Thanks, Carlos. After the discoveries during the first quarter, both in the onshore with the well Borando-1 and in the offshore with the wells Purple Angel-1 and Gorgon-1, the exploration campaign continued during the second quarter in the offshore with the drilling of well Siluro-1, in block RC-11. Although this well did not encounter any evidence of hydrocarbon, the information obtained will contribute to the general understanding of the Guajira offshore basin. Ecopetrol holds 50% equity in this block, which is operated by the company Repsol. On the other hand, on July 10 the Warrior-2 in the Gulf of Mexico Green Canyon area reached its total depth. The well is operated by Anadarko 70% working interest with Ecopetrol as the only partner with 30% remaining. This well confirmed the presence of hydrocarbons in several zones and is currently being evaluated. In conclusion, as of the first half of the year we have completed four wells of discoveries, a striking success in all our fronts of activity, both on onshore with the well Boranda-1, as in the Colombia offshore with the wells Purple Angel-1 and Gorgon-1, both operated by Anadarko; and in addition, in the Gulf of Mexico we have made a discovery in the well Warrior-2. This gives us so far an operation success rate of near 80%. With these discoveries and as a result of a joint integrated effort, Ecopetrol is expecting to incorporate more than 250 million barrels of oil equivalent of contingent resources, above the expected target set for 2017. Let's move to the next slide. During the second half of the year, the 2017 offshore operations will reach its climax with the drilling of two additional wells, the Brahma-1 and the Molusco-1. And the focus then will be redirected to the projects for the Colombian onshore. On July 9 commenced the drilling of the prospect Brahma-1 in offshore Colombia, which is estimated to drill until the end of September. This well is operated by Petrobras 40% in partnership with Ecopetrol 30%, Repsol 20% and Statoil 10%. By the end of July, on the onshore activities, Ecopetrol and affiliate Hocol spudded two wells, the well Bonifacio-1 and the well Lunera-1 in blocks Lla-65 and in block VSM-9 respectively. In parallel, two seismic acquisition campaigns will commence in the blocks SN8 and SN18. Looking ahead of the rest of 2017, drilling of further nine onshore wells is planned, operated both by Ecopetrol and Hocol. Among others, resuming activities in block CPO-9 with the wells Lorito-1 and Trogon-1 are foreseen for the third quarter of this year. Finally, in line with further strengthening of our international portfolio, Ecopetrol is evaluating a speculative position in the divestment process of Petrobras and in the bid rounds announced by the MEP. In addition, a 3D [ph] acquisition campaign is planned for the Foz do Amazonas Basin blocks. I will hand the floor now to Rafael Guzman, who will comment about the production results.
