    • The present invention discloses a selection process for installing underground workspace in or near a hydrocarbon deposit that is an appropriate workspace from which to drill, operate and service wells applicable to any of a number of methods of recovering hydrocarbons. The present invention includes a number of innovative methods for developing workspace for drilling from a shaft installed above, into or below a hydrocarbon deposit, particularly when the hydrocarbon reservoir is at significant formation pressure or has fluids (water oil or gases) that can enter the workspace. These methods can also be used for developing workspace for drilling from a tunnel installed above, into or below a hydrocarbon deposit. The present invention also discloses a procedure for evaluating the geology in and around the reservoir and using this information to select the most appropriate method of developing workspace for drilling from a shaft and/or tunnel.

    • In one embodiment, a method of hydraulically mining of oil sands from a well pair drilled into an oil sands deposit is disclosed. The wells are preferably installed from a protected underground workspace in or near the producing zone. The method of hydraulic mining disclosed herein includes: means of drilling production and tailings injection wells; means of augmenting hydraulic excavation for example by inducing block caving and/or wormholing; means of isolating the underground personnel areas from formation gases and fluids; and means of backfilling the excavated volumes with tailings. In one configuration, production wells are formed and lined with a frangible material, for example, a weak concrete or an inflatable epoxy-impregnated felt tube. Hydraulic mining of the full deposit thickness using a directional water jet bit begins at the far end of the drill hole and continues back in stages toward the well-head. When each stage is complete, the water jet can be used to disintegrate sections of liner to allow mining to proceed back towards the well-head. An aspect of the present invention is that it provides for backfilling of the mined volume in stages so that subsidence of the ground is avoided. Possible advantages of the hydraulic excavation method disclosed herein are the low amount of energy and water required, the high production rates possible and the tolerance to difficult geologies, to recover bitumen from oil sands as compared to thermal recovery methods such as SAGD and HAGD.
    • 在一个实施例中,公开了一种从钻井到油砂沉积物中的井对液压采油的方法。 井优选从生产区内或附近的受保护的地下工作区安装。 本文公开的水利开采方法包括:钻井生产和尾矿注入井的手段; 例如通过诱发块体塌陷和/或蠕虫洞来增加液压挖掘的手段; 将地下人员区域与地层气体和流体隔离的手段; 以及用尾矿回填挖掘的体积的手段。 在一种结构中,生产井和衬有易碎材料,例如弱混凝土或充气环氧树脂浸渍的毡管。 使用定向喷水钻头对完全沉积物厚度的液压开采从钻孔的远端开始,并逐步朝向钻井头继续回落。 当每个阶段完成时,可以使用水射流分解衬管的部分,以允许采矿向井身前进。 本发明的一个方面是它分阶段提供对开采体积的回填以避免地面沉降。 与诸如SAGD和HAGD的热回收方法相比,本文公开的液压挖掘方法的可能优点是所需的能量和水量可能高,可能的高生产率和难以测量的地质学的容忍度从油砂中回收沥青。
