The elements of the isolators can have internal gaps to allow for axial shifting after perforation that is thermally induced. The gaps assure remaining alignment with the new perforations despite some axial shifting. The bottom hole assembly can alternatively have an anchor to resist thermally induced forces that can cause axial shifting.

The travel stop can be a solid ring or segments and can have a rounded outer surface designed to engage the surrounding tubular in a flush relationship. Alternatively the outer surface can also have hardened particles for a bite into the wall of the surrounding tubular before the blunt portions of the travel stop come into contact with the inside wall of the surrounding tubular.

The cutting structure on the lower mill is arrayed in rows that are preferably parallel. The cutting structure in each row is made sharper and more durable than prior designs with the objective of cutting the window higher than where the window mill started the window. The use of the rows increases the contact stress of the inserts on the casing inside wall because at any given time fewer and sharper inserts are cutting the casing wall to lengthen the window. As a row wears down the next row takes over to continue the cutting where the previous row was active and to further penetrate the casing wall. The cutout angle can also increase as this occurs. As a result a decreased insert density results in more effective casing wall cutting to extend the window to allow larger tools to exit into the window off the whipstock.

The tubing string may include a testing device used to determine whether a specific fracture cluster within the horizontal wellbore should be re-fractured. Diverting material may be pumped down the tubing string and positioned adjacent a fracture cluster to hydraulically isolate the fracture cluster during the re-fracturing process. The diverting material may be cleaned out of the horizontal wellbore after all desired fracture clusters along the horizontal wellbore have been individually re-fractured.
A hydrophobic surface comprises a surface texture and a coating disposed on the surface texture, wherein the coating comprises an amorphous diamond like carbon material doped with 10 to 35 atomic percent of Si, O, F, or a combination comprising at least one of the foregoing, or a low surface energy material selected from fluoropolymer, silicone, ceramic, fluoropolymer composite, or a combination comprising at least one of the foregoing; and wherein the surface texture comprises a micro texture, a micro-nano texture, or a combination of a micro texture and a micro-nano texture.
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.
Two control systems are provided to run in parallel between a surface location and the final controlled element, in this case a subsurface safety valve. The primary control circuit is controlling until a predetermined signal is given to the secondary control line which has the effect of actuating the valve a single time against the force of a bias or a shear pin that breaks. The movement of a shuttle in the housing due to the predetermined signal being provided in the secondary line puts the secondary control system in the position of running the tool. The primary system is valved off and cannot return into service. There are just two lines into and out of the housing to make the valve operate at the desired location. A test port is provided for surface testing.
The method allows a pressure test of a string with external packers without having the packer setting apparatus exposed to tubing pressure so that at a later time and at a lower pressure than the pressure test pressure, the external packers can be set with annulus pressure opened to a piston that references a low pressure chamber. The packers can be set in any desired order. Thereafter, a circulation sub can be triggered to open to allow the tracking to start. Fracking each interval beyond the first in an uphole direction can be accomplished with pumping ever increasing balls to seats associated with sliding sleeves to open the sleeves in order. In cemented completions, after a pressure test, a ported sub can open on a timer or other signal to allow pumping a combination of a bridge plug and a perforating gun to the desired location.
A tubewire buckling mitigation assembly for use with injection of tubewire into coiled tubing. The mitigation assembly includes a passageway having a small diameter passage, an intermediate diameter section and first and second tapered transition sections.
E21B 23/14 - Apparatus for displacing, setting, locking, releasing or removing tools, packers or the like in boreholes or wells for displacing a cable or a cable-operated tool, e.g. for logging or perforating operations in deviated wells

COMPOSITION AND METHOD FOR TREATING SUBTERRANEAN FORMATIONS USING INORGANIC FIBERS IN INJECTED FLUIDS
A method of plugging an opening in a subterranean formation such as a fracture system is provided. A gel composition can be provided which includes an aqueous fluid, a cross-linkable polymer soluble in the aqueous fluid and a cross-linking agent. Inorganic fibers can be added to the gel composition. The gel composition can be injected into the opening in the subterranean formation. The gel composition can be cross-linked, and the opening can be plugged with the gel composition. In certain illustrative embodiments, the inorganic fibers can be mineral wool fibers.
A carbon composite contains expanded graphite; and at least one of a filler or a reinforcement; wherein the expanded graphite comprises a plurality of randomly oriented basal planes. Methods of making the carbon composite and articles comprising the carbon composite are also disclosed.
