PetroStrat Ltd stratigraphers have a wealth of experience in the provision of integrated biostratigraphic and multi-well sequence stratigraphic services throughout the world and we specialize in provision of wellsite biostratigraphy services.
Wellsite services summary
Wellsite services-deep water
PetroStrat has routinely provided deep water wellsite services in many areas, e.g. West Africa, East Africa, Egypt, the Gulf of Mexico, eastern Canada and the South China Seas.
Provides fundamental geological data (for minimal cost compared to the overall operation) enabling calibration of seismic while drilling. Can result in significant modification of the well plan, saving rig time and enabling confident subsurface modelling.
Wellsite Services-North Sea
Tertiary Assets: PetroStrat have been one of the principal providers of biostratigraphic services to companies targeting Eocene-Paleocene hydrocarbon accumulations across the North Sea since 2001. During this time we have undertaken palynological and micropalaeontological studies on >40 fields and provided real-time wellsite support on over a hundred wells with Tertiary targets.
Cretaceous Assets: Providing high resolution biostratigraphy to Upper and Lower Cretaceous well sections is a major strength. In more argillaceous areas, integration of palynology (non-acid) and micropalaeontology provides a highly refined biostratigraphic zonation that permits recognition of by-pass surfaces within claystone dominated intervals. We have also provided real-time nannopalaeontological & micropalaeontological wellsite support on numerous horizontal Cretaceous well sections (Norway, UK, Denmark & Holland), as well as using both disciplines in tandem to help monitor the Stratigraphy of HP/HT wells requiring casing to be set above the BCU.
Jurassic Assets: Our team of Jurassic palynology & micropalaeontological wellsite experts have vast experience in the Upper, Middle and Lower Jurassic across the UK, Norwegian and Danish sectors of the North Sea. We frequently provide wellsite micro support to HP/HT wells in the Central Graben area and have been involved in numerous reservoir scale studies. Wellsite acid based palynology has been applied to the Jurassic on several non HP/HT wells. Non-acid palynology has also been successfully applied in Upper Jurassic strata.
Non-acid Wellsite palynology
PetroStrat has developed a non-acid palynology processing technique that totally avoids the use of harmful chemicals. This has opened up huge possibilities for the application of this science in real time at wellsite.
