One-Day Workshop on Thin Bed Pay (TBP)


Day 1 - Thursday 18th October, 2018

1. Workshop - 8am-4pm - $100.00 USD or $700.00 TTD (per participant) 

2. Technical Session - 5:30pm,Venue (TBA) - Free to members



An integrated workshop focused on the geological and petrophysical characterization of unconventional oil and gas reservoirs including, but not limited to mudstone -prone and thin bedded clastic reservoirs. Unconventional reservoirs are of growing importance both onshore and offshore Trinidad and can occur in different depositional environments with the potential for commercial development. Challenges lie is in their detection and accurate evaluation.

Scope: Comprehensive non-proprietary Oral presentations on petrophysical workflows, core, log and geological models related to log characteristics and reservoir productivity of TBP. 

TBP Opportunity, TBP Characterization, TBP Volumes, TBP Productivity and Drilling & Completions Methodology.

Data sharing to include

  • Logs and Static Data
  • Cores
  • Dynamic Data
  • Drilling and completion Methodology


Program topics would include one of more of the following:

1. Introduction to Thin Bed Pay

  • Thins beds from Geophysical, Petrophysical, Geological/Sedimentological viewpoint
  • Vertical resolution of conventional logging tools
  • What is low contrast pay reservoir?
  • Clarification on Clays vs. Shales

2. The geology of thin bed hydrocarbon reservoirs

3. Data Acquisition in TBP:

  • Use of mudlogs/drilling data
  • Better use of conventional logs data
  • Hi-res FE tools/advanced logging technology (NMR, spectroscopy tool, triaxial res tool, borehole imaging, formation microscanner tools) and techniques (eg. Thermal decay time in casing) – recommended logging speeds
  • Seismic inversion techniques
  • Core data (Core handling, preservation, etc) – Best practices for unconsolidated sands and thin beds
  • Dynamic data – pressure/flow tests 

4. Conventional and advanced petrophysical analysis including various descriptions for  porosity, permeability, net-to-gross and water saturation

5. Issues and Gaps – case histories

6. Business Impact – issues related to booking reserves for TBP as SEC does not embrace inversion/probabilistic methods – how can PLT data help in proving TBP

7. Core demonstrations
