Exxon Mobil Work Profiles – An overview

For Promethean ConsultantsBy Nandkumar Nair

The Main Businesses

• Deep water drilling• Exploration• Hydraulic Fracturing• Liquefied Natural Gas• Vehicle Technology

Deep Water Drilling

• Floating Production Storage and Offloading (FPSO) vessel

• It is used for processing Hydrocarbons• Receives Hydrocarbons either from its own

processes or from another platform• After processing it saves the oil till transferred• Transfer to another tanker or via pipelines

FPSO Jobs

• Conversion jobs ie. Projects & Ship jobs• Petrochemical Jobs

Conversion Project

Conversion Project Jobs

• Projects assigned to specific Floating solution consultants

• Some of the leading FPSO companies are– Shell– Maersk– Prosafe– Modec– BW Offshore– Chevron

• The major requirements include– Concept development (Special consultant services)– Design engineering (Only FPSO or FSO depending on

project)– Procurement profiles (large scale project purchase profiles)– Finance profiles (Majorly into Estimation and auditing)– HR profiles (project based)– Commissioning Engineers (as per project)– Safety (on-site & off-site) profiles (experience on ships,

vessels would be preferred)– Mass number Technical hands (welders, draughtsman and

supervisors)

Petrochemical jobs

• Chemical engineers• Piping engineers• Design Engineers• Commissioning engineers• Project engineers• Specialist profiles• Supervisors• Technical hands

Exploration

• Oil & gas bad conductors of electricity• This is a modern technology into oil & gas

exploration• Low frequency electromagnetic waves used

for “remote” mapping.• 25 years of geophysics research – university

and corporate level

Remote Reservoir Resistivity Mapping (R3M)

• Magnetic controlled source Electromagnetic surveying

• Geo-science and seismic data• Advanced computing capabilities made a

breakthrough since 1990s • 3D methods for survey design, acquisition, data

processing, imaging and interpretation• Success in West Africa, Brazil, Colombia and in

Gulf of Mexico

Jobs

• Radiography researchers• Seismographic researchers• Graphic designers• A complete research team• A complete project team

Liquefied Natural Gas• Access was limited as gas had to be supplied via pipe lines from

sources• Liquefaction conceptualized• Extracted gases cooled upto -162 C to be condensed into liquid• Natural gas is classified into three groups

– Non Associated• No oil contact

– Gas cap• Overlying an oil reserve

– Associated gas• Dissolved in the oil

• Natural gas liquefied for easier storage (majorly methane)

• Odorless, colorless, non-toxic and non-corrosive

• Hazards – flammability, vaporization, freezing and asphyxia

The process

LNG Jobs• Research analysts• Chemical engineers• Planning engineers• Site engineers• Port operations engineers• Oil & Gas project engineers (other project profiles)• Construction & Civil engineers• Naval architects• Piping specialists• Supervisors & Technical hands• Design engineers• Commissioning engineers

Hydraulic fracturing

• It is a well stimulation process• Well stimulation – it is a well intervention

process of pumping water and draining hydrocarbons; performed on a gas or oil well to improve its production

• Well intervention – It is performed on a oil or gas well near the end of its productive life

• Literal definition – The technique of fracturing rock by pressurized liquid

• The pumped liquid is called “fracking fluid” which consists mostly of water, sand and a few other proppants (sand & ceramic)

• First experiment in 1947, commercial use since 1950 in USA

HF/Fracking jobs

• India currently has no fracking projects going on, will be roping in a few projects soon

• Requirements in US for fracking encapsulates– Piping experts– Seismographic experts– Radiology experts– Project engineers– CAD designers– Supervisors– Geologists– Process engineers– Hydrocarbon specialist engineers– Mass number of technical hands

Vehicle Technology

• To reduce emission levels• For better economy rates• Hydrogen fuel cell technology• Lighter vehicular parts and tyre liners

Fuel Cell

• A device converting chemical energy to electrical energy by chemical reactions of positively charged Hydrogen ions with oxygen or an oxidized agent

• Tank to wheel efficiency increases by 36% overall• Hydrogen fuel cell (compressed hydrogen)can

store energy like batteries, unlike other fuel cells• Fuel cells are used for power generation at

industrial as well as domestic scale• Used in cars and buses, also started in public trains

Vehicle technology jobs

• Researchers & analysts• Designers• Project engineers & executors• Plastic specialists (preferred from automobile

background)• Hydrocarbon engineers• Automobile engineers• Chemical engineers

Competitors

• British Petroleum• Chevron Corporation• Royal Dutch Shell• Petrochina Corporation• Gazprom Corporation
