Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

Rigorous characterizations of fluid contents, rock/fluid interactions, and pore-size
distributions are crucial in the development of unconventional resources. As a nonintrusive …

Flow assurance is essential to a sustainable oil and gas production system; if not managed
appropriately, it may cause huge CapEx/OpEx and is also a life-threatening phenomenon …

Completions are the conduit between hydrocarbon reservoirs and surface facilities. They are
a fundamental part of any hydrocarbon field development project. The have to be designed …

Abstract Among the Enhanced Oil Recovery (EOR) methods, gas-based EOR methods are
very popular all over the world. The gas injection has a high ability to increase microscopic …

Carbon dioxide miscible flooding has become a popular method for Enhanced Oil Recovery
(EOR) because it not only efficiently enhances oil recovery but also considerably reduces …

The emissions of CO2 have been recognized as the main cause of climate change. As an
important strategy being used to reduce the CO2 concentration in the atmosphere, carbon …

Application of enhanced oil recovery methods in Kazakhstan has been ongoing for decades
alongside the continued discovery of new oil and gas fields in the Pre-Caspian Basin. The …

In this paper, oil recovery and permeability reduction of a tight sandstone reservoir in
immiscible and miscible CO2 flooding processes are experimentally studied. First, a series …

The permeability reduction associated with asphaltene precipitation and deposition in gas
injection EOR processes has been widely observed and well-studied in conventional plays …
