Offshore Drilling

Conducted in ocean or sea environments to tap into underwater oil and gas reserves.

  • Fixed platforms: Permanent structures attached to the ocean floor.
  • Floating platforms: These platforms can be moved and are often used in deeper waters.
  • Subsea production systems: These operations occur directly on the seabed to access hydrocarbons.

Hydraulic Fracturing (Fracking)

This method involves injecting high-pressure fluid into rocks to create fractures, allowing oil or gas to flow more easily out of the rock formations.

Enhanced Oil Recovery (EOR)

Techniques to extract more oil from old wells where conventional methods aren’t enough.

  • Thermal EOR: Involves injecting steam to heat the oil, making it easier to pump out.
  • Gas EOR: Uses gases like CO2 to push more oil out of the reservoir.
  • Chemical EOR: Involves injecting chemicals that reduce surface tension, helping the oil flow more freely.


Quarrying focuses on extracting stone and aggregates from the Earth used primarily in construction.

  • Dimension stone extraction: Extracting large blocks of stone for construction or sculpture.
  • Aggregate extraction: Gathering materials like gravel, sand, and crushed stone used in building roads and making concrete.

Renewable Resource Extraction

This method involves gathering resources that can regenerate over time, making it more sustainable.

  • Biomass harvest: Collecting organic material like wood and agricultural waste to produce energy.
  • Geothermal extraction: Tapping into the Earth’s internal heat to generate electricity or provide heating solutions.
