A petroleum
engineer is one who has studied petroleum engineering. This is an engineering
field concerned with all activities in hydrocarbon production. Hydrocarbons in
this case include crude oil or natural gas. Petroleum engineering aims at
maximising recovery of hydrocarbons economicaly from subsurface reservoirs.
However, the recovery of hydrocarbons involves the following steps.
- Exploration
- Development
- Production
The processes
involved in hydrocarbon recovery are interdisciplinary as they include;
- The geologists and geophysicists, (who perform the
static description of the reservoir rock by analysis of subsurface structures
using geological and geophysical methods),
- The reservoir engineer, whose aim is to optimise
production of oil and gas through, proper well placement, models the
productivity of the reservoir and predicts the reservoir potential with the aid
of computer simulation software,
- Petroleum
engineers who estimate the recoverable volume by utilising their understanding
of the physical properties and behaviour of oil, water and gas within the
reservoir.
- Production engineers - who manage the interface
between the reservoir and the well through such tasks as perforations, sand
control, artificial lift, downhole flow control and downhole monitoring
equipment.
- Drilling engineers: who manage the technical
aspects of drilling both production and injection wells. They work in
multidisciplinary teams alongside other engineers, scientists, drilling teams
and contractors.
- Facilities Engineers who ensure proper selection
and design of surface equipments used in separation of the produced fluids (oil,
gas and water).
The petroleum
engineer is involved in nearly all the stages of exploration, development and
production. They are charged with the task of economical hydrocarbon recovery
with minimal environmental impact. The petroleum Engineer requires to also have
a relatively good knowledge of other related disciplines such as petroleum
geology, geophysics, well logging, drilling, field development economics,
reservoir simulation and engineering, well engineering, artificial lift
systems, completions and facilities engineering. However, the combined efforts
of geologists and petroleum engineers helps in determining the way a reservoir
is to be developed and depleted.
