  • Method and system for detecting and addressing a kick while drilling
    Patent number: 10851645
    Abstract: Systems, devices, and methods for detecting and addressing a kick on a drilling rig are provided. A controller on the drilling rig may receive measurements from one or more sensor systems on the drilling rig and determine a severity index value corresponding to the likelihood of a kick. If the severity index level is determined to reach a specified threshold, an operator may be prompted to perform a flow check and/or activate a blow-out preventer.
    Type: Grant
    Filed: May 12, 2017
    Date of Patent: December 1, 2020
    Assignee: NABORS DRILLING TECHNOLOGIES USA, INC.
    Inventors: Chakrapani Mandava, Andrew Armstrong, Michael Lockridge

  • EFFICIENCY TRACKING SYSTEM FOR A DRILLING RIG
    Publication number: 20170300845
    Abstract: Systems, devices, and methods for tracking the efficiency of a drilling rig are provided. A sensor system on a drilling rig is provided. A controller in communication with the sensor system may be operable to generate measureable parameters relating to at least one Key Performance Indicators (KPIs). The measurable parameters may be compared with measureable parameters from a target to generate an Invisible Lost Time (ILT) period and an Invisible Saved Time (IST) period for the drilling rig. The KPIs, ILT period, and IST period may be displayed to a user.
