Reservoir Management

Reservoir Management
Challenge

In order to know as much as possible about the sources of the oil and gas being extracted, reservoir managers need to use all the technological tools at their disposal. Reservoirs are constantly changing, especially after companies begin pumping operations, and the original 3D models created prior to drilling may not remain totally accurate. Continuing to update and develop the model can be very helpful in determining where additional wells should be drilled in order to obtain maximum yields with a minimum amount of difficulty. Knowledge of changes in reservoir activity is essential in well management, i.e. knowing where to choke back production and where to push harder.

Solution

Multiphase meters installed on each well as close as possible to the source provide valuable information beyond flow measurements. Changes occurring in the reservoir are reflected by the flow, and this feedback may be needed to initiate immediate remedial action to protect a well. In addition, reservoir managers can renew and enhance the models by comparing their original projections with well flow rates generated by multiphase meters. Using this information as well as the results of ongoing seismic testing, the managers gain a better understanding of the dynamics of the reservoir and how the fluids are flowing over time. Reservoir management suggests where to drill in the future – and where not to drill – to maximize yields while extending the life of the field.
