1 LATIN AMERICAN DRILLING SAFETY REPAIR & CERTIFICATION OF BLOW OUT PREVENTERS IN ARGENTINA WILFREDO NUÑEZ JORGE GOLDSACK

2 PREAMBLE The essence of Well Integrity is the ability to guarantee the safe containment of pressured subsurface formation fluids during a Well Control. BLOW OUT PREVENTERS are critical to the safety of the Crew, the Environment and the Rig, thus Blowout Preventers are intended to be Fail-Safe Devices. A good repair and maintenance of certified B.O.P.´s is the building block upon which Safety and Well Integrity are founded.

3 TIMELINE Argentinean Custom laws made very difficult to import used or rebuilt parts or tools for the oil industry (Including BOPs). Therefore, the BOPs that need to be exported to be repaired or certified cannot come back to the country; its allowed importing NEW preventers, but it was complicated for used or rebuilt parts. Industrias Petroleras del Sur (IPS) in Neuquen with Cameron license, was the single certified BOP repair workshop in Argentina and they were concentrated in the Drilling BOP segment. IPS had the infrastructure to repair/certify about 8 BOP´s a month. Most of them were Drilling BOP (11 & 13 5/8). Wenlen had the infrastructure to repair it´s own BOP´s as Manufacturer, but in the end of 90´s, the compañy dismantled the whole manufacture and repair line. Shaffer (BOP Manufacturer Company) tried to certify a repair shop, but did not achieve any Tech-Economics deal with any workshop in Argentina. INITIAL SITUATION 2006

4 TIMELINE INITIAL SITUATION: Importation complicated, One Overloaded Workshop, Homemade supplies. 2006

5 TIMELINE THE PROBLEM: The large number of preventers needed to be serviced, urged the contractors to hire improvised workshops and use not original or homemade spares to repair the equipment. There were several incidents in Workover and Pulling Rigs related to BOP´s failures. The situation generated a lack of confidence among operators. 2006 Late 2006 INITIAL SITUATION: Importation complicated, One Overloaded Workshop, Homemade supplies.

6 TIMELINE THE PROBLEM: Incidents regarding BOP´s failures, disappointed operators. 2006 Late 2006 INITIAL SITUATION: Importation complicated, One Overloaded Workshop, Homemade supplies.

7 TIMELINE THE REQUIREMENTS:. Pride International made a presentation at the 2007 Drilling Congress clearing up the situation with the BOP (Drilling, Workover & Pulling) and the urgency ofdeveloping certified workshops to address the problem. There were about 200 BOPs queuing to be repaired Only in WO & Pulling, the market demanded a minimum of 5 BOP repairs a month. IPS capacity was 2 to 2.5. 2006 Late 2006 2007 INITIAL SITUATION: Importation complicated, One Overloaded Workshop, Homemade supplies. THE PROBLEM: Incidents regarding BOP´s failures, disappointed operators.

10 TIMELINE 2006 Late 2006 2007 The situation worsened: In 2008 the oil industry activity dropped and reduced the IPS workload which conducted a reduction in the IPS staff and repair capacity. IPS reduced it capacity from 8 to 6 BOP´s per month, between annulars and rams. Early 2008 INITIAL SITUATION: Importation complicated, One Overloaded Workshop, Homemade supplies. THE PROBLEM: Incidents regarding BOP´s failures, disappointed operators. THE REQUIREMENTS:. A New certified workshop is requiered. Rig Activity Dropped

THE REQUIREMENTS:. A New certified workshop is requiered. Rig Activity Dropped

27 THE FINAL RESULT EVALUATION STAGE After arriving the BOP to the workshop a tag number is assigned and an evaluation check list is performed, involving the related tasks and responsibilities Tasks: Identification of every single piece and valve. Dimensional evaluation; Visual and not- destructive tests, hardness test, Nital. After the BOP is evaluated, the customer receives a budget and a detailed report including,photographic records of the parts to be replaced or repaired. THE REBUILDING PROCESS

28 THE FINAL RESULT EVALUATION STAGE THE REBUILDING PROCESS

29 THE FINAL RESULT REPAIR STAGE Once the client accepts the budget, the repair stage begins. This stage could include Welding filler, heat treatment, forged, etc. The policy of the shop is always to asks the client for new spare parts to repair the BOP THE REBUILDING PROCESS

37 CONCLUSION MOST OF THE BOPS THAT ARRIVES TO THE SHOP ARE IN VERY POOR CONDITION. DAMAGES INCLUDE SHOCKS, CORROSION, EROSION, SCRATCHED SLEEVES & DAMAGES STUDS MOST OF THE DAMAGES ARE MADE BY MISHANDLING, POOR STORAGE CONDITIONS, LACK OF PREVENTIVE MAINTENANCE AND POOR TRAINED PERSONNEL THE VARIABLE THAT DETERMINES THE REPAIR TIME IS THE GENERAL CONDITION OF THE BOP AT ARRIVING. IMPROVING PREVENTIVE MAINTENANCE AND REINFORCING OPERATION PROCEDURES WILL HELP TO REDUCE THE REBUILDING AND CERTIFYING TIME. FACTS
