A 3D study of the CO2 naturally stocked: the case of Minero-Florida block in the Sabinas basin, north of Mexico

 abstract = { We present a method to calculate the 3D distribution of CO2 formed and/or stocked
in the block Minero-Florida (MF) of the Sabinas basin. This basin is located in the
northern part of Mexico, 180 km from the border with the USA. It is a basin producer of
natural CH4 gas which contains more than 5km of Mesozoic sedimentary rocks
deposited in a marine environment. The construction of the spatial distribution maps of
CO2 is supported by the 3D seismic interpretation of the block MF and its interpretation
as a 3D structural model built with GOCAD geomodeling software. CO2 data consist of
punctual measurements in five wells, geochemical model results and of the CO2
resulting from the tests carried out on geochemistry and petrographic characterization
of rocks from various sedimentary formations and their fluids. The CO2 and CH4
volumetric maps were generated as: a) in-situ gas analysis, b) obtained by artificial
maturation laboratory, c) generated from the theorical Van Krevelen, d) resulting from
the sample analysis on Rock-Eval pyrolysis, e) calculated with geochemical Petromod
software. Results we also conducted an assessment of the best exploitation location to
drill to new wells in the area, considering the CO2 associated with the CH4. This work
will support meaningfully the decision-making of exploration of geochemical
engineering, in view of the location of future drilling of wells. Our methodology can be
adapted also to other areas of oil exploration. },
