Context

Client: None
Location: Monagas thrusts, venezuela
Main goal: Charge ans seal assessment
Geology: Inverted basin
Tectonic: Subsidence, contraction, folding, thrusting

Methodology

Data analysis and interpretation
2D model reconstruction and quality control
2D model restoration over time (Dynel2D or CASSINI)
Forward 2D petroleum system analysis (Petrel/Petromod)

Other applications using similar methodology

The restoration of this workflow can also be applied to:

Geology interpretation verification
Forward stratigraphic modeling
Natural fracture modeling (fold related fractures)

Main outcomes

Interpreted cross section

NW-SE Cross section across the Monagas fold and thrust belt showing the complex fold and thrust system as well as duplexes.

2D restoration over time
