Autonomous driving has attracted significant research interests in the past two decades as it offers many potential benefits, including releasing drivers from exhausting and mitigating traffic congestion, among others. Despite promising progress, lane-changing remains a great challenge for autonomous vehicles (AV), especially mixed dynamic scenarios. Recently, reinforcement learning (RL), powerful data-driven control method, been widely explored decision makings AVs with encouraging results...
Oil reserves of the thin heavy oil reservoirs are estimated to be over 400 billion barrels. The recovery factor water-flooding in these is as low 10–20% due high viscosity and correspondingly unfavorable mobility ratio. In addition, commonly used thermal methods also unsuitable such formations significant heat loss adjacent formations. Thus, it urgent find an efficient economic enhanced (EOR) method maximize factors reservoirs. this study, feasibility polymer-enhanced foam (PEF) flooding for...
Heavy oil is estimated to account for about 70% of the remaining reserves and considered as most promising readily available resource meet energy demands in coming decades. However, traditional enhanced recovery (EOR) methods heavy face significant challenges, such high mobility injected fluids, polymer degradation, surfactant adsorption, chemical consumption, considerable water greenhouse gas emissions, operation costs, need robust facilities. Recently, nanoparticle technology has been...
Carbamoyl phosphate synthetase 1 (CPS1) deficiency, a urea-cycle disorder, results in hyperammonemia initiating sequence of adverse events that can lead to coma and death if not treated rapidly. There is high unmet need for an effective therapeutic this especially early neonatal patients where mortality excessive. However, development adeno-associated virus (AAV)-based approach hampered by large cDNA size protein requirement. We developed oversized AAV vector as gene therapy treat CPS1...
Abstract Surfactant Polymer flooding (SP flooding) has drawn more attention than Alkaline (ASP in China due to the difficulty of demulsification and scale formation problem from alkali ASP. Traditionally, primary requirement for surfactant SP is lowest interfacial tension (IFT). However, core tests performed a series heterogeneous models have demonstrated there exist optimized IFT polymer viscosity flooding, which can maximize oil recovery formation. The low value but not possible value, at...
Abstract Polymer flooding is one of the most important EOR technologies currently producing substantial oil increment in China onshore oilfields. The application polymer offshore environment more complex and face to many technical challenges due absence fresh water source limited space on platform. Compared regular anion polyacrylamide mostly used oilfields, hydrophobically associating water-soluble (HAWP) could keep relatively high viscosity salinity brine. A kind HAWP was introduced first...
Reducing the heat loss in wellbore is key for efficient development of geothermal resource. It a reliable solution to establish long-term stable with good thermal insulation through cementing. In this paper, cement-based composite material was prepared by using cement as cementing material, hollow glass beads, foaming agent and stabilizer main raw materials, other conventional admixtures. Foams beads can introduce gas low conductivity into cement, so improve material. are produced chemical...
In view of the limited applicability traditional chemical flooding and binary composite for heavy-oil reservoirs, branched-preformed particle gel (B-PPG) with excellent plugging performance was added to construct B-PPG/SP (B-PPG/surfactant/polymer) system. Through sand pack experiments, it has been proven that synergistic effect between B-PPG polymer can expand swept area increase contact viscosity reducer heavy oil, enabling better exert emulsification reduction effects. The B-PPG, further...
For any project that is supported by a risk analysis, the assessment generally needs to evaluate consequences of health, safety and environmental (HSE) impacts, geological CO2 storage projects are no exception. To date, however, assessments have focussed more on performance reservoir in terms its ability contain or at least prevent leakage surface near-surface environment, rather than determine potential impacts (and gases such as H2S radon may be transported with CO2) specific targets. This...
The condensate blockage causes a substantial decrease in well productivity for gas reservoirs. Based on the previous studies, novel experimental method was designed to evaluate and mitigating effect of injection. considers stacking near wellbore region flow far region. There is an intermediate vessel containing at entrance core holder apparatus. In process pressure depletion experiment long model, connected remains above dew point pressure. seriousness investigated by this research. When...
Polymer flooding has been proven to effectively improve oil recovery in the Bohai Oil Field. However, due high viscosity and significant formation heterogeneity, it is necessary further displacement effectiveness of polymer heavy reservoirs service life offshore platforms. In this paper, effects water/oil mobility ratio dimensionless productivity index on were studied utilizing relative permeability curves. The results showed that when water saturation was less than value, where equal 1,...
A thorough understanding of the effects lean zones and improvement steam-assisted gravity drainage (SAGD) operations with such heterogeneities is critically important for reducing disadvantages zones. The numerical model shows: (1) SAGD most influenced by single-layer zone above-injector (AI) location; decrease interval distance increase thickness water saturation in zones, detrimental effect on performance increases; (2) period connate initial saturations multiple-layer (3) injection...
The Chang 7, 8, and 9 members of the Triassic Yanchang Formation in Fuxian–Ganquan area Ordos Basin all develop lacustrine shales. However, current geological research shale oil gas exploration mainly focus on 7 shale, with little attention given to 8 formations. Based experimental data from whole-rock mineral analysis, organic geochemical field-emission scanning electron microscopy hydrocarbon generation simulation experiments, combined well-logging data, distribution, composition, source...
A briefing document was prepared two years ago as the basis for dialogue with regulators responsibilities in area of CCS.
