The most widespread source for subsurface data is 2-D and, increasingly, 3-D seismic. Data related to boreholes - such as well logs and rock samples - provide crucial complementary and calibration parameters.

In the past, and even today, the prevailing approach in the interpretation of these subsurface data is static. This means that great efforts are made to describe subsurface structures and property distributions in their present state.

However, understanding and modeling past geological processes that were responsible for the present status of the subsurface has so far not been sufficiently emphasized.
In petroleum exploration and production it is an essential requirement to understand these past geological processes - especially petroleum generation and migration - which determine whether or not a trap contains hydrocarbons. Hence, it is crucial to understand the dynamics of relevant processes responsible for the present day geological conditions.

As modeling of geological processes relies entirely on a subsurface database and related, intelligently structured data archives (often called data models), it is essential that the numerical simulation is linked as closely as possible to these data sources.
This is easily achieved by direct binary access to seismic data and interpretation tools like OpenWorks, GeoFrame, SeisWorks, IESX, etc. It is common practice to organize and store subsurface data in more or less sophisticated data archives that can be screened and manipulated electronically.

An electronic data archive enables information to be exchanged, reviewed, and thereby enriched and updated. Even the most refined interpretation utilizing advanced interpretation software and databases, however, produces static information for stratal terminations, seismic facies, lithofacies and property distributions, etc.
Such static data archives can be brought to life - and at the same time generate a great deal of added value - by dynamically modeling the geological processes behind it.

 



     



Sedimentological modeling and reservoir characterization:

  • 3D environmental interpretation of depositional sequences

      

      



  • Sedimentological interpretation of well logs (patterns and diagenesis)

      



  • 3D Stochastic modeling
  • Flow unit determination

      



  • Facies modeling

Petroleum reservoir engineers use a variety of computer-generated statistical modelling techniques to generate the large number of facies models (realisations) required to assess the uncertainty in their understanding of reservoir heterogeneity.

However, the resulting models are often not geologically realistic. More recently, methods such as marked point processes and models based on training images have been developed in order to incorporate geological patterns into facies models.

These methods are not always good at reproducing the complex shapes of channel fill bodies and the correct spatial relationships between the various sedimentological entities.

Furthermore, they tend to be computationally intensive as they are grid-based.

Faults control:

  1.  Whether there is or is not hydrocarbon in a trap.
  2.  How much hydrocarbons.
  3.  How these hydrocarbons are distributed:
    • Vertically among a series of stacked sands.
    • Distributed within single sand among a series of fault compartments.

Here are many reasons why you should be doing routine fault seal analysis:

  1. Dry Holes (Leaking faults can bleed a trap dry). Dry Holes (Faults can create empty reservoirs & empty compartments within the producing field). Dry Holes (Sealing faults can keep a trap from being charged). Dry Holes (Faults can channel migrating hydrocarbons away from your prospect)
  2. Limited Reserves (Fault dependent spill points can limit hydrocarbon columns to less than expected.  In addition, column heights are limited by gouge composition, fault displacement, and structural style). Limited Reserves (Faults can restrict hydrocarbons to only a few of the many potential reservoir intervals)
  3. Compartmentalization (Faults control the degree of communication between fault compartments)
  4. New Plays (Purely fault dependent traps with no structurally independent closure are common AND they're more common in some areas than others)
  5. New Prospects (Hydrocarbons may be trapped along faults down-dip of dry holes). New Prospects (Hydrocarbons may be trapped along faults down-dip of known accumulations & they may be larger columns)
  6. Field Unitization (Are you giving away reserves in a highly fault-compartmentalized field)
  7. Residual Reserves (A fault that is partially sealing may trap residual reserves that remain after hydrocarbons are produced from the leaking segments).
