How Oil Drilling Works
In 2008 alone, the United States produced an estimated 4.9 million barrels of crude oil per day and imported 9.8 million barrels per day from other countries [source: U.S. Energy Information Administration]. This oil gets refined into gasoline, kerosene, heating oil and other products. To keep up with our consumption, oil companies must constantly look for new sources of petroleum, as well as improve the production of existing wells.
How does a company go about finding oil and pumping it from the ground?
  • Expensive art, science, and luck
  • Drilling does not equal production
  • Very technical and regulated process
How Oil Drilling Works
  • Identify where the oil is.
  • Rent yourself a rig.
  • Drill a hole
  • Run casing & cement
  • Run your completion
Our Innovative Technologies:
Building Information Modeling - BIM
  • Identifying a target and Protoytye development & Modular design strategy
  • Design the directional path to reach the target.
  • Select tools and services required and CAD-Computer aided design and modelling
  • Design a complete program to drill to target and CAE-computer aided engineering and modelling
  • Identifying an objective & target and Where should you drill it?
  • Install a completion to achieve the wells objective and Validation and optimisation
  • Design a directional path to reach the target.
  • Select tools and services required.
    • Drilling Rig
    • Drillstring
    • Fluid System
    • Casing
    • Cement
    • Completion
  • Design & Execution of the Drilling Program
    • Drill Surface Hole
    • Run Surface Casing
    • Cement Surface Casing
    • Drill Next Hole Section
  • Drillstring: The Bit and Motor
    • Bit: Cuts or crushes rock
    • Motor (simple: Orients the bit in the desired direction
    • Rotary Steerable (smooth):Orients the bit in the desired direction while
    • continuously rotating
  • Drillstring: MWD/LWD
    • Measurement While Drilling
      • Pressure, temperature, & wellbore position in 3D
      • Downhole GPS
    • Logging While Drilling
      • Provides real-time information on formation characteristics.
      • Allows us to determine where the bit is relative to the formation we are drilling.
      • Helps define well placement and predict drilling hazards
    • Drilling Mud
      • Drilling fluid, known as mud, has several different functions essential to drilling an oil or gas well, including
        • Subsurface pressure control
        • Cuttings removal and transport to the surface
        • Suspend solids
        • Helps suspends weight of the drillstring and casing
        • Lubrication & cooling of the drillstring & bit
        • Wellbore stability
        • Transmit hydraulic energy to downhole tools
    • Casing
      • Protect freshwater formations
      • Isolate formations with significantly different pressure gradients
      • Isolate unstable formations or zones of lost returns
    • Cement
      • Protects & seals the wellbore
        • Isolate fluids from moving between formations
        • Isolate unstable formations
        • Plug off unwanted wellbore
    • Cutting Edge Technology We Use
      • Logging tools
        • Formation pressure sampling.
        • Perpendicular cores from the borehole.
      • Real time down-hole data streaming
        • Formation data streamed anywhere in the world.
      • Managed pressure drilling
        • High tech pressure control
      • Radio Frequency ID downhole tools
        • Digital chip tool activation.
      • Survey management
        • Crustal Anomalies
        • Gravitational field shifts
        • Solar flares
    • Costs
