Reservoir Pattern Surveillance

Use studioSL's data-driven surveillance technology to make low-cost operational decisions on mature floods. Our surveillance workflow provides ROIP distributions, forecasts of rate targets, shut-ins, reactivations, and/or producer-2-injector conversions. There is no tedious history matching, meaning that you can rapidly go from model inputs to model forecast results.

Flow-based Well Rate Allocation Factors

Using each well's historical rates, location, perforations, and major geological flow units, a surveillance model will quantify well-pair rate allocation factors (WAFs).

 

Well rates (shown as bubbles) are overlaid with well-pair allocation factors (shown as connections) between injectors and producers. Connection thicknesses represent the strength of the WAF their color is based on the injector they belong to (injector pattern) for the current month.

Remaining Oil in Place

Apply material balance to dynamic well-pairs to determine remaining oil in place (ROIP) and current reservoir pressures.  

 

Areas of high oil saturation are shown in orange and red while areas of low oil saturation are shown in greens and blues.  Active injectors are blue triangles and active producers are red bullets.  Shut-in wells are not shown.

Rapid Forecasting

Rapidly forecast various short-term production optimization scenarios such as new rate targets, well shut-ins or reactivations, producer-injector conversions, and infill drilling locations.

 

Historical oil rate is shown in blue with green bullets, while two 5-year forecast scenarios are also shown.
