Comparative Results

The Surfactant-Polymer (SP) process is a type of Chemical Enhanced Oil Recovery (CEOR) method. They are still a challenge for the petroleum oil industry mainly because of the difficulty in designing and forecasting the process behavior on the field scale. Therefore, understanding of the phenomena associated with a CEOR process is of vital importance. For these reasons, this work discusses the benefits of Computed Tomography (CT) uses for the experimental assessment of a SP process. The research includes a literature review that allows identifying the main CT usages for petroleum engineering and a discussion concerning the effectiveness of mathematic expressions proposed for the tomography images treatment of two-phase flow displacement. The conducted experimental methodology can be reproduced to assess the benefits of any chemical Enhanced Oil Recovery (EOR) process with CT. Thus, this paper assesses the conventional waterflooding (WF) and SP flooding as secondary and tertiary oil recovery methods. The developed study allowed us to evaluate through CT images the porosity and the saturation profiles along the rock sample. Also, CT processed data enabled checking the volumetric material balance and determine the oil Recovery Factor (RF). The doubled checked SP data showed an RF increase of 17 and 10 percentage points for secondary and tertiary chemical injection schemes respect to conventional waterflooding. Finally, comparative results of the water cut (Wcut) evidenced the mobility ratio improvement and reduction on the remaining oil saturation.

Hele Shaw Cell

We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as “polymer flooding”) enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele–Shaw cell pre-saturated with oil, our laboratory model of an oil reservoir, and is given an aqueous solution of known polymer concentration to inject into the model reservoir to “push” the oil out. At selected intervals, students record the oil produced, take photos of the cell using their smartphones, and demarcate the invading polymer front on an acetate sheet. There is ample time for students to observe the experiments of other groups and compare the different flow patterns that arise from different polymer concentrations. Students share their results with other groups at the end of the session, which require effective data presentation and communication. Both the in-session tasks and data sharing require team work. While this experiment was designed for a course on Enhanced Oil Recovery for final year undergraduate and MSc students in petroleum engineering, it can be readily adapted to courses on groundwater hydrology or subsurface transport by selecting different test fluids.

Miscible Flow

The multiphase flow mechanism in miscible displacement through porous media is an important topic in various applications, such as petroleum engineering, low Reynolds number suspension flows, dusty gas dynamics, and fluidized beds. To simulate such flows, volume averaging spatial operators are considered to incorporate pressure drag and skin friction experienced by a porous medium. In this work, a streamline-based Lagrangian methodology is extended for an efficient numerical approach to handle dispersion and diffusion of solvent saturation during a miscible flow. Overall pressure drag on the diffusion and dispersion of solvent saturation is investigated. Numerical results show excellent agreement with the results obtained from asymptotic analysis. The present numerical simulations indicate that the nonlinear effects due to skin friction and pressure drag cannot be accurately captured by Darcy’s method if the contribution of the skin friction dominates over that of the pressure drag. Moreover, mass conservation law is investigated, which is an important feature for enhanced oil recovery, and the results help to guide a good agreement with theory. This investigation examines how the flow regime may be optimized for enhanced oil recovery methods.

Bacterial plugging agents for microbial enhanced oil recovery were peviously studied using non-hydrocarbon substrate. They lacked the ability to survive and form stable plug at high concentration of hydrocarbon compounds. As an alternative, hydrocarbon was used as substrate to determine the bacterial potential as plugging agent. In this study, Bacillus licheniformis Ta62bi was used to study the potential of the bacteria as plugging agent in polycyclic aromatic hydrocarbon (PAH)-rich condition. Three responses (growth, exopolysaccharides (EPS) and PAH consumption) were analyzed. The survivability pattern was observed at 72 hours. From the analysis, pyrene was the best PAH compared to naphthalene. It was based on increment of 214% (415 CFU/mL) in growth and 30% (0.759 g/L) in EPS production. However, the consumption of soluble PAH (0.002 to 0.015 mg/L) was low. The assimilation of hydrocarbon by potential bacterial plugging agent is the only means of survival. Otherwise, it would degrade to a great extent the oil components that  would lead to the reduction of the oil quality. Next, a two-level factorial design was conducted to analyze the effects of different concentration of pyrene (0.1 to 10 g/L) and temperatures (27°C to 50°C) to the responses. The results showed that both factors significantly affect the responses (P < 0.05). Both factors inhibited growth of bacterium Ta62bi. As the PAH concentration was  increased, the EPS production and PAH consumption was also found to increase at 27˚C.  At 50°C, there was an increase  in the EPS production but not in the PAH consumption. Therefore, EPS might be implied to having an important role in the tolerance of the TA62bi strain towards hydrocarbon. The findings will be further used  in future research as a model to predict and control  enhanced oil recovery plugging mechanism.

The purpose of this research is to get new product innovation process from bagasse, that is Sodium LignoSulfonate surfactant. Lignosulfonates surfactants in petroleum engineering are used as injection fluids into oil reservoirs to increase oil recovery, which is known as Enhanced Oil Recovery process. Lignosulfonates is made of lignin as raw material, which can be extracted from bagasse as one of its sources. Bagasse contains 24 - 25% lignin, so it is sufficient to be processed into lignosulfonates. Today, bagasse is one of the biomass resources widely used as a boiler fuel in sugar factory, source of animal feed, material for paper, cement and brick reinforcement .This study presents an innovation of bagasse utilization. This innovation involves two scientific application fields, firstly, chemistry in the processing of bagasse into sodium lignosulfonates surfactant and secondly, petroleum engineering in the effort of using sodium lignosulfonates surfactant to increase oil production from the reservoir. The last stage in this process is injection of the sodium lignosulfonates surfactant into a synthetic core in laboratory scale use water and surfactant injection.. The amount of oil that is produced from the injected core shows the increase in oil yield from the sodium lignosulfonates surfactant injection.

Aim: Polymer flooding is used for enhanced oil recovery. Only polymers that can withstand harsh environments work best. HPAM is mostly the polymer used for enhanced oil recovery because it is available and cheap, but it does not withstand high temperatures and high salinity reservoirs. Xanthan Gum withstands high temperatures and high salinity reservoirs, but it is expensive and plugs the reservoir. The aim of this study is to compare the salinity stability of gum Arabic and Terminalia Mantaly, a novel biopolymer, with commercial Xanthan gum. Study Design: Locally formulated biopolymers from gum Arabic exudates bought from Bauchi State in Nigeria and from Terminalia Mantaly exudates obtained from the University of Port Harcourt. The appropriate rheological tests were carried out at the laboratory. Place and Duration of Study: The laboratory experiments were carried out at the department of Petroleum Engineering, Covenant University, Ota in Ogun State of Nigeria between 2020 and 2021. Methodology: The gum Arabic, Terminalia Mantaly and Xanthan Gum powders were dissolved in deionized water to get various concentrations in ppm. The polymers were mixed and kept for 24 hours to achieve a homogenous solution. The Automated OFITE® Viscometer at different revolutions per minute (RPM) of 3 (Gel), 6, 30, 60, 100, 200, 300, and 600 was used to measure the rheological properties of the various concentrations before Sodium Chloride (NaCl) and Calcium Chloride (CaCl2) of various concentrations were added and allowed to hydrate for another 24 hours before measuring their rheological properties again. Results: The study showed that Xanthan Gum, Gum Arabic, and Terminalia Mantaly biopolymers can be used in high salinity reservoirs. Terminalia Mantaly, a novel biopolymer, is insensitive to salinity in monovalent and divalent ions. Conclusion: Xanthan gum exhibited high viscosity even at low concentrations. Gum Arabic exhibited good tolerance to salinity at NaCl 3.5%. Terminalia Mantaly was very stable with both monovalent and divalent ions. Divalent ions have more effects on polymers than monovalent ions in reservoirs. Recommendation: It is recommended that Terminalia Mantaly be investigated more, as it can replace imported biopolymers for Enhanced Oil Recovery (EOR).

The features of evaluation of the effectiveness of flow deflection technologies of enhanced oil recovery methods. It is shown that the effect of zeroing component intensification of fluid withdrawal leads to an overestimation of the effect of flow deflection technology (PRP). Used in oil companies practice PRP efficiency calculation, which consists in calculating the effect on each production well responsive to subsequent summation effects, leads to the selective taking into account only the positive components of PRP effect. Negative constituents — not taken into account and it brings overestimate over to overstating of efficiency. On actual examples the groundless overstating and understating of efficiency is shown overestimate at calculations on applied in petroleum companies by a calculation.
