Utilizing their technologies, expertise in reservoir rock analysis, and equipment from Carl Zeiss, Ingrain will characterize thousands of meters of whole core currently being stored at ANH s National Core Repository ( Litoteca Nacional de Colombia ).

The decades in development of drilling technology for conventional and unconventional oil and gas production has not only improved access to natural gas in low-permeability reservoir rocks, but also posed significant adverse impacts on environmental and public health.
33.
The working tools of the reservoir engineer are subsurface geology, applied mathematics, and the basic laws of physics and chemistry governing the behavior of liquid and vapor phases of crude oil, natural gas, and water in reservoir rock.
34.
Until the 1970s, most oil wells were vertical, although reservoir rocks which contain hydrocarbons are usually horizontal or nearly horizontal; a horizontal wellbore placed in a production zone has more surface area in the production zone than a vertical well, resulting in a higher production rate.
35.
This property is often called " Net reservoir rock " . In the oil and gas industry, another quantity " Net Pay " is computed which is the thickness of rock that can deliver hydrocarbons to the well bore at a profitable rate.

Over time, the Persian Gulf basin area has experienced continuous deposition that was consistent through the Paleozoic era and led to the initial accumulation of the carbonate rocks ( which are excellent reservoir rocks ) and evaporites ( which play a big role as hydrocarbon seal rocks ).
37.
Petroleum geology and geophysics focus on provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behavior of oil, water and gas within porous rock at very high pressure.
38.
In addition to the aquatic environment, which is usually a sea, but might also be a river, lake, coral reef or algal mat, the formation of an oil or gas reservoir also requires a sedimentary basin that passes through four steps : deep burial under sand and mud, pressure cooking, hydrocarbon migration from the source to the reservoir rock, and trapping by impermeable rock.

PZ-LK = Paleozoic to lower Cretaceous Nubia ( reservoir rock ); UK-EO = Upper Cretaceous to Eocene pre-rift carbonate ( source rock ); N, R, K, and B = syn-and post-rift Nukhul, Rudeis, Kareem and Belayim formation ( sources, reservoirs, seals and overburden ); SG = South Gharib salt ( seal and overburden ); Z = Zeit ( seals and overburden ); and PP = Plio-Pleistocene ( overburden)
