1. Components of petroleum systems
engineering
An investment company wants to come to
Saskatchewan to invest in the oil and gas
industry. This companys objective is to
become a small/median size oil company with
a daily oil production of 10,000bbl/day. In
order to be successful, what this investment
company should do?
2. Components of petroleum production system
The reservoir
Reservoir fluid
The zone near the well and
well completion
The wellbore
The surface facility

The reservoir Reservoir geology: homogeneous, heterogeneous,
anisotropy, shale, trapping mechanisms.
Porosity
Reservoir net-pay thickness, gross pay thickness
Fluid saturation, So, Sw, Sg
OOIP, Volumetric method
Absolute Permeability, phase permeability and relative permeability
Bottom-water, edge water, gas cap, water-oil contact, gas-oil contact
The Reservoir Fluids
Under-saturated oil reservoir
Saturated oil reservoir

A typical pressure profile
o The pressure drop
around the wellbore is
significant!
o the pressure drop will
be larger if the
formation is damaged!
o matrix acidizing or
fracturing are performed
to reduce the pressure
drop around the
wellbore!
o There have any other problems associated with sandface:
wellbore stability
Sand production
multiple zone isolation!
Therefore, we need technologies to solve those problems.
This is called well completion.
