This 5-day course is about:
o Understanding plays and Play-based Exploration: Why Play-based Exploration is best practice
exploration? How is it used in the Exploration process?
o How to identify new plays using global concepts, understanding of basin types, petroleum system
principles, basic geological principles and “geo-logic”
? What makes a basin good for exploration?
? We know a lot…even when “we have no information”
o How plays are evaluated by mapping geological nature over their extent
? how the evaluation of conventional and unconventional plays differs
? Mapping play fairways
o How plays are “risked”: what is Play Chance vs. local risk. Common Risk Segment mapping
o Calculating Yet-to-find resources for conventional and unconventional plays
o How plays are used to decide where to explore next
o How the play’s evaluation and assessment is the fundamental for evaluating the assessing the
prospects in a play
o How to make a direct transition from the Play Assessment down to the prospect level thus
assuring prospect assessments that are geologically-based, objective, consistent and documented
and linked directly back to all the work done on the play.
This course is heavy on domain knowledge. This knowledge is mixed with lots of hands-on exercises that use the Petrel, PetroMod, and the Petrel Exploration Geology tools to do probabilistic Yet-to-find volumetrics and risking in GeoX.
The “traditional” method for doing Play Resource Assessment and creating the Common Risk Segment
maps that are the foundation of this process was the laborious and lengthy “light table method.” Results
of the petroleum system model were often not included.
In the digital world, the participants will learn to use Petrel (where the play fairway maps were created),
petroleum system modeling results (automatically imported from PetroMod into Petrel) to digitally
create Common Risk Segment maps that will be used with GeoX to do the probabilistic Yet-to-find
Fundamentals – Everything you need to know about Play-based exploration and Play
o Play-based Exploration and Play Resource Assessment: Why is Play-based Exploration
best practice? Why do we do it?
o The language of Play-based Exploration: Defining the basic terminology – Basin, Play,
petroleum system, lead & prospect, Assessment Unit (AU), Play resource assessment,
Play Chance vs. AU chance
o Identification of plays: How are plays initially identified? What to do when there is “no
o Chance Mapping: Making Common Risk segment maps for plays. Defining Assessment
? TRCS chance mapping exercise – Basics for making common risk segment chance maps
with Petrel Chance Mapping tool to define assessment unit polygons for play resource
Learn the basic concepts and the reasons industry does play-based exploration (PBE).
Basic terminology of PBE. Play-based Exploration and connects the PBE analysis down to
the prospect level. Learn to make Common Risk Segments maps in Petrel more efficiently
than the old “light table” process. Learn to delineate the Assessment Units (AU) and how to
extract risk factors for each one for use in Play Resource Assessment
Play Fairway Mapping – Making play-scale geological maps in Petrel that delineate the main
characteristics of the play
o Using Global concepts, regional knowledge, and geological principles in making play
o Reservoir: Making regional rock quality maps based on little data.
o Seal: Seal capacity mapping from facies and depth maps.
o Trap (Structure): Identifying the structural style for the play. Mapping areas with high
probability of structural and/or stratigraphic closure
o Charge: Identifying the effective source rocks. Using output from petroleum system
modeling: defining the Kitchen Area, migration pathways, generation and migration
timing, migration pathways
o Facies mapping of reservoir, seal, source
o Timing: Creating Petroleum System Events Charts to demonstrate timing of petroleum
systems feeding the play
o Wells: How to use wells in making play fairway maps. The pitfalls of well statistics

capacity maps in Petrel. Import oil generation maps for charge from PetroMod 3D
mode. Define migration pathways from PetroMod 3D model and import into Petrel
