Basin Studies Symposium

10-11-12 May 2023, Paramaribo
Venue: Royal Ballroom Torarica


Six basin studies were conducted in 2022 by Staatsolie’ s basin studies team together with subject matter experts to improve the understanding of the petroleum system elements of the Suriname-Guyana Basin. The gained knowledge is being used to de-risk and promote open acreages and to share with IOCs to increase the success rate in the contract acreage. These basin studies are:
1. Gravity and Magnetics
2. Sequence stratigraphy
3. Structural restoration
4. Gross depositional environment mapping
5. Geochemical analysis (Oil, Gas, and Source Rocks)
6. Petroleum systems modelling

The basin studies symposium aims to share all the gained knowledge by the subject matter experts in-person to partcipants representing the local and international geoscience community.

Jennie Bull B.Sc. (Hons.), M.Sc.
Senior Nannopalaeontologist / Data Steward

Jennie Bull joined PetroStrat in 2014 with a B.Sc. (Hons.) in Geology and Physical Geography from the University of Edinburgh, UK, and a M.Sc. in Applied and Petroleum Micropalaeontology (with Distinction) from the University of Birmingham, UK. Over the past 9 years Jennie has been involved in biostratigraphic studies across the globe including post well analysis, comprehensive regional review studies, and real time nannofossil analysis at wellsite.
In addition to a broad global understanding Jennie specialises in nannofossils from the Equatorial Atlantic with significant experience throughout the Caribbean and Latin Americas, comprising nannofossil analysis on 9 wells offshore Suriname and Guyana, 5 of which were at wellsite, and, including stratigraphic review projects, has provided insight on over 50 wells in the region.
Jennie now plays a large role in data stewardship at PetroStrat, helping to ensure wells included in regional studies, like that provided for Staatsolie, are discussed with consistent timeframe, taxonomy and stratigraphic model despite the vintage or year drilled.

Andres Cedeno holds a Master and PhD in Petroleum Geosciences from the University of Stavanger, Norway. He specializes in Petroleum Geochemistry. Andres is interested in the application of oil, gas, and source rock geochemistry to petroleum system analyses. He has been performing consultancy work for Staatsolie as an independent consultant and also associated with This !s Petroleum Systems for Suriname. 

Simon Cole B.Sc. (Hons.), M.Sc.
Principal Stratigrapher / Nannopalaeontology Manager

Simon has 18 years’ experience in petroleum industry consulting. He completed a M.Sc. in Micropalaeontology (University College London, 2004), choosing to specialise in nannopalaeontology. From there, Simon moved to North Wales to join Robertson (CGG) before moving to PetroStrat in 2006 (a stone’s throw away, across the river in Conwy). Since 2017, PetroStrat has been part of Biostrat JV, a joint venture with HQ in in Trinidad. Simon, Principal Nannopalaeontologist, now manages the Nannopalaeontology department from North Wales, with the team diversly located around Europe and the US.
Simon has significant wellsite experience, having conducted wellsite biostratigraphy on nearly 70 wells worldwide. These include ‘biosteering’ in the North Sea, picking casing points in West Africa, to biostratigraphic monitoring on various exploration wells throughout the Suriname-Guyana Basin and Caribbean Sea.
Simon has also analysed over 250 Cenozoic to Mesozoic well sections in the office, from diverse regions including Europe, Africa, North and South America, Southeast Asia and Australasia. In addition, Simon enjoys working on basin review studies and has completed reviews across Suriname, GoM and along the West African conjugate margin.

Andrew Pepper 'Andy' founded This is Petroleum Systems LLC 't!Ps' in September 2015. In the field of Petroleum Systems Analysis, t!Ps aims to:

  • Enable People - educate generalists, experts and leaders
  • Define Direction - identify technical gaps or weaknesses and develop new tools
  • Deliver Results - perform Studies, both business and research

Andy is an innovator with over 35 years’ industry experience in Petroleum E&P, across Business delivery and in Research.

As an individual contributor:

  • After obtaining a 1st Class Honors degree in Geological Sciences at the University of Leeds, UK, he began his career with BP in 1981 as a Geologist in international exploration
  • Given the opportunity to work in BP’s Geochemistry Research Lab in the late 80s, he went on to devise models of petroleum formation that are now industry standards
  • Subsequently returning to the business as a geologist as - what we would now call - a Petroleum Systems Analyst, Andy broadened his world-wide experience and reach, culminating in a role in BP’s highly successful Gulf of Mexico sub-salt exploration program

As a leader:

  • By 2000, Andy had defined Petroleum Systems Analysis as a new workflow and introduced the Petroleum Systems Analyst as a new team role at BP; subsequently advocating these ideas more widely in the Industry
  • He continued at Hess and BHP Billiton as a functional leader in Geology and Geoscience; alternating with business roles leading US and International Exploration and New Ventures teams, both Conventional and Unconventional
  • Throughout his leadership tenure, Andy has continued as a strong advocate for technical rigor in petroleum geoscience, and specifically Petroleum Systems Analysis, together with its practical application to Volume, Risk and Value assessment

Carl Stark is the Australian Country Manager at ERCE and has over 25 years of sedimentological and sequence stratigraphic experience working with E&P companies on exploration, development and producing assets.​ He has collaborated on projects with Shell, Santos, OMV, ConocoPhillips, Murphy, BHP, Soco, Cairn Energy, Inpex, Woodside and ENI, in sedimentary basins located in West Africa, India, SE Asia, Papua New Guinea, Australia and New Zealand. ​His expertise lies in a multidisciplinary approach, tying in core-based studies with high-resolution image data and sequence stratigraphic analysis. He has worked both siliciclastic and carbonate systems, with environments of deposition (EOD) ranging from fluvial, estuarine systems, fluvial- and wave-dominated deltaic systems, shallow water pinnacle reef and deep-marine ramp carbonate systems, along with slope- to basin-floor fan turbidites systems. Also, he has guided numerous fieldtrips, with a particular focus on differentiating fluvial-, wave- and tide-dominated shallow marine systems.
