Jun 1, 2011 · ABSTRACT. Estimation of residual hydrocarbon saturation remains an outstanding challenge in formation evaluation and core analysis. Standard interpretation methods for nuclear-resistivity logs cannot distinguish between mobile and residual hydrocarbon saturation. In extreme cases, fluid pump out or production testing are the only options to ascertain whether the reservoir's in-situ hydrocarbon ...

The vertical tensor component represents a series resistivity relationship where vertical Rt is the weighted sum of the sand and shale resistivities, Combining both vertical and horizontal tensor components yields a system of coupled, nonlinear equations that provide a more robust solution for hydrocarbon saturation than a scalar model.A saturated hydrocarbon compound contains only C-C single bonds and all the carbons are fully used in this.

The general formula for saturated hydrocarbons is C n H 2n+2 (assuming non-cyclic structures). Saturated hydrocarbons are the basis of petroleum fuels and are found as either linear or ...Hydrocarbon saturation is a vital petrophysical parameter in play evaluation and reserve estimation. However, it is difficult to calculate hydrocarbon saturation in unconventional shale plays due to variabilities in lithology, high clay content, presence of organic matter and pyrite, low porosity and complex wettability [7], [8].The saturation of water in an oil or gas reservoir at discovery is called the connate water saturation, or S wc. The connate water saturation and the irreducible water saturation can differ. ... wettability …Characterization of aged hydrocarbon-contaminated sites is often a challenge due to the heterogeneity of subsurface conditions. Geoelectrical methods can aid in the characterization of such sites due to their non-invasive nature, but need to be supported by geochemical and microbiological data. A saturated hydrocarbon is a hydrocarbon that is made of single carbon-carbon bonds. Such hydrocarbons are characterized by having the maximum number of H atoms per C atom.

Saturated hydrocarbons are called paraffins, a name derived from the Latin parum affinis, which means slight affinity. Paraffins or alkanes are trace constituents of biological lipids, but alkanes are the most stable and abundant hydrocarbon constituents of terrestrial rocks. Unsaturated hydrocarbons are commonly referred to as olefins because ethylene, a …Hydrocarbons with only carbon-to-carbon single bonds (C–C) and existing as a continuous chain of carbon atoms also bonded to hydrogen atoms are called alkanes (or saturated hydrocarbons). Saturated , in this case, means that each carbon atom is bonded to four other atoms (hydrogen or carbon)—the most possible; there are no …Knowledge of initial fluids saturation has great importance in hydrocarbon reservoir analysis and modelling. Distribution of initial water saturation (Swi) in 3D models dictates the original oil in place (STOIIP), which consequently influences reserve estimation and dynamic modelling. Calculation of initial water saturation in heterogeneous carbonate reservoirs always is a challenging task ...Saturated hydrocarbon has long chains as well as branched ones and further classified as aliphatic hydrocarbons and cycloalkanes. Some examples are methane, ethane, propane and butane. 2. Unsaturated Hydrocarbons. In organic compounds unsaturation is due to the presence of double and triple bonds.Fig. 3.34 shows how the capillary number is linked to residual hydrocarbon saturation. Note that x-axis is in the log scale. This trend means that N c has to be increased several orders of magnitude before any impact on residual oil saturation is invoked. However, for basement reservoirs, residual saturation bears a different meaning.The general formula for saturated hydrocarbons is C n H 2n +2 (assuming non-cyclic structures) as shown in hexane (C 6 H 14) below. Cycloalkanes are hydrocarbons containing one or more carbon rings to which hydrogen atoms are attached. The general formula for a cyclic hydrocarbon containing one ring is C n H 2n as shown in cyclohexane (C 6 H 12 ...Jan 1, 2015 · Water and Hydrocarbon Saturation. The fifth step in a log analysis is to find water saturation. Water saturation is the ratio of water volume to pore volume. Water bound to the shale is not included, so shale corrections must be performed if shale is present. We calculate water saturation from the effective porosity and the resistivity log.

Types As defined by the International Union of Pure and Applied Chemistry 's nomenclature of organic chemistry, hydrocarbons are classified as follows: Saturated hydrocarbons, which are the simplest of the hydrocarbon types. They are composed entirely of single bonds and are saturated with hydrogen.

The saturation exponent usually is fixed to values close to 2. The saturation exponent models the dependency on the presence of non-conductive fluid (hydrocarbons) in the pore-space, and is related to the wettability of the rock. Water-wet rocks will, for low water saturation values, maintain a continuous film along the pore walls making the rock …Alkanes are described as saturated hydrocarbons, while alkenes, alkynes, and aromatic hydrocarbons are said to be unsaturated. Aliphatic hydrocarbons Alkanes.

Dec 1, 2012 · Highlights The resistivity of hydrocarbon (HC) reservoirs is controlled by HC saturation. This in turn is controlled by reservoir and fluid properties. Results indicate that high-density oil and poor reservoir quality reduces HC saturation. Reservoir location in or near the oil–water transition zone reduces overall HC saturation. This in turn leads to lower resistivity and, thus, weaker CSEM ... An unsaturated solution contains less than the maximum soluble material, while a saturated solution contains all of the material that it is able to dissolve in its current state, with excess material remaining undissolved.The fatty acids may be saturated or unsaturated, depending on the presence or absence of double bonds in the hydrocarbon chain; a saturated fatty acid has the maximum number of hydrogen atoms bonded to carbon and, thus, only single bonds. In general, fats that are liquid at room temperature (e.g., canola oil) tend to be more unsaturated than fats that …Interpreting hydrocarbon shows.
