摘要： A bridge plug arrangement includes a plug having an upper end and a bottom end. The bridge plug arrangement also optionally includes a cylindrical seat. The bridge plug arrangement further includes a tubular member. The tubular member may be part of a casing string. The tubular member is configured to receive the plug and, when used, the seat. The plug and/or the seat may be fabricated from a frangible material. A method for diverting fluids in a wellbore using the bridge plug arrangement is also provided. The method may include landing the plug onto the seat within the wellbore below a subsurface zone of interest. Treatment fluids are then injected into the wellbore, where they are diverted through perforations and into a formation. The plug and/or seat is then optionally broken into a plurality of pieces through use of a downward mechanical force.

摘要： Drill bits are provided. The drill bits are of the fixed-cutter, rotary-type. The drill bits have a plurality of blades having cutting elements disposed therealong. Junk slots are formed between the respective blades. A knife opening is formed in at least two of the junk slots. Preferably, the knife openings are disposed substantially transverse to a longitudinal axis of the drill bit. The drill bit also has one or more ribbon cutters. The ribbon cutters cyclically protrude through knife openings in the junk slots in order to facilitate the fragmentation of cuttings ribbons moving through the junk slots during a drilling operation.

摘要： Methods for installing tubulars (for example, conduits, casing or liners) into a highly deviated wellbore are disclosed. In a first embodiment, the method comprises a) drilling the well to the planned total depth of the interval, b) placing a first fluid into the wellbore below a prescribed measured depth in the high-angle portion of the wellbore, said first fluid having a density that causes the portion of the tubular that extends into the first fluid to become substantially neutrally buoyant, c) placing a second fluid into the wellbore above the prescribed measured depth, said second fluid having a density less than said first fluid, d) plugging the distal portion of the tubular with a lower plug (or check valve) and an upper plug, e) as the tubular is run into the wellbore, placing a lightweight fluid into the plugged section of tubular and a heavy fluid above the plugged section of tubular, and f) running the tubular into the wellbore to the planned total depth.

摘要： A method of managing lost returns in a wellbore includes contacting a filter cake with a treating fluid to remove metallic weighting agents from the filter cake, wherein the filter cake is disposed on a face of a formation fracture in the wellbore. The method also includes contacting the filter cake with a proppant slurry, wherein the proppant slurry contacts the filter cake concurrently with the treating fluid or after the treating fluid contacts the filter cake. This method may include increasing the filter cake permeability and may utilize a barite removal agent, such as a chelation agent. At least one related wellbore management method creates a fracture in the wellbore and props open the fracture to increase wellbore integrity to utilize higher weight drilling fluids and prevent fractures from forming further down the wellbore.
摘要翻译：管理井眼中的丢失回报的方法包括使滤饼与处理流体接触以从滤饼中除去金属加重剂，其中滤饼设置在井眼中的地层断层的表面上。该方法还包括使滤饼与支撑剂浆料接触，其中支撑剂浆料与处理流体同时接触滤饼，或处理流体接触滤饼之后。该方法可以包括增加滤饼渗透性，并且可以使用重晶石去除剂，例如螯合剂。至少有一个相关的井筒管理方法在井眼中产生断裂，并且支撑开放裂缝，以增加井眼完整性，以利用更高重量的钻井液，并防止裂缝进一步向下进入井身。
