Use studioSL's surveillance technology to make low-cost operational decisions on mature floods. Our data-driven surveillance technology provides ROIP distributions, ML-embedded forecasts of rate targets, shut-ins, reactivations, and/or producer-injector conversions. There is no tedious history matching, meaning that you can rapidly go from model inputs to model results.
For the Belridge Field in California, surveillance along with our floodOPT workflow showed a reversal in oil decline, while for the Wilmington Field in California our floodOPT workflow reduce oil decline from 20% to 2% over one year. In Argentina the oil decline for a water flood was reduced from 16% to 0% for the following 3 months.

Well locations, production history, and geology. Import historical production, well locations, and perforation data from OFM, Petrel, geoSCOUT, or AccuMap. Import 2D Zmaps from Petrel or Petra to build a 2D or 3D grid, or directly import a 3D geomodel from Petrel, Skua-Gocad, or other geomodeling software using Eclipse-like grid formats. |
Compute streamlines. With well locations, the injection and production history, and a grid defined, calculate the streamlines throughout history. The image to the left shows streamlines, as colored by originating injector, for one time interval. Surveillance does not involved the transport of fluids along the streamlines so calculations are fast and efficient. |
Flux Pattern Map. Collapse the streamline bundles between each well-pair and represent this as a graph. This is Streamsim's patented (US Patent 6,519,531) Flux Pattern Map to quantify the strength and the allocation factors between wells. Since streamlines change with time, so too will the FPmap, giving a dynamic pattern picture of your flood. These maps can be combined for a range of timesteps to then represent average patterns and average allocation factors over the time range. |
Injection Efficiency. Once well-pairs are identified and the well-rate allocation factors are calculated, studioSL can summarize the performance of the injectors via an injector efficiency plot. Each point on the plot represents an injector and is associated with an offset oil rate produced on the y-axis. The IE-plot is powerful diagnostic of the efficiency of each injector in a field. |
