This has rapid growth has created challenges for the School as the numbers of teaching staff has lagged behind the number of students. In order to ensure our students continue to enjoy a high quality learning experience across the program, we tested innovative teaching techniques in our 3rd year Reservoir Engineering course. In this paper we discuss some reservoir engineering example to explain our improved teaching techniques. Students in this course are assumed to have a sound grasp of the fundamental concepts of transport in porous media. Therefore, new content was introduced in the tutorials before the lectures. This swapping of the traditional order, requires students to actively apply existing knowledge to new environments and enables students to collaboratively construct knowledge of the course content in a p...

In case of a depleted oil reservoir, reservoir pressure is not sufficient to achieve miscible or near-miscible condition. This extended abstract presents numerical studies to delineate the effect of alcohol-treated CO2 injection on enhancing miscibility, CO2 storage and oil recovery at immiscible and near-miscible conditions. A compositional reservoir simulator from Computer Modelling Group Ltd. was used to examine the effect of alcohol-treated CO2 on the recovery mechanism. A SPE-5 3D model was used to simulate oil recovery and CO2 storage at field scale for two sets of fluid pairs: (1) pure CO2 and decane and (2) alcohol-treated CO2 and decane. Alcohol-treated CO2 consisted of a mixture of 4 wt% of ethanol and 96 wt% of CO2. All simulations were run at constant temperature (70°C), whereas pressures were determined using a pressure-volume-temperature simulator for immiscible (1400 psi...

All the experiments were done under unsteady state conditions with oil displacing brine in fully brine saturated cores. First, relative permeability curves are calculated using the Johnson–Bossler–Naumann (JBN) method (Johnson et al. 1959). Then, modified JBN model is defined to account for capillary pressure. Lastly, numerical simulator is used to generate relative permeability curves based on history matching. Results of the experiments show that as the rate increases (higher capillary number), the water relative permeability increases while the irreducible water saturation decreases. With high rate, less water saturation is being accumulated at the outlet hence less irreducible water and higher relative permeability. Moreover, the oil relative permeability curves are getting higher with higher ra...

Recent advances in imaging technologies have made it possible to directly resolve actual fluid distributions at the pore scale, thus capturing a large field of view for arbitrary wetting conditions, which are numerically difficult to reproduce. In previous studies, fluid distributions were not imaged under in-situ conditions, which may cause the oil (nonwetting) phase to snap off. Consequently, computed oil relative permeability is underestimated, particularly at low oil saturations. This study extends our previous work by imaging fluid distributions under in-situ conditions as a basis for numerical computations. In this study, we perform a steady-state flow test on a homogeneous outcrop sandstone (Bentheimer) core. First, the dry core is imaged in our microcomputed-chromatography (micro-CT) facility. Afterward, the core is fully saturated with 0.4 molar sodium i...

The students worked in teams to design and build a device to sequester “CO2” into a reservoir. We present our observation of the peer assessments, performance prediction and diversity of the students. We found that some teams collaborated more effectively than others. We quantified this effectiveness using an online peer assessment that enables students to rate the performance of their teammates. These ratings were incorporated into the assignment of individual marks for group assignments. The analysis of the marks students achieved for various assessments and components of the course is presented. We observed that female students tended to out-perform their peers in both individual and team assessments, and students who did well in individual components of the course also did well in the team components. The use of early assessments to predict performance in later assessments seems to be difficult. However, there is a strong connection between students’ results for their design proposal and their results for the final design work. We are able to show statistically a signifi cant improvement for marks for presentations but not for report writing. Anonymous surveys showed that about 90% of students were satisfi ed with their experience of the course. Students found this course to be challenging and enjoyable, giving them a good start in developing their skills as engineers.

The relative permeability also changes as the effective stress regime shifts from one state to another. This paper examines coal relative permeability trends for changes in effective stress. The unsteady-state technique was used to determine experimental relativepermeability curves, which were then corrected for capillary-end effect through history matching. A modified Brooks-Corey correlation was sufficient for generating relative permeability curves and was successfully used to history match the laboratory data. Analysis of the corrected curves indicate that as effective stress increases, gas relative permeability increases, irreducible water saturation increases and the relative permeability cross-point shifts to the right.
