Exploration Workshop

Audience

Multidisciplinary teams (4-5 persons with a maximum of 20 per workshop) of petroleum geologists, geophysicists and engineers (from 0-10 years’ experience) who are involved in integrated regional projects, basin evaluations and prospect identification.

Content

Week 1: Regional investigation 
• Introduction to the workshop 
• Data gathering and organisation phase • Introduction and tectonic/stratigraphic development 
• Biostratigraphic framework: 
Objectives: 
- To generate a stratigraphic framework for your field 
- To identify all potential reservoir, source rock and seal developments 
- To identify and quantify all potential hiatuses 
Itinerary:
Taught component:
- Introduction to (bio)stratigraphy as the vital, initial step in basin studies
- Outline of what to look for in the stratigraphic contribution
- How to generate a general stratigraphic framework for the study
- The gross stratigraphy of the study area
- Structural geology and seismic interpretation
Attendee’s component:
- Generate stratigraphic columns for outcrop and subsurface
- Identify all levels of potential reservoir and seal development
- Identify all levels of potential source rock development
- Individual group presentations on the stratigraphy of the study area
- Begin seismic interpretation
Deliverables:
- Understanding of the stratigraphy of the study area, with regards timing, duration and depositional setting of each stratigraphic unit
- Stratigraphic relationship between each depositional/stratigraphic package
- Regional stratigraphy
- Tectonic-stratigraphic evolution and basin outline
- Major structural elements of the study area

Week 2: Sedimentology, structural geology and seismic interpretation
• Structural geology
• Reservoir / seal facies identification and mapping
• Reservoir distribution
• Continue geophysical assessment (seismic and non-seismic)
- Define prospects using seismic data, identify main horizons, tying well data to seismic
- Picking seismic horizons
- Loop tying
- Identifying DHIs
- Complete picking horizons
• Seismic Evaluation
- Identify and correlate faults
- Identify leads
- Time contour mapping
- Time/depth conversion and contouring
- Identify spill points
- Volumetric calculation
• Team Presentations
- Reservoir correlation
- Reservoir description and properties
- Static reservoir model
- Seismic interpretation
- Identification of leads

Week 3: Continue sedimentological investigation and Geochemistry
• Stratigraphy and basin profile continuation of week 1, day 5 tasks.
• Reservoir/Seal facies identification and mapping and Reservoir distribution and properties.
The sedimentological component will build upon the basin knowledge gained from the data organisation, structural, geophysical and stratigraphy components. This aims to achieve an understanding of the potential reservoir and seal distribution and characteristics within the study area, over a two-day period. The following aspects will be covered through a mixture of taught and practical sessions:
- Introduction to sedimentology and its role in basin studies
- Types of sedimentological data, their uses and integration
- Depositional and diagenetic models (clastic and carbonate)
- Identifying, predicting and mapping reservoir and seal distribution
- Reservoir properties

Week 3: Continue sedimentological investigation and Geochemistry (part 2)
During this phase the following will be identified/generated:
- Depositional and diagenetic models
- Main reservoir and seal facies from those identified in depositional and diagenetic models
- Likely distribution and geometry of main reservoir and seal facies
- Calculate and map (contours) thicknesses for each reservoir or seal facies
- Integrate structural data for relevant time slices
- Combined reservoir-seal couplet maps
- Mapping of net pay from composite logs
- Overlying of net pay for each reservoir or seal facies identified
- Integration of diagenetic model data onto maps
- Final product: maps for each identified reservoir and seal showing facies thickness, net pay distribution and seal distribution to predict where effective reservoir-seal couplets exist.

Week 4: Play Fairway Mapping, Risking and Ranking
• Play fairway mapping
• Prospect identification
• Risking
• Ranking
• Preparation and delivery of prospect memorandum, final presentations and results. During this final week all pertinent interpretations generated during the previous weeks will be integrated into a series of key play fairway maps. Petroleum system events charts will also be created. Resultant maps will be used to evaluate, risk and rank prospects within the study area.
• Volumetric calculations
• Final team presentations

Learning Objectives:

The trainees will be put into teams and given a dataset comprising 2D seismic lines, composite logs, geochemical data, core analysis data, research papers, reports and various maps. They will work up the data under the guidance of the instructors. Teaching will comprise short taught lectures and guidance and discussion regarding the data. Understanding and knowledge gained will be tested during preparation of the end of week presentations and during the workshop through discussions and questions.
