摘要： A method of producing heavy oil from a heavy oil formation with steam assisted gravity drainage. The method begins by drilling a borehole into a heavy oil formation comprising a steam barrier between a first pay zone and a second pay zone, wherein the steam barrier prevents a steam chamber to be formed between the first pay zone and the second pay zone. The steam barrier is then heated with a radio frequency. The steam barrier is then fractured to permit a steam chamber to be formed within the first pay zone and the second pay zone. Heavy oil is then produced from the heavy oil formation with steam assisted gravity drainage.

摘要： A process for sealing off one or more segments of a gravel packed well to reduce the production of undesirable fluids. The process includes the installation of a removable plug and the installation of a removable sealant at a location in the gravel packing to separate portions of the formation that produce desirable products from portions that produce less desirable products. A flow poison is then squeezed into the portion of the formation that produces less desirable products. With wireline or other low-cost wellbore workover systems, access is re-engaged with the preferred formation including removal of plugs and sealants without mechanical drilling. The process allows increased production of preferred fluids by preventing less or non preferred fluids from displacing the preferred fluids and also reduces lifting costs that would otherwise be expended for lifting and expenses related to separating and disposing of non preferred fluids.
摘要翻译：用于密封砾石填充井的一个或多个段的方法以减少不需要的流体的产生。该方法包括安装可移除的塞子以及在砾石填料中的位置处安装可移除的密封剂，以将形成理想产品的部分分离成产生不理想产品的部分。然后将流体毒物挤入地层中产生较不理想产品的部分。使用有线或其他低成本井筒修井系统，可以重新接合优选地层，包括拆除塞子和密封剂，而不需要机械钻孔。该方法允许通过防止较少或不优选的流体排出优选的流体来增加优选流体的生产，并且还减少否则将用于提升的起重成本以及与分离和处理非优选流体有关的费用。

摘要： Methods and systems for depth and radial orientation detection are provided. Methods for determining the depth or radial orientation of one or more downhole components include the steps of providing a target mass and a using a detection device for detecting the depth and/or orientation of the target mass. In some cases, the target mass is initially nonradioactive and then, after installing the target mass downhole, it may be irradiated to form a relatively short-lived radioactive target mass, which may then be detected with a radiation detector. In this way, the target mass acts as a depth or radial orientation marker. Where the target mass is situated downhole in a known radial relationship to another downhole component, the radial orientation of the other downhole component may be deduced once the radial orientation of the target mass is determined Advantages include higher accuracies and reduced health, safety, and environmental risks.
摘要翻译：提供了深度和径向取向检测的方法和系统。用于确定一个或多个井下部件的深度或径向取向的方法包括提供目标质量和使用检测装置以检测目标物质的深度和/或取向的步骤。在一些情况下，目标质量最初是非放射性的，然后在井下安装目标物质之后，可以将其照射以形成相对短暂的放射性靶物质，然后可以用辐射检测器检测。以这种方式，目标质量作为深度或径向取向标记。在目标质量位于与另一个井下部件的已知径向关系中的井下的情况下，一旦确定目标质量体的径向取向，就可以推导出另一个井下部件的径向定位。优点包括更高的精度和减少的健康，安全性和环境风险

摘要： This invention relates to a downhole hydraulic pump for hydrocarbon wells that is installed and operated using coiled tubing. The downhole hydraulic pump is driven by a hydraulic power system positioned at the surface and connected through a closed loop system using multiple channels of the coiled tubing. The coiled tubing is formed of a combination of channels including strength component such as steel and having one channel that is at least lined with a non-metallic corrosion resistant surface where clean hydraulic fluid is carried from the hydraulic power system to the downhole hydraulic pump through the non-metallic corrosion resistant channel so to be less likely to pick up manufacturing and environmental particulates and corrosion by-products within the channel carrying the hydraulic fluid to the downhole hydraulic pump. The non-metallic corrosion resistant lined channel may comprise plastic pipe.

摘要： This invention relates to a process for isolating one or more segments of a gravel packed well from other segments to treat the isolated segments and easily re-establish flow from the other segments after the treatment. The treatment includes techniques for enhancing or permanently blocking production from the isolated segment. The process includes the installation of a removable plug and a permeability poison that forms a fluid seal to prevent longitudinal fluid flow along the annular production space outside the tubular production pipe. With wireline or other low-cost wellbore workover systems, access is re-engaged with the secluded formation including removal of plugs and fluid seals within the tubular production pipe. The inventive process allows enhanced recovery of fluids by focusing treatments on problem areas without harming productive segments of the well.

摘要： A whipstock adapted for insertion into a wellbore through a tubing string having a smaller diameter than the wellbore casing or the open hole portion of the wellbore includes a setting mechanism comprising extendable legs which engage the wellbore wall to bias the whipstock into a position of inclination of the whipstock guide surface relative to the wellbore axis. The setting mechanism includes an actuating rod which may be actuated by a conventional downhole tool setting device to extend and retain the legs in their extended position. Cooperating ratchet means and tensionable couplings on the setting mechanism including a frangible coupling part permit actuation of the whipstock to its set position and retrieval of the setting device. The whipstock is releasable from the setting device by an adaptor having cooperating ball keys engageable with an adaptor actuating shaft and the upper end of the whipstock body.

摘要： An anti-surge/reverse thrusting tool for reducing the forces on a drill bit used in subterranean well drilling operations along with methods for drilling wells using a drill string employing the tool. The tool utilizes the pressure differential between drilling fluid flowing through the tool and the fluid located in the well bore annulus proximate the tool to reduce the likelihood of drill bit stall. The tool generally comprises an outer housing and a piston assembly that is axially shiftable relative to the housing.
