EP Decision Making

• Modeling
• Possible effect and risk estimation
• Cost estimation
• Variants comparison
• Final decision

3
How to improve decisions?

• To improve modeling by
• deeper integration of all the relevant data
• geological knowledge management
• To manage all types of uncertainties which are
  risk sources
• To provide the uniform base for different
  projects comparison

4
What does PANGEA offer?

• The most comprehensive prospect generation and
  reservoir prediction MDI software with embedded
  geological knowledge management tools
• Uncertainty control over all the classification
  and prediction results
• The ways to support projects feasibility
  comparison with Multi-D interpretation of GG
  data in regional frame or globally

MultiD Interpretation Principle

• Using of MultiD attributes
• at any stage of geological modeling
• instead
• operation with attributes one by one

MultiD Interpretation Methods

• Unsupervised classification. Multiattribute
  anomalies
• Supervised classification
• The best MultiD attribute extraction and
  prediction of reservoir parameters
• Applied for sets of seismic sections
• and/or cubes (ReView) or for sets of maps
  (Certainty)
• and for core and log data (PetroExpert)

Knowledge management tools

• Petrophysical relationships library and general
  petrophysical model (PetroExpert)
• Solutions path storing and reapplying for model
  monitoring or similar geological settings
  (Certainty and ReView)
• Collecting informative attributes combinations
  (Certainty) and multiattributes images of
  productive zones (Certainty and ReView)

Portfolio management with Nedra

• Prognosis of oil prospective zones (blue) for
  four blocks made with Nedra software overlaying
  Murzuq basin petroleum system scheme after Don
  Hallett (Petroleum geology of Libya)

Prospecting risk assessment with Certainty

• Coloured
• Multi-D attribute highlights possibly productive
  zones (85 of known in the region fields lies
  within coloured zones)

18
Data mining in geology

• Echo allows to use the production data for
  geological model elaboration and IOR operations
  analysis
• ReView and Certainty enable to find the data
  combination corresponding to oilgas presence and
  their relationships to reservoir parameters

Data integration

• Well data are integrated into the prospect or
  reservoir model via petrophysical model of
  reservoir rocks with PetroExpert software
• Seismic, potential fields, satellite imaging data
  are considered by Certainty as components of
  Multi-D attributes. The best Multi-D attribute
  may contain non-seismic data along with seismic.
• Production data are incorporated into geological
  modeling with Echo software.

The main result

• Over 30 improvement of drilling success ratio
