Natural gases can be categorized on the basis of their phase diagram and the prevailing reservoir condition into four categories: 1. . The need for reliable estimates of gross rock volume and original hydrocarbons in place, which are important for. 02. . • Metamorphic rocks – Both igneous and sedimentary rocks. There are five geological requirements for the formation of a conventional hydrocarbon reservoir: Source Rock; Migration Path; Cap Rock; Reservoir Rock; Trap; These geological requirements are illustrated in Figure 2.

Jul 14, 2012 · The Seal • The seal or cap rock is an impermeable rock which don’t allow the hydrocarbons to escape from the reservoir rock.

The rock structure surrounding the reservoir has to be looked at carefully: Synclinally folded rocks dip towards the reservoir, reducing possible leakage but increasing their liability to slip into the reservoir.

That is: V b = V p + V g.

Anticlines increase leakage but are less prone to slip.

Reservoir rocks are complex structures, often comprising a variety of mineral types. Examples of reservoir rocks includes: Sandstones Limestone and /or Carbonate rocks. class=" fc-smoke">Oct 15, 2014 · 1344 Views Download Presentation. Oil and gas fields are geological features that result from the coincident occurrence of four types of geologic features (Figure 1): (1) oil and gas source rocks, (2) reservoir rocks, (3) seals, and (4) traps. The impervious rock covering the reservoir rocks is called a cap rock.

Petroleum reservoirs may contain any of the three fluid phases—water (brine), oil, or gas.

The bulk volume, V b, can also be defined as the sum of the volumes of the two constituents of the rock, pore volume and Grain Volume, V g. Petroleum reservoirs are broadly classified as oil or gas reservoirs. .
