... combustion (ISC) in Chichimene field, starting in September 2019. Based on international ISC field experiences, this pilot represents a unique case study given the depth (≈8,000 ft) of this heavy crude oil (9 °API) reservoir. The pilot project consists of one injector, seven producers, and two temperature...

...-18 enriched water (H 2 O 18 ) were used as connate water in two different in-situ combustion experiments using a conical tube. Aside from fundamental understanding of the role of such reactions in in-situ combustion, the results could also potentially help in optimizing in-situ hydrogen generation...

... reservoir in Mexico, referred to as “A” field. The implementation of the pilot test was preceded by its corresponding laboratory study, which consisted of five accelerating rate calorimeter (ARC) tests and two combustion tube (CT) experiments. The analysis of the aforementioned experimental work led us...

... of the stabilized combustion front. After the experiment, sectional extraction of the core material from the experimental setup was performed. Each sample was packed in a sealed plastic bag for subsequent core analysis (Fig. 3). Fig. 3— Core analysis workflow. Measurements were carried out...

... effluent had reached the initial value measured from the recombined oil through the bypass and PVT tests. In this section, the experimental results are summarized and discussed. A series of immiscible and miscible gas injection coreflood experiments were performed using limestone reservoir cores...

... was experimentally tested in the loading NPs from 0.01 wt% to 0.5 wt% by the contact angle method. Wettability studies have shown that nanofluids can influence wettability variability from oil-wet to water-wet quality. About 0.05 wt% of NPs was found to be the optimal concentration to affect wettability change...

.... In terms of applicability of these ML models, two sets of experimental data were needed as input; the first was the analytically estimated K r curves from the steady-state drainage coreflooding experiments, while the other was the P c curves estimated from centrifuge or mercury injection capillary pressure...

... for low-permeability tight rocks. We use this experimental data to tune the empirical constants of the MBC model. The proposed method is based on a simple mathematical technique that uses assumptions of frontal advance theory to model the pressure drop along the core plug during two-phase immiscible...

... is an iteration process in which tuning of relative permeability curve characteristics is required to fit the displacement data obtained from the experiments using a reservoir simulator. In this study, the IMEX package of the CMG suite was used to history match the experimental production and pressure drop data...

We successfully verified the reliability of the new workflow with experimental measurements. Estimated water saturation using the introduced workflow resulted in an average relative error of less...

... experiments and calibrated the laboratory-scale model compared with experimental measurements. We then upscaled numerical simulation to a 3D geometry incorporating a geomechanical model. The change in scale is significant as the combustion tube is 6.56 ft (2 m) in length, whereas the dimensions of the 3D...

Both experiments were conducted at reservoir conditions to consider the phase behavior at elevated pressures and temperatures...

With the base stateful configuration from state settings experiment, an increased number of lag observations of oil production was tested next to determine the effect on prediction accuracy. The experimental design ( Brownlee 2019b ) was followed to first explore the effects of the additional...
