This chapter emphasizes the fundamentals of understanding coal as a source rock and reservoir rock and reviews many of the key issues that confront researchers and industry. Although this chapter emphasizes coal, many of the ideas and approaches it discusses can also be applied to dispersed organic matter in siliciclastic and carbonate rocks

The Coal Oil Point seep field (COP) in the Santa Barbara Channel offshore from Goleta, California, is a marine petroleum seep area of about three square kilometres, within the Offshore South Ell Oil Field and stretching from the coastline southward more than three kilometers (1.9 mi). Major seeps are located in water depths from 20 to 80 meters. The seep field is among the largest and best

Coalbed methane (CBM or coal-bed methane), coalbed gas, coal seam gas (CSG), or coal-mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries. The term refers to methane adsorbed into the solid matrix of the coal. It is called 'sweet gas' because of its lack of

Burial of coal also generates natural gas (principally methane) and no oil. The methane generated from coal may become stored in fractures in the coal seam as coal bed methane, which is a hazard in underground coal mining, but can also be exploited economically.

Coal forms on land in massive peat bogs that eventually get buried by the sea and other sediments are laid on top of them after millions of years, the peat turns into coal Oil and gas are derived from algae and other organisms living and dying in the

Reservoir Oil is a hydrocarbon fluid which has been accumulated over a long period of time in a porous, permeable and sedimentary rock. The most common reservoir rocks are sandstone and limestone. Fractured granite also contains hydrocarbons even though it is not a sedimentary rock. A typical oil reservoir contains oil, gas and water. Gas being the lightest occupies the upper part, oil

On top of what has already been explained, a major difference between an oil reservoir and a fuel tank is the flow rate of filling or extraction: it takes millions of years (or more !) to fill an oil reservoir, and to empty it partially men will take several decades to a century. All the elements above explain that, when a new oil field is

Oil and gas are formed from organic material mainly deposited as sediments on the seabed and then broken down and transformed over millions of years. If there is a suitable combination of source rock, reservoir rock, cap rock and a trap in an area, recoverable oil

Oil or petroleum is a readily combustable fossil fuel that is composed mainly of carbon and hydrogen, and is thus known as a hydrocarbon. The formation of oil takes a significant amount of time with oil beginning to form millions of years ago. 70% of oil deposits existing today were formed in the Mesozoic age (252 to 66 million years ago), 20% were formed in the Cenozoic age (65 million years

Unlike conventional reservoirs, coal seams are the source, trap, and reservoir for coalbed methane (CBM). A comparison of the two reservoir types shows profound differences in reservoir properties, storage mechanisms, flow mechanisms, and production profiles. Understanding the reservoir differences is key to successful evaluation and operation

After the oil is created, it is pushed by pressure upwards. Under the pressure from the oil the shale rock (which is a typical source rock) can form cracks and allow the oil to flow either upwards or in horizontal directions. The rocks that can both store and transmit the oil are the reservoir rocks. [1] Good reservoir rocks have high porosity

Coal was first discovered across Pakistan and the rest of South Asia in the 1880s and was used by the British-owned railway companies under colonial rule.Later, post-colonial Pakistan had used coal to fuel its industry from independence to the discovery of the Baluchistan's Sui gas field in 1952 and the Toot oilfield in 1964.
