  • Publication number: 20140305644
    Abstract: This invention relates to improvements in the current recovery of gases and oil liquids from an underground resource such as shale by means of hydraulic fracturing “Fracking.” The main improvements consist of increasing the yield of gases and oil liquids from drilled wells as well as eliminating the use of water which is a major problem. Mobile processing equipment, to upgrade the recovered resource and to convert it to a marketable product, is conducted where the resource is thermally extracted, resulting in the elimination of pipelines to conventional upgraders which produce an intermediate which is thence delivered by means of pipeline or rail to a far away conventional refinery. This new mobile approach which will be situated at or adjoining the drilled wells will lower capital and operating costs, reduce emissions, facilitate permitting, and help reduce public opposition to “Fracking.

  • Patent number: 8739866
    Abstract: A method for extracting bitumen and/or extra-heavy oil from an underground deposit is provided. The energy for producing the steam and for the electric heating is generated in situ, for which purpose part of the extracted bitumen and/or extra-heavy oil is burned in an industrial turbine with a downstream generator coupled to the turbine. The industrial turbine may be a gas turbine or a steam turbine. In particular the industrial turbine with downstream generator is assigned a waste heat recovery steam generator which serves for generating the steam and accordingly takes the form of a boiler. Through intermediate storage of the bitumen and/or ultra-heavy oil produced it is possible to implement a self-contained closed circuit which operates autonomously, independently of any external energy supply, using approx. 20% of the extracted bitumen and/or extra-heavy oil for the purposes of extraction.
