Assignment: B CASE STUDY (Attempt all questions. Every question carries 10 marks) Read the case �Southeast Asia Offshore Oil Drilling Problem� and answer the following questions. Southeast Asia Offshore Oil Drilling Problem This case study is part of a series designed to help students and younger engineers develop business problem solving skills through real engineering scenarios. Each case study will provide practical applications of specific, reallife examples to develop the strategy skills that leading companies use to succeed in the marketplace. Scenario Our client, Petro-Oil, is a mid-sized oil and gas exploration and production company with major areas of exploration located in South America, Gulf of Mexico, Western Africa, China, Eastern Europe, and several other countries. The Board of Petro-Oil has just set an ambitious goal to be completed in the next five years: To be the largest oil and gas producer in Asia by the end of 2017. A quick market research inquiry shows three major competitor companies (Table 1) that are larger than our client. To support their new aspirations, our client just purchased Ceylon-II, a large deep-water oilfield offshore in the South China Sea. Table 1: Benchmark Results (million barrels of oil equivalent): Proven Reserves Annual Production Competitor A: PetroChina 15,000 1,500 Competitor B: Petronas 8,000 800 Competitor C: Pertamina 7,500 750 Client: Current Producing Assets 6,000 450 Client: Ceylon-II 6,000 0 Petro-Oil�s management team has hired your company to do a diagnostic of the company�s current portfolio, operations, and organization to help them understand what they need to do to achieve this goal.
