ResAssist™ is an easy-to-use PC based graphical user interface (GUI) developed by Epic Consulting Services Ltd. that allows the user to interact with StreamSim’s powerful 3DSL® streamline simulator module in the familiar Windows™ environment thus eliminating the need to execute keyword commands normally required to run 3DSL®. The combination of ResAssist™ and 3DSL® is an affordable alternative to conventional finite difference simulations when dealing with reservoirs that have production/injection displacements. It gives the user fast and practical results which can be used as is, or to initiate more in depth simulations using streamline or conventional simulation.

Streamlines and well allocation factors

Streamline images provide the user with a unique glimpse of the flow patterns that relate to injector/producer pairs. The movement of fluids in a reservoir are often more complex than anticipated. The streamline image can also display allocation factors that illustrate the allocation for a given producer relative to the injectors in the field and vice versa . The streamline plot coupled with the saturation plots give the user a good indication regarding infill well placement.

Dynamic reservoir conditions change flow paths

Conditions in the reservoir can be quite dynamic with varying injection and production offtakes. In the example shown on the left, note the area of influence (orange) of the injector at the bottom. In the image on the right, increased offtake by the producers to the east result in the (orange) injection being diverted.

Water injection efficiency plots

ResAssist™ can also calculate and plot injection efficiency for a reservoir. 

ResAssist™ makes it easy to place new injector and producer infill wells into an existing model. The yellow wells shown are new injectors and producers that were inserted into the model forecast. ResAssist™ generates saturation and streamlines plots that include these new wells.
