Abstract: Various systems and methods are provided for accessing and traversing one or more complex data structures and generating a functional user interface that can enable non-technical users to quickly and dynamically generate detailed reports (including tables, charts, and/or the like) of complex data including time varying attributes and time-series data. The user interfaces are interactive such that a user may make selections, provide inputs, and/or manipulate outputs. In response to various user inputs, the system automatically calculates applicable time intervals, accesses and traverses complex data structures (including, for example, a mathematical graph having nodes and edges), calculates complex data based on the traversals and the calculated time intervals, displays the calculated complex data to the user, and/or enters the calculated complex data into the tables, charts, and/or the like. The user interfaces may be automatically updated based on a context selected by the user.

Abstract: An actuator for an orienting device for orienting a borehole apparatus in a borehole and an orienting device comprised of the actuator, wherein the orienting device is comprised of an orienting mechanism which is actuated by longitudinal movement. The actuator is comprised of a housing having a first end and a second end and a fluid passageway extending through the housing from the first end to the second end. Further, a longitudinally reciprocable piston, positioned within and providing a first partial obstruction of the fluid passageway, engages with the orienting mechanism such that longitudinal movement of the piston actuates the orienting mechanism.

Abstract: A pack-off bushing for placement inside an outer conduit while a fluid is passed through an inner conduit positioned within the outer conduit. The bushing includes a mandrel having a mandrel passage extending axially therethrough, a housing carried on the mandrel and capable of axial movement relative to the mandrel and a balancing system associated with the mandrel and the housing for applying a balancing force to the mandrel to oppose an axial mandrel force applied to the mandrel.

Abstract: A downhole drilling assembly including a housing having an upper end for connection to a drill string and a lower end, a fluid passage extending through the housing from the upper end to the lower end, a power unit contained within the housing, a drive assembly extending within the housing between the power unit and the lower end of the housing such that a mandrel chamber is defined between the drive assembly and the housing, a radially movable first stabilizer associated with the housing and located between the power unit and the lower end of the housing, an axially movable mandrel contained within the mandrel chamber, the mandrel being associated with a stabilizer actuator for causing radial movement of the first stabilizer in response to axial movement of the mandrel, and a sensor apparatus located between the power unit and the lower end of the housing for sensing at least one drilling parameter.

Abstract: A drilling assembly and a method for directional drilling using the drilling assembly. The drilling assembly comprises a drilling bit, a near bit stabilizer and an adjustable gauge stabilizer. The near bit stabilizer is located a first axial distance from a distal end of the drilling assembly and has a near bit stabilizer gauge which is greater than a nominal drilling assembly gauge. The adjustable gauge stabilizer is located a second axial distance from the distal end, which is greater than the first axial distance, and is adjustable between an extended and retracted gauge. The retracted gauge is less than the near bit stabilizer gauge. A bit drop angle is created between the drilling assembly and the drilling bit, while a stabilizer angle is created between the near bit stabilizer and the adjustable gauge stabilizer.

Abstract: An apparatus and method for directing a first and a second object into a primary and a secondary borehole respectively from a main borehole communicating therewith at a borehole junction. The apparatus includes a deflector for positioning at the borehole junction to direct the first and second objects into the primary and secondary boreholes. A retainer holds the objects relative to each other such that when the first object is aligned to be directed into the primary borehole, the second object is aligned to be directed into the secondary borehole. A retainer orienting mechanism orients the retainer relative to the borehole junction so that the objects are aligned to be directed into the boreholes. The method includes positioning the deflector at the borehole junction and inserting the objects and the retainer into the main borehole. The retainer is oriented relative to the borehole junction so that the objects are aligned to be directed into their respective boreholes.

Abstract: A single trip tool and method for cutting a subsurface window through a well casing and installing an anchoring and orienting sleeve in the casing adjacent the window for subsequent downhole well procedures and equipment installation. A mill held in position within the casing by a hydraulic and weight-set tubular anchor sleeve is used to cut multiple vertical slots in the casing wall to form a single, large window. An indexing mechanism controls circumferential placement of the mill to ensure contact between adjacent slots. The mill is supported for rotation and longitudinal movement by a carriage mount that advances along dual sloping rails causing the mill to form an increasingly deeper cut during its initial cutting movement. Following formation of the window, the mill is retrieved leaving the anchoring sleeve in place for subsequent well procedures. A second embodiment anchors and orients the cutting assembly with an internally contoured coupling that is part of the casing string.

Abstract: A diverting tool having a deflecting surface is equipped with an anchor that secures the tool at a desired subsurface location within the casing of a primary well bore to divert drilling equipment used to drill a lateral bore. An annular cup-type seal on the tool seals with the casing. A passage through the tool permits fluid bypass across the seal as the tool is lowered through the casing. The passage is closed from the well surface when the tool is anchored. After the lateral bore is drilled, the tool is used to divert a liner into the lateral bore. The upper end of the liner extends into the casing where it is centralized. The liner is cemented in the lateral bore and in the casing with the cement placed to effect sealing of the intersection of the liner and casing. A tubular mill removes the cement and liner from the casing above the diverter tool leaving a flush opening from the casing into the liner.

Abstract: A joint of tubular casing with a pre-formed window in its sidewall has a tubular sleeve fixedly attached to the interior of the tubular casing by a plurality of shearable set screws. The exterior surface of the sleeve is sealed to the interior surface of the tubular casing on opposing sides of the window. The window is filled with a fluid, and then the window is covered with one or more layers of a composite material such as fiberglass. In use, the joint of tubular casing is run down to the depth of interest in an earth borehole, and then the window is oriented with respect to the formation of interest at the depth. The joint of tubular casing is then cemented in place, after which the tubular sleeve is retrieved by the use of a fishing tool, causing the set screws to shear upon the upward movement of the fishing tool. After the interior sleeve is retrieved, a whipstock is lowered into the cased borehole, until it is oriented and anchored therein.
