Vilje, PL036, was discovered in September 2003. Partners are Hydro (28%),
Marathon (46%) and Total E&P Norge (24%). Gas was expected, but
surprisingly oil was discovered. The discovery led to a fast track
development where a PDO (plan for development and operation) was delivered
December 2004. Production will be tied up to Marathons production from
Alvheim, starting February 2007. Hydro will be the operator of the field.
This presentation shows how petrophysical and geological data are
integrated to create geological models and illustrates many of the
uncertainties and choices that needs to be handled in a fast development
plan with limited data available.
Since January 2005 a project team has worked on well planning. After
receiving SCAL data, the petrophysical interpretation was updated. A new
permeability model and SCAL based water saturation model (height/
J-function) was also created. This was imported to RMS and modeled into 4
different geological models, representing different (extreme) scenarios.
The aim is to create robustness as to optimal placement of production
wells. The drilling campaign will start in the autumn of 2006. With a new
pilot we are hoping to get important answers, not only about top reservoir
and geological interpretation, but also concerning a complex transition
zone (OWC/FWL), and tight / sealing faults in the reservoir.
Ingrid is presently working as an advisor in petrophysics for Norsk Hydro
ASA. She has previously worked as a wireline open hole logging field
engineer with Schlumberger in Indonesia and in Ijmuiden, the Netherlands.
Before that she worked in the section for reservoir evaluation with Saga
Petroleum, Norway. Her basic university education (MSc) was at the
Norwegian University of Science and Technology (NTNU / NTH), faculty of
Applied earth science, petroleum geology (geology, geophysics and
petrophysics), the final year being at the University of Texas, Austin.
Ingrid also holds a thesis from NTNU titled "Elemental Capture
Spectroscopy (ECS) - a new geochemical logging tool applied in a deeply
buried sandstone reservoir".
