Basin Evolution
Basin Evolution
The South Atlantic Ocean initiation led to a small tectonic subsidence phase
followed by a thermal subsidence.
Following these two phases, a lithosphere bending occurred and led to the general
basin form.
12
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
All these phenomenon produced a continuous increase of the relative sea level
through time.
Basin Lithologies
An early Barremian basalt flow fills the
basin base.
These basalt levels are followed by tuff,
conglomerate and continental sandstones.
A first apparition of shallow oceanic facies
occurs during Albian and Cenomanian.
During Santonian and Campanian,
continental deposit occurs and leads to an
upward increase of shale proportion.
Finally oceanic facies reappears during
Paleocene.
● Lower-Upper Cretaceous,
● Cretaceous-Paleocene,
● Paleocene-Eocene.
13
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
Three main major erosions phases occurred:
Basin Lithologies
Lateral variations of facies can induce potential stratigraphic traps.
14
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
Good sand proportion deposits are identified at the slope base. It is the equivalent
of the proven African turbiditic target.
Petroleum System
Burial mechanism: regular and gentle deepening of the basin through time.
Oil windows is reached between 40 and 30Ma ago.
15

Gas window is reached between 15 and 5Ma ago.
Assessment
16
TemisFlow 2017 - 2D Basic Training

Importing Data
Importing Data
When starting with a new project, it is mandatory to first create a Study before
importing the input data.
The study contains all the objects (wells, templates, horizons…) related to a given
model.
The input data that will be imported are the following:
24
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
● A 2D template interpreted on a seismic section,
● One calibration well with Temperature and Vitrinite Reflectance logs.
Importing a 2D Template
From the Study Explorer, right click anywhere
and select Import.
In the newly opened wizard, expand 2D Section

Building the Stratigraphy
Building the Stratigraphy
In TemisFlow, a model, or GeoGrid, is built within a Scenario.
A Scenario is an entity gathering all necessary data to build and analyze a model. It is
the central element of TemisFlow. It has the same look and feel and philosophy
whatever the model dimension.
32
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
Once the 2D model and its associated scenario are created, the first model building
step will be the definition of the Present Day geometry. In order to draw this
stratigraphy, the 2D template will be used.
Creating a 2D Scenario
The 342km long section will be created at the same
time of its associated scenario. To do so:
In the Study Explorer, right-click and select New
> Scenarios > 2D Scenario.
In the wizard, name the scenario Pelotas_Model
and click on Next.
In the next panel, define the
section coordinates with:
● X0=0, Y0=0,
● X1=342000, Y1=0.
An empty 2D GeoGrid named
Pelotas_Model is opened.
Save it using Ctrl+S. Click No.

● Present Day Geological Description where geometries, lithologies and the petroleum
system are defined using maps or values,
● Geological Event for geometry and lithology evolution through time,
● CrossSection : drawing mode where geometries and lithologies can be defined at
present day and through time. It is synchronized with the other panels.

Defining the Lithologies and an erosion
Defining the Lithologies
Now that the model geometry is defined, it has to be filled with properties. To do so, a
Lithology Library needs to be added to the scenario to define the lithologies used in the
model.
The Lithology Library is where rock properties and lithofacies indexation are defined. It
can be imported or created from scratch and edited at any time.
44
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
When lithologies are defined, the next step is to fill the 2D section using painting tools.
Importing Lithology Library
In the Scenario Explorer, right-click on
Lithologies Library and select Import.
Use the Browse button to reach the dataset.
Tick Pelotas.xml.
Click on Finish.
A warning message appears indicating that the
library is properly imported. Just click on OK to
validate the import.
45
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
The library is automatically added inside the
Scenario Explorer and can be used to assign
lithologies to the section.
Presenting the Lithology Library
The Lithology Library is organized around several elements:
46
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
● A Lithofacies list where facies categories and lihtofacies are
created and listed.
● An Indexes Table Edition mode where lithofacies indexes
are defined.
● An Edition Mode to customize facies parameters such as
facies porosity, permeability, capillary pressure….
Defining Lithology Indexes
From the lithology list, select the Carbonates, Clastic, and Salt categories.
Drag and Drop them in the Indexes for Sedimentary Facies table.
Drag and Drop the Igneous Rocks in the Indexes for the Lithospheric Facies table.
Click on the icon Fill Empty Indexes Automatically for the Sedimentary and

Defining the Kerogens
Defining the Kerogens
Now that the 2D section contains facies property, it has to be filled with source rock
properties. To do so, a Geochemical Library needs to be added to the scenario to
define the kerogens used in the model.
The Geochemical Library contains fluid and geochemical properties and can be
imported or created from scratch.
58
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
When kerogens are defined, the next step is to fill the 2D section. This filling can be
constrained by the lithology.
Importing the Geochemical Library
In the Scenario Explorer, right-click on
Geochemical Library and select Import.
In the wizard select IFPEN Default Library and
click on Finish. The library is added below

Filling the 2D Section with Kerogens
To assign the kerogens, the following assessments will be used:
● If the facies is Organic_Shale, it corresponds to the Upanema Source Rock,
● If the facies is Organic_Shale_Marl, it corresponds to the Ptbeds Source Rock.
To define it, two methods will be used, first using a conditional formula and second using
the filtering capability.
Open the sedimentary model of the Geogrid.
Click on the Source Rock mode edition
in the top right tools bar.
Reach the Property Editor panel and click on P1 in the Set Cells Values section.
Click on
to Select a Property and select Facies in the wizard to set P1 = Facies.
62
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
Do the same for P2 = HC_Source.
Defining the Upanema Source Rock
Enter the following formula in the Elsewhere field: if(P1==X,Y,P2).
X is the Organic_Shale facies index and Y the Upenama Source Rock index.
Click on Apply.
63
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
It means that if Organic shales are present, Upanema source rock properties is set.
Defining the Ptbeds Source Rock
Open the Filters panel and extend the Filtering By

Select the Pelotas library and tick Facies. Untick then all
facies except Organic_Shale_marl.
Go back to the Property Editor panel and define the

Defining the Lithospheric model
Defining the Lithospheric model
The Lithospheric model can now be defined. In TemisFlow, the basement follows the
McKenzie model: it is split into three main units (Upper Crust, Lower Crust and Upper
Mantle), it is isopach (the overall thickness cannot vary through time) and rifting
events are defined thanks to beta factor profiles.
73
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
As for the sedimentary part, lithologies and geometry through time have to be
defined.
Defining the Lithospheric model Lithologies
Double click on Lithospheric model in the Scenario Explorer.

Defining a Rifting Event
In the CrossSection Panel right click on the age 130Ma.
Select Use as Crust Geometry Description.
However in the present model, the hypothesis is an isopach lithosphere at 130Ma and
a rifting between 130 and 90Ma . The age of description has to be changed to get a
forward rifting.
75
TemisFlow 2017 - 2D Basic Training
@Beicip-Franlab
Before this step the age of reference of riftings was 0Ma, it means that all the defined
rifting would have been backward.
Defining a Rifting Event

Launching a Pressure-Temperature Simulation
Now that the model is fully defined (all interesting sections and libraries are validated
with a green check), a first simulation can be launched.
This simulation will be a Pressure-Temperature simulation: it will allow us to estimate
the pressure and thermal regimes over the section and check its calibration at well
location.
