This YPFB press release was published using an automatic translation system.

The application of technologies such as Seismic Acquisition, Seismic Reprocessing, Seismic Characterization, Geochemistry and Surface Geomicrobiology, Magnetoteluric and other studies, allow estimating that the Plurinational State of Bolivia currently has more than 130 trillion cubic feet (TCF) of natural gas.

"With the application of these technologies and studies we can say today with solvency that we have more than 130 TCF as prospective resources at the level of yet to find in Bolivia (...) The next step that YPFB is giving is to improve studies for reduce uncertainty and identify prospects, "said the vice president of Administration, Contracts and Control of YPFB, Luis Alberto Poma, during the panel" New technologies, efficiency and standardization of operations in the exploration and exploitation of hydrocarbons ", which was developed in the First International Forum of Gas, Petrochemical and Green Fuels Bolivia 2018.

The application of these technologies allowed the evaluation of the potentials in all the basins at a national level, "it is the work that has been carried out we would say for the first time in an integral way, today we have with the application of these technologies an integral study in everything that is area of ​​oil interest ", complemented Poma. In the Subandino Sur and Pie de Monte we estimate to have 74 TCF, in Madre de Dios 12 TCF, in the Subandino Norte and Beniana Plain we estimate to have at least 15 TCF, in Boomerang and Pie de Monte Norte 16.2 TCF, in the Chaco Plain 15 TCF and the Altiplano 4 TCF.

Among the geophysical methods used by YPFB, we can mention the seismic acquisition that consists of the generation and recording of reflection waves that cross the strata with different seismic responses, the same ones that return to the surface to be registered as seismic data. "This allows us to determine the structural configuration of the subsoil and determine the possible traps where the hydrocarbons can lodge," Poma explained.

Seismic Reprocessing This method allows to improve the seismic image in order to define with less uncertainty the geometry of the trap. The Seismic Characterization allows to infer the physical properties of the rock from the seismic data related to geological information by means of statistical techniques. "We use this method to identify the main reservoirs from the discrimination of rock types and fluids," stressed Poma.

The method of Geochemistry and Surface Geomicrobiology . This method is used to identify areas potentially with significant accumulations of hydrocarbons in the subsoil. Identifies microbial anomalies and gases absorbed in soil sediments.

The Magnetotelúrica completes the seismic works and detects the special variation of the resistivity of the subsoil layers by measuring the electric and magnetic fields on the surface.

"In Bolivia with all these methods we have developed many projects from the Madre de Dios Basin, the Chaco Basin, the Subandino Basin making seismic, magnetotelluric gravimetry and others that have allowed us to determine potential in all our basins.

It is all the information we have in our database that throughout these years YPFB has been working with the application of these technologies.

The moderator of the panel, the president of YPFB, Óscar Barriga Arteaga highlighted the scenario reported by the vice president of the state oil company and concluded that the prospective resources of 130 TCF to be discovered represents a challenge for YPFB.

Barriga indicated that the behavior of the price of oil motivated the implementation of new technologies that allow to reduce costs, time and standardize the operations to reduce the risk in a context where the technical restrictions of security and environment are increasing, always protecting the impacts to the environment.

"Bolivia has entered into an exploratory scenario that opens new objectives of interest at greater depth in the lower blocks, for which it is essential to ensure that operations adapt to the conditions of pressure and temperature that can be found at these levels. greater than 7,000 meters puts us one yard higher than normal and demands that the industry be prepared to face this type of project ", highlighted Barriga.
