摘要： A milling assembly for use in milling away an object in a wellbore. A milling bottom hole assembly is run in on a Telecoil® running string and includes a rechargeable power section which is recharged via tube-wire in the running string. The milling bottom hole assembly also includes a sensor section which measures tension, compression and torque experienced by the running string during milling.

摘要： A re-fracturing method involves placement and centralization of a liner string that has shaped charges at predetermined locations that are externally isolated with packers. The shaped charges can be set off in a desired order and re-fracturing can then take place in new locations. In a bottom up order for perforating sequentially larger balls can be landed on seats and developed pressure or component movement generated by applying pressure can be used to set a shaped charge and isolate portions of the borehole below. The balls and even the seats can be later milled out or just allowed to disintegrate or dissolve with well fluids that are present or later added to clear the liner for subsequent production. Alternatively, the liner could be removed by release of the packers before production or injection begins.

摘要： A matrix acidizing monitoring system wherein a sensor array is operably associated with a matrix acidizing bottom hole assembly and contains first and second sets of sensors that detect a matrix acidizing operational parameter at different times at one or more particular locations along the wellbore. This allows the effectiveness of the acidizing to be modeled.

摘要： A method of increasing a roughness of coiled tubing injector blocks that includes providing a pair of gripper blocks each having a gripper surface configured to grip coiled tubing within an injector head and increasing a first roughness on the gripping surfaces to a second roughness. A coating may be applied to the gripping surfaces to increase the roughness. The coating may be chromium carbide, molybdenum boride, iron boride, titanium boride, or a transitional metal boride. The gripping surfaces may be treated to increase the roughness to a second roughness. The gripping surfaces may be blasted by abrasives or shot peened to increase the roughness. The second roughness may be greater than 20 μm. A system to inject coiled tubing into a wellbore may include an injector head, coiled tubing, and at least two gripper blocks having a gripping surface with a roughness of at least 20 μm.

摘要翻译： 重新压裂的方法涉及将衬垫柱放置和集中，该衬套线束在预先定位的位置上形成电荷，这些位置是用封隔器进行外部隔离的。 成形的装料可以按期望的顺序排出，然后可以在新的位置进行再压裂。 按顺序排列顺序较大的球可以落在座椅上并产生压力，或通过施加压力产生的部件运动可用于设定成形装料并隔离下方的钻孔部分。 球甚至座椅可以随后被磨碎，或者仅仅被允许与存在或稍后添加的井液分解或溶解以清除衬里以供后续生产。 或者，可以在生产或注射开始之前通过释放封隔器来移除衬里。
