Glycolipids are amphiphilic molecules which bear an oligo- or polysaccharide as hydrophilic head group and hydrocarbon chains in varying numbers and lengths as hydrophobic part. They play an important role in life science as well as in material science. Their biological and physiological functions are quite diverse, ranging from mediators of cell-cell recognition processes, constituents of memb...

In shallow water the frequency domain controlled source electromagnetic method is subject to airwave saturation that strongly limits the sensitivity to resistive hydrocarbon targets at depth. It has been suggested that time-domain CSEM may offer an improved sensitivity and resolution of these deep targets in the presence of the airwave. In order to examine and test these claims, this work prese...

Langgu Depression is a mature oil and gas exploration area with complicated lithological physical properties. The varying formation fluid, low-resistivity hydrocarbon-bearing reservoirs, non-uniform logging series greatly increase the difficulty of reservoir identification. Monte Carlo method employed to simulate neutron–gamma responses saturation influential factors. According result, new iden...

lurestan province is petroliferous area. the reserved oil are in ilam and sarvak  (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate  source  rocks ar...

salman and resalat oilfields are such marine oilfields that are in vicinity of each other. there is resalat oilfield in distance about 80-90 kilometers from lavan island in persian gulf. this oilfield is located in 25 kilometer southwest in reshat oilfield. salman oilfield is located in vicinity of water border line of united arab emirate in 140 kilometers of south of lavan island. this oilfiel...

Abstract Otan-Ile field, located in the transition zone Niger Delta, is characterized by complex structural deformation and faulting which lead to high uncertainties of reservoir properties. These greatly affect exploration development thus require proper characterization. Reservoir characterization requires integration different data such as seismic well log data, are used develop model. There...

Low-salinity water flooding has become one of the major emerging enhanced oil recovery techniques where lower salinity is flooded into a hydrocarbon reservoir in order to increase recovery. It’s been widely reported that wettability alteration from oil-wet water-wet low-salinity process improves Many factors control system wettability, however, role and intensity each factor not completely unders...

Counter-current imbibition in one dimension is analyzed, in which a wetting phase (water) displaces a non-wetting phase against gravity. An approximate analytical approach is used to derive an expression for the saturation profile in the case where the mobility of the displaced phase at the inlet is finite. This approach is applicable to waterflooding in hydrocarbon reservoirs, flow in geotherm...

Time-lapse 3-D seismic monitoring of subsurface rock property changes incurred during reservoir fluid-flow processes is an emerging new diagnostic technology for optimizing hydrocarbon production. I discuss the physical theory relevant for three-phase fluid flow in a producing oil reservoir, and rock physics transformations of fluid-flow pressure, temperature and pore-fluid saturation values to...

Monoaromatic hydrocarbons such as benzene have been found in sludge created by oil production facilities and industries. Benzene is considered as a carcinogenic substrate and biodegradation, primarily under aerobic conditions, is an important environmental process for water and soil associated benzene remediation. Aerococcus sp. strain BPD-6 isolated from petroleum hydrocarbon contaminated oily...
