Vaca Muerta has a fairly triangular shape in which Añelo is located right in the center and the area in which the large deposits have been developed. But towards the nortenear the town of Rincón de los Sauces and on the border with Mendoza, there are a series of blocks that is expanding the productive frontier of shale and they are already having good results.
A recent report by the consulting firm G&G Energy Consultant, led by Daniel Gerold, reviewed the current state of blocks that are heavily focused on oil production with a low amount of associated gas.
Although in the area located regarding 120 kilometers from Añelo there is a block that is in a much more advanced stage, the area Bajo del Choique – La Invernada operated by ExxonMobil, in this case the analysis focuses on the areas that are in the pilot phase, the equivalent of exploration in the conventional one.
The first block to highlight is Narambuena, a sector that still does not have a non-conventional exploitation concession, for which reason it is part of the huge area of conventional Chihuido de la Sierra Negra.
It is a development that is operated by YPF in a 50% partnership with Chevron. There the firms already made six wells bound for Vaca Muerta and in February they reached a production of 900 barrels per day and 100,000 cubic meters of gas.
A little further south is the area The Toldos 2 East that in this case it does have the specific concession and that it is operated by Tecpetrol in partnership with Gas y Petróleo del Neuquén (GyP) in a ratio of 90 and 10% of the assets.
The companies have a total 5 wells to Vaca Muerta, two of which are actually older since they were drilled by Canadian Independent Americas Petrogas. But they also have a new vertical cut well that brought production from the block to the 2,500 barrels per day and a plus of 80,000 cubic meters of gas per day.
A little to the east is another area under study: Moorish Eagle. In this case the block is operated by Vista with 90% of the assets and the remaining 10% in the hands of GyP.
In this block, the oil company led by Miguel Galuccio is operating four wells towards the shale they inherited from Shell and they have two more that are expected to be fractured and put into production before the end of the year.
Right on this block is Bajo del Toro Nortea concession that is operated by YPF and that has Norway as a 50% partner Equinor.
In this area the firms have already carried out 10 wells, of which 2 are intended for water disposal. With these wells, production already reached in February was 1,950 barrels per day and 60,000 cubic meters of gas.
While the map of the northern border of Vaca Muerta is complemented by the area The Eastern Trapial exclusive concession of Chevron where the North American firm has already carried out 13 wells and has 6 of them in production. In February, the block produced a daily production of 1,100 barrels of oil.
The north of Vaca Muerta has the potential to consolidate as a second pole of activity in the shale formation, taking the positive flow of employment to more locations such as Rincón de los Sauces. And also becoming the image to observe for the developments that in a minor stage have just begun to take shape at the other end of the Vaca Muerta triangle, in the southern end closest to Senillosa.
