RESEARCH AND DEVELOPMENT
Wellstrat Services Limited pursues an active research programme, in collaboration with a number of top British universities. This ensures that personnel keep fully up to date with, and are at the forefront of new developments within the industry. Projects include
- Early Cretaceous palynology and palynofacies analysis of the UK
- Late Cretaceous palynology and palynofacies analysis of the USA
- Application of palynofacies
- Late Cretaceous and Tertiary biostratigraphy and zonation of North Africa
- Sequence stratigraphical modelling and correlation of Palaeozoic, Mesozoic and Tertiary sequences across North Africa
- Wellstrat's personnel were involved in the development work of biosteering in sand dominated sequences and routinely offer this service at the wellsite
- Potential of the use of biostratigraphical control in the exploration of the Tertiary of Uganda
Wellstrat is always seeking to develop and update its database of knowledge and expertise. This is achieved through expansion into new geographical areas, developing and improving in-house knowledge, and pursuing an active research programme.
Wellstrat is particularly active in Sudan. This is a frontier area for palynological studies, and considerable knowledge and experience has been gained from a multi-well correlation study of the Muglad Basin in Southwest Sudan. Sequences from Neocomian to Quaternary have been studied for palynology and palynofacies. A full understanding of the stratigraphical distribution of palynomorphs from this palynofloral province has been achieved. Projects Wellstrat's personnel have developed include:
- Multi-well correlation study
- Single well analysis
- Hot-shot studies
- Development of a photographic atlas of key palynomorphs
- Integration of palynological data with wireline logs
- Palynofacies analysis and subsequent palaeoenvironmental analysis
- Training in sequence stratigraphical analysis of the Muglad Basin
Wellstrat's personnel and associates continue to be very active in Libya. We have developed unrivalled experience in the biostratigraphy of Palaeozoic to Tertiary sequences with particular emphasis on Cretaceous and Tertiary sections of the region.
- Multi-well correlation studies from Palaeozoic to Neogene
- Development of palynological, micropalaeontological and nannofossil biozonations of Cretaceous and Tertiary sequences
- Palynofacies and microfacies analyses
- Sequence stratigraphical modelling and palaeoenvironmental reconstructions
- Development of a photographic atlas of key forms taxa from palynological, micropalaeontological and nannofossil disciplines
