Vol. 12 No. 2 (2022)
In this second edition, volume 12 of CT&F, five articles were published. An article from the offshore group of Exploration of Ecopetrol studies the geological characterization of mud volcanoes located in the Caribbean area of Colombia and relates it to the sedimentary evolution of this area of interest to explore natural gas. In another paper, whose authors are from Universidad Central de Venezuela, several crude oils from the Maracaibo basin are characterized, identifying two types of source rocks: marine shale and terrigenous.
A third article proposes a methodology for full-waveform inversion processing based on a synthetic data set, showing how each step of processing affects the results.
From the Autonomous University of Ciudad Juarez, Mexico, and the University of La Rioja, Spain, an article develops a feasibility analysis of using wind energy in Ciudad Juarez, concluding that it is not feasible to install wind turbines in this city.
Finally, an article from the Bursa Udulag compares the performance of two types of cycles; the New European Driving Cycle and the Worldwide Harmonised Light Vehicles Test Procedure, comparing emissions, fuel consumption and power efficiency.

Vol. 12 No. 1 (2022)
Continuing with our emphasis on highlight research, development and innovation works related to the energy transition and decarbonization, in this new edition of CT&F we are publishing two articles related to renewable energies: one on the evaluation of geothermal potential in the Llanos basin of Colombia and another on the evaluation of the potential use of small wind turbines for electricity production in the region of La Guajira.
Two articles contain environmental topics such as the evaluation of the biodegradability and toxicity to water fleas of the use of scleroglucan as an additive to improve water flooding of crude oil reservoirs and the use of climatological mathematical models to simulate oil spills in environments, using as a case a previous oil spill that occurred in the Gulf of Morrosquillo.
An article is directly related to decarbonization and it develops a model of the phenomena that occur during the homogeneous combustion of the gases produced when an oil reservoir is subjected to in situ combustion methods.
Finally, two articles are related to the oil industry; one to the effect of the structure and molecular weight of naphthenic acids extracted from a crude oil on corrosion rate of carbon steel and another on the effect of antenna type on full-wave inversion methods.

Study of the combustion properties of premixed Hydrogen / Natural Gas / Air
Vol. 11 No. 2 (2021)In 2021, there was a significant recovery of global demand for liquid fuels due to the economic recovery programs that many countries implemented to mitigate the fall of their economies. The massive vaccination programs, and the resulting decrease in mortality from Covid-19 made society more confident to advance in this recovery.
Globally, since late January 2022, there has been a significant decrease in cases of contagion and deaths caused by Covid-19, although there is a resurgence of cases, so far marginal, in some regions of Asia. Hence, it seems that Covid-19 is becoming an issue of the past.
Now, a new cause of uncertainty in the world energy market has arisen, that is, the war in Ukraine. The severity of sanctions against Russia and their compliance, Western Europe's support to Ukraine, Russia's response to such support, the duration of the war, and even the possible use of nuclear weapons, will be key for defining the outcome of this new event.
The foregoing, although important and painful, should not let us lose sight of the challenge for humanity to reduce greenhouse gas emissions into the atmosphere to limit global warming. Further development of technologies and innovation are necessary in response to this challenge. Green and blue hydrogen, CO2 capture and sequestration, renewable energies, and biofuels are essential technologies to advance in the energy transition.
In this issue of CT&F, we publish several articles of interest related to this transition challenge. The use of natural gas-hydrogen mixtures as fuel in combustion systems is, without any doubt, a way to reduce emissions from chemical plants and oil refineries. The use of double-stage Ranking cycles to recover heat from geothermal systems may be relevant to make the most of the heat from the earth's crust. The modification of conventional tools to simulate processes with oxygen-containing molecules is essential for the synthesis and analysis of new processes in the fuel and petrochemical industry. Natural gas will be a key fuel in the energy transition, and efficient development of these assets will become increasingly important.

Volumen 11 No. 1 - 2021
Vol. 11 No. 1 (2021)The Covid-19 pandemic is still setting the pulse of humanity. Although great progress has been achieved in its treatment, developed countries have managed to vaccinate large portions of their population and many developing countries are struggling to significantly increase their vaccination rates; more contagious variants of the virus are emerging that have forced governments to propose new strategies such as booster doses, health passports, and more rigorous control on their borders.
Such situations are being reflected on the energy markets that are showing significant demand recoveries, although some uncertainty is perceived due to the possible need to impose new mobility restrictions.
This 2021 summer has been the warmest of the last century and a half, which is one more evidence of climate change effects. Droughts, forest fires, and record temperatures in several regions of the United States and Canada, floods and landslides never experienced in Germany, and extreme heat waves in various regions of Europe were recent news. The UN's group of experts on climate change has just published its sixth report in which it insists on the imminent need to reduce greenhouse gas emissions if we do not want to have points of no return regarding the planet's climate.
This environment suggests that the energy sector will undergo significant changes in the future. A significant growth in electric power demand and the development of renewable technologies will be the lead agents of energy transition.
In the same vein, our scientific journal CT&F has been expanding its spectrum of action from oil and gas themes to issues related to biofuels and renewable energies, so that we can promote communication and scientific and technological development that is so much needed in these times of energy transition. The exchange of ideas can lead us to new ways of addressing the enormous challenges that we are facing as a society.
This issue includes several articles on power generation from renewable sources and its social acceptance, evaluation of performance over time of photovoltaic cells, production of reducible sugar from residual biomass, as well as the evaluation of biodegradable polymers to increase the recovery factor of crude oil fields, and the use of ultraviolet light to control bacteria that produce biocorrosion in injection wells.
It also includes several articles on seismic processing techniques, an assessment of how innovation leveraged on international peers has enabled several countries to develop their unconventional sources, and the use of computational fluid dynamics in the simulation of a down – flow reactor.

Special issue on EOR
Vol. 10 No. 2 (2020)CT&F Journal dedicates this special issue, including relevant Colombian and international (Argentina, Canada, Norway, and the U.S) studies describing different EOR technologies and methods addressing topics of interest for the oil and gas community. This special edition includes ongoing research in SmartWater technology and a practical methodology for interwell water tracer programs. This volume also contains a numerical simulation study of CO2-EOR based on produced CO2 enriched using Oxycombustion providing an overview of the integrated vision of EOR and the reduction of carbon footprint. In this issue, Thermal EOR methods include downhole heating technologies (DHHT) and a numerical simulation study evaluating different strategies combining DHHT and hybrid cyclic steam methods considering its evaluation based on oil recovery, energy efficiency, and environmental indexes. Finally, research studies on Chemical EOR (cEOR) are included in this volume focused on advanced chemicals tolerant to high temperature (i.e., AMPS) and mechanical degradation (i.e., biopolymer and polymeric surfactants). A comprehensive review of the use of nanoparticles to improve the thermal resistance of synthetic polymers was also included as an alternative approach to enhance the performance of EOR polymers. Studies related to the mechanical degradation of polymers are complemented with papers describing experimental and CFD simulation methodologies contributing to the design of cEOR in Colombia.
Both CT&F and Ecopetrol hope to continue promoting and contributing to developing a network of professionals and knowledge dissemination integrating EOR and energy transition areas in years to come.
