  Interpretation of Subsurface Hydrocarbon Shows; Tim T. Schowalter and Paul D. Hess; Search and Discovery Article ...
Hydrocarbon residues are the result of bonding of hydrocarbons to solid mineral surfaces and/or the degradation of oil to an immobile viscous crude (e.g., by aerobic bacteria) or a burned-out carbonaceous residue.
Hydrocarbons in kerogen indicate only that liquid oil or gas is potentially available to the system in the form of a hydrocarbon source rock, but indicate nothing about the release migration or the entrapment of liquid-producible oil or gas.
Based on saturation of pore space, the only way to positively identify a type I continuous phase show would be to determine from cuttings, cores, or logs that the rock in question had a hydrocarbon saturation in excess of 35% for a sandstone reservoir or 55% for a carbonate reservoir.

Alkanes are a subcategory of hydrocarbons where each carbon is bonded to either another carbon or a hydrogen by single bonds.
Saturated hydrocarbons have the maximum number of hydrogen atoms, that value is 2n + 2 (n = number of carbons).
Since all saturated hydrocarbons are alkanes, this is also an alkane.

Sands saturated with conductive fluids, such as saline water or landfill leachates, have a relatively high conductivity.
Less pore fluid is required to fully saturate the pore space of a low porosity (dense) soil, resulting in lower soil electrical conductivity.
Pore water pressure response is primarily controlled by the degree of saturation, potentiometric surface, compressibility and horizontal permeability of the penetrated soil (Reference 4).

Although the Martin-Hou equation has been used for halogenated hydrocarbons (3), difficulties in its use have been encountered (2, 4), probably because this equation was not originally intended for use in the compressed liquid region at low reduced temperatures.
For most of the fluids studied, the optimal value of the pseudo acentric factor is virtually independent of the temperature range of the vapor pressure data and is within the range of values of acentric factors reported in the literature (6, 7) and values obtained using estimation methods (6).
Evaluation of the capability of the GMBWR equation for predictions of the saturated thermodynamic properties of halogenated hydrocarbons was performed by comparing predicted and reported property values at the predicted vapor pressure at tabulated saturation temperatures.

 Rule A-3. Unsaturated Compounds and Univalent Radicals (ACYCLIC HYDROCARBONS)
3.1 - Unsaturated unbranched acyclic hydrocarbons having one double bond are named by replacing the ending "-ane" of the name of the corresponding saturated hydrocarbon with the ending "-ene".
When, in cyclic compounds or their substitution products, the locants of a double bond differ by unity, only the lower locant is cited in the name; when they differ by more than unity, one locant is placed in parentheses after the other (see Rules A-31.3 and A-31.4).
If there are two or more chains competing for selection as the chain with the maximum number of unsaturated bonds, then the choice goes to (1) that one with the greatest number of carbon atoms; (2) the number of carbon atoms being equal, that one containing the maximum number of double bonds.
