FAQ:

1. What is drill casing?

Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream.

2. What is hole hammer?
Pneumatic down-the-hole (DTH) hammer is a pneumatic drilling tool using compressed air as a power source. It is suitable for drilling in pebble, gravel, and hard rock strata. It is often used in building pile foundation construction, bridge, mining, geological exploration, hydrological wells, and other fields.

3. What is overburden fill?

Overburden Soil is a general, unprocessed, fill material that can contain a variety of different materials, depending on where it is sourced. Overburden Soil can contain sand, rocks, clay and stones, and will typically lack the organic material and nutrients found in topsoil.

4. Why is overburden important?

In a petroleum system, the overburden rock overlies the source rock and contributes to its thermal maturation because of higher temperatures at greater depths. The age and thickness of the overburden rock determines the burial rate and thereby influences the heating rat.

5. How far can you directional bore?
What are the minimum and maximum lengths of crossing? Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for heavy rig horizontal directional drilling is 3,000 m
