Abstract: Embodiments of the present invention generally provide an apparatus, method, and system for operating an electric downhole tool on a non-conductive support line (slickline) by converting a battery voltage to an output voltage suitable for operating the tool. In response to receiving a trigger signal, the output voltage signal is applied to the tool. The tool is controlled by varying the output voltage signal according to a power control sequence. Accordingly, electric tools typically requiring surface intervention by an operator via an electric cable (wireline) may be operated on slickline.

Abstract: Anti-extrusion devices, packer elements, and inflatable packers include shape memory polymer (SMP) materials to enhance the operation of a packer, a bridge plug, or other downhole isolation tool. Seal system use seals of various material including SMP materials as booster for the seal produced. Tool for flow shut-off and sliding sleeve applications use SMP materials to open or close off flow through a tool.

Abstract: A neutron logging tool has multiple detectors spaced about the circumference of the tool. The detectors are shielded from each other such that each detector detects gamma rays from the area of the borehole and formation to which it is closest. The log readings from each detector can be associated with the orientation of that detector. The orientation-specific log readings can then be aggregated to form an azimuthal log which can be used to analyze pre-fractured and/or post-fractured formations. 2026164v1 -c N -

Abstract: The present invention generally relates to an apparatus and a method for conveying and operating tools into a wellbore. In one aspect, a method of performing a downhole operation in a wellbore is provided. The method includes pushing a continuous rod into the wellbore, wherein the continuous rod includes a member disposed therein. The method further includes positioning the continuous rod proximate at a predetermined location in the wellbore and performing the downhole operation. In yet another aspect, a system for performing a downhole operation in a wellbore is provided.

Abstract: Embodiments of the present invention generally provide a method, apparatus, and system for monitoring conditions in wellbore in real time prior to setting an inflatable element in the wellbore. The inflatable element is inflated with an inflation tool run on a cable with one or more electrically conductive wires (the cable is commonly referred to as a "wireline"). One or more sensors, internal or external to the inflation tool, are monitored before setting the inflatable element to verify well conditions are compatible with the inflatable element. The sensors may be internal or external to the inflation tool.

Abstract: Treatment fluid is introduced into an area of interest within a wellbore, by running a pack-off system into the wellbore, the pack-off system comprising an upper packing component and a lower packing component disposed on a tubular body; and positioning the pack-off system adjacent to the area of interest, which is between the upper and lower packing component. The introduction of treatment fluid into an area of interest within a wellbore comprises running a pack-off system into the wellbore, the pack-off system comprising an upper packing component and a lower packing component disposed on a tubular body; positioning the pack-off system adjacent to the area of interest, which is between the upper and lower packing component; expanding radially the upper and lower packing component; introducing the fluid into the pack-off system; and controlling a leak rate of the fluid through spaces between the packing components and the wellbore. An independent claim is also included for a pack-off system for increasing fluid pressure within an area of interest within a wellbore, comprising a tubular body; two spaced-apart, selectively settable packing components on the tubular body for sealing off the area of interest; and selectively actuable setting apparatus connected to the tubular body, for selectively setting the two spaced-apart selectively settable packing components.

Abstract: A continuous rod string 100 is fed into in a deviated wellbore 10 from delivery reel 35. Delivery apparatus 30 provides the insertion force. The delivery apparatus 30 also includes a depth encoder 25 to record the amount of string 100 within the wellbore 10 at any given time thereby determining the position of a tool 110 within the wellbore 10. Data measured and recorded by the downhole tool 110 is then correlated with the depth encoder reading thereby defining the position of the tool 110 in the wellbore 10. This information is then used to form a "log" of measured data as a function of depth within the wellbore 10 at which the data is recorded. A communication line 105, which may be electrical or fibre optic, transmits signals from or to a downhole apparatus 110 such as a logging device or pump.

Abstract: Methods and apparatus for detonating explosives or igniting flammables a re disclosed. According to some embodiments of the invention, initiators includ e an initiating component holding an exploding bridgewire (EBW) or an exploding foil initiator (EFI) and a flammable component housing thermite. An end of the flammable component mates with a corresponding end of the initiating component. A meth od of initiating the explosives or flammables includes connecting the two componen ts to assemble the initiator, disposing the initiator proximate the explosives or flammables, and activating the initiator to cause ignition of the thermite that then initiates the explosives or flammables. Additionally, a non-explosive kit for the initiato r includes the two components with the EBW or EFI initially spaced from the thermite within the flammable component to make the initiator disarmed until final assembly thereof. Cutting torches and perforating guns provide examples of downhole tools that benefit from aspects of the invention.
