Abstract:

Expulsion of hydrocarbons from a shale source rock can be divided in four stages. In the first stage, only a small amount of hydrocarbons can be expelled in water solution and by diffusion. Compaction and hydrocarbon concentration gradient are the major driving forces, whereas their corresponding hydrocarbon expulsion amounts make up 30% and 70% to the total, respectively. In the second stage, in addition to transport by water solution and by diffusion, source rocks expel a large quantity of gas in free phase. In the third stage, the most important feature is that source rocks expel oil as a s

Abstract:

Water inflow to petroleum wells hampers production of oil or gas leading to early shut downs of the wells without sufficient recovery of hydrocarbons in place. Downhole water sink (DWS) is a completion/production technique for producing water-free hydrocarbons with minimum amount of water from reservoirs with bottom water drive and strong tendency to water coning. DWS eliminates water invasion to hydrocarbon production by employing hydrodynamic mechanism of coning control in situ at the oil-water or gas-water contact. The mechanism is based upon a localized water drainage generated by another

Abstract The Zhangjiatan shale of the Southeastern Ordos Basin, which deposits in deep lake facies, has strong lithologic heterogeneity; it represents as shale, sandy laminae shale and thin sandstone. Shale with mm- to cm-scale sandy laminae is defined as Sandy Laminae Shale (SLS). However, the relationship between lithologic heterogeneity and hydrocarbon accumulation has never been studied. This study shows that lithologic heterogeneity, especially the occurrence of SLS will influence the accumulation of hydrocarbons within the shale system.

Marine surveys for the detection of naturally seeping hydrocarbons require a wide range of complementary remote sensing and geochemical techniques in order to achieve reliable data interpretation and prediction.

Activities by coastal States in relation to the exploration and exploitation of non-living natural resources (namely hydrocarbons and deep-sea minerals) on the continental shelf beyond 200 nautical miles (M) from their territorial sea baselines are reviewed. Geological conditions dictate such that hydrocarbons are likely to occur where there are thick accumulations of sediments (at least 2-3 km is needed for organic matter to generate significant amounts of hydrocarbons), whereas deep-sea minerals are found on or beneath the seabed of the deep oceans, which are generally “starved” of sediment.

Abstract:

Today the Arctic region exploration is one of the most important courses for research in our country because large amounts of unexplored oil and gas deposits are located there. Large deposits of hydrocarbons are situated in water areas of the North seas. Gas explosions complicate the development of hydrocarbon deposits in these water areas. They occur as a result of an accidant opening and further spread of gas. It is impossible to carry out the frequent exploration of the area with gas layers, then the numerical modelling of the area with already detected gas deposits is conducted. In this wo

Hydrocarbon reservoir zone located on Low Resistivity is a typical and hidden oil and gas layer which always wrong in assessing as a water layer due to the complex geological origin and resistivity log limitation in identifying hydrocarbon. Presence of shale in a reservoir will decreasing resistivity value and increasing saturation value, so it can cause the results of the analysis to be pessimistic in the identification of hydrocarbons. In that case need to do analysis to core data on research area in order to know the cause of Low Resistivity on reservoir zone that having a probability of hy

Abstract. The Amon mud volcano (MV), located at 1250 m water depth on the Nile deep-sea fan, is known for its active emission of methane and non-methane hydrocarbons into the hydrosphere. Previous investigations showed a low efficiency of hydrocarbon-degrading anaerobic microbial communities inhabiting the Amon MV center in the presence of sulfate and hydrocarbons in the seeping subsurface fluids. By comparing spatial and temporal patterns of in situ biogeochemical fluxes, temperature gradients, pore water composition, and microbial activities over 3 yr, we investigated why the activity of ana

Abstract:

AbstractNon-hydrocarbon gas species (CO2, N2, H2) are locally important in exploration for gas, and there is a growing body of evidence that acid water originating in shales materially affects the diagenesis of nearby sandstones. These gases have been studied by analysing the products of closed-vessel hydrous pyrolysis of known petroleum source rocks, and comparing the results with field observations. Alteration of petroleum source rocks at temperatures >250°C yields a significant amount of non-hydrocarbon components. Ethanoate and higher acid anions are liberated in substantial quantities;

Abstract:

A fundamental aspect of prospect evaluation is whether the trap volume or the charge volume limits the volume of trapped hydrocarbons. Traps filled to a leak point are full traps, although I rarely describe them as such. I commonly say “full to spill” but rarely do I hear “full to a leak point.” Why not? A summary of literature from fault leakage, seeps, field studies, and theoretical source-yield calculations illustrates the implication that source overcharge (i.e., the charge exceeding the trap volume) occurs in basins that vary widely in age and tectonic setting. Perhaps surprisingly, this

Abstract This paper presents a three-dimensional, three-phase compositional model for simulating CO2 flooding including CO2 solubility in water. Both fully implicit and IMPES formulations are included. In this model, CO2 is allowed to dissolve in the aqueous phase while all other components except water exist in the oil and gas phases. Oil- and gas-phase densities and fugacities are modeled by a cubic equation of state. The aqueous phase properties are functions of the amount of dissolved CO2. CO2 solubility is computed using a CO2 fugacity coefficient table that is converted internally from i

Since the discovery of giant hydrocarbon fields in the north of Western Siberia, no unified concept regarding the mechanism and stages of their formation has been developed. This paper on the example of the Urengoy field demonstrates that the formation of HC accumulations from Jurassic to Cenomanian is related to hydrocarbon fluids, flowing upwards from the deep depth, and their subsequent transformation. In the sedimentation process, the gases of the secondary kerogen destruction form an upward fluid flow, which dissolves oil components from source rocks and carry them to shallower depths. Th

ABSTRACTHydrocarbon migration mechanism into a reservoir is one of the most controversial in oil and gas geology. The research aimed to study the effect of supercritical carbon dioxide (СО2) on the permeability of sedimentary rocks (carbonates, argillite, oil shale), which was assessed by the yield of chloroform extracts and gas permeability (carbonate, argillite) before and after the treatment of rocks with supercritical СО2. An increase in the permeability of dense potentially oil-source rocks has been noted, which is explained by the dissolution of carbonates to bicarbonates due to the high

The presence of water, i.e., connate or hydraulic fracturing water, along with the gaseous hydrocarbons in shale nanopores is largely overlooked by previous studies. In this work, a new unified real gas-transport model has been developed for both organic and inorganic porous media accounting for the nanoconfined water film flow. More specifically, a gas core flows in the center of the organic/inorganic pore surrounded by a water film which can be further divided into an interfacial region (near-wall water) and bulk region (bulk water).
