Reservoir Surveillance with Streamlines
Reservoir surveillance is the association of injected and produced volumes. With streamlines, you can quickly go beyond classic reservoir surveillance methods to analyze and manage your water or miscible flood. StudioSL offers a simple and quick workflow that allows you to import historical production data, build a quick 2D grid, and get first quantitative representation of how volumes are allocated among wells. See our April 2008 SPEREE paper or our JPT Jan 2010 Distinguished Author article for more details. |
| Well location and production history. Use our Production Data Import tool in studioSL to quickly import historical production data, well locations and perforation data in OFM, Eclipse schedule file, POWERS, GeoSCOUT, or ResAssist format.

Simple or complex grid. Given well locations, build a quick 2D pancake grid or alternatively import a more complex 3D grid and associated properties. For a quick look at your flood, a simple 2D grid with average properties can already yield interesting results.

| Compute streamlines. With well locations, injection/production data known and a grid defined calculate the streamlines at desired times. Surveillance does not involved any transport calculations along the streamlines leading to quick simulations.

Flux Pattern Map. Now use Streamsim's patented Flux Pattern Map to quantify the strength and the allocation factors between wells. Since streamlines change with time, so will the FPmap, leading to a dynamic surveillance picture of your flood.

| Injection Efficiency. Once the well-pairs have been identified and the well-rate allocation factors between wells are known, studioSL can summarize the performance of your injectors via an injector efficiency plot. Each point on the plot represents an injector and is associated with a rate of offset oil produced. The IE-plot is powerful quick diagnostic of the efficiency of each injector in a field.

Conformance Plot. Knowing the well allocation factors through time it possible to plot the cumulative offset oil production associated with the cumulative volume injected at each producer. This plot is the well-known conformance plot, except that it based on dynamically changing patterns and WAF's and is therefore a more accurate reflection of the field performance.
