Rejuvenating Exploration in the under-explored Southern Termit Basin, Block H, Chad
Delonex Energy, PESGB Conference Presentation, 2019
An accelerated exploration programme was launched in 2017 in the southern Termit Basin in Chad, following a lull in activity in the region of almost 30 years. Intensive effort from a multi-disciplinary team saw acquisition of >2,700 sqkm of 3D seismic, >500 km 2D seismic and 6 back-to-back wells.
The exploration efforts successfully characterised the petroleum system of this under-explored basin, enabled ranking and refined risking of the portfolio, and opened opportunities for fully realising its potential.
Development and Publication of Internal Guidelines : Regional Play Evaluation & Risk Mapping
OMV AG Internal Publication, 2013-2014
In order to drive consistency in risking across the global exploration portfolio, internal guidelines concerning regional play evaluation and risk mapping were developed and published company-wide.
These guidelines defined best practice workflows that could be adapted to different tectonic and depositional regimes, but encouraged more consistent treatment of risking across the assets.
Development of a Sequence Stratigraphic Framework in the Great South Basin
Paper presented at NZ Petroleum Conference, 2013
One of the initial objectives for the regional GSB study was to establish a new stratigraphic framework based on sequence stratigraphy rather than using the existing lithostratigraphic schemes.
Using sequence stratigraphy enables a more detailed subdivision of the stratigraphic section and helps to track changes in relative sea level and the resulting effects that has on sediment distribution. Once a sequence strat model has been established, it provides a tool for looking for specific features in certain parts of the basin.
Diagenesis Affecting Reservoir Properties of a Single Turbidite Bed
Paper presented at AAPG Annual Meeting, Calgary, 2005
Fine-grained, thinly-bedded, deep-water sediments are important hydrocarbon reservoirs globally. However, reservoir evaluation can be problematic because conventional logs and seismic datasets can’t resolve the detailed architectural elements and rock properties needed for accurate characterisation and modelling.
This study analysed reservoir quality and diagenetic history of core samples from a single turbidite bed along an 18m transect, although the bed can be traced laterally for over 400 m in outcrop.
