Thank you. Thank you very much Ignacio. Total hydrocarbon production reached 130,000 barrels of oil equivalent per day this quarter. Remaining stable vis-à-vis a year ago and increasing by 2% versus last quarter. Let's look at this in more detail. Crude oil production amounted to 227,000 barrels of fall per day which represents a 1% increase on a quarter-over-quarter basis and remained flat compared to last year's third quarter. But it have been also higher, if we exclude the production associated to the mature fields divestment performed by the end of 2018. Gas production amounted to 44 million cubic meters per day representing a 9% increase quarter-over-quarter mainly driven by higher winter demand and remained flat compared to last year's third quarter. Finally NGL production increased 6% to a total of 28500 barrels per day when compared with 2018 third quarter. When we break down the sources of our total production we can observe that shale production growth contributed with 44.4 additional BOEs per day. And the good news is that this growth by itself is offset in both the conventional production decline and the tight production decline is that one mainly related to a redirection of investment from gas to oil due to the current gas market project. Fueled by the shale production growth, our unconventional production represents now 35% of our total production. I will come back to that in a few moments. But first we would like to highlight few elements of what we have been doing on the conventional side that still represents 65% of our production. Specifically in the conventional side, we remain focused in continuing identifying new fields for primary development, in improving our secondary recovery results by increasing the amount and the quantity of water injected and based on the positive results of the polymer injection pilot and expansion of dispersion recovery technique into other fields in order to improve the recovery fund. Just to mention a few examples of new primary developments, we can mention the Llancanelo carry over field in Mendoza province, where after agreeing a royalties reduction scheme with the province we are able to FID the first ever field development in the country using low-cost multilateral wells with five horizontal brands. We have successfully drilled one of those wells are currently drilling a second one and plan to drill up to 15 of them dramatically reducing the surface footprint of this development from 75 to just 15 locations. In addition, shale oil will be used for blending purposes with a much lighter oil in our Luján de Cuyo Refinery. Also even those are province after successful exploration and first elimination campaign, we are currently finishing a second delineation campaign in the Cerro Morales field with positive results and producing around $1,300 barrels of ore per day during this early stage. We will be testing a water injection scheme during the next 12 months to then define the best way forward. With the current understanding a potential field development plan would include more than 200 producing wells and 100 injectors and increased current production by 10 times or even more if the polymer injection team is positively tested. In the secondary recovery area, we continue identifying opportunities in mature fields which sounds not properly treated by water injection. For example, intuitional [indiscernible] located in new can province and would used to be one of our main producing areas by the end of this month withstanding low-cost water injection was to increase the oil production recovery of this field. We have mentioned in the past the positive results achieved with the tertiary recovery pilots into gold province we are increasing the number of poly manufacturing plants. In addition, we have also achieved positive results in Mendoza province. Finally, we continue with our exploration efforts aiming to discover new resources and new plays. We are glad to announce that we have recently reached an agreement with Equinor the Norwegian major by which they will come in into our can 100 deep exploration block purchasing a 50% stake with a cash and carry consideration. We are happy to join forces with international renowned deep offshore operator in order to explore this potentially prolific Atlantic margin block. Additionally, we have received expression of interest from other top international companies and are therefore jointly launching a second format with the idea of retaining each one a third of the share. Moving now to unconventionals. Our net production in the third quarter of the year surpassed for the first time the 100,000 BOE per day milestone reaching 102,000 BOE per day which is a 77% increase compared to a year ago and a 25% increase quarter-over-quarter. Net shale oil production showed an increase of 55% compared to the third quarter of last year. Shale oil represents now 16% of our total crude oil production. During the quarter, we connected a total of 32 new shale horizontal wells and used 18 renovate. Our operation is mainly focused in the three shale developments, Loma Campana, La Amarga Chica and Bandurria Sur have also in continued risk in our exploration acreage in order to grow and mature the future development portfolio. In Loma Campana the 50-50 JV with Chevron, we have six trillion rigs working gross production reached 42,000 barrels of oil per day and for the first nine months of the year we have added 20 new wells. In La Amarga Chica the 50-50 JV with Petronas we have seven drilling rigs gross production reached 12,000 barrels for per day and we added 12 new wells in the first nine months of the year. In Bandurria Sur, the JV with Schlumberger we have four billion rigs. Gross production reached 5,000 barrels of oil per day. And in the last days we have connected a new four wells. We also continue with exploration and derisking activity in our shale acreage. On the right hand side of the slide we can see the sustained productivity improvements achieved year-on-year in all of our main shale up developments and also a few of the very promising results we are achieving within the risking campaign. For example Bajo del Toro block the JV with Equinor where after successfully put in two horizontal wells into production with very good productivity results. We are planning to drill four more wells in order to have enough information to define new shallow development plan there or for instance Vaca Muerta Loma Campana with three months of outstanding production results. We continue searching to improve efficiency and profitability. As we can see here the development cost and OpEx in Loma Campana is remarkably low. As of today, three additional rigs of those under contract have been upgraded to high spec to allow drilling faster and longer horizontal wells. We have already drilled 3,400 meters of horizontal length well in Banduria Sur and are currently drilling our 4,000 meter one. On the completion side we are switching to high-density completion with an average of 60 meter separation between stages in order to improve productivity. All the wells connected is portal have more frac stages. Moreover, we keep on analyzing the use of nearby plant to continue reducing costs. As a result of these metrics, we continue improving our breakeven in [indiscernible] that is now in the lower end of the $35 to $40 per barrel. Our focus is to keep working on the development cost both in drilling and completion, while improving our operating expense metrics. Whereas we do not control oil and gas prices, we do control our breakeven and therefore our main focus is remaining the most profitable shale operator of the basin and the Partner of Choice. Now, let's look into more detail the gas market and production. On the left hand side of the slide, we can see that we have managed keeping a flat production during the third quarter of this year compared with the third quarter last year. And that we have managed coming back again to our historical production levels. However, we can also see that fueled by the excellent results obtained with the Vaca Muerta shale gas developments. We have now a new reality in the gas market which can be summarized as having more gas offer than demand outside of the provision system, which has already led to gas attainments and tensions in price. We have been mentioning in previous communications all the levers that we have activated to cope with this new reality, I would like now to provide some updates. First, as we already mentioned and supported by the optionality of our shale acreage, we redirected investments originally planned to gas field towards oil field. We have also started exporting gas from Chile this year and are actively looking to increase our share of gas export in the future as there are still availability in the existing infrastructure. We started the construction of a new underground gas storage project that will be functioning in 2020 and will allow us to better cope with the summer and winter swing, therefore reducing procurement. I will be exporting in our first LNG cargo ever before in the next phase from our TANGO floating LNG unit. While we also continue working towards finding a long-term solution to further increase gas demand, which is a sizable LNG terminal. Finally, we have requested offers for the expansion of the preferred to urea plant capacity, a JV will have the new terms and we will be evaluating those offers and the market conditions during the first half of next year. The dynamic in the natural gas market together with an increased supply have put pressure on prices. The gas realization price for this quarter was $4 per million BTU compared with $4.5 one year ago. Nonetheless by the end of the quarter, the price was closer to $3.50 per million BTU. Moving down to our Downstream business segment. During the third quarter of 2019, the utilization rate of our refineries increased 2.6% versus the third quarter of 2018 reaching a total of 297,000 barrels of crude oil processed per day and 90% refinery professional. Regarding sales total volumes remained fairly stable compared to the same period a year ago as lower volumes in the local market were partially offset by higher exports. Indeed total volumes in the local market decreased by 2% driven by lower demand for our main products diesel and gasoline. Moving deeper in the analysis, gasoline sales reported a 2% decreased compared to last year driven by a lower demand for our premium gasoline with a decline of 9% in volumes partially offset by higher volumes of regular gasoline. Diesel sales decreased 6% compared to the third quarter of 2018 driven by lower demand of both regular and premium products with a later drop in 5% compared to last year. I would aggregate market share during the quarter slightly dropped, but remained strong at 56% in line with historic levels. In particular market share for our premium products Infinia gasoline and Infinia diesel remained above 60%. Downstream adjusted EBITDA verifying barrel for the first nine months of the year reached $11 per barrel slightly above last year levels, but still below previous year's figures. Price for gasoline and diesel were reduced in dollar terms due to the freezing prices and the devaluation of the pesos. This was in part offset by higher volumes process and lower cost mainly driven by lower crude oil purchases. Reducing propriety of the reference where local prices should converge. The dotted line shows the evolution of import parity and the full line represents the evolution of the blended price of our fuels in pesos in the beginning of the year 2018. The graph shows that at the beginning of the quarter we were able to close the gap within import parity. However after primary presidential elections with the devaluation of the peso and weaker demand, our blended price went below import parity and in August 16 decreased by six gross fuel prices for a 90-day period. Since then the industry engaged with the government to smooth the path to the maturity of the restriction period. Firstly, we obtain legalization of the wholesale prices which allow us to gradually adjust prices on that segment. Afterwards, in September and November the government allowed to increase the prices at the pump by 4% and 5%, respectively totalizing a 9% increase since the mission was put in place. But still our prices have remained below in propriety with a 15% to 20% gas. Once the 90-day period expire, we expect to continue performing price adjustments to gradually close the gap with fuel price. Complementing what we have shown concerning the gap of our fuel prices when compared with [indiscernible], the following chart shows that the local fuel prices at the pump in U.S. dollars are currently at low historical levels. With this, I will ask Daniel to continue with some closing remarks.
Daniel González: Well, thank you very much, Sergio. In summary, despite the macro situation we performed well and managed to generate a considerable amount of free cash flow from operations necessary to maintain our financial discipline and keep on investing to develop our Vaca Muerta. We are seeing good results in the shale production and our effort will be on improving productivity while continue to reduce costs in the play. We remain focused on accelerating our shale oil developments and will concentrate our investments in the three core shale oil areas; Loma Campana, La Amarga Chica and Bandurria Sur. On the gas side, we will continue to limit our investments until we see we can allocate every molecule of gas we can produce at competitive prices. In the meantime, the objective is to protect our share in the local market, minimize the curtailment and continue to increase exports. As said, we view the freezing prices as a temporary measure that government has taken. Fuel prices are currently at historic lows and we believe in a gradual recovery that allows the continued investment that this sector needs. With recent developments, we are providing new guidance for the rest of the year. We expect EBITDA in the $3.7 billion area, CapEx of approximately $3.2 billion, production decline in the 3% area and net leverage in the 2.15 times area. We believe long-term growth is not being affected by the events of the last few months as Vaca Muerta continues to be a priority not only for us and the rest of the industry, but also for the recently elected government. We may see a little growth in 2020, as we are putting together a plan for next year with a priority in maintaining our sound balance sheet is the only way to assure that long-term vision growth. With that we would like to address your questions. Thank you.
