摘要： Methods for installing tubulars into a highly deviated wellbore may include 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, c) placing a second fluid into the wellbore above the prescribed measured depth, d) plugging the distal port ion of the tubular with a lower plug 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. The first fluid has a density that causes the portion of the tubular that extends into the first fluid to become substantially neutrally buoyant, and the second fluid has a density less than the first fluid.

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： A process for drilling a well or a portion of a well capable of providing a generally constant interior wall diameter (monobore) and does not require installation of any liner or steel casing. The process comprises circulating settable material into the borehole wherein the settable material sets on at least a portion of the interior wall of the borehole to create a liner along the wall of the borehole and removing excess settable material out of the borehole.

摘要： The present invention is a method for improving well cementing. A fluid such as drilling mud or preflush fluid is oscillated in the annulus prior to introduction of cement slurry into the annular interval to be cemented. The fluid is oscillated by changing its direction of flow at least twice. The oscillatory flow of the fluid flushes gelled drilling mud and filter cake from the annulus more effectively than conventional unidirectional flow. Following the oscillatory phase, cement slurry is pumped into the annular interval to be cemented, thus displacing the fluid, and is allowed to set. The fluid can be oscillated in the annulus either before or after the cement slurry is introduced into the casing. A selective check valve is also described which permits all fluids to flow in the forward direction out of the casing and into the annulus and which permits all fluids other than cement slurry to flow in the reverse direction out of the annulus and into the casing.
摘要翻译：本发明是提高固井效果的方法。在将水泥浆引入待凝结的环形间隔之前，诸如钻井泥浆或预冲洗流体的流体在环形空间中振荡。通过将流体的方向改变至少两次来振荡流体。流体的振荡流动比常规的单向流动更有效地从环空中冲洗凝胶钻井泥浆和滤饼。在振荡阶段之后，将水泥浆泵入环形区段以进行胶结，从而使流体移动，并允许其固化。在将水泥浆引入壳体之前或之后，流体可在环形空间中摆动。还描述了选择性止回阀，其允许所有流体沿向前方向流出壳体并进入环形空间，并且允许除水泥浆之外的所有流体沿相反方向流出环空并进入壳体。
