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。

摘要： Systems and methods for supplying a stimulant fluid to a subterranean formation, including apportioning a production liner assembly into a plurality of treatment zones and providing the stimulant fluid to at least an initial treatment zone of the plurality of treatment zones. Apportioning the production liner assembly into the plurality of treatment zones may include utilizing a longitudinal flow control device to fluidly isolate at least a first portion of the plurality of treatment zones from at least a second portion of the plurality of treatment zones and/or placing an outlet of a stimulant fluid supply device proximal a selected treatment zone. May include providing the stimulant fluid through one or more outflow control devices. The systems and methods also may include receiving a reservoir fluid through one or more inflow control devices.

摘要： An electro-acoustic system for downhole telemetry employs a series of communications nodes spaced along a string of casing within a wellbore. The nodes allow wireless communication between transceivers residing within the communications nodes and a receiver at the surface. The transceivers provide node-to-node communication of data indicating elastic waves generated as a result of the formation of subsurface fractures. The data is processed which generates a map of fracture geometry. A method of evaluating fracture geometry in a subsurface formation uses a plurality of data transmission nodes situated along the casing string which send signals to a receiver at the surface. The signals are analyzed which generates a subsurface map.

摘要： Wellbore flow-control assemblies define a flow-controlled fluid conduit that selectively conveys a fluid flow, including fluid outflow and fluid inflow, between a subterranean formation and a casing conduit. The wellbore flow-control assemblies include a sacrificial flow-control device that defines a first portion of the flow-controlled fluid conduit and a directional flow-control device that defines a second portion of the flow-controlled fluid conduit. The sacrificial flow-control device resists the fluid flow prior to a flow-initiation event and permits the fluid flow subsequent to the flow-initiation event. The directional flow-control device permits one of fluid outflow and fluid inflow and resists the other.

摘要： An improvement to a centralizer that may reduce the torque required to rotate a casing in a borehole during primary cementing is disclosed. In a first embodiment, the improvement is adapted to a bow spring type centralizer having intermediate fixed and slidable sleeves with each sleeve circumscribed by an end band. The end bands are connected to each other by a plurality of bow springs. The improvement includes interposing a sleeve bearing between each end band and its respective intermediate sleeve. The sleeve bearings may be attached to the intermediate sleeves to permit their rotation with the casing relative to the stationary end bands and bow springs. Alternatively, the intermediate sleeves may be eliminated and the sleeve bearings interposed directly between the outer surface of the casing and inner surfaces of their respective end bands.
