Abstract

MINDIOLA, Gladys L.; FLORES, Miguel  and  RONDON, Asdruberlis E.. Microorganism enhanced oil recovery (MEOR) technology application feasibility in the Pilon field reservoirs, Morichal District, Monagas State. Ing. compet. [online]. 2021, vol.23, n.2, e20710539.  Epub May 18, 2021. ISSN 0123-3033.  https://doi.org/10.25100/iyc.v23i2.10539.

The present research work arises in relation to the needs of the oil industry to produce those deposits of the Morichal District, possessors of high remaining reserves, where MEOR symbolizes a biotechnological, effective and profitable alternative that uses the injection of microorganisms as an additional strategy to the conventional treatments of improved recovery of hydrocarbons. Different oil fields located in different parts of the world have implemented this process with similar approaches and expectations, however, the results have had discrepancies, since bacteria are significantly affected by variations in subsoil conditions, which is why a methodology was designed to select wells candidates to carry out this technique, which exhibits the most suitable environment for such purposes, coupled with it, certain correlations were established from statistical programs to predict both Water Cut (%) and Recovery Factor (%), which represent important aspects to compare and guarantee how feasible the MEOR process can be in this potentially important area within the oil context, noting that they yielded satisfactory estimates in the wells particularly under study belonging to the Pilon Field, since they affected on average a 38% increase in the recovery factor and an approximate decrease in the water cut of 16% projecting optimistic expectations regarding the success of this process.

Keywords : Bioproducts; Enhanced oil recovery; MEOR; Morichal district.
