Scope and editorial policy


The objective of CT&F is to publish the achievements of scientific research and technological developments of Ecopetrol S.A. and the research of other institutions in the field of oil, gas and alternative energy sources. The articles submitted must be original and innovative, in English; and neither previously published, nor simultaneously published in other journals.


    a) ARTICLES OF SCIENTIFIC AND TECHNOLOGICAL RESEARCH: documents which present in detail the original results of research projects. Document structure generally includes four important parts: Introduction, methodology, results and conclusions.
    b) ARTICLES OF CAREFUL CONSIDERATION: documents which present results from the analytical, interpretative, or critical perspective of the author, on a specific topic, referring to original sources.
    c) ARTICLES OF REVISION: documents that are the result of research that integrates, systemizes, analyzes and express a review on the results of published or unpublished scientific and technological research, by giving an account of the advances and development trends. These are characterized by presenting a careful bibliographical revision of at least 50 references.

Note: The manuscripts must be unpublished works. The opinion expressed in them is the sole responsibility of the authors. The reception of an article does not imply its publication; it shall be subject to various revisions and evaluations prior to publication.

    Theoretical Frame or State of the Technique: Presents the state of the technique in science (Only if it required for the development of the article).
    Experimental Development: It is where the authors describe the applied experimental design, and the more relevant experimental procedures or techniques necessary to obtain the results (detailed description of standard techniques must be avoided).
    Results: It presents the results that support the conclusions and scope of the article. The results must be supported with statistical information (number of standard observations and deviations, amongst others), if applicable.
    Results Analysis: They must be focused on the verification of the hypothesis and its confrontation to the state of the techniques.
    Conclusions: It is where the implications of the results, and their relationship to the proposed objective, are described.
    Acknowledgments: It should include the institutions or persons that have collaborated in the development of the article, or the work, object of the analysis within the article.
    References: Each of the bibliographical references (articles, books, standards, patents, etc.) that are specified in the document must be included in this section in alphabetical order. Results must not be referenced. The article must contain at least 10 bibliographical references.

Each appendix must contain only one type of information, be ordered as they appear referenced in the article, begin in a new page, and be identified with a title.

Abbreviations: The first time that abbreviations appear within the text, they must be placed between parentheses after the full expression. The abbreviations and symbols used must also be explained under the correspondent tables or figures.

Chemical formulas and mathematical expressions: The subscripts and superscripts in formulas must be clearly indicated.

The numbers that identify equations must be between parentheses and in italic, on the right of the equations.

Fractions in formulas must be written with a horizontal line. When stating them within the text they may be written with a slash.

Decimals must be separated by a period. To indicate thousands, half a space is included between the digits. Equations must be numbered in sequence and be referenced within the text in the following manner: Equation 3 (italic and first letter capitalized.) The terms of the equations and chemical formulas in the text should be in italic.

Figures: The term "Figure" is used for diagrams, photographs, and graphs. The notes related to the Figure are included under the figure and the information contained must be complete and with indicators that contributes to the article. The Figures do not require frames.

They should preferably be attached by a separate files in full color or easily readable as black and white, in JPG or in a PDF file, exported from the original program with a minimum resolution of 300 dpi and 9 cm size.

Tables: The title of each column must be short, with measurement units between parentheses. Notes related to the Table must be complete and should orient the reader and these are included under the Table.

Figures and Tables must have independent consecutive numbering.

All Figures and Tables must be referenced within the text before being presented. If a Figure or Table is based on information coming from a external source, the text must contain the whole bibliographic reference, just on the bottom side of the Figure or Table or inside the normal paper text.

The words "Figure" and "Table" should be in bold and without point as shown in the following example:

Figure 1. Visual examination of the fracture.
Table 1. Chemical composition of the materials evaluated.


References shall be located at the end of the text, not as footnotes. They must be complete and precise so they may be easily found by the reader; do not use links. In general terms take the following into account:

When quoting sources within the articles:

    a. If the author is not part of the sentence: the last name shall appear between parentheses, followed by the year of publication; e.g. “…it seems that in this case the influence of the radical inhibitors in the solution is minimal (Longman, 1977).” If it is necessary to mention two authors, the last names should be joined by an ampersand (&) within parentheses; e.g. (Engler & Tiab, 1996).

    b. If the author is part of the sentence: the last name is stated followed by the year in parentheses: e.g.”…to this purpose we have available the RANK_OBJ program developed by Deutsch (1998).”

    c. If two authors are referenced the last names shall be united by “&” and the year in parentheses; e.g. “Shmaryan and Deutsch (1999) demonstrated that ….”

    d. When referencing from three to five authors, it is necessary to refer to all the authors the first time they are mentioned; e.g. (Cortez, Jones & Hammond, 1998). In subsequent quotes the name of the first author shall be written followed by the expression “et al.”; e.g. (Cortez et al., 1998). When the authors are part of the sentence, e.g. “…the mechanism was proposed by Cortez, Jones and Hammond (1998)…” in subsequent quotes it shall be “Cortez et al. (1998) studied the advances…”

    e. For six or more authors the last name of the firs author shall always be used followed by the expression et al.; e.g. (Miller et al., 2005) and if the authors are part of the sentence it shall read thus: “demonstrated by Miller et al. (2005) in their research…”

Bibliographical references at the end of the article:

Authors must provide the contact data of four potential reviewers, experts in the topic of the article, and without any link or relationship to the institute to which the authors are affiliated.

The Editorial Board continues the process by verifying the evaluations of the external peer reviewers and sending the responses from authors, requesting also any modification to style which it may consider pertinent, prior to authorizing publication. If the Editorial Board of CT&F has not received response from the authors to the suggestions done for the external reviewers after a period of three weeks, the paper will be remove from the evaluation process.

An article that has been approved by the Board is sent to the authors for approval of the final version. The authors receive a sample of the issue free of cost.
