Streamline Modeling

PetroTel specializes in streamline modeling which provides a deep insight into the flow behavior of reservoirs. Streamlines provide a direct measure of the sweep-out pattern between injectors and producers. This information can be used to optimize field performance.

The key principle behind streamline modeling is that the streamlines are tangent to the flow velocity. Thus, one can track fluid from an injector to a producer along streamlines. The use of streamlines models in the oil business is not new, simplified streamline models for homogeneous reservoirs have been in use for sixty years. Within the last ten years, new techniques have been developed to extend streamline models to heterogeneous reservoirs with variable well rates.

PetroTel uses sophisticated software tools to quantify and view streamlines. Streamline simulators take the results of a finite-difference simulation and visualizes streamlines.

This can be used to quantify sweep-out between injectors and a producer, as well as provide allocation factors for each well. This technology is ideal for infill drilling analysis, pattern balancing, and reservoir management.Under some conditions, it is possible to use a front-tracking simulator, rather than finite-difference simulator, as a basis for drawing the streamlines. Although a front-tracking simulator can be much faster than a finite-difference simulator, its use is generally limited to fluids which are nearly incompressible. streamline

Streamline analysis is a crucial aspect of PetroTel’s reservoir engineering workflow.

Our application of streamline analysis can be seen in oil fields all over the world. PetroTel has performed streamline analysis for the first waterflood project in Southeast Asia, the Dulang field in Malaysia. Other examples of PetroTel’s streamlines analysis are Prudhoe Bay in Alaska (SPE 63152), as well as the Lekhwair field in Oman (SPE 111143).
