Core.
Petrophysics depends on access to many types
of data, particularly log and core together.
A wide choice of tools are available for bringing
the core data into the interpretation including
plotting, editing, upscaling, classifying and
fitting function definition. All of these can be
found in the application modules Techcore(Tco), Saturation-height modelling (SHM), and
CoreDB(CDB).
Core data storage and manipulation are vital
tasks. Once they are properly managed, the
effective integration of core data with other
sources requires reconciliation for reasons
of differences in measurement scale and
measurement environments. Integration and
reconciliation are facilitated by visualisation,
quantification and upscaling.
Log.
Log data are the fundamental data resources
available to petrophysicists. Now, the term
includes a wide variety of data types and modes
of acquisition: Wireline, LWD, continuous
recording, irregularly sampled, single value at a
sample, multiple values at a sample (array data),
image data, real-time data streaming.
Day after day petrophysicists and log specialists
are loading, manipulating and analysing large
quantities of log data. Experts go further with
specialised interpretations addressing advanced
petrophysical questions.
Find these activities in the following modules:
Quanti (Q), Quanti.min (Q.m), NMR, Thin bed
analysis (TBA) and Saturation-height
modelling (SHM)

Fluids.
Reservoir layering, continuity and
compartmentalisation are key elements of
detailed reservoir characterisation. Their
effective analysis is enhanced by bringing
many different strands of data to bear on
the problem. You can do this within Techlog
where the FPress (FP) and Fluid Contact(Fc) modules evaluate multiple contacts
within compartmentalised reservoirs to derive
minimum, maximum and most likely depths for
fluid contacts in complex reservoirs.
The resultant contact surfaces and fluid typing,
by compartment, can be visualised in 3D and
instantly updated, should analyses change.
Geology.
In addition to the well-by-well view, you can
post data onto maps, see the well spatial
relationships in 2D/3D and assess correlations
and trends qualitatively and quantitatively
through the subsurface. Primary tools in the
geological workflows include log data for
correlation and geological characterisation, core
data for facies descriptions and image data for
structural and fracture analysis.
Core and log data are used very effectively
together within Ipsom (Ips) for example
to characterise facies; borehole image
interpretation in all its forms is the main activity
covered by the Wellbore imaging(Wbi) module.

Earth Model.
Show petrophysical and geological data
and results as a 3D view of the sub-surface
within the same environment where detailed
interpretation of those data are performed.
Access the 3D graphical library of 3D Vue (3DV)
to build a visualisation of an Earth Model
which you can then use to explore the interwell
space. The 3D graphics toolkit is also used
within Wellbore imaging (Wbi) to represent
image data and dip planes.
Now petrophysicists work within the context of the
full reservoir view in Techlog.
Geophysics.
The need to tie seismic survey data into well
information is paramount in successful seismic
analysis. Well data are often considered the
ground-truth for seismic data.
Preparation of the log data is best done within
the log domain using the neural network inK.mod (K.m); thus, in Techlog you can use
Geophy (Ge) a comprehensive, single-offset,
synthetic seismogram package that includes
time-depth functioning from checkshot and/or
sonic log data, fluid substitution and synthetics
filtering.
Then compare these and other petrophysical
results directly against seismic data (loaded
from SEG-Y).

Data handling.
Rapid and effective
organisation of data is
paramount. Understand
the data that are present,
understand their limitations,
plan the steps required to
repair data and then carry
out those repairs on large
amounts of data at once,either through detailed
query commands or
through graphical tools.
Within a Techlog project there can
exist one or more wells, each with one
or more datasets, each with one or
more variables. There are no software
limitations to the storage.
Make sense of what can amount to
very large quantities and variety of data
through data tools such as inventories
for each data type in the project.
Search for and repair erroneous
naming or unit assignment; ensure thecorrect family and/or alias attribution
is made. By this means, performing
multiple well data processing becomes
very efficient in the system.
Datasets hold data at a single
reference, which can be regular,
irregular, depth (MD, TVD, TVDSS, etc.)
or time-based, or just a simple index
count (e.g. sample ID for core data).
Images and complex array data curves
are stored within the same robust
data model.
Data Management
When simple editing is not sufficient,
turn on the power of the many graphical
and calculation-based tools for more
complex data processing.
Data can be re-sampled, shifted,
despiked, clipped or upscaled.
Perform mathematical operations such
as find derivatives, integrate, filter, spline
or linearly interpolate or standardise.
Frequency domain filtering is a powerful
option in this category of tool.
Multiple wells may require inter-well
normalisation, for instance before
computing formation properties. Ensure
full and close user control of this
operation with a graphical interface to
view progress and results at all times.
Data Processing
Data inventory and query
Inspection and review of the values
or content of simple curves, arrays,
zonations and well properties are
facilitated by dedicated spreadsheet-
type editors. These can often be
linked or copied directly into ExcelTM
for reporting or sharing data
with colleagues.
Combine, re-size datasets within
wells or merge data from several
wells into a composite well as the
process may require.

Viewers.
There is an enormous range of
customisable and interactive
viewers that you can use to look
at your data. All plots can be
conditioned by depth or zone
ranges to focus your views to
the matter in hand. Once a plot
is made for one well, apply it to
many other wells directly, or after
storage. Run previous templates
again by the double-click. Rapidly
build matrix plots of histograms,
cross-plots, box-plots to see
cross-relationships between
many data simultaneously. Data
selected in plots are instantly
identified in all other plots that
share a common reference.
All aspects of the plots are
customisable; freely mix regular
and irregular sampled data;
drag & drop arrays and images
onto the plot and easily add
log or core data on top; vary
the scale factors of tracks to
amplify sections, or look in
detail at core photos; create
cross-plots and histograms on
the plot that can be live with the
data in the display and updated
by dragging up and down the
plot; add colours and shadings
to custom designs or choose
the built-in templates.
Customisable
Box-plots, histograms and
cross-plots allow you to take
data out of the depth domain;
in one dimension look at CDFs
and PDFs across one or more
wells; in two dimensions
explore relationships with fit
lines, fixed or free; see the
actual data plotting or the
frequency density distribution,
that is such an aid to pickingend points in analyses; choose
subsets of data and calculate
instantly the fit lines through
the restricted data; see your
data choice highlighted in all
other viewers using the same
reference system.
Broad and interactive
In Techlog, graphical tools are
more than cosmetic add-ons to
the system. Intelligent use of plot
structure and colours make the
pictures a truly integrated part of
the solution process, facilitating
complete incorporation of all
data types within the many plot
options available.

User programming.
PythonTM is an open-
source scripting language
that has been harnessed
to work inside Techlog.
You can use the full power
of the Python language;
for example you can
customise integrated
workflows or generate
data access routines that
link directly into Oracle
databases. It is powerful,
yet can be incredibly
simple.
Within the platform, there is
an editor/parser environment for
the PythonTM
language together
with libraries of access-functions
to the data, plot objects and
the calculations under the hood
in Techlog.
There is no need to maintain
a dedicated compiler for the
language, which keeps installation
very simple and managed entirely
within the Techlog program.
Comprehensive
Tap into the brainpower of
thousands of developers and
practitioners in PythonTM, from
all over the world, to make
your special application that
accesses the Techlog data
and plot objects that much
more efficient.
Be effective with a few lines
of program that yet can be
run on multiple wells and
multiple zones without the
user having to program a
lot of housekeeping code to
make it happen.
Short learning curve
Python scripts permit the
automation of many tasks; for
example, establish a batch
process that periodically reads
a real-time data stream and
automatically processes a set
analysis workflow to produce a
preformatted output product.

Statistical analysis.
There are many statistical
analysis techniques
available for obtaining a
different insight into your
data. Looking at data
shape, data structure,
looking for data patterns,
every analyst knows
that these are extremely
important tasks. In the
Techlog platform these
are aided by the GUI
and the inter-process
interactivity.
Create tables of simple
exploratory statistics that cut
through the data in many
different ways. Easily produce
reports and synthesise large
volumes of data. For final
output archiving or compilation,
directly transfer the reports
into ExcelTM or into the plot
header/footer region of the
output product.
Calculation of statistics on
histograms and in the Data
editor further facilitate this
important means of data
characterisation.
Access multiple linear
regression for a quick look at
multivariate trends in your data.
The basics
Increasing in sophistication,
use different techniques of
Factor analysis to make choices
amongst input data when
preparing specialised neural
network models for classification
and function building.
Another more frequent task is
to perform data reduction and
correlation analysis to assess
importance amongst input data.
Make use of the new Decision
Tree analysis tool for building
classification rule sets.
Factors
Correspondence analysis allows
you to compare descriptive
data class assignments in an
objective manner.
For instance, measure the
performance of your facies
prediction results.
Correspondences

Ipsom.The intelligent classifier
Advanced classification technique Comprehensive statistical tools
Automatic facies identification
is playing a key role within the
Oil & Gas industry. Ipsom (Ips)is
a unique classification module
that brings added value to
interpretation workflows.
The 2D indexed and probabilised
self-organizing map (Ipsom) is
designed for use in:
geological interpretation of well
log data and facies prediction
optimal derivation of
petrophysical properties (, K,
hydraulic units etc.).
During the final control and
validation phase, results
are quantified and refined
through an iterative process.
High quality statistical and
graphic tools with total
interactivity and great ease
of use, lead to a better
understanding of coherence
between core description,
log responses and
consistency on the map.
Self-Organising Map at
initialisation phase
Sorting and organisation phase
of the grid of nodes
Indexation phase with facies
core description
Accurate model calibration Outputs
The key to the classification
process is calibration. The
aim of calibration is to give
each neural unit an actual
geological meaning: this is
known as the indexation
phase. Each neural unit
is assigned a code that
corresponds to a geological
interpretation (detailed core
description). This stage
is essential for a direct
interpretation of electro-
facies in sedimentological
terms.

It is a straightforward but
efficient tool that offers a simple
interpretation and a more accurate
reservoir characterisation
K.mod (K.m)is not a black box
tool: the users keep full control of
the input parameters and receive
clear feedback on the log quality and
model quality, at all times.
Uncertainties can be managed:
on inputs: back propagation
method to check the contribution
of each input
on output: self-organised map is
categorising data samples in the
training and validation data for
their effectiveness in modelling the
target data
Possibility to weight inputs to force
the model to reach extreme values.
Optionally standardise output and
learning data distributions to match
dynamic ranges.

Techdata.Data management
Data management is all about
data harmonisation for efficiency
of access. Multi-well capability is
built-in from the ground up. Powerful
tools are available in Techlog with
which to identify the data that are
present, to understand any naming
or unit problems, to correct those
issues rapidly in order to arrive at astate where access to 1000 wells
data is as straightforward as access
to two wells data.
Techlog easily handles regular or
irregular depth or time reference
systems simultaneously.
The simple principles of a
Data Family or a Data Alias
allow you to rapidly harmonise
names, units, scales, colours
etc. across your entire project,
and allow you automatically
to control preferential data
selection
Clarity
From potentially many
hundreds of wells in a project,
use powerful data mining
tools to rapidly understand the
data that are present and any
errors of naming, units and
families assignment, etc.
Using the combination of data
inventories and detailed data
queries, search, find and repair
spurious names, units and
family/alias assignment.
Arrive at fully harmonised
datasets ready for efficient
multi-well work in a fraction of
the time.

Techdata.Data processing
The final key step in the data
preparation workflow is the
processing of curves to enhance
their accuracy and usability.
Techlog provides a broad range
of graphically based tools to make
the most of your data and ensure
full user control at all times.
It is very important in data
manipulation to be able to visualise
the process quickly. The platform
includes the means of graphically
editing, trimming, clipping, depth
shifting, deleting, joining, merging
(splicing), despiking, smoothing,
interpolating and standardising your
data right off the plot.
Graphical methods allow the analyst
to keep control of the process.

Magnified views of header and footer
A key function for the
user is to produce copy to
illustrate reports or share
data and interpretations
with colleagues
In an operational
environment, re-usable
templates that combine
headers, footers, tables,
cross-plots, histograms
and layout tracks within a
single display often describe
a product that defines
the operation
Build well composites
piece-by-piece, save the
template design and apply
directly to the next well in
the operational sequence
Annotate the details of
the plots for ease of
reference long after the
operation is completed
Other methods of output
of plot copy include screen
shots, .CGM, .WMF or .PDF
files, and hard copy to
page, continuous sheet or
large format plotters located
anywhere on your network

PythonTM
Go further with user programming
Introduction
PythonTM
is an open-source
scripting language that Techsia
has incorporated within the
Techlog platform. In the world
at large, it is in use today across
many industries; it is being
developed by many individuals
to perform all manner of
programming activities from
simple calculations to complex
interface and databaseimplementations. When you
use Python in Techlog, you have
available an enormous resource
of technology that is derived
from a user-base numbered in
the many thousands.
What Techlog provides
Techlog
PythonTM
editor
combined with libraries
that permit access to:
All Techlog data objects
(e.g. wells, datasets,
curves, properties etc.)
Maths/Statistics routines
Petrophysical calculations
(e.g. shale, porosity and
saturation equations)
Plot objects (e.g. access
a pre-defined template
or create a new template
within a Python script)
PythonTM script editor: example of datamanipulation with interactive help
More resources How to use it
Additional tools and library
functions through Internet
access from the PythonTM
community
Scripts can be used to access
previously compiled code
written in C++ or Fortran,
for example
Techsia has provided a large
number of ready-made
scripts that accomplish many
tasks; these can be used
as completed, functioning
scripts or as starting points
for adaptation to a specific
task of interest
Scripts can be run stand-
alone directly from the
Python editor; any script
can access other scripts as
sub-routines
Scripts can be incorporated
into Quanti (Q)workflows and
thus be applicable over many
wells and/or data interval
ranges without the analyst
having to write a lot of data
access/housekeeping code

script within a Quanti (Q)workflow table and outputdisplay in the layout

Techstat.Comprehensive exploratory data analysis
Classification and normalisation Regressions
Hierarchical clustering:
find similarities between wells
group wells together
if necessary, align data
responses using sophisticated
Gaussian analysis, group-by-
group amongst wells
results are displayed in
a dendrogram
Decision Tree:
powerful classifiers where inputs
are mixed and incomplete variables
(qualitative and quantitative)
rank inputs by their information gain
deduced rules can help to
understand the input data
Linear (RMA, Major Axis, x/y, y/x),
non-linear, polynomial algorithms
are available
Regression and other fit lines and
functions may be created and
conditioned on filters, zonation,
well-by-well or multi-well
Fit lines may be calculated for
user-defined subsets of data
using the data selection tools and
interactivity between viewers
Regressions can be freely
calculated or forced through a
fixed point on a plot
Input user defined-equations
graphically and by keyboard entry
Hierarchical cluster analysis (HCA) dendrogram
Decision Tree rules
Regressions by selectionsand table of resulting
equations for reporting
Factor analysis Coming soon
Principal Component
Analysis (PCA) is a
useful tool to summarise
data, since it separates
the dominating features
in the dataset
Linear Discriminant
Analysis (LDA) is used
to determine the best
projection space to
discriminate between
two or more naturally
occurring groups. It
clarifies subsequent
cluster analyses on
users data
Multiple Correspondence
Analysis compares
qualitative variables
that may either be of
similar type (observed
vspredicted curves)
or be of dissimilar type
(geology vspetrophysics)
Extend the reporting of
exploratory statistics with
a new and comprehensive
reporting module. Partition
your wells by zones or
facies or fluid types, for
example, and select from
many summary statistics
Build P10, P50, P90 output
reports for sharing with
colleagues
Analyse uncertainties in
zone summary information
with Monte Carlo analysis of
results tables
