During oil and gas production on an unmanned platform, it is a great challenge to monitor and sample the flow of the production fluids to ensure a high oil and low water production. In this project a Well Analyser and Sampler (WASP) will be designed. It is a tool which enables on-line readings of the oil/water/gas ratio, while automatically sampling the phases. This makes it easier for supervisors to make crucial decisions in relation to maximizing the production and minimizing costs.
The WASP consists of an automatic system to sample wells and to get a clear understanding of which well has water breakthrough.
The goal of the WASP is to provide the operator of the unmanned platform with knowledge about the oil/water/gas ratio much more frequently. The auto-sampling system also addresses the problem of generating consistent sampling, which leads to more reliable data.
The WASP enables monitoring of the oil/water/gas ratio of the production wells on an unmanned platform independently for each well. The WASP can take small samples for further analysis.
The WASP contains a mini 3-phase separator, which measures the amount of each phase. The phase-separator returns an on-line measurement of the fluid ratio to the production supervisor.
The single phase fluids can be automatically sampled a given number of times for each phase of each well. The sample containers are stored off-shore until all sample containers are filled, before they are manually replaced.
The project is funded by the Danish Hydrocarbon Research and Technology Centre
