Covering an area of 64,000 acres, the Carbonera Block is located in the Catatumbo Basin, which constitutes an extension of the highly prolific Lake Maracaibo Basin of Venezuela.
Well logs indicate the presence of hydrocarbons in several horizons and the top of the Mito Juan sandstones was found at a depth of 542ft, with petrophysical evidence showing 5ft of net pay zone.
The top of the Upper and Lower Catatumbo sandstones was found at depths of 452ft and 1,030ft, with petrophysical evidence showing 22ft and 32ft of net pay zone, respectively.
Both formations, with a total vertical oil column of 59ft, represent new discoveries within the Carbonera Block.
Pajarito-1X was tested using a wire-line pump, producing 14 barrels of 41 degrees API oil in 20 hours and is the first well to be tested in the Upper Cretaceous and Tertiary sands, showing good petrophysical characteristics: porosity of 15%, water cut of 34% and 41 degrees API oil in the Mito Juan Formation.
Correlation of this well with seismic and petro-physical information in the surroundings suggests a significant areal extension that, if confirmed, could translate into the immediate design of an appraisal campaign.
With the drilling of Pajarito-1X, Alange has taken the first step to continue exploration in the Upper Cretaceous and Tertiary sandstones in the Carbonera Block, and the company holds a 96% working interest in the block.
