NW Razzak Block
(6) Northwest Razzak Block
Introduction
The Northwest Razzak block is located in the northern part of the Western
Desert of Egypt, within Matruh and Shushan Basins; they are mainly of
Jurassic to Early Cretaceous origin in which the sedimentary cover exceeds
25.000 ft with extension to the offshore area.
The Northwest Razzak block occupies a current area of 4764 km2 and has
12645 km 2D seismic lines and 1485 km2 3D seismic, it comprises 42 wells
drilled by different companies.
Hydrocarbon Potential:
1- Source Rock and Maturity
The geochemical analyses carried out on several wells located in the area,
have confirmed the presence of potential source rock within the Khatatba
and the Lower Alam El Bueib Formation.
Several intervals within the Khatatba Shale contain fair to good source
rocks of type III and mixed type II / III, which have potential for oil and gas
generation. Measured TOC are up to 2.56% while the hydrogen index varies
between 165-526.
The geochemical analyses carried out on the basal part of the Alam El Bueib
Shales of several wells in this area, indicated the presence of mainly type III
and some contribution of type II kerogens with a TOC that varies from 0.56%
to 3.8% and a hydrogen index ranging from 140 to 265.
The burial/maturation curves of several onshore wells which have been
modeled and calibrated based on the corrected bottom hole temperature
and measured vitrinite reflectance for the khatatba and the Lower Alam El
Bueib source rocks, have elucidated that khatatba and most of the Lower
AEB source rocks reached mid oil generation stage during the Late
Cretaceous/Early Tertiary.
However, Oil to source correlation which has been carried out on Khatatba
and AEB source rock extract samples of the Marakia-1, Almaz-1, Razzak-13
well and the oil samples from the Alamein/Razzak fields and Marakia-1 well
indicated that the oil samples are most likely sourced from Khatatba source
2
NW Razzak Block
rock. The AEB source rock can be considered as a secondary contributor for
hydrocarbon generation in the area.
2- Migration, Trap and Charge Timing
The North Alamein-1x discovery which is located 10 km W. of Dahab-3x,
indicates that migration from the underlying mature source is most probably
vertical and/or along the main boundary faults of the structure. The oil
generation from the Khatatba source rock coincides with the timing of the
last tectonic event (Late Cretaceous/Early Tertiary) affecting the trap
formation.
In the eastern part of the block where the deepest part of the basin,
significant amount of gas might have been generated from the Khatatba
source whereas oil could have been expulsed from the Lower Alam El Bueib
shales.
3-Seal
The Dahab formation which mainly consists of shales with some carbonates
beds and thin streaks of sandstones, is the top and side seal for the Alamein
Dolomite reservoir and even for the top of AEB#1 reservoir.
In the case of the Dahab-3x location, presumably, the side seal potential is
provided by the closing fault which might have been sealed by shale smear
as consequence of the strike slip movements.
For the Bahariya sandstones, top/side seal should be provided by the
carbonates/shales of the overlying AR#G section.
Lateral sealing due to the juxtaposition of porous sand bodies against tight
shaly and carbonate intervals. Fault gouge and clay smearing is a possible
fault plane sealing mechanism.
4-Reservoir
a- Alamein Dolomite (Primary Objective)
The fractures and the dip analysis carried out over the Alamein section using
FMI and open hole porosity logs indicate the presence of an upper porous
zone of relatively higher conductive response, characterized by a low density
of open fractures but with abundant vuggy and micro-vuggy porosity of
good connectedness.
3
NW Razzak Block
b- AEB # 1 Sandstones (Secondary Objectives)
The Alam El Bueib-1 sandstones were considered as secondary objective and
in particular the first sandstone package at the top part of the section which
proved to be hydrocarbon bearing reservoir in N. Alamein-1x.
c- Dahab Sandstones (Secondary Objectives)
The Dahab sandstones were also considered as an additional secondary
target after a reasonable hydrocarbon flow rate as observed in N. Alamein-
2x and N. Alamein-1x.
d- Bahariya Sandstones (Secondary Objectives)
In the Dahab-1x well, poor oil shows were reported while drilling parts of the
Cenomanian (AR#G / Bahariya) section; porosity were considered as possible
secondary target in the area.
Summary of the Wells:
NTRK-B-1X well (2010)
NTRK-B-IX reached a total depth of 15820' (MD)/-14985' (TVDss) in the
Lower Safa member of the Khatatba Formation. While drilling, oil and gas
shows were encountered in the AEB-5, and Upper Safa sandstones beside
Masajid Dolomite. The well encountered no reservoir quality facies (avg. Phi
at both AEB-6 & Upper Safa reservoir target < 8%). Petrophysical evaluation
indicated a net pay of 1.5 feet in Masajid dolomite, 2.5 feet in the Upper
Safa & 1.5 feet in the Lower Safa Sandstones. No zones of interest Identified
on logs. Wireline tool could not reach TD due to ledges. LWD logs
(GR\NEU\RES) was used to evaluate the well from TD up to depth 14660'.
The well was plugged and abandoned as a dry hole.
Gawad-IX well (2010)
The sandstone reservoir objectives in the Jurassic section were penetrated in
the well, no zone of interest was identified. The well was plugged and
abandoned as a dry hole. Likely due to the lack of sufficient side seals
analysis. The biostratigraphic analysis of the main seismic events indicated
the absence of the expected Paleozoic section in the area, where the Jurassic
is directly overlying the basement.

NW Razzak Block
WMED-A-IX well (2010)
Structurally WMED-A-IX well is located on the east-west trending Almaz
High (Dabaa Platform) and was mapped as a four-way dip closure on the
Bahariya, Kharita and Jurassic structural levels.
While drilling oil and gas shows were encountered in the sandstones of AEB-
3A, AEB-3C and 3D/E. Petrophysical evaluation indicated 12 ft of net pay in
the AEB 3D/E sandstone. After setting 7" liner, one DST was performed over
the AEB 3D/E Member (Perforated interval 10299' -10323') and recovered
25 bbls (2% Oil & 98% Water).
The well was plugged and abandoned as a dry hole with non-commercial oil
after reaching a TD at 12,650 ft in Basement.
WKAN-B-IX well (2007)
Structurally WKAN-B-1X well is located on a NE-SW trending fault block at
the Jurassic prospective levels. There may be a small component of 4-way
dip closure at the prospect location.The well was designed to test the
potential of the Lower Safa sandstone as a primary objective (including pre-
Wadi Natrun sandstones) and the Upper Safa and AEB-6 sandstones as
secondary objectives.
WKAN-B-1X well reached TD at 16,300'. While drilling oil and gas shows
were encountered in Dahab, AEB-6, Masajid, Zahra, Uppe Safa and Pre-
Wadi Natrun sandstones.
Petrophysical evaluation indicated a pay within the AEB-6 and possible pay
in the Masajid. Although good oil and gas shows were encountered in
Khatatba Formation, No convincing pay zones appear due to bad hole
condition which affected on log measurements.
After WKAN-B-1X reached a total depth of 16,300', in Pre-Wadi Natrun,
three cement plugs were set. Three DST's were performed, two over the
Masajid Formation with recovery of formation water, and one over the AEB-
6 {interval: 11905'-12028' (Actual Perforated 50')} with recovery of 942
BOPD and 0.21MMSCFGD after fracing and by nitrogen lifting.
The well is considered an AEB - 6 oil discovery.

NW Razzak Block
Tourmaline-lX well (2006)
The well bottomed in Alam El Bueib at 11,400', with oil shows in Dahab,
Kharita and Alam El Bueib sands and Alamein Dolomite. The well tested the
Alamein Dolomite and recovered formation water. The well was plugged
and abandoned as a dry hole.
Umm Habib -2 well (2006)
The well was planned to test the hydrocarbon bearing potential of the
Alamein Dolomite as the primary objective and Alam El-Bueib Sandstones as
a secondary objective (these sands having been previously tested in the
North Razzak field approximately 1250 m southeast and across a syncline
from the Umm Habib-2 structure).
No hydrocarbon shows or fracturing were encountered in the primary
objective Alamein Dolomite. Minor oil shows were observed in sandstone
layers of the secondary objective; Alam El Bueib Formation.
Wireline log analysis proved the primary and secondary reservoirs targets to
be water wet, with no observed hydrocarbon accumulations.
Based on wireline log analysis the Umm Habib-2 was plugged and
abandoned as a dry hole.
Post well analysis and mapping suggests that the structure drilled may post-
date the main hydrocarbon expulsion phase from the basin, coupled with
low fault seal integrity and therefore high trapping potential risk.
Washka South -1 well (2006)
The primary objective was the Cenomanian Bahariya Sandstone and the
Aptian Alamein Dolomite. The Dahab and Alam El-Bueib Sandstones were
the secondary targets and lie on the downthrown side of the fault closure.
The well had minor oil and gas shows in the secondary objective sandstones
of the Dahab and Alam El Bueib formations.
Wireline log analysis proved the well to be water wet. Only residual
hydrocarbon bearing formations were observed in secondary objectives.
No tests were performed, and the well was P&A as a dry hole.

In overall conclusion it is believed that the lack of hydrocarbons present at
this well location is due to the structural trap post-dating the optimum
hydrocarbon migration phase during late Cretaceous. Alternatively the
structure may have been bypassed/in migration shadow.
Washka SW -1 well (2006)
Washka SW-1 reached a T.D. of 6166 ft in the Cenomanian Lower Bahariya
sandstones.
The primary target of the well was to test Cenomanian sandstones of the
Bahariya Formation on the up thrown side of the southern boundary fault
that was encountered by the Dabaa-3 well. The Cenomanian Abu Roash /G
carbonates were the secondary target. The Alamein Dolomite Formation
had already been tested on the up thrown side of the fault by the Dabaa-3
well and proved to be water wet.
The well had oil and gas shows in the Cenomanian Abu Roash "G" limestone
and Cenomanian Bahariya Formation sandstones.
Log analysis proved the presence of oil in thinly bedding sandstones of the
Bahariya Fm. with an average porosity of 18.7% and average SW of 84%.
MDT pressure data revealed a water gradient with a value of 0.43 psi/ft in
the sandstone of the Bahariya Fm. Three MDT samples were recovered and
proved to be heavy and black oil (residual oil).
Based on log analysis and MDT pressure results Washka SW-1 was plugged
and abandoned as a dry hole.
S. Dabaa 8- -1ST well (2004)
The well was drilled as a vertical well to the top of Masajid Dolomite where
a sever loss of circulation zone was encountered. Later the hole was drilled
as a deviated well to a total depth of 9,518 ft (Paleozoic Basement). The
open hole logs have revealed no hydrocarbon potential in the reservoir
sands of Khatatba, Bahrein and Paleozoic sections. Therefore the well was
plugged and abandoned as a dry hole.

Mas-lX well (2003)
The well bottomed in Alam El Bueib #3 at 10,102', with oil shows in Alam El
Bueib sands. Mas-1x well tested the Alamein Dolomite and recovered 745
BOPD, with 136 BWPD. The well was temporarily abandoned.
Zomorod-lX well (2002) The main objective was to test the Alamein dolomite, AEB-1 and Bahariya
sandstone reservoirs on a low relief three way dip closure. The well
bottomed in Alam El Bueib at 9,230'. No oil or gas shows were encountered
in the drilled section.
The well was plugged and abandoned as a dry hole. The absence of
hydrocarbon in the well is most probably due to lack of charge for the
Zomorod low side fault closure.
Marina W-1X well(2001)
The main objectives were to test the Alamein dolomite & AEB-1 sandstones. While drilling, the well had traces of oil and gas shows over Kharita sandstones, Dahab sandstones, Alamein dolomite and AEB sandstones.
Petrophysical evaluation indicated 5 feet of net pay in Kharita with average
porosity of 20% and average water saturation (SW) of 44% and 27 feet of
net pay in AEB#3D with average porosity of 13% of average SW of 40%.
One cased hole test was conducted over two intervals within AEB-3D
sandstones recovered formation water and traces of oil by N2 lifting. Based
on this test and evaluation results, the well was plugged and abandoned as
a dry hole.
The absence of hydrocarbon accumulation in marina west-1x is most
probably due to a limited charge and poor reservoir quality.
Onyx -1X well (2000)
The main objectives were to test the Alamein Dolomite & AEB-1 sandstone
reservoirs at the optimal position of a horst block which is believed to be the
western structural extension of Akik-1x closure (Gas/Condensate discovery).

NW Razzak Block
During drilling operation, the well had traces of oil and gas shows over
Kharita sandstone, Dahab sandstone, Alamein Dolomite and AEB-2
sandstone.
Petrophysical evaluation indicated 17 feet of net pay in Alamein Dolomite
Fm. with average porosity of 8% and average SW of 27%.
Cased Hole DST conducted over the upper part of Alamein Dolomite:
Perforated intervals: 8775' - 8760' (15') by N2 lifting recovered small
volume of formation water (Sal. 97,000 ppm Nacl) with no oil or gas shows.
Add perforated intervals: 8745' - 8775' (30') by N2 lifting recovered
formation water (Sal. 100,000 ppm Nacl) and N2. After Acid Job recovered
formation water and N2.
Based on Onyx-1x evaluation and test results the well was plugged and
abandoned as a dry hole.
The presence of Onyx structural closure below the extrapolated OWC
defined in Akik-1x gas/condensate discovery is most probably the main
reason for the absence of hydrocarbon accumulation in Onyx-1x structure.
Washka -2X well (2000)
Open hole test was conducted over the 47' in Alamein Dolomite recovered
270 bbl brine + 10 bbl oil.
Based on hydrocarbon shows and the petrophysical evaluation, which
indicated 62' net pay in Alamein Dolomite, three intervals tested over the
Alamein Dolomite Fm as following (Cased hole DST):
1- Perforated intervals: 7906' – 7918' (12'), By N2 lifting recovered oil for 15
min only then N2. After acid job, lift the well with N2, No flow.
2- Perforated intervals: 7918' - 7952' (34'), By N2 lifting recovered : Minor
amount of oil + 90 % water.
3- Perforated intervals: 7952' - 7966' (14'), By N2 lifting no flow, after acid
job well lifted with N2, Recovered oil (23.4 API)+ 80-95% W.C. (sal.
165.000 ppm Nacl) with fluid level close to surface.

Dahab-3X well (1998)
The Dahab-3X was designed to test Dahab structure at Bahariya (2ry) and
Alamein Dolomite (1ry target) levels which was previously drilled by the
Dahab-1X well in a down flank position.
Due to the presence of vugy interval and the presence of weak oil shows, it
was decided to conduct an open hole drill stem test. Set packer at 10474', to
flow to surface and the well reversed out water. The well plugged and
abandoned as a dry hole.
Dabaa -3X well (1992)
The well had a primary objective of testing the AEB-3A & 3E reservoirs. The
secondary objective was believed to exist within AEB-5 sandstone. Dabaa -
3X well was drilled to a total depth of 10500', in the Alam El Bueib
Formation with weak oil shows in the Bahariya, Kharita and AEB-3D
formations. After evaluating the wireline logs it was decided to plug and
abandon the well as a dry hole.
Ie 33-4 "El Garf -2X" well (1988)
The well was recommended to be drilled in order to test the hydrocarbon
potential of the so called "Garf updip" structure, 2.5 kms to the NW of Garf-
1X well which was drilled by WEPCO in 1974 and was abandoned with oil
shows in the Cenomanian reservoirs. New seismic lines showed, on the other
side a culmination to the NE of Garf-1X location, where the "oil leg" was
expected to be found higher. Log interpretation showed several oil bearing
intervals totaling 19 ft., a test was run in the interval Bahariya Fm. and 3
bbls of heavy oil were recovered. The well was suspended as oil producer
after re-evaluation.
Washka -1X well (1971)
The well was drilled in 1971 by Wepco and reached TD in AEB-1. Washka-1x
was drilled based on 2D seismic maps showed that washka-1x location was
the optimum position of the structure. Oil shows recorded over the Abu
Roash/G Dolomite, Alamein Dolomite and AEB-1 sandstones.
10
NW Razzak Block
The well experienced a complete loss of circulation over the middle part of
the Alamein Dolomite and partial losses within the Abu Roash-G Dolomite.
No tests were carried out in any of the interval with shows.
Lack of adequate side seal across the fault closure is the main reason for the
absence of hydrocarbon accumulation in the structure.
Dahab-1X well (1970)
The primary objectives were the Alamein Dolomite which suggests some
reefal buildup over the crest of the structure and the sandstone immediately
underlying the Alamein Dolomite. The secondary objective was the
Cenomanian carbonate and clastic.
Hydrocarbon shows were recorded while drilling the Abu Roash/G, Bahariya,
Alamein and Alam El Bueib#1 Formations.
Two DST were carried out as follows:
1- Lower Cretaceous Alamein Dolomite (11025ft-11120ft), recovered 142 bbl
of formation water (103.000 ppm cl-).
2- Alam El Bueib-1 sand stone of L. Cretaceous (11448 ft-11528 ft),
recovered 111 bbl formation water (111.000 ppm cl-).
Therefore, the well was plugged and abandoned as dry hole. It is concluded
from the study that the prospect was structurally low.
