INTRODUCTION

This was the first well drilled on the Beta structure of block

34/10. The primary objective was to evaluate possible

hydrocarbon accumulations in the Middle Jurassic Brent

sandstones. The secondary objective was the Lower Jurassic

Dunlin and Statfjord sandstones.

The purpose of this report is to give an evaluation of the

petrophysical properties of the Brent Group using electrical

logs and core data. The Dunlin and Statfjord sandstones were

considered not hydrocarbonbearing and were not evaluated.

SUMMARY

Hydrocarbons were encountered in the Brent sands (2684.5 - 3000 mRKB), mainly in the Tarbert and Ness Formation. The logs

indicate a gas and oilbearing sand with a net pay of 122.5 m.

The Hnetpay/Hgross ratio is 0.53 in the hydrocarbon-bearing

interval ( 2684.5 - 2914 mRKB ) , The Hnetpay/Hnetsand-ratio is

0.94. The sand has a average porosity of 22.5% and the- netp pay of 23%. The water-saturation in the pay-zone has an average of

27%.

The core porosity over the interval 2684.5 - 2965.54 mRKB, is 20% (the log porosity in this interval 17%). The log and core

porosity agrees well as a general rule, with only a slight

difference due to the overburden effect.

The FMT pressures indicates an oil-water contact at about 2914

mRXB - + 5m, which seems reasonable according to the log evaluation. The FMT-pressures suggest an gas-oil contact at

about 2862 - + 12m. (ref. FMT Report, Well 34/10-17, October 1983, Engineer Per Seim. ) Drillstemtests (ref. Well Testing Report,

34/10-17, Jan. 1984) performed in the Ness and Etive Formations

showed that the reservoir contained water, oil and gas.

LITHOLOGY

Brent Group (2685 - 3000 mKB)

The Tarbert Formation (2685 - 2717 mKB)

The Tarbert Formation is composed of sandstone interbedded by

shales and some minor coal streaks. The sandstones consist of

quartz. The upper sandstone unit is typically medium to coarse,

well sorted, containing no calcareous cement or matrix. The

lower sandstone comprises a fine to medium grainsize,

occasionally very fine, well sorted, micaceous, generally

argillaceous with pyrite.

The shales are black, very carbonaceous with occasional mica and

pyrite inclusions.

The Ness Formation (2717 - 2934 mKB)

The lithology of the Ness Formation is characterized by good

sand layers with visual porosity, interbedded by shales and

coal. The sandstones generally described as quartz, very fine

to medium, predominantly very fine to fine, predominantly non

calcareous. The deeper part of the unit shows an increasing

degree of clay cementation, with traces of silica cement.

Layers of mica are common as well as fragments of coal. Pyrite

and glauconite are found as traces, particulary in the deeper

section of this unit.

The shales also have a good organic content in places and traces

of microcrystalline pyrite and mica are common.

The Etive Formation (2934 - 2936.5 mKB)

The Etive Formation is composed of a very fine to finely

grained, occasionally medium sandstone with well sorted quartz

grains. This unit contains less mica and has good visual

porosity.

The ~annoch Formation (2936.5 - 3000 mKB)

The lithology of the Rannoch Formation is a massive sandstone

unit with minor interbeds of siltstone. The sandstone is a

clear quartz sandstone, very fine to fine grains, occasional

medium to coarse, with slightly calcareous cement. The

siltstone has traces of microsrystalline mica. The siltstone

beds are described as having less calcareous cement. Good

visual porosity is seen throughout the unit.

LOG QUALITY

In general the logs are of good quality but there are certain

things one should consider before evaluating the logs,

Due to sticking the density and neutron log is less accurate in

the interval 2855 - 2875 mRKB. The GR from the

DIFL-BHC-Acoustic log is used in this particular interval, The

caliper from the DLL is preferred, since the caliper from the

Densilog, Neutron and GR is reading slightly too high,

The caliper of the DIFL-BHC-Acoustic log is 0.3 too high. There

is also slight sticking on this log but with no or little

influence on the logs. The Densilog, Neutron and GR is depth

shifted to match DIFL-BHC-Acoustic log. In addition there are

large washouts down to 2685 mRKB.

INPUT PARAMETERS

Formation Temperature

,

When corrected for borehole conditions the maximum temperature

of the particular logging run was used. The formation

temperature for later calculations, 92Oc, was obtained from

the logs.

Formation Water Resistivity (Rw)

A value of 0.079 ohm at 92 OC was chosen from the result from

a watersample from DST no.1. and controlled by calculations

with Rwa, ratiomethod and SP. This is equivalent to a

salinity of approximately 34000 ppm NaC1.

Mud Properties

The following values are reported by Dresser Atlas (Dual

Laterolog, Micro Laterolog, Gamma Ray, run no.1, 01.05.83):

Rm 0.330 o h m at 25.6OC

Rmf 0.177 o h at 22.2OC

Rmc 0.650 ohmm at 23 .gOc

This is equivalent to:

Rm 0.140 ohmm at 92'~

Rmf 0.072 o h m at 92'~

Rmc 0.260 o h at 92OC

Hydrocarbon Density

The densities from the FMT report were used:

gas gradient: 0.149 g/cc 7 U

oil gradient: 0.61 g/cc

In the waterbearing zones a HC-density of 0.8 g/cc of possible

residual hydro-carbons, was assumed.

True Resistivity (Rt and Rxo)

The dual laterolog, corrected for invasion effects, is used for

Rt determinations in the hydrocarbonbearing zone.

The induction log is used in the waterbearing zone below the

assumed water-oil contact at 2914 mRXB.

The RMLL, corrected for mudcake effects, is used as a Rxo

curve.

Shale Parameters

The shale parameters were picked from crossplots, histograms and

visual inspection of the logs. The parameters from the Dunlin

Group were dominating.

RhObshale Neutronshale Rshale 2650 - 2701 mRKB 2.36 0.44 2.2

2734 - 2850 mRKB 2.56 0.50 2.2

2850 - 2914 mRKB 2.52 0.44 2.2

2914 - 3010 mRKB 2.52 0.44 2.5

COMPUTATIONS

Shale Volume

The Density/Neutron crossplot and the GR are the main shale

indicators, but supplemented with the Sonic/neutron crossplot

( A tsh varying from 107 - 85 P sec/ft) or/and the Thorium or Thorium/Potassium curve in some sections.

The final shale volume used for further computations is picked

as the minimum,

The Tarbert and Rannoch sands caused some problems because of

mica content. In addition the Rannoch Formation contained some

zirkon enriched layers.

Porosity

The porosity is calculated with a complex lithology model using

density and neutron logs with following matrix parameters.

RHOB PHIN

Quartz 2.65 -0.035

Heavy mineral 2.83 0.20

Fluid 1.0 1.0

The Ness Formation

Quartz : 2.68

The heavy mineral (assumed to be muscovite) value is picked from

tables over log responses.

An exception from this model is the Rannoch Formation where a

limestone-sandstone model was used with following matrix

parameters.

RHOB PHIN

Quartz : 2-65 -0.35

Limestone: 2.71 0.00

CORE AND LOGDATA COMPARISONS

Crossplots were made in order to evaluate the relations between

the log and core parameters. The calculations are based on the

least square method. The results are:

PHIF = Final log porosity

PORHE = Helium core porosity

KLH = Horizontal core permeability

KLV = .Vertical core permeability

Comment The core porosity/permeability are not corrected for the

overburden effect.

9.00.03 16

LOG PERMEABILITY

The "KLOGH1' and the "KLOGV" curves are not pure log-calculated

permeability. Into the relationships between PORHE and YLH/KLV,

obtained by crossplots, we substituted the log porosity PHIF and

calculated the KLOGH/KLOGV values . These curves were created

due to cosmetic reasons.

DISCUSSION

The main problem in this well is the content of mica and heavy

mineral in the Tarbert and Rannoch Formations. The difference

in core and log porosity at some minor intervals is due to this

content. The Thorium and Thorium/Potassium curves from the

Spectralog were used with varying success and only included in

the shale computations in minor intervals of the Tarbert and

Rannoch Formations.

In general the log and core porosity of the sands agree well

with only a difference due to the overburden effect.

In the sand at 2870 mRKB, two meters of high porosity sand were

lost due to sticking problems. An assumed porosity was given.

Some coalbeds, displaying core porosity, were given assumed

porosity values, but in general the coal porosity and

hydrocarbonsaturation were filtered to give the value 0. These

coals are believed to be non-productive.

Dresser Atlas is a fairly new company working for Statoil and

have some differences of borehole corrections etc. which our

log-analysis system is not adapted too.
