Techlog Interactive Suite 2008

Your essential platform. The platform includes all the fundamental activities to which everyone who uses petrophysical data needs access. The modules included (next page) within the platform are bundled together and offered as a complete package. ©

Every time Techlog is run on a computer, a platform seat is used irrespective of the application module or modules that will eventually be applied in that session.

Data management Tp 3DV

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 a state where access to 1000 wells’ data is as straightforward as access to two wells’ data. ©

Clarity

Py

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

Ts

Techlog easily handles regular or irregular depth or time reference systems simultaneously.

Attribute data families available for editing by users

Access

Efficiency

From potentially many errors of naming, units and hundreds of wells in a project, families assignment, etc. use powerful data mining tools to rapidly understand the data that are present and any

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.

Variable inventory

Detailed query tools find and repair errors in data names, units, step increment, etc.

Data editing Tp 3DV

Techlog’s powerful data editing tools form an integrated interactive toolkit that allows users to enhance their data and dataset quality effectively and efficiently.

Operations on Data

Several editors have been developed to facilitate access to data of different types for numerical editing. Variable and zone editing are also fully supported within the graphical display tools.

Operations on Datasets Datasets are logical groups of curves held to a common reference. Many operations can be performed on one or more datasets at a time; for example: • trim raw data to interval of interest • combine many datasets for further focussed processing

Clear tabular control eases complex processing on entire datasets (combine and resize datasets)

Data processing Tp 3DV

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.

Graphical 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

Py (splicing), despiking, smoothing, interpolating and standardising your data right off the plot.

Ts

Graphical methods allow the analyst to keep control of the process.

Depth shifting Despiking

Powerful Handle large amounts of data at the same time, for example: • merge/splice or resample whole datasets

The powerful data management tools enable rapid access to relevant curves even in the most complex projects.

Introduction

What Techlog provides

TM

Python 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 database implementations. 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.

TM

Techlog Python editor combined with “libraries” that permit access to:

Ts

©

• 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)

TM

How to use it

• Additional tools and library functions through Internet access from the Python community

• Techsia has provided a large • Scripts can be run “standnumber of ready-made alone” directly from the scripts that accomplish many Python editor; any script tasks; these can be used can access other scripts as as completed, functioning “sub-routines” scripts or as starting points for adaptation to a specific task of interest

TM

• Scripts can be used to access previously compiled code written in C++ or Fortran, for example

• 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

Hierarchical clustering:

Decision Tree:

• find similarities between wells

• powerful classifiers where inputs are mixed and incomplete variables (qualitative and quantitative)

• group wells together • if necessary, align data responses using sophisticated Gaussian analysis, group-bygroup amongst wells

• rank inputs by their information gain • deduced rules can help to understand the input data

Py

• Linear (RMA, Major Axis, x/y, y/x), • Fit lines may be calculated for non-linear, polynomial algorithms user-defined subsets of data are available using the data selection tools and interactivity between viewers • Regression and other fit lines and functions may be created and conditioned on filters, zonation, well-by-well or multi-well

Ts

• Regressions can be freely calculated or forced through a fixed point on a plot • Input user defined-equations graphically and by keyboard entry

• results are displayed in a dendrogram

• Principal Component • Linear Discriminant Analysis (PCA) is a Analysis (LDA) is used useful tool to summarise to determine the best data, since it separates projection space to the dominating features discriminate between in the dataset 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 vs predicted curves) or be of dissimilar type (geology vs petrophysics)

• 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 Correspondence analysis formatted report
