FOREWORD
This is a project proposed to NPD and to the main Oil Companies operating in Norway. The
aim of the project is to create a sound data base of the borehole images logs (i.e., electric as
FMS, FMI, STAR, EMI &/or acoustic as UBI, CBIL, CAST...and density images) available
in NPD, &/or available in companies.
It is intended to QC and process the data, and to generate images in an appropriate format
(cgm-file) with a quick study aiming to deliver the key results, the whole output in CD-
media.

1. INTRODUCTION

Borehole image data (electrical, acoustic and density) are a valuable source to get a better
understanding of the reservoir and therefore to improve oil recovery. The challenges with
these data types are that processing and interpretation are not widely spread among
geoscientists involved in reservoir characterisation. It is often a matter of highly specialised
Geoscientists, implementing specialised software. In addition the results need to be cross-
checked with other data sources. The interpretation needs structural and sedimentological
backgrounds. In other words a lot of intelligence and works need to be invested to get out-put
and data-results that can be quickly and understandable used in further interpretations.
It is well known, in any field of sciences and techniques that more you experience better it is.
This is more accurate in borehole imaging. The author of this proposal (author and co-author
of more than 60 reports, articles...) has accumulated a significant experience in borehole
imaging that can be quickly summarised as following:
       during six (6) years, thirty (30) projects with final reports concerning more than fifty
        (50) wells from different areas were carried out;
       from North Sea –Norwegian and Danish Sectors- (Varg, Svale, Valdemar,
        Lulita/Harald, Dan, and Fram Fields);
       from Qatar (Al-Shaheen Field);
       from Saudi Arabia (Gawar Field);
       from Iran (South Pars and Zagros fields);
       these case studies concern reservoirs where the main challenges are related to
        structural, fracture, matrix and/or sedimentological issues, such as paleocurrent
        directions;
       borehole images data studied are from FMI, FMS, CBIL, STAR, UBI and CAST
        tools;
       experience in the use of software packages: RECALL, GEOFRAME and
        TERRASTATION;
       articles and presentations concerning borehole imaging;
       a book in progress about borehole imaging;
       the whole experience is detailed in the CV appended at the end of this proposal.


From this experience important elements were learned regarding the data, the methodology
used, the main key results needed, and the main ways to present the key results. A quick
introduction to these notions will lead to a presentation of the main objectives of this project.

2. BOREHOLE IMAGING DATA BASE: a complete data base
I noticed that a lot of time was spent in several contacts with colleagues involved in
companies dealing with nearly every project carried out, to collect data in the one hand, and
in the other hand often the data was often incomplete and therefore has to be completed. The

concerned company is often obliged to order once more from the logging company the data,
and often the whole package of data, which means more costs and more time lost.

All that can be avoided from start by recording once for all a complete borehole imaging data
base.
First off, the data of any borehole imaging has to contain in addition to the main imaging data
(conductivity, acoustic and density) the necessary data as following:

       orientation data of the log images;
       caliper log;
       log survey of the borehole;
       the GR of the image-log run;
       the GR from another wireline-source;
       main and repeat sections;
       reservoir zonation;
       corephotos are very useful and other wireline logs.


3. DATA QC-ed, PROCESSED and IMAGES GENERATED: it is not a
big deal of job to be added

Once the data is loaded there is not a big deal of specialised job to be done to QC the data, to
process it and generate the images.
QC-ing data is a process that has to be done in several stages of the process from loading to
the final interpretation. First off, QC-ing image log data should be done while and just after
finalising the loading task. A second QC-ing step is to check with the survey logs from other
sources, another QC-ing will follow after processing and the following one once the images
are generated. Finally, once the results of the interpretation will be integrated with other data
while modelling the field.
A QC report will mention the main key features of the data and will give a final statement
about the image quality.
The main parameter used for processing and for generating images has to be reported and
kept for the same reservoir to consistently make it easy for the correlation.


4. KEY RESULTS ADDED TO THE DATA BASE: they are considered as
data for other inputs

For several geoscientists from borehole imaging logs there are a couple of result-data they
need as an input for further processing and interpretations. It is possible to add theses result-
data with the borehole images data.
It is well known that image logs is a continuation of dipmeter data and so they are run at least
to get dip measurement. In this respect, there are two notions important to get at hand as a
result-data: paleohorizontal dip and the structural dip.
The paleohorizontal dip is very important for the paleocurrent directions and for structural
purposes. It is considered to illustrate the rotation or the uplift of the geological formations
since they deposited. The methodology applied has to be described in details, because it is
related to the interpretation of the area of the well, which is very linked to the sum of

knowledge and data accumulated at the moment. This interpretation generally changes in the
future, since more data will be added.
The structural dip can be used to correlate with seismic and/or for construction of cross
sections. It concerns the formations and/or specific horizons. The methodology used has also
to be described.
In addition to these main results it is useful to give a quick glance to the following key
features, without details, just to inform that they are available and if needed it is possible to
carry out further study, including a systematic picking of the concerned planar features. It is
about: faults, fractures, the matrix and the paleocurrent directions. What it is useful and
quickly done is a zonation indicating intervals of interest with the presence of these features.
The final key feature to be added is the presence of in-situ stress features (borehole breakout
and induced tensile fracture), using an appropriate zonation of the borehole images and an
appropriate track plotting the calipers.


5. MAIN CHARACTERISTICS OF THE PROJECT: Software package,
data needed, out put delivered, timing and cost

Software package:
The project will be carried out implementing RECALL (already available in Saadallah
Geoconsultant Company). The author has accumulated a significant experience using this
software.

Data and conditions requested as input
Image logs in CD,
Other logs: surveys logs, GR from wireline, reservoir zonation and/or geological zonation,
corephotos are very useful too.
A contact person from the operating team and company of the field is necessary.
The job will be carried out in Saadallah Geoconsultant place (Stavanger).

The output:
In a CD per well containing:
A read-me file (world.doc) describing the contains of the CD,
A composite plot (cgm.file) at scale of 1:10 with specific track: depth, orientation curves of
the borehole and of the tool, shapes of the borehole (with longitudinal and transversal cross
sections), GR from both sources, images, geological planar features picked (sedimentological
and structural), zonation tracks (image quality, reservoir zonation, cross bedding zonation,
fault zonation, fracture zonation, in-situ stress zonation, and specific features related to the
matrix or any interesting feature), and the comment track.
The header of the composite plot will contain the key information: Company-name, field-
name, well-name, top-bottom of the logged section and of the reservoir, formation name, and
main results (image quality, paleohorizontal dip and comment, structural dip and comment,
comment about faults, fractures, matrix, cross bedding, and in-situ stress features).
A summary composite plot (cgm.file) at scale of 1:200 to sum up the information within the
composite plot at 1:10.

Reports about Structural and Fracture studies of Reservoir using BOREHOLE
IMAGES Data done in Z & S Geosciences Stavanger in 1997-1999.

The aims of the investigations were structural and fracture studies of reservoir. I studied about
150,000 ft of electric and acoustic Images logs (FMI, FMS, CBIL and STAR) and petrophysics logs
in different geologic contexts: North Sea, Saudi Arabia and Qatar. The studies were done on UNIX
workstation implementing RECALL software.
The results were reported in 19 reports (with enclosures and illustrations) and I improved the
interpretation by three news methods:

-1) Bedding-Plane-Correlation, to constrain further geologic cross-sections in a reservoir
drilled horizontally

-2) Direction of Maximum Fracturing in a reservoir, defined by stereo-projection to help
finding the best direction for a drill to encounter the maximum fluid flow in a fractured
reservoir,

-3) A new kind of 3D-Structural map, using a fictive surface named well-topography by drawing the
iso-TVDSS curves. I was just attempting to publish this new method waiting for the authorisations of
Baker Atlas Geosciences and the oil company client..

Concerning the specific problem known as “Super-K zones” in Ghawar Field (Saudi Arabia) I
contributed to its study by 8 reports trying to define role of fractures and high porosity layers in high
