PFAS in Action
PFAS is used by several companies world wide.
- In the North Sea, on 4th generation rigs.
- In land operations in Texas - USA.
- On barges and rigs in Venezuela under extreme anisotropic stress
- In deep water operations in Angola.
PFAS is used in many different environments - here are some examples of
use in advanced wells.
Training & deep water drilling outside Angola
Before drilling block 34 offshore Angola, ITC trained drilling
engineers from Sonangol for 8 months.
PFAS was use for the planning of the well at 1800 water depth.
The well was drilled in 18 days.
Deepest Wild-cat in the North Sea
One of our North Sea clients, Norsk Hydro, is using Scarabeo 5, a
4th generation DP rig, drilling Wild-cats in deep water (1351 mRKB).
PFAS is used both on the rig and on land, for Planning and Follow-up
of Pore pressure and Well Bore Stability.
This is a new North Sea record due to the combination of deep
water, high waves and strong currents.
Long horizontal completions on the Troll field
With a thin oil-layer, only 10 - 15 metres, and a shallow
reservoir at 1500 mRKB, the need for long horizontal sections is the
basis for developing this field. PFAS is used to Plan and Follow-up
these extreme drilling operations.
Drilling 3 - 4000 metres horizontal sections with geo-stearing
within one meter vertical accuracy, with little integrity,
continuous gain / loss, using Auto Track techonlogy, results in good
economy for the owners.
Transocean Arctic is a 4th generation arctic rig holding the
current world record for cold drilling - 20 degrees C below
Norsk Hydro has been using this rig in the Barent Sea to drill a
Wild-cat this summer, Planning and Follow-up the operations with
The Barent Sea is an enormous area with great potential. Summer
2000 the first oil was found close to and existing gas field.
Drilling with zero integrity on the Snorre Field
Drilling through depleted reservoirs without costly losses, is
now possible because of new methodology through PFAS.
Knowing the current Pore pressure (reservoir pressure), you can
calculate the current stresses, such as Fracture and Collapse. Place
the mud weight on your collapse gradient. Calculating the ECD
accurately. Plan the drilling operation to avoid any pressure pulses
during drilling, by using a pressure sub with your MWD to enable ECD
