Sub-Thrust Exploration

Valuing Decommissioning Deferral.

Onshore Bolivia. Constructing multiple balanced structural cross-sections based on surface data, seismic, and well data. Estimating prospective resources.



The structural complexity in an onshore thrust tectonics setting is often associated with poor data and requires a comprehensive multi-disciplinary approach. The client had a small in-house technical team and desired an integrated study to explore deeper prospectivity.


ERCE carried out a detailed analysis of all wells in the block to understand lithologies, repeated stratigraphy, fracture parameters, and pore-pressure changes. An extensive literature review and geological surface evaluation was undertaken to understand the detailed tectono-stratigraphy and to build the framework for a structural model in MOVE software. We interpreted several regional 2D seismic lines and a 3D seismic survey.

We also worked closely with the client’s team and a national oil company to incorporate their in-depth knowledge and experience in the region.

All these data were pulled together and integrated to construct multiple balanced structural cross-sections that not only explained the well results at shallow depth but also developed models for sub-thrust prospects.

Part of this study was presented at the conference ‘The Geology of Fractured Reservoirs’ at the Geological Society of London in 2018.


Why working with ERCE is beneficial to client:
The key to undertake such projects is a close cooperation between highly skilled team members. ERCE has expertise in structural geology, seismic interpretation, petrophysics, and reservoir engineering. If required, we pull in professional associates to make sure all technical aspects are thoroughly covered. ERCE used a range of software like Kingdom Suite, IP and MOVE for this study.
