As Oil & Gas Producers are driven to improve the rate of return from their assets, coupled with continued decline in discoveries of significant major reservoirs, the need to exploit more challenging reservoirs is growing. Specific to production enhancement or stimulation, both in vertical and horizontal wells, services companies are being challenged to more effectively and efficiently provide solutions to this market segment. Early efforts to stimulate multiple zones consisted of limited entry perforating, sand plugs separating zones, as well as retrievable bridge plugs and packers. Although these solutions have been effective, more speed and accuracy is needed.
Recent development of composite (coiled tubing drillable) bridge plugs has increased the speed and accuracy, yet more sophisticated solutions are required.
In his presentation, R. Kontarev will discuss different types of Pinpoint Stimulation Techniques for different types of completions in vertical and horizontal wells with the goal to optimize production for each well and field. The presented technologies have all been proven to be viable production enhancement methods that guarantee the highest ROI.
