a new chemical compound is developed at petroleum university of technology to enhance therecovery of the free imbibition process and simultaneously hinder asphaltene precipitation. thecompound is tested on heavy oil samples from marun oil field, bangestan reservoir. the effects ofthe chemical compound on viscosity, hydrocarbon composition, and average molecular weight ofthe heavy oil are invest...

in order to determine the physico-chemical characteristics of oils from upper sarvak and dariyan formations, 4 oil samples collected from reshadat and resalat oilfields were analyzed. physical properties of oils (e.g. the api gravity), indicates that dariyan oil in both resalat and reshadat oilfield is similar to (with low pour points and high sulfur contents) the oils from sarvak reservoir. ba...

In thin-layered reservoirs, drilling engineers face tough challenges—planning their drilling programs to follow the most productive reservoir layers while avoiding nearby water, gas or high-pressure zones. The rewards for a successful drilling strategy are clear—increased oil production and reduced water cut. In an oil field in the Persian Gulf, for example, oil production was increased four- t...

The petrophysical analysis of the early Eocene Sui Main Limestone (SML) has been conducted in Kharnhak-1 well for the prospect of the hydrocarbon exploration of the Khairpur-Jacobabad High, Middle Indus Basin, Pakistan. The petrophysical analysis of SML is carried out on the basis of well logs including gamma ray, spontaneous potential, resistivity, neutron, and density logs. These analyses lea...

Gas injection into carbonate formations is one of the most important activities to protect oil reserves that can guarantee a steady production. On-time injection of enough gas can result in the recovery of billions barrels of oil. In addition, it can preserve a huge amount of gas for the next generations. If the reservoir depth is shallow, or the reservoir fluid has a little amount of intermedi...

lithofacies identification can provide qualitative information about rocks. it can also explain rock textures which are importantcomponents for hydrocarbon reservoir description sarvak formation is an important reservoir which is being studied in the marun oilfield, in the dezful embayment (zagros basin). this study establishes quantitative relationships between digital well logs data androutin...

an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundw...
