Alaska holds more than 68 billion barrels of proved oil reserves and 36.7 trillion cubic feet natural gas with some special conditions such as proximity to permafrost, making Alaskan petroleum unique. The low temperature in shallow reservoirs prohibited hydrocarbons’ ideal maturation, thereby generating several heavy viscous accumulations this state. This also limits the enhanced recovery (EOR)...

Abstract Oil and gas recovery may cause formation damage during drilling, completion, production phases. As a result of fundamental chemical, thermal, mechanical, biological interactions, can occur due to impairment permeability porosity, causing undesirable operational economic problem. The fluid-rock interactions resulting from oilfield chemicals injection enhanced oil (EOR) such as chemical ...

Abstract Chemical enhanced oil recovery (EOR) processes are usually used as additives for hydrocarbon production due to its simplicity and relatively reasonable additional costs. Polymer flooding uses polymer solutions increase by decreasing the water/oil mobility ratio increasing viscosity of displacing water. The commonly synthetic water-soluble in EOR application is partially hydrolyzed poly...

Abstract With the growing demand for energy supply and natural decline of oil reservoirs, development new enhanced recovery (EOR) techniques become more critical. Polymer flooding EOR is one most successful chemical methods but suffers many drawbacks at high temperatures salinity (HT‐HS) conditions. Superparamagnetic nanoparticles (NPs) have been recently investigated subsurface applications, i...

Low-salinity water flooding (LSWF) is environment-friendly and operates similarly to conventional waterflooding without the need for synthetic chemical materials. The application of LSWF makes sense in Vietnam as HC production has steadily declined since 2002, majority main oil fields have become near mature fields. In next years, Enhanced Oil Recovery (EOR) should be a top priority Petro boost...

Many world class large carbonate reservoirs leave behind at least half of the initial oil in place. Typically water injection is used to improve oil recovery while gas injection is used to maintain pressure or to promote oil gravity drainage. Immiscible gas injection, including injection of CO2, has been considered but not implemented on a large scale for economic reasons. Furthermore, interest...

The application of nanoparticles for enhanced oil recovery (EOR) has been shown to be advantageous over conventional methods. Wettability alteration reservoir rock from oil-wet water-wet is one the main factors in improving matured reservoirs. sandstone reservoirs are generally negatively charged, and hence, a proper selection surface charge important. In this work, novel nanofluid prepared usi...

Enhanced oil recovery (EOR) implementation at field scale is complex. Therefore, pilot applications are usually conducted before execution. This paper introduces a project successfully applied for the Lower Miocene, Bach Ho field. Topics covered include: (i) area selection, (ii) chemical preparation, (iii) specification and design execution, (iv) implementation, (v) observation interpretation, ...

Nanotechnology is the modern way of developing products, which results high efficiency nanomaterial’s use in hydrocarbon recovery processes. Due to unique physico-chemical properties nonmaterial have lead their application field petroleum processing industries, such as exploration, reservoir characterization, drilling, cementing, production and stimulation, enhanced oil (EOR), refining processi...
