Clay content in soil potentially has strong influence on soil structure and thereby controls soil physical, hydraulic, and gas transport properties. Only few studies have investigated the effect of clay content on saturated hydraulic conductivity…
In order to explore the changing law and influencing factors of the filtering performance of natural gas filter elements under high pressure conditions, four types of filter elements were selected as the research objects, and field tests and…
Prior to 2008, shale gas reservoirs were deemed uneconomical to produce. Hydraulic fracturing and horizontal drilling have shifted this perspective, reducing the flow resistance from the reservoir to the well. Notwithstanding the thousands of shale…
The direct conversion of crude oil to light olefins is considered one the cheapest and most reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries operated to produce mainly transportation fuels, such as gasoline and…
Herein, we present the production of jet and diesel range hydrocarbons from non-edible hexane-extracted Brassica carinata oil. The influence of four heterogeneous catalysts (two noble metal catalysts: Pd/C and Ru/C, and two transition metal…
Ten sandstone samples were chosen to conduct rock pore structure change law experiment before and after injection and production and the NMR fluid test experiment, the changes of pore size, permeability, and space filling degree were compared and…
The technology of methane storage by the adsorption-hydration hybrid (AHH) combines the adsorbed natural gas (ANG) and natural gas hydrate (NGH) methods to store gas in porous materials. This technology can overcome the shortcomings of ANG and NGH…
Gas shales contain a variety of clay-rich materials with multifarious pore networks. Clay-hosted porosity is an essential component and considered to play a crucial role in establishing the original hydrocarbon molecules in place and transport…
Porous silica materials offer wide range of possibilities for enhancement of the productivity of oil reservoirs. However the mechanism of adsorption of polar components of crude oil on silica surface is poorly understood that hinders technological…
CO2 injection contributes to formation energy supplement to remedy the fast production decline in tight oil reservoir and CO2 storage at the same time.CO2 Here, we report CO2-water relative permeability with consideration of acid-rock reaction. The…
Injection of supercritical CO2 (SCCO2) causes significant changes in the petrophysical properties of shales and affects the integrity of geological storage sites. The alteration of mineralogy and pore structure plays a major role in defining the…
Developing nanocarriers deliver molecules to targeted locations has received widespread attention in different fields ranging from biomedical to oil and gas industries. Mesoporous Silica Nanoparticles (MSNs), where the pore size diameter ranges from…
Injection of CO2 into shale reservoirs to enhance gas recovery and simultaneously sequester greenhouse gases is a potential contributor towards the carbon-neutral target. It offers a low-carbon, low-cost, low-waste and large-scale solution during the…
The direct conversion of crude oil to light olefins is considered one the cheapest and most reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries operated to produce mainly transportation fuels, such as gasoline and…
In this study, frontal chromatography experiments have been conducted with hydrocarbon gases (methane and ethane) on selected stationary phases (quartz, 3 Å, 5 Å and 13X molecular sieves, activated carbon, coal and shale) to study compositional and…
Studies on gas hydrate phase equilibrium conditions are reported widely in the literature. However, the data available for natural gas hydrates (NGHs) in real marine conditions are limited. In this study, NGH dissociation conditions in bulk brine and…
Methane transportation in tight sedimentary rocks results in significant and complex isotope fractionation. Existing models and mechanistic studies of isotope fractionation cannot fully explain the actual observations in gas transport processes that…
In order to explore the changing law and influencing factors of the filtering performance of natural gas filter elements under high pressure conditions, four types of filter elements were selected as the research objects, and field tests and…
The use of Nuclear Magnetic Resonance (NMR) logs for petrophysical interpretation and evaluation in the oil and gas industry has increased in recent decades, especially in Brazil, where the use of this technology was increased by more than 400% from…
Pore structure and connectivity are key factors that determine the quality of tight sandstone reservoirs, which are a frontier field for exploration worldwide in the 21st century but are quite challenging to characterize. Here we explored novel…
The performance of coalescing filter cartridges (of four different specifications) after a 410-day field operation for the high-pressure natural gas purification has been evaluated in this study. Our evaluation of field-tested filter cartridges…
