   In addition two coal drilling programs by the NSW Department of Industry, designed to help define the limits of the basin, have resulted in wide-spaced drilling coverage over most of the basin. Petroleum exploration within the basin has been minimal, consisting of a small number of geophysical surveys and two stratigraphic wells.

4. Well drilling - Wikipedia

   en.wikipedia.org/wiki/Well_drilling

   Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

6. Drill bit (well) - Wikipedia

   en.wikipedia.org/wiki/Drill_bit_(well)

   Regardless of type, drill bits must satisfy two primary design goals: maximize the rate of penetration (ROP) of the formation and provide a long service life. The reason for this is a direct consequence of the rotary drilling method. Modern oilfield drilling operations require substantial capital and operating expense.

7. Petroleum geology - Wikipedia

   en.wikipedia.org/wiki/Petroleum_geology

   This is usually done by drilling more appraisal wells around the initial exploration well. Production tests may also give insight in reservoir pressures and connectivity. Geochemical and petrophysical analysis gives information on the type ( viscosity , chemistry, API, carbon content, etc.) of the hydrocarbon and the nature of the reservoir ...

8. Directional drilling - Wikipedia

   en.wikipedia.org/wiki/Directional_drilling

   Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore ...

   Provide a means of casing suspension (Casing is the permanently installed pipe used to line the well hole for pressure containment and collapse prevention during the drilling phase). Provides a means of tubing suspension (Tubing is removable pipe installed in the well through which well fluids pass).
