OGX Reports Operational Reports for 2010
OGX announced its 2010 results. The following financial and operating information is presented on a consolidated basis, in accordance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board - IASB, in reais (R$), unless stated otherwise.
"2010 was a year of tremendous achievements for OGX. Our drilling success and identification of extraordinary accumulations in the Campos, Santos and Parnaiba basins validated the geological models developed by our team, revealed the significant potential of our portfolio located mostly in shallow waters, and encouraged the mapping of additional prospects. With 9 drilling rigs now at our disposal, we are also prepared to enter another exploratory cycle in under-explored basins, such as the Espirito Santo and Para-Maranhão, as well as commence seismic studies in five recently-acquired blocks in Colombia," commented Mr. Paulo Mendonça, OGX's General Executive Officer.
"In particular, I would like to highlight our accomplishments in the Campos Basin, where we achieved a success rate of 100% and registered excellent discoveries, most of them located in an extensive carbonate platform, which had its production potential proved through one of the best horizontal well drill-stem tests ever performed in Brazil," added Mr. Mendonça.
"With all necessary equipment already procured from renowned suppliers, the drilling of the first production well and related drill-stem test both completed, we are on track and poised to reach a very important milestone for OGX with the initiation of production in the third quarter of 2011. The successful horizontal well drill-stem test recently performed in Waimea, where we will begin our production, surpassed our expectations. We look forward to conducting the upcoming extended well test, which signals the beginning of production and, ultimately, commercialization of our resources," noted Reinaldo Belotti, Production Officer of OGX.
2010 Highlights and Subsequent Events
- Drilling of 26 wells during the year of 2010 and 11 in the subsequent months in the Campos, Santos and Parnaíba Basins;
- Confirmed the existence of important oil-bearing regions in the Campos basin: an extensive carbonate platform in the Albian section, as well as important sandstone reservoirs in the Tertiary of the BM-C-41, BM-C-42 and BM-C-43 blocks in the south of the Campos Basin, and another one in BM-C-39 and BM-C-40 blocks, more to the north, with large discoveries in the Santonian, Albian and Albian-Cenomanian sections;
- Performed several drill-stem tests, proving high levels of productivity in several discovered accumulations;
- Concluded the drilling of the first horizontal well (OGX-26HP) of the Waimea accumulation, which tested and confirmed the productive potential of 40,000 barrels per day and productivity index of 100m³/day/kgf/cm² in carbonate reservoirs in the Campos Basin. OGX's production phase will commence at this well through an extended well test (EWT);
- Three discoveries in the Santos Basin, with the identification of liquid hydrocarbons and associated gas;
- Revealed the great hydrocarbon-bearing potential in the Parnaíba Basin with the results obtained in the drilling of the wells OGX-16 and OGX-22, allowing for a volume estimate of potential resources of approximately 15 trillion cubic feet (Tcf) of natural gas in the region;
- Acquired five high-potential exploratory blocks in three onshore basins in Colombia: Cesar-Ranchería, Lower Magdalena Valley and Middle Magdalena Valley Basins;
- Procured all of the essential equipment for beginning production in the Waimea accumulation in the Campos Basin.
2010 was a year of extraordinary accomplishments and major achievements for OGX, notable for significant discoveries and the confirmation of the high productivity potential of our main hydrocarbon accumulations. We intensified our exploratory campaign and conducted important drill-stem tests that confirmed the Company's geological model and the potential of the discoveries we have made. These tests yielded fundamental information that provided for a better understanding of the reservoirs that had been discovered in the Campos Basin, allowing us to further enhance the calibration of the production model to be put into place.
At the moment we are drilling the 39th well of OGX, which added to the four other wells drilled by Maersk Oil, bring the total number of wells drilled in the Campos, Santos and Parnaíba Basins to 43 in approximately 18 months since the beginning of our exploratory campaign. Of the 43 total wells, 26 were drilled in 2010, demonstrating the intensification of our activities, and resulting in important discoveries, some of them in areas that until now had been under-explored, including the Parnaíba onshore basin in the interior of the state of Maranhão. These results were made possible due to both a more robust operating structure and the superior geological knowledge that has been acquired about the region. We expanded the number of available drilling rigs from four to nine and now have nearly 5,000 people working on our behalf including outsourced personnel.
We ended 2010 with 18 wells drilled in the Campos Basin, all of which identified hydrocarbons, confirming a success rate of 100% in this basin. Of this total, 11 were drilled in the BM-C-41, BM-C-42 and BM-C-43 blocks and allowed for the identification of several accumulations in different geological ages, confirming the presence of a vast oil-bearing province in these blocks. Through the wells OGX-2A, OGX-3, OGX-5, OGX-6, OGX-7A, OGX-8, OGX-10, OGX-15, OGX-20, OGX-21D, OGX-26HP, OGX-28, as well as the MRK-3/4 wells, we have also confirmed the existence of an extensive carbonate platform in the Albian section with great permo-porosity conditions and good quality oil. Moreover, we recorded important discoveries in the Tertiary age and in the Aptian section, reaffirming the enormous potential of the region.
We also began our drilling activities in the blocks BM-C-39 and BM-C-40, located between the Peregrino and Polvo fields, and have obtained excellent results, especially with the OGX-14 (Peró), OGX-18 (Ingá) and OGX-25 (Waikiki) wells. For OGX-14 and OGX-18, drill-stem tests were performed which identified production potential of 3,000 barrels/day using a vertical well for the Peró accumulation that could reach 15,000 barrels/day using a horizontal well, and 8,000 to 12,000 barrels/day through a vertical well at the Ingá accumulation that could reach 25,000-35,000 barrels/day through a horizontal well. The tests also enabled us to measure the quality of the oil at approximately 27° API in each accumulation. Well OGX-25, also known as Waikiki, was an exceptional discovery with the largest detected net pay of approximately 145 meters in the Albian-Cenomanian section.
In addition to the exploratory wells, the first appraisal well for the Waimea accumulation, OGX‐21D (BM-C-41 block) was drilled. It was converted into a horizontal well, OGX-26HP, which extended 1,000 meters within the carbonate reservoirs of the Albian section of the Waimea accumulation, originally discovered by well OGX‐3. The well OGX-26HP, which will be OGX's first production well, was tested and registered a productivity index (PI) of 100m³/day/kgf/cm², one of the highest seen to date in Brazil, as well as a production potential of 40,000 barrels/day and oil gravity of approximately 20° API. This well is currently equipped for an extended well test (EWT) that could record flows of up to 20,000 barrels/day and reach even higher flow levels in a definitive project scenario. The results to date have exceeded initial expectations regarding the Waimea accumulation and offer an even more solid foundation for the initiation of OGX's production phase.
Besides this, two other appraisal wells in the Pipeline (OGX-36D) and Waikiki (OGX-35D) accumulations confirmed their extensions, advancing significantly the delineation of these accumulations, which are respectively located in the southern and northern blocks of the Campos Basin. These directional wells, which were drilled at respective distances of 2.6km and 2.0 km from the wildcat wells, were the pilots for the horizontal wells in these accumulations. Therefore, OGX initiated the drilling of the first horizontal well in the Pipeline accumulation (OGX-39HP) which will be used in the future for production in this area.
With respect to the Santos Basin, of particular note was the drilling in the Natal prospect (OGX-11D) in the BM-S-59 block adjacent to the Mexilhão field, which identified liquid hydrocarbons and associated gas in the Santonian section with net pay of around 75 meters. The liquid hydrocarbons proved to be of excellent quality, rated at about 41° API, indicating a higher level of attractiveness of the project. Two other wells registered important discoveries: Belém (OGX-17, with net pay of 43 meters in the Albian section), located in the BM-S-56 block; and Aracajú (OGX-19, with net pay of 40 meters in the Santonian section), located in the BM-S-58 block.
Drilling of the OGX-12 (Niterói), OGX-23 (Ilhéus) and OGX-24 (Itagi) wells has been concluded and resulted in shows of non-commercial hydrocarbons. However, the information acquired through these wells has been of great importance in the calibration of a new geological model for the region. In addition, with the transfer of exploratory rights of the BM-S-29 block from Maersk to OGX, the Company now owns 100% of this block, which is in the evaluation phase. To date, the company's success rate in the Santos Basin has been approximately 60%.
In the Parnaíba Basin, the Company's subsidiary OGX Maranhão, drilled two wells in the PN-T-68 block, reaffirming the great oil-bearing potential of this new frontier which had not been explored since the 1980s. In the first well, OGX-16 (Califórnia), an important gas discovery was made in the Devonian section with a drill-stem test that encountered 1,900-psi pressure and generated a flame 15 meters long. In addition, evidence of gas was also encountered in the Pimenteiras and Itaim formations, also in the Devonian section. The data obtained through this drilling campaign, coupled with the seismic information recently acquired in the area as well as technical analysis, have made it possible to identify approximately 20 prospects similar to the one drilled by OGX-16 and to estimate a volume of resources of approximately 15 trillion cubic feet (Tcf) of natural gas for our portfolio in this region. In the second well, OGX-22 (Fazenda São José), two accumulations were found with net pay of 49 and 47 meters in the Poti and Cabeças formations, respectively. The top of the Poti formation was tested with exceptional results which indicated a production potential of up to 3.4 million m³ per day in Absolute Open Flow (AOF).
These estimates point to a production potential for the region of approximately 15 million cubic meters per day of natural gas. Based on this relevant new data, OGX decided to review the scope of its exploratory campaign for the region and boosted the forecast for the number of wells to be drilled from 7 to 15.

Beginning of Production
The beginning of OGX's production is expected for the third quarter of 2011. This will be an important milestone in the Company's history and will contribute to its ongoing growth trajectory in the coming years. The production will be in the Waimea accumulation, in block BM-C-41 in the Campos Basin, through an extended well test (EWT), which could record flows of up to 20,000 barrels/day.
The technology that will be employed for this first project has been widely applied within the oil industry and calls for using wet christmas trees and flexible lines that will be directly connected to the FPSO OSX-1. The well was prepared for production using the subsea centrifugal pumping method.
All of the key equipment for this phase of production has already been contracted from globally renowned suppliers and some pieces have already been delivered. Suppliers of equipment and services include: Schlumberger (Integrated Project Management and equipment and services for well completion), GE Oil & Gas (subsea X-trees), Wellstream (flexible lines and a vessel for launching the lines), Oceaneering (control umbilical), Baker Hughes (electrical subsea pumping) and OSX, which will supply the FPSO OSX-1. This FPSO (Floating Production Storage & Offloading system) is currently in Singapore, undergoing modifications to its processing plant in order to conform to the characteristics of the Waimea oil and is expected to arrive in Brazil by mid 2011.
