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

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
