  • 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.

  • Vol. 10 No. 1 (2020)

    In line with these priorities of the industry, this issue of CT&F (Volume 10, Number 1, 2020) includes three articles related to geology in southern Colombia whose authors belong to various Colombian universities and to Ecopetrol, one article on a method to improve seismic inversion, one that proposes using gas transportation at high density conditions for recent offshore discoveries in Colombia, and three articles focused on energy management in real-time, the use of an additional protection layer in industrial plants called super-alarms, and the design of photo-reactors based on fluid computational dynamics

  • Vol. 9 No. 2 (2019)

    This issue includes five research articles focused on the operating segments of O&G industry (Exploration, Production, Transport and Refining), one article on environmental technology and another three articles regarding renewable energies and Biofuels. 

    This issue hosts the paper “Submarine Canyon-Fill Reconstruction from integrated Seismic-Stratigraphic Analysis – Application to Banquereau Formation, Scotian Basin – Offshore Canada” by Chajin et al. This paper is relevant for the economic importance of ancient deep water deposits.

    The paper of Chajin et al. contributes with a 3D stratigraphic model that might be used as an analog for similar reservoirs in the Scotian Basin and other reservoirs for similar tectonic settings, providing key insights and vital information for decision making in deep water reservoirs.

     

  • Vol. 9 No. 1 (2019)

    On this issue we are publishing four with themes of Reverse Time Migration, modeling of seismic waves into an elastic media, reservoir characterization based on geochemical and well logs data and finally an article of diagenesis of tight sandstone.  Special focus in the present issue on environmental aspects is done. So, four papers related with soil remediation, with photocatalytic degradation of hydrocarbons, with oils spills in rivers and a remarkable study about on-road vehicle emission factors in Colombia conforms a block that aim to contribute to get a better understanding about the environmental burdens in the industry.

    Respecting to Oil Production segment, this issue includes a methodology for calculating performance indexes for Enhanced Oil recovery by air injection, a combined artificial intelligence modeling for forecasting and also an assessment of surfactant-polymer formulation for EOR. About integrity and materials topics, an evaluation of high density polyethylene as an alternative for corrosion control in pipes is also included.
