Unconventional Gas: Through a lens

  • Drilling

    A single drilling rig 20-50 metres high is used to drill down to the target rock formation and then horizontally to multiple unconventional gas reservoirs.

  • Groundwater Protection

    To protect the groundwater aquifer, multiple layers of steel and cement casing line the wellbore and provide an impermeable barrier between the well and the water source. Verification of well bore integrity during all phases of operations is an important objective for safe and efficient production.

  • Hydraulic Fracturing

    Once drilling is complete (4-8 weeks), the drilling rig is removed and the hydraulic fracturing equipment is brought in.

  • Perforating

    A series of small holes are made in the production casing along the horizontal section of the wellbore to allow the fracturing fluid to create small fractures in the rock.

  • Fracturing Fluid

    A mixture of water, sand and a small amount of chemical additives is injected at high pressure into the wellbore.

  • Rock Stimulation

    The frack fluid creates a series of hairline fractures in the rock formation.

  • Proppant

    The fractures are held open by grains of sand that are mixed into the hydraulic fracturing fluid, allowing the natural gas to escape from the tight rock and flowback up through the well.

  • Production

    Once the fracturing process is complete, the equipment is moved off site and replaced by a production wellhead, a device to separate the water from the natural gas, and a water storage tank.

  • Transportation

    The gas is transported from the site to customers via pipeline.
