Abstract Data-driven methods serve as robust tools to turn data into knowledge. Historical generally has not been used in an effective way analyzing processes due lack of a well-organized data, where there is huge potential turning terabytes With the advances and implementation data-driven models have become more widely-used analysis, predictive modeling, control optimization several processes. Yet, industry overall still skeptical on use methods, since they are data-based solutions rather...

Summary This paper presents a novel technique to determine multicomponent diffusion coefficients for carbon dioxide (CO2) injection in North Sea chalk field (NSCF) Norway at reservoir conditions. The constant-volume-diffusion (CVD) method is used, consisting of an oil-saturated-chalk core contact with overlying free space, which filled the CO2. experimental data are matched equation-of-state (EOS) -based compositional model. Transport by controls dynamics constant-volume system and, together...

Solvent injection has been considered as an efficient method for enhancing oil recovery from fractured reservoirs. The success of this therefore depends on the degree enhancement mass exchange rate between solvent residing in fracture and matrix. If transfer would be solely based diffusion, unacceptably slow. A series soak experiments have conducted to investigate In a experiment, porous medium containing is immersed open space simulate matrix fracture, respectively. We use CT scanner...

Summary The main focus of this paper is to present experimental and simulation results that describe carbon dioxide (CO2) injection in a chalk sample with fracture/matrix interaction at reservoir conditions. On the basis experiments, models were built mimic transport phenomena, including diffusion, which was found be particularly important. first experiment consisted vertically oriented Sigerslev outcrop core, where single “fracture” represented by centralized hole along core. Both matrix...

In naturally fractured reservoirs, improving the matrix–fracture interactions is critical to success of applied improved oil recovery method. Therefore, a study mechanisms that control mass exchanges between fracture and matrix can help optimize recovery. This paper concerns an experimental simulation investigate performance gas–oil gravity drainage process in reservoirs. this study, five gas injection experiments were conducted at different miscibility (i.e., immiscible fully miscible)...

Abstract We use a three-dimensional mixed-wet random network model representing Berea sandstone to compute displacement paths and relative permeabilities for water alternating gas (WAG) flooding. First we reproduce cycles of injection observed in previously published experimental studies. predict the measured oil, accurately. discuss hysteresis trends compare behavior water-wet oil-wet media. interpret results terms pore-scale displacements. In media permeability is lower presence during...

Abstract Artificial lift systems (ALS) should be thoroughly analyzed to minimize non-productive time, increase production and reserves, reduce cost failure, maximize capital efficiency. This work proposes a novel systematic for ALS analysis approach that implements data analytics historical performance tracking benchmarking, heuristic diagnostics suboptimal identification, reliable model-based solutions opportunity evaluation. The proposed methodology follows the principles of integrated...

Abstract A significant proportion of the world remaining oil reserves is residing in fractured reservoirs. Conventional recovery mechanisms may result low efficiencies such Gas injection be one few techniques, which can boost production from these resources. However, higher capillary pressures associated with matrix blocks coupled extreme hydraulic contrast between and fractures ultimate factors significantly lower than equivalent non-fractured systems. Miscible or near-miscible gas...

Abstract Decline curve analysis (DCA) is one of the most widely used forms data that evaluates well behavior and forecasts future field production reserves. Usually, this practice done manually, making assets with a large number wells cumbersome time-consuming. Moreover, results are subject to alternate interpretations, mostly as function experience objectives evaluator. In work, despite common industry, i.e. manual DCA, we developed deployed cutting-edge technologies intelligently apply DCA...

Abstract Gas oil gravity drainage is an effective recovery process, which has been proven in the field. Under favorable conditions displacement stable and for right surface tension combinations residual saturation low. In absence of gas dissolution, after injection usually low as a large amount remains capillary trapped matrix blocks. However, when main constitutes soluble oil, dissolution leads to mixing interfacial (IFT) reduction, cause enhanced transfer between fracture. Therefore, study...

Our validated models reproduce result experiments. addition, we upscale simulation model investigate scale dependency diffusion mechanism in larger matrix-fracture domain. experiments used which vertically placed core-holder total...

Miscible gas or solvent injection has received increasing attention in recent years as an efficient method for improving oil recovery from naturally fractured reservoirs. Because of the large permeability difference between fracture and matrix, success this depends to a extent on degree enhancement mass-exchange rate flowing through residing matrix. In study, series experiments were conducted investigate mass-transfer matrix when is injected system. The effects rate, aperture, water...
