Combined petroleum system modeling and GCxGC to improve understanding of the crude oil chemistry in the Llanos Basin, Colombia

Important properties of a crude oil, such as viscosity, are determined by the crude oil's chemical constituents. In particular, viscosity is highly dependent on the asphaltene content. Various processes that act on reservoir crude oils can alter chemical c ...

Dynamic investigation of nutrient consumption and injection strategy in microbial enhanced oil recovery (MEOR) by means of large-scale experiments

Koen Blanckaert

Microbial enhanced oil recovery (MEOR) depends on the in situ microbial activity to release trapped oil in reservoirs. In practice, undesired consumption is a universal phenomenon but cannot be observed effectively in small-scale physical simulations due t ...

Simultaneous initiation and growth of multiple radial hydraulic fractures from a horizontal wellbore

Brice Tanguy Alphonse Lecampion

Multi-stage fracturing is the current preferred method of completion of horizontal wells in unconventional hydrocarbon reservoirs. Its core component consists in simultaneously initiating and propagating an array of hydraulic fractures. We develop a numeri ...

Hydraulic fracturing for unconventional resources development: challenges & opportunities for the mechanical community

Brice Tanguy Alphonse Lecampion

Oil and gas production from unconventional reservoirs (i.e. tight) now accounts for about half of the total US hydrocarbon production from essentially zero ten years ago. Such a drastic increase in production from unconventional resources was made possible ...

Thermal and capillary effects on the caprock mechanical stability at In Salah, Algeria

Victor Vilarrasa Riano

Thermo-mechanical effects are important in geologic carbon storage because CO2 will generally reach the storage formation colder than the rock, inducing thermal stresses. Capillary functions, i.e., retention and relative permeability curves, control the CO ...

An exergy based approach to determine production cost and CO2 allocation for petroleum derived fuels

The renewable and non-renewable exergy and CO2 costs of petroleum derived fuels produced in Brazil are evaluated using exergoeconomy to rationally distribute the exergy costs and the CO2 emitted in processes with more than one product. An iterative procedu ...

Resolving biodegradation patterns of persistent saturated hydrocarbons in weathered oil samples from the Deepwater Horizon disaster

Jeremy Samuel Arey, Jonas Gros

Biodegradation plays a major role in the natural attenuation of oil spills. However, limited information is available about biodegradation of different saturated hydrocarbon classes in surface environments, despite that oils are composed mostly of saturate ...

Advances in Structural Elucidation of Small Molecules via High Performance Mass Spectrometry

Konstantin Zhurov

Qualitative and quantitative analyte analysis is omnipresent: from quality control in food, pharmaceutical, biotechnology industries, to new molecular syntheses, detection of explosives and drugs, as well as natural compound mixture analysis, such as crude ...

Ultrathin Shell Double Emulsion Templated Giant Unilamellar Lipid Vesicles with Controlled Microdomain Formation

Esther Amstad

A microfluidic approach is reported for the high-throughput, continuous production of giant unilamellar vesicles (GUVs) using water-in-oil-in-water double emulsion drops as templates. Importantly, these emulsion drops have ultrathin shells; this minimizes ...

First day of an oil spill on the open sea: Early mass transfers of hydrocarbons to air and water

Jeremy Samuel Arey, Jonas Gros, Deedar Nabi

During the first hours after release of petroleum at sea, crude oil hydrocarbons partition rapidly into air and water. However limited information is available about very early evaporation and dissolution processes. We report on the composition of the oil ...
