The Southern Hemisphere westerly winds (SWW), a belt of strong zonal in the mid-latitudes, play key role climate variability. Recent intensification and southwards migration SWW is projected to continue due anthropogenic change despite recovering Antarctic ozone hole, impacting regional hydroclimate, ocean circulation carbon cycling. Despite importance SWW, our understanding their behaviour on centennial millennial timescales limited by inherently short observational record palaeo-archive...
Abstract Indonesia has officially declared its withdrawal from OPEC membership in September 2008 because of failing to meet oil production quota as what is determined. For that reason, effective and environmentally friendly methods need be applied Indonesian reservoirs; one them Microbial Enhanced Oil Recovery (MEOR). This method involves the knowledge biotechnology petroleum engineering aimed improve recovery old marginal wells. paper presents laboratory investigation bacteria ability live...
Abstract Enzyme Enhanced Oil Recovery (EEOR) has recently been categorized as one of the most effective EOR mechanisms. Laboratory and field studies have reported up to 16% incremental oil recovery rates. EEOR recovers mainly by two main mechanisms: lowering interfacial tension between brine altering wettability on rock grains a more water-wet condition. Therefore, would promote mobilization capillary-trapped after regular waterflooding. Since resides at micro-scale, it is essential assess...
The rapid development of X-ray micro-computed tomography (micro-CT) opens new opportunities for 3D analysis particle and grain-size characterisation, determination densities shape factors, estimation mineral associations liberation locking. Current practices in are based on 2D representations leading to systematic errors the extrapolation volumetric properties. New quantitative methods tomographic data therefore urgently required characterisation deposits, processing, tailings, rock typing,...
Abstract Nitrate injection is a common approach used to control reservoir souring. This method relies on nitrate reducing bacteria (NRB) ability suppress sulphate (SRB) growth. These experiments were conducted investigate the underlying principal of stainless steel material. Anaerobic tests performed by immersing UNS S31603 samples for 28 days at 50°C in electrochemical cells containing 10% crude oil brine water, supplemented with sodium nitrate. Four different conditions evaluated: cell (no...
Summary Analysis of produced water is one few direct sources information to the subsurface processes active in an oil field. However, revealed geochemical patterns are typical complex and require a multidisciplinary approach successfully unlock decode. The Halfdan field initially contained two main types formation brine but now, after 15 years extensive flooding, contains mostly seawater modified type. initial was low salinity sulphate-depleted type medium high saline sulphate-rich that...
The platypus and four echidna species are the only living egg-laying mammals sole extant representatives of Order Monotremata. echidnas very disparate both morphologically ecologically: is a specialized semiaquatic burrowing form that forages for freshwater invertebrates, whereas fully terrestrial adapted feeding on social insects earthworms. It has been proposed evolved from semiaquatic, platypus-like ancestor, but fossil evidence such profound evolutionary transformation lacking, this...
Summary During core flooding experiments where water is injected in residual oil saturated plugs, the fluids are often produced small amounts. Oil and come out of collected glass vials using a fraction collector. Quantification these difficult since volume might be less than few microliters. In this study, we approach determination volumes effluents predetermined amounts North Sea with synthetic seawater. The UV/visible spectroscopy method low-field NMR spectrometry compared for...
Bacteria selective plugging is one of the mechanisms through which microorganisms can be applied for enhanced oil recovery. plug water-bearing zones a reservoir, thus altering flow paths and improving sweep efficiency. It known that bacteria penetrate deeply into reservoirs, however, complete understanding penetration behavior lacking, especially in chalk formations where pore throat sizes are almost comparable with vegetative cells. This study investigates chalk. Two types, spore forming...
Within geological samples, understanding the 3D distribution and concentration through mineral liberation analysis is vital for characterization in resource industry energy environmental applications.While there are existing techniques available that can provide this identification 2D with SEM-based methods [1], a lack of providing analogous representations.Here, we present method using machine learning to obtain phase information from combined μ-XRF μ-CT methodology essentially propagates...
