An electric motor-actuated tractor (e-Tractor) apparatus and method for use in downhole operations. The apparatus includes a power subassembly, a tractor subassembly and one or more gripper subassemblies and can be: run in a single or multiple e-Tractor configuration; run in either intermittent-motion tractoring mode or continuous-motion tractoring mode with the ability to switch between the two modes; used to generate both distal and proximal longitudinal forces to move the run-in string into or out of the wellbore; repeatedly activated and deactivated without run-in string manipulation or hydraulic pressure; and combined with tensiometer and other sensor package options to provide real-time data to the surface to optimize tractoring operations. The apparatus and method are well-suited for application in an c-coil conveyed workover or completion system, and for use in extended reach laterals in horizontal wells.

An electric motor-actuated packer and/or anchor (EMAP/A) apparatus and method for use in downhole operations. The apparatus includes a packer subassembly and/or a slip subassembly and can be: set in a packer and anchor mode; set in an anchor-only mode without energizing the packer elements; repeatedly set and unset without run-in string manipulation; run in a multiple, or redundant, configuration within a given tool string, with each EMAP/A apparatus capable of being set/unset independently of the others; and combined within a tool string in a straddle packer configuration, with inverted and non-inverted EMAP/As providing the ability to isolate an interval of interest from both above and below the interval. Among other uses, the apparatus and method are well suited for application in a single-trip, e-coil conveyed completion system, and particularly one providing for radial hydraulic jetting.

Electrically-actuated resettable downhole anchor and/or packer, and method of setting, releasing, and resetting

A ported casing collar. The ported casing collar comprises a tubular body defining an outer sleeve. At least first and second portals are placed along the outer sleeve. The casing collar also comprises an inner sleeve. The inner sleeve defines a cylindrical body rotatably residing within the outer sleeve. The inner sleeve contains a plurality of inner portals. A control slot is provided along an outer diameter of the inner sleeve. In addition, a pair of torque pins are provided, configured to ride along the control slot in order to place selected inner portals of the inner sleeve with the first and second portals of the outer sleeve. Preferably, the setting tool is a whipstock configured to receive a jetting hose and connected jetting nozzle. A method of accessing a rock matrix in a subsurface formation is also provided.

Ported casing collar for downhole operations, and method for accessing a formation

A method for avoiding a frac hit with an offset parent wellbore during a formation stimulation operation. The method includes providing a child wellbore within a hydrocarbon-producing field. The method also includes forming lateral boreholes off of a horizontal leg of the child wellbore at a first casing exit location. The method also includes conducting a formation stimulation operation at the first casing exit location through the lateral boreholes, as a first stage. The method additionally includes monitoring field data in a hydrocarbon-producing field associated with the child wellbore during the formation stimulation operation. The method then includes forming lateral boreholes off of the horizontal leg at a second casing exit location longitudinally offset from the first casing exit location along the horizontal leg. An orientation of the lateral boreholes at the second casing exit location relative to the horizontal leg is determined based on the field data.

Method of avoiding frac hits during formation stimulation

In an assembly for lowering and expanding a tubular element in a borehole on an expansion string, at least part of the weight of the tubular element is transmitted to the expansion string via an internal upset and a support protruding from an outer surface of the expansion string below the internal upset.

Assembly and method for creating an expanded tubular element in a borehole

A method for forming lateral boreholes from an existing parent wellbore is provided. The wellbore has been completed with a string of production casing. The method generally comprises providing a downhole tool assembly having a whipstock. The method also includes running the assembly down into the parent wellbore. A force is applied to the assembly to cause the whipstock to rotate within the wellbore into an operating position. In this position, a curved face of the whipstock forms a bend-radius substantially across the inner diameter of the casing. A jetting hose is run into the wellbore. Upon contact with the curved face of the whipstock, the jetting hose is re-directed through a window in the production casing. Hydraulic fluid is injected under pressure through the hose to provide hydraulic jetting. The hose is directed through the window and into the formation to create a lateral borehole extending many feet outwardly into a subsurface formation. A method of testing a subsurface formation for the presence of hydrocarbon fluids is also provided herein.

Method of testing a subsurface formation for the presence of hydrocarbon fluids

A method for underdisplacing fracture proppant in a well bore. The method can include providing a set retainer having a passage configured to receive a wiper plug. The method may also include installing the set retainer in the well bore and injecting a proppant-laden fluid into the well bore, through the passage of the set retainer and through a perforation to create the fracture. The method may include providing a wiper plug configured to be received in the passage of the set retainer. The method may also include inserting the wiper plug into the well bore and allowing the wiper plug to wipe a portion of the proppant-laden fluid past the set retainer and into the fracture. Additionally, the method may include allowing the set retainer to receive the wiper plug.

A downhole tool assembly for forming lateral boreholes from a parent wellbore is also provided herein. The assembly utilizes substantially the entire inner diameter of the casing as the bend radius for a hydraulic jetting hose.

Downhole hydraulic jetting assembly, and method for stimulating a production wellbore

A running tool includes subassemblies which release the running tool from the liner hanger in response to application of alternating tensile and compressive forces after application of left-hand torque. A running tool includes subassemblies which set the liner hanger in response to left-hand torque followed by increased pressure, and in response to increased pressure without prior left-hand torque being applied. A running tool includes threaded connections, without torque transmitted through the running tool being transmitted by the threaded connections. A method of setting a liner hanger includes applying a compressive force to the running tool; then applying left-hand torque to the running tool; and then applying a tensile force to the running tool. A method of releasing a liner hanger includes applying left-hand torque to the running tool; and then releasing the running tool from the liner hanger by applying a tensile force to the running tool.

Protective sleeve for threaded connections for expandable liner hanger

An apparatus for radially expanding and plastically deforming a tubular member. In some embodiments, the apparatus includes a tubular support, sliding sleeve, rupture disc, and expansion cone. The tubular support has a first internal passage, wherein the sliding sleeve is disposed, and a flow passage, wherein the rupture disc is seated. The sliding sleeve has a second internal passage and is moveable by fluid pressure between first and second positions. In the first position, the second internal passage is fluidicly coupled with a first annulus surrounding the tubular support. In the second position, the second internal passage is fluidicly isolated from the first annulus. The rupture disc fluidicly isolates the first internal passage from a second annulus surrounding the tubular support and is adapted to rupture, whereby the first internal passage and the second annulus are fluidicly coupled. The expansion cone is disposed in the second annulus and moveable under pressure from fluid in the second annulus.
