risks of hydrate formation and therefore the need for increased Mono-ethylene glycol (MEG) injection
Jeopardizes hydrocarbon production due to water coning in the reservoir
Increases water flow and injected chemicals in lieu of hydrocarbon production
Pipeline scaling
Pipeline corrosion and erosion

The critical time window of a hydrate plug forming

There are field examples where the period from formation of water breakthrough, to hydrate growth and build-up and pipeline plugging is less than 20 minutes. Therefore, rapid, highly sensitive measurements are needed to capture the critical time window of a hydrate plug forming in order to take remedial actions to save the well. The Roxar Subsea Wetgas Meter has the ability to instantaneously measure extremely small changes in water volume fraction, as little as ± 0.00002 % (0.2 ppm).

Ensure reliability of hydrocarbon supply

The lack of real-time accurate hydrocarbon
measurements impacts allocation strategies and obligations. There is a need for a meter that provides accurate and robust measurements across multiple reservoir conditions. Only Emerson has dedicated subsea wetgas meters that address application specific challenges

Measurements on a well-by-well basis for production optimization

Case study offshore Egypt: Installation of Roxar Subsea Wetgas Meters has helped the operator to monitor water production profiles in real-time. By providing early warnings of the water produced, meters installed on the field have helped the operator and its partners save several wells from water breakthrough. It has also provided the operator with the necessary information to optimize the performance of its wells, leading to increased availability.
