摘要： A method and apparatus for running a whipstock into a well bore attached to a combination mill and drill bit, releasing the mill/bit from the whipstock, milling a window in the casing, and drilling a lateral well bore, all in one trip. The mill/bit is provided with a primary cutting structure better suited for milling through the casing, and a secondary cutting structure, better suited for drilling through the earth formation. The secondary cutting structure is initially smaller in diameter than the primary cutting structure. The whipstock can be attached to the mill/bit with a shear bolt supported by a boss on the whipstock, with the boss designed to arrest axial motion of the mill/bit after shearing of the bolt.

摘要： The disclosed embodiments allow a user to request new product designs and design changes remotely. The requested design or change is then submitted to a network-based automated process. The process may be remotely accessed by the user through a network connection. In one embodiment, the user may meet directly with a customer, pull up the specifications for the product in question, select a design or change desired by the customer, and submit the design or change. The process works in the background to validate the requested design according to one or more validation rules and/or best practices, and completes many of the necessary tasks to allow the requested design to proceed to manufacturing. Once the process has successfully completed the requested change, a notification is sent to the user containing information about the new or changed product, such as the new part number, order number, and the like.
摘要翻译：所公开的实施例允许用户远程请求新产品设计和设计变更。然后将所请求的设计或更改提交到基于网络的自动化过程。该过程可以由用户通过网络连接远程访问。在一个实施例中，用户可以直接与客户会面，提取相关产品的规格，选择顾客所需的设计或变更，并提交设计或更改。该过程在后台根据一个或多个验证规则和/或最佳实践来验证所请求的设计，并完成许多必要的任务以允许所请求的设计进行制造。一旦该过程已成功完成所请求的改变，则向用户发送包含关于新的或已更改的产品的信息的通知，诸如新的部件号，订单号等。

摘要： A method and liner assembly for drilling into unstable or depleted formations is provided that maintains control of the wellbore against caving such as where unconsolidated formations are penetrated and/or minimizes fluid losses such as to underpressured formations where differential pressures exist. The method and liner assembly herein includes the provision of a liner having a portion thereof that is drillable so that after setting of the liner, drilling can continue deeper into the unstable formations with minimal damage to the bit used to drill out the liner drillable portion. In one form, the liner has a shoe that includes cutter mounting blades, each having a set of cutters thereon. Relief slots are formed in the blades between cutters so that as the shoe and its blades are being drilled, the drill bit will cut through the slots, releasing the shoe cutters for transport up to the surface by the drilling fluid thereby minimizing damaging contact of the bit with the shoe cutters. Preferably, the shoe has a bi-center and anti-whirl design. In another form, the liner has preassembled therewith a whipstock and a pre-formed window of drillable material adjacent the whipstock, so that after drilling into the unstable formation with the liner assembly and setting it therein, subsequent drilling beyond the liner occurs by running a drill bit downhole and drilling until it engages the whipstock that guides it to the window for drilling therethrough.

摘要： A superabrasive cutter-equipped rotary drag bit especially suitable for directional drilling in subterranean formations is provided. The bit may employ PDC cutters in an engineered cutter placement profile exhibiting optimal aggressiveness in relation to where the cutters are positioned along the profile of the bit extending from a cone region laterally, or radially, outward toward a gage region therefore. The engineered cutter placement profile may include cutters exhibiting differing degrees of aggressiveness positioned in order to maximize rate-of-penetration and minimize torque-on-bit while maintaining side cutting capability and steerability.
