摘要： Non-aqueous carrier fluids containing nano-sized particles in high concentration are effective for zone isolation and flow control in water shutoff applications for subterranean formations. The nanoparticles interact with water and solidify it to inhibit its flow, but do not have the same effect on hydrocarbons and thus selectively assist the production of hydrocarbons while suppressing water. Suitable nanoparticles include alkaline earth metal oxides, alkaline earth metal hydroxides, alkali metal oxides, alkali metal hydroxides, transition metal oxides, transition metal hydroxides, post-transition metal oxides, post-transition metal hydroxides, piezoelectric crystals, and/or pyroelectric crystals.

摘要： In one embodiment telescoping members are extended to bridge an annular gap either before or after it is cemented. Some of the telescoping members have screens and others have flow passages that can be selectively opened with associated valves to frac an interval in any order desired. The valves are then closed after the frac job and the other telescoping members are made to allow screened flow from the fractured formation. In another embodiment an interval to be gravel packed and fractured has a series of screens and selectively opened valves on a bottom hole assembly such as a liner. One or more external packers are provided. The entire interval is gravel packed at one time followed by packer actuation and then selective opening of ports to conduct a fracture operation in any of the zones defined by the set packers and in any desired order.

摘要： This invention provides a method for controlling production operations using fiber optic devices. An optical fiber carrying fiber-optic sensors is deployed downhole to provide information about downhole conditions. Parameters related to the chemicals being used for surface treatments are measured in real time and on-line, and these measured parameters are used to control the dosage of chemicals into the surface treatment system. The information is also used to control downhole devices that may be a packer, choke, sliding sleeve, perforating device, flow control valve, completion device, an anchor or any other device. Provision is also made for control of secondary recovery operations online using the downhole sensors to monitor the reservoir conditions. The present invention also provides a method of generating motive power in a wellbore utilizing optical energy. This can be done directly or indirectly, e.g., by first producing electrical energy that is then converted to another form of energy.

摘要： The present invention provides a method for obtaining equalized production from deviated wellbores. A plurality of spaced apart flow control device are deployed along the length of the wellbore. The fluid from various zones are drawn in a manner that depletes the reservoir uniformly along the entire length of the wellbore. Each flow control device is initially set at a rate determined from initial reservoir simulations or models. The depletion rate, water, oil and gas content, pressure, temperature and other desired parameters are determined over a time period. This data is utilized to update the initial reservoir model, which in turn is utilized to adjust the flow rate from one or more zones so as to equalize the flow rate from the reservoir. The present invention also provides a flow control device which includes an outer shroud that reduces the effect of fluid impact on the flow control device and one or more tortuous paths which carry the formation fluid into the production tubing. A control unit controls the flow output from the flow control device. The control unit may communicate with surface equipment or act autonomously to take actions downhole based on programmed instructions provided to the control unit.

摘要： A fluid system has been discovered using a distribution of graded calcium carbonate particle sizes, a biopolymer and a polymerized starch. The biopolymer is a non-ionic polysaccharide of the scleroglucan type. It is important that the calcium carbonate particles be distributed across a wide size range to effectively prevent filtration or fluid loss into the formation. Since the filter cake particles do not invade the well bore due to the action of the biopolymer and starch, no high pressure spike occurs during the removal of the filter cake. This high pressure spike indicates damage to the formation and well bore surface, which damage typically reduces overall permeability of the formation. The rheological properties of the fluid allow it to be used in a number of applications where protection of the original permeable formation is desirable. The applications include, but are not limited to, drilling fracturing and controlling fluid losses during completion operations, such as gravel packing or well bore workovers.

摘要： A gravel pack well tool for use in a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone and then the well tool having a auger-liner assembly is lowered and rotated into the preset gravel. The liner assembly is comprised of a fluid-permeable linear surrounded by a torque sleeve which transmits torque from a workstring to a nose sub at the leading edge of the liner assembly. The nose sub has a fish-tail bit thereon to assist the downward movement of the liner assembly into the preset gravel and has passages therein for fluid flow therethrough in the event the assembly becomes stuck in the gravel during installation.

摘要： A fluid system has been discovered using graded calcium carbonate particle sizes and a modified lignosulfonate. Optionally, a thixotropic polymer such as a welan or xanthum gum polymer is used to keep the CaCO.sub.3 and lignosulfonate in suspension. It is important that the calcium carbonate particles be distributed across a wide size range to effectively prevent filtration or fluid loss into the formation. Further, the lignosulfonate must be polymerized to an extent effective to reduce its water solubility. The modified lignosulfonate (lignin sulfonate) is necessary for the formation of a filter cake essentially on the surface of the well bore. Since the filter cake particles do not invade the well bore due to the action of the modified lignosulfonate, no high pressure spike occurs during the removal of the filter cake which indicates damage to the formation and well bore surface and typically reduces overall permeability of the formation. The rheological properties of the fluid allow it to be used in a number of applications where protection of the original permeable formation is desirable. The applications include, but are not limited to, drilling, fracturing and controlling fluid losses during completion operations, such as gravel packing or well bore workovers.
摘要翻译： 已经发现使用分级碳酸钙粒度和改性木质素磺酸盐的流体系统。 任选地，使用触变性聚合物如威兰或黄原胶聚合物以保持CaCO 3和木质素磺酸盐悬浮。 重要的是碳酸钙颗粒分布在宽的尺寸范围内以有效地防止过滤或液体流入地层。 此外，木素磺酸盐必须以有效降低其水溶性的程度进行聚合。 修饰的木质素磺酸盐（木质素磺酸盐）基本上在孔的表面上形成滤饼是必要的。 由于滤饼颗粒由于改性木质素磺酸盐的作用而不会侵入井眼，因此在除去滤饼之前不会发生高压尖峰，这表示对地层和井眼表面的损害，并且通常降低地层的总渗透率 。 流体的流变性能允许其用于需要保护原始可渗透地层的许多应用中。 这些应用包括但不限于在完井操作期间的钻孔，压裂和控制流体损失，例如砾石填充或井眼工作。

摘要： A tubular for reservoir fines control includes a body having an outer surface and an inner surface defining a flow path. A plurality of openings are formed in the body connecting the outer surface and the flow path. A material mesh is overlaid onto the outer surface. The material mesh is formed from a material swellable upon exposure to a selected fluid. The material mesh has a selected porosity allowing methane to pass into the flow path while preventing passage of fines.
