Mist Mountain Project

• 12 TCF OGIP (BCG) enough gas to supply the
  lower mainland with heat for gt40 yrs
• BP will conduct three to five years of appraisal
  activity before making a decision on commercial
  and environmental viability
• Progress a variety of geoscience and subsurface
  related studies to enhance our understanding of
  the system
• Integrated subsurface work incorporated into a 3D
  model

formations

• HRAM interpretation incorporates
• Structural elements from surface geology
  (Lawrence map)
• Strike-slip lineaments associated with
  reactivation of regional proterozoic structures
• Basin specific thrusts and tear faults

Based on results of interpretation Crowsnest coal
field could be differentiated into regions based
on faulting intensity and structural style

Why is a 3D Model Important?

• Successful drilling prognosis
• Understood bed orientations for efficient
  completions
• Bulk rock volumes for reservoir volumetrics
• Stochastic modelling of facies data
• Predict coal characteristics
• Specifically coal properties that may be
  affected by structure (i.e. sheared coal)

• Collection of mine/field samples
• Appraisal drilling
• Seismic
• Production testing
• Simulation
• Stratigraphy

Conclusions

• The intensity of CBM resources makes it a
  material exploration target
• The Kootenay trend is a significant resource,
  Mist Mountain is a 12 TCF prospect
• HRAM is an instrumental data set in refining and
  validating the 3D structural framework for Mist
  Mountain
• A 3D model adds significant insight for the
  prediction and differentiation of coals
• Sheared coals are more complex than the
  traditional binary system and the level of
  shearing is a continuum of characteristics
• There is continuing research on the possible
  influencing factors that may dictate the level of
  shearing
• BP is working on a number of projects to further
  the appraisal of the Mist Mountain coal field
