A method for measuring the equilibrium GOR (gas-oil ratio) of reservoir fluids using microfluidic technology is developed. Live crude oils (crude oil with dissolved gas) are injected into a long serpentine microchannel at reservoir pressure. The fluid forms a segmented flow as it travels through the channel. Gas and liquid phases are produced from the exit port of the channel that is maintained...

Marine controlled-source electromagnetic (MCSEM) technology has been successfully established as an effective tool for offshore hydrocarbon (HC) exploration. In this paper we consider another application of the MCSEM method for HC reservoir monitoring. We demonstrate that EM methods can also be used for the monitoring of producing wells in connection with the enhanced recovery of hydrocarbons. ...

Optimum implementation of non-conventional wells allows us to increase considerably hydrocarbon recovery. By considering the high drilling cost and the potential improvement in well productivity, well placement decision is an important issue in field development. Considering complex reservoir geology and high reservoir heterogeneities, stochastic optimization methods are the most suitable appro...

Core has traditionally played a key role in the characterisation of conventional and unconventional hydrocarbon reservoirs, from exploration to mature production, because it provides only means observe make measurements on actual reservoir rock. However, recent oil-industry downturns have driven many question value routinely taking core, given associated costs […]

the conventional phase behavior study of petroleum reservoir fluids are valid when the reservoir temperature is far enough from the critical condition in which the material balance equation can be applied correctly. when the temperature of the reservoir is in the vicinity of the critical temperature the classical methods can’t determine the phase behavior of the mixture due to rapid phase chang...

The hydrocarbon-bearing formation of Miano gas field belongs to the Early Cretaceous and it is bounded by two shale intervals, which are considered as maximum flooding surfaces (MFS). interval includes reservoir units: a tight its overlying conventional reservoir. Core samples, borehole logs, well production performance revealed that reservoirs present reversed trends in quality through without...

Abstract Environmental problems associated with depleted oil and gas reservoirs upon long-term production from them are likely to become important challenges in future decades. With the increasing trend of hydrocarbon reservoirs, more across world reaching second half their life—a fact that places an emphasis on necessity investigating what is known as reservoir subsidence. Different analytical...
