Exploration is split into three operational areas:Petroleum Production is split into two operational areas:


Subsurface Exploration


Surface Exploration


Aerospace Exploration


Surface Production



Subsurface Production






Exploration drilling

Open-Hole surveys:

Acoustic logging

Vertical seismic profiling

Temperature logging

Gamma density logging

Formation resistivity logging

Neutron logging

Formation testing

Cased-Hole surveys:

Pressure testing

Laboratory analysis: survey

Core analysis

PVT analysis

Outcrops Climate survey
Climate

Infrared Imaging

Production gathering


Fluid injection


Fluid supply

Well & Reservoir Management


Reservoir Study & Modelling


Well & Reservoir Surveillance





The results of the exploration lead to the procedure of Booking Reserves


Routine production operations usually follow a specific production strategy which is a part of Field Development Planning
