Caracterización del Miembro Pilmatué de la Formación Agrio como reservorio no convencional de tipo shale

Abstract

The objective of this work is to characterize the Pilmatué Member of the Formation Sour (late Valanginian – early Hauterivian) in the Chos fossa region Malal, to determine its potential as an unconventional shale-type reservoir. The analyzes carried out on the samples collected in the study locations, in together with the information obtained from hydrocarbon wells from reservoirs nearby, allow us to conclude that the Pilmatué Member of the Formation Sour (late Valanginian – early Hauterivian) in the Chos fossa area Malal, has good geochemical, mineralogical and petrophysical characteristics, allowing it to be considered as a potential unconventional reservoir of the type shale, producer of oil generated from a mainly marine kerogen Type II to II / III. The lower section of the Pilmatué Member of the Agrio Formation shows to have good geochemical conditions to consider a potential thickness of 100 m shale reservoir according to the analyzes carried out on the samples of outcrop and 246 m according to the studies reviewed in the YPF.Nq.FM.x-3 well of the Filo Morado deposit.It is important in the future to expand the analyzes carried out in this work to other areas within the basin region in which the Pilmatué Member of the Formation Agrio is in the oil generation window. Evaluate its characteristics geochemical, petrophysical and mineralogical in different wells and outcrops, in a to delimit possible areas for the economic recovery of hydrocarbon not conventional.
