  • Patent number: 11566470
    Abstract: An apparatus, a method for positioning a rock drilling, and a rock drilling rig is provided. The rock drilling rig includes a mobile drilling platform and a drilling mast connected to the drilling platform. The drilling platform is levelled vertically before initiating drilling. The apparatus determines the needed vertical levelling requirement. The levelling causes displacement of a drilling tool line passing through a drilling tool. The apparatus estimates the displacement and provides aid for the operator to position the drilling platform in order to compensate for the estimated displacement distance.

  • Patent number: 11560787
    Abstract: A stand-alone apparatus for determining the level (X) of liquid (F) in oil boreholes (P) overcomes the need of a pressurized gas source. A loudspeaker-type electroacoustical transducer (11) both emits characteristic acoustical signals through the mouth of the borehole and detects the return of an echo from the surface of the liquid downhole for clocking the time-interval between emission and return to determine the level of the liquid. To overcome the limited power inherent in a loudspeaker-type transducer relative to masking borehole acoustic noise, a method of operation correlates the intensity amplitude of the detected echo with the emitted signal. Another solution comprises repeating emission and detection cycles a number of n times and then adding or integrating the n curves into a resulting curve which is filtered. The detected liquid level may be used for determining the submergence and regulating the speed of a pump in the borehole.

  • Patent number: 11499421
    Abstract: A method of mud logging is disclosed which the chemical constituents and concentrations of formation fluid are calculated based on pulse power plasma parameters and the constituent species and concentrations of drilling mud, including reaction products, upon which the pulse power plasma has acted. Based on correlation between pulse power plasma parameters, including drilling parameters, drilling can be optimized for identified formation and formation fluid species. An offset between the chemical makeup of the drilling mud exposed to pules power plasma and the chemical makeup of formation fluid is calculated. Based on the calculated offset, pulse power plasma drilling can be controlled as a function of drilling mud concentration including in other wellbores in the formation or field.

  • Patent number: 11486204
    Abstract: A disconnect sub is connected at one end to a pipe for deployment into a well, where the disconnect sub is then connected to a downhole sealing device such as a plug. The disconnect sub comprises a disconnection point that has a lower tensile break value than the rest of the plug, and has a predetermined tensile break value such that the disconnection point will fail when a threshold value of axial tensile load is applied to the disconnect sub. This offers two methods of disconnection of the pipe from the plug after the plug has set—firstly, rotation of the pipe, or if rotation is not possible, overpull of the pipe in excess of the threshold will cause failure of the disconnection point and separation of the pipe from the plug.

  • Patent number: 11459860
    Abstract: A gas lift system may be installed within a well to allow gas lift operations where gas may be injected into the annular area of the well while producing fluids through the interior of the production tubular or upon demand may be reversed so that gas may be injected into the interior of the production tubular while producing fluids to the annular region of the well. In order to allow bidirectional production on demand two types of gas lift mandrels are installed as part of the production tubular. Both types of gas lift mandrels are configured such that gas lift valves are mounted to the exterior of the mandrels. In order to facilitate the desired direction of gas flow through the two types of gas lift mandrels a plug and packer system with or with out one way valves may be utilized to direct and contain the pressurized gas flow within the well.
