In this study, a compound surfactant system composed of alkyl polyglucoside (APG) and amine oxide (OAE) was formulated to synergistically stabilize the oil-in-water emulsion for enhanced oil recovery (EOR). Dewatering ratio, droplet size distribution, interfacial tension (IFT), stability, microscopic displacement performance were investigated. The smallest lowest IFT, indicating presence most stable emulsion, are observed when total mass concentration ratio APG/OAE 0.5 wt % 7:3,...
Nanofluids, as a novel material for tertiary oil recovery, have shown promising potential in enhancing water flooding efficiency low-permeability reservoirs and increasing recovery rates. However, the risk of particle agglomeration arises when size is too small. Challenges such maintaining dispersion stability, efficient long-distance transportation nanofluids, preventing retention emerged key obstacles hindering widespread adoption large-scale implementation nanoflooding technology various...
Modified starch and other natural polymer materials have found extensive applications in drilling fluids. However, conventional modification methods offer limited scope for further enhancing their temperature resistance, typically with the applicable being below 140 °C. This paper presents preparation of composite plant phenols using walnut shells, peanut straw, lignin, which are rich fundamental “three elements” plants. To explore improvement resistance cellulose-based fluid additives, this...
In this study, based on existing heavy oil extraction technology, combined with the mineral composition in a reservoir, synergistic catalytic effect of reservoir minerals and exogenous catalysts under reaction system hydrogen-rich environment not only reduces viscosity thick but also cost further improves recovery rate oil. impacts different aquathermolysis were investigated. The research results showed that sodium montmorillonite within exhibited an optimal effect, catalyst C-Fe (catechol...
Most of the oilfields are currently experiencing intermediate to late stages oil recovery by waterflooding. Channels were created between wells water injection and its effect on is less. The use plugging profile control required excessive production from an reservoir. First, well selection for using fuzzy evaluation method (FEM) improvement random forest (RF) classification model investigated. To identify operation, a with four factors established; then, machine learning RF algorithm was...
The CO2 huff-n-puff process is an effective method to enhance oil recovery; however, its utilization limited in heterogenous edge-water reservoirs due the severe water channeling. Accordingly, herein, a stable N2 foam proposed assist for enhanced recovery. Sodium dodecyl sulfate (SDS) and polyacrylamide (HPAM) were used as surfactant stabilizer, respectively, 0.3 wt% of SDS + HPAM screened laboratory generate with good foamability long stability. Subsequently, dynamic tests using 1D sand...
Abstract This study presents a novel approach for the reuse of uncontaminated fracturing flowback fluids to improve inhibitory and lubricating properties water-based drilling (WBFs), curb environmental pollution arising from fluids, substantially mitigate expenses associated with WBFs. The experimental design was optimized using orthogonal experiments range analyses, whereby modified rubber powder set at 2.0%, xanthan gum 0.15%, plant phenol complexing agent ratio 1:0.01. assessment...
The major oil fields are currently in the middle and late stages of waterflooding. water channels between wells serious, injected does little effect. importance profile control blocking has been identified. In this paper, decision-making technique for shutoff is investigated by fuzzy evaluation method, FEM, which improved using a random forest, RF, classification model. A machine learning forest algorithm was developed to identify candidate predict well performance operation. data set...
Introduction Since shallow-buried oil reservoirs of Nanpu Block, Jidong Oil Field, China belong to complex fault-block reservoirs, effective flooding networks are difficult be established compared with other conventional reservoirs. Although horizontal wells widely used in the field expand drainage area, severe water invasions still happened after years development [1,2]. Cyclic CO2 injection, also known as huff-n-puff, was then conducted enhance recovery (EOR) since 2010, and great profits...
Abstract In order to solve the problem of rapid increase in water content and decrease production after flooding fault block reservoirs, air foam experiments static low temperature oxidation, single double sand filled tube were carried out. The results showed that there was no absolute relationship between oxygen consumption viscosity crude oil, a turning point saturation. reaction rate is greatly affected by temperature. displacement efficiency pipe increased about 15%. injection can...
This paper focuses on the synthesis of polyhydroxy small molecule amines using mixed as raw materials. The anti-swelling experiment, swelling shrinkage linear rate and clay hydration experiments were used to evaluate application effect synthesized products in oilfield water-based drilling fluids. suitable inhibitors selected. inhibition mechanism was investigated by TGA, laser particle size analysis SEM. best at a concentration 0.1% with 1:3 mass ratio phosphoric acid, i.e., product HS-1....
