The need for petroleum is increasing along with the development of the industry, while the production results from the process of recovering oil from the reservoir by using primary recovery and secondary recovery are still very low so that it takes an advanced stage, namely tertiary recovery or, known as EOR. EOR is a method that produces oil production above 50%. EOR is an effort to increase oil production, so it is included in the IOR (Improved Oil Recovery) section. EOR consists of various applications, ranging from water injection, chemical injection, gases injection to microbiology injection. The stages in the injection of water and gas still leave oil trapped in the rocks in the reservoir. MEOR is one method that can be used to bring oil trapped in reservoir rocks to the surface. The effectiveness of the MEOR method is measured based on several parameters that is formation temperature, oil viscosity, permeability, saltwater salinity, water cut, API gravity crude oil, pH, pressure, residual oil saturation, porosity depth and bacterial content in the reservoir.

The development of heavy oil reservoirs under steam injection methods is facing multiple challenges due to the volatility of oil markets, energy efficiency, and new and stricter environmental regulations. This study aims to summarize the advances of a Research and Development (R&D) program established by Ecopetrol in 2018 to identify potential opportunities to improve the recovery performance of steam injection projects in heavyoil reservoirs in the Middle Valley Magdalena Basin (VMM) of Colombia.This paper summarizes an approach used to evaluate downhole heating and hybrid steam injection technologies assisted by basic benefit-cost ratios and energy and environmental indexes.Specifically, the methodology is described for the identification of optimum development plan scenarios for heavy oil wells. This study also summarizes recent advances in laboratory studies for the evaluation of hybrid steam flooding technologies (steam plus flue gas and solvents) and provides updates on the hybrid cyclicsteam-foam pilot carried out in two VMM wells.The proposed approach represents a fast screening method that has proven to be valuable in supporting management decision-making to allocate resources for laboratory and engineering studies to evaluate thermal enhanced oil recovery (tEOR) technologies in Colombia. The proposed methodology has also contributed to reducing the implementation cycle of tEOR technologies following the reservoir analog description ofreserve analysis. The latter was validated with the successful pilot results of the hybrid steam injection with foams implemented in July 2019.

“…However, the main limitation of this type of oils is their high viscosity and density, which challenge and complicate their exploitation and production. − Therefore, research on enhanced heavy oil recovery (EOR) methods is essential to increase the rate of heavy oil production on one hand and on the other hand to improve the quality of the obtained oil as well . Until now, water injection, chemical injection, gas, and thermal injection have been considered the main proposed methods in the field of EOR. ,,,− However, thermal methods are widely believed to be the most important enhanced oil recovery methods in terms of the produced oil quality and economic aspects. According to the literature, in situ combustion (ISC) as a subset of the thermal injection method has been always considered as an effective and appropriate technology, especially when it comes to heavy oil reservoir exploitation. − Basically, this technology consists mainly of air injection into the reservoir under high pressure to provide the necessary conditions for initiating oxidation reactions and promoting a stable combustion flame front for a better oil recovery factor.…”

In recent years, protection of the environment from activities associated with enhanced oil recovery has been considered a crucial priority for decision-makers in the international community. The in situ combustion process as a promising thermal enhanced oil recovery method has been attracting considerable interest in terms of improving oil production and environmental protection. However, this technique is not yet well studied. This paper outlines a new approach to improve the process of heavy oil oxidation by designing new biobased oil-soluble catalysts that are able to maintain and stabilize the combustion flame front of the in situ combustion process. A comprehensive theoretical and experimental study including thermal analysis (thermogravimetry/differential scanning calorimetry, TG/DSC) and quantum calculations was used to shed light on the effect of the ligand structure in the oil-soluble catalytic system on the heavy oil oxidation process. The obtained accurate results proved that metal interaction with the designed ligands increased, which led to a decrease in the energy of activation and an increase in the heavy oil oxidation reaction rate. Besides, the obtained DSC curves showed one peak in the presence of Cu and biobased ligands, contrary to the curves obtained for heavy oil oxidation reported with other ligands and metals. In other words, the obtained catalysts merged low-temperature-and high-temperature oxidation regions into one region. These findings reveal that the structure of ligands can significantly affect their interaction with metals in oil-soluble catalysts, and therefore the efficiency of catalysts is dramatically improved. We believe that our work could be usefully employed for further studies to clarify the mechanism of the in situ combustion behavior of heavy oil for a better impact on the environment.
