Petroleum industry

? The petroleum industry has evolved over the years to become a gigantic industry. ? Personnel in the areas of sciences & applied sciences are required: • Petroleum engineers • Mechanical engineers • Chemical engineers • Electrical engineers • Computer scientists • Physicists • Chemists • Marine biologists & • Geologists engineers • Others ? There 2 broad classifications of global petroleum industry: • National Oil Companies (NOC) • International Oil Companies (IOC) ? Very large in terms of production, & some substantial in refining. ? They are owned by their respective governments. ?

They account for about 33. 33% of world crude production. ? Examples of NOCs: • Petronas (Malaysia) • Petroleos de Venezuela – PDVSA (Venezuela) • Saudi Aramco (Saudi Arabia) • Statoil Hydro (Norway) • Petrobras (Brazil) • PEMEX (Mexico) • NNPC (Nigeria) • Sinopec, CNOOC (China) • GNPC (Ghana) ? Also known as Multinationals. ? They have a significant proportion of their operations in several different countries. ? There are 5 major IOCs: • British Petroleum (BP) • ChevronTexaco • ExxonMobil • Royal Dutch/Shell (simply Shell) • TotalFinaElf (simply Total)

? Strength of the “Big Five”: • Production in more than 15 countries. • Refining in more than 15 countries. • Products marketing in more than 40 countries. • They account for approx. 13% of world production. • They account for 21% world refining. • They account for 35% world product sales. ? Other IOCs are: • Amerada Hess • Anadarko • ConocoPhillips (simply Phillips) • ENI/Agip • Kerr McGee • Occidental • Repsol • Unocal ? The 2 main sectors in the industry are: ? Upstream Sector • Producing • Servicing ? Downstream Sector • Refining • Products sales • Transportation

? Basically involves the extraction & field treatment of oil & gas. ? There are 2 divisions: • Research & Development (R&D) • Exploration & Production (E&P) ? Research & Development (R&D) • Scientific inquiry to discover facts, new or better methodology & technology. ? Exploration & Production (E&P) • Field operations where petroleum deposits are being searched for and then produced. ? In the Upstream sector, there are 2 types of industry: • Producing Companies • Servicing Companies ? “Officially” recognized to be directly involved in petroleum exploitation.

? They are given permissions by the host country to operate within a carved out areas called Blocks. ? Examples: ExxonMobil, Chevron, NPDC, Petrobras, Statoil, Saudi Aramco, Royal Dutch Shell, Total, etc. ? “Officially” recognized to be indirectly involved in petroleum exploitation. ? They provide sales & services to producing companies in terms of personnel, research, technology, field operations, and tools & equipment. ? Examples: Transocean, Halliburton, Pride International, Schlumberger, BJ Services, Weatherford, Baker Hughes, etc. ? Itinvolves refining, transportation, storage &marketing of petroleum products. ?

After the initial field treatment of petroleum (separation of gas, oil & water), it is transported to the refinery by truck, train, ship, or pipeline. ? The basic refining tool is Distillation. ? Thermal cracking is used to increase the yield from distillation by subjecting the heavy crude oil to intense heat. ? Alkylation involves recombination of small molecules produced by thermal cracking in the presence of a catalyst. ? Catalytic cracking involves crude oil being cracked in the presence of a finely divided catalyst.
