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 connectivity.

There is a full range of data loaders

and there is a developing family of data

connectors, so that you can easily source

your data from corporate data stores,

other applications or external suppliers:

DLIS, LIS, LAS 2, LAS 3, WITSML, CSV, ASCII,

OpenSpirit, RecallTM, CGM, SVG, EMF, JPG,

GIF, TIFF, BMP, PNG, SEG-Y, etc.

We have accommodated every type ofdata that you could want to use during

an analysis.

TechlogDataAPI is available to enable

clients programmers to build connectors

for other programs to directly access

Techlog data objects.

2008

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.

Data Editing

Data editor

2008

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

Nmr.Pore network and fluid distribution

T2 Conversion: data regularisation Toolbox

Adjust the T 2 data into a

single data range and a

single number of bins across

that range, irrespective of

tool source. The application

is designed to accept all

industry T2 distribution data

and to convert them into a

regularised T2 distribution

Compute porosities,

permeabilities, water and

hydrocarbon volumes through

an intuitive user interface;

the results can be displayed

immediately and controlling

parameters/functions adjusted

graphically if necessary

Using the clay-bound water

(CBW) cut-off (from constant or

curve), the NMRclay-corrected

porosity and the CBW volume are

computed. The Free-Fluid-Index

(FFI) cut-off is used to compute

the hydrocarbon volume. The

total porosity is an integration of

the regularised T2 distribution

Two estimates of permeabili ty,

the Coates and SDR permeability,

are automatically computed

from standard equations whose

parameters can be again curves

or constants and can be adjusted

graphically if necessary

Capillary Pressure from T2 distribution

Compute a capillary

pressure curve from the

The computed capillary

pressure depends on the

can be applied to the T2

distribution

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

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.

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

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

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
