Coal and CSG – 012
So, what is coal? When organic matter is laid down in a swamp and covered over it decomposes without oxygen (anaerobic) to form coal. Depending on the dominant type of organic matter, different macerals of coal will form (inertinite, exinite, … Read More
Oil and Gas Drilling – 011
So how do we find oil and gas ? First, lets stick to conventional sandstone (coarse grained) sediments and dry gas. These are perhaps the simplest after water wells. Water Wells Oil and gas drilling used the technology available from … Read More
Sedimentary Geology Part 2 -010
So far we have looked at how a Sedimentary Basin forms in a mid continent setting (intra cratonic). These basins have continental sediments, from a nearby provenance (mountain range) and are often coal and gas prone. Australia typically has plenty of … Read More
Geology Sedimentary Processes – 007
The earth is a spheroid (nearly a sphere) about 12700 km in diameter, depending on exactly where you measure it (there is an equatorial bulge and various bumps). Most of the planet is molten, although the central part is predicted … Read More
