("UKOG" or the "Company")
Oil Seeps from Kimmeridge Limestone Core Samples at Broadford
Bridge-1 Kimmeridge Exploration Well, PEDL234 Licence, Weald Basin,
UK
UK Oil & Gas Investments PLC (London AIM and NEX: UKOG) is
delighted to announce that mobile light oil has been observed
seeping from open natural fractures in Kimmeridge Limestone 4
("KL4") core samples at its 100%-owned Broadford Bridge-1 ("BB-1")
exploration well. The KL4 samples, at a measured depth of around
4080 feet, exhibit a strong oil odour plus the rock matrix is oil
saturated and heavily oil stained. Wet gas readings also increased
significantly at the top of the KL4. Both the KL4 and overlying
shales exhibit a high degree of natural fracturing. Coring
operations continue through KL4.
The well remains on schedule and under budget.
The 160 ft of core taken to date in the Upper Kimmeridge Shales
and Limestones will be transported to Aberdeen today for initial
rock sampling at the weekend, before extensive geological,
petrophysical and geo-mechanical analyses will be carried out by
COREX and Premier Oilfield Laboratories in the UK and USA.
Stephen Sanderson, UKOG's Executive Chairman commented:
"I am privileged and excited to have seen, smelt and touched the
oil in the KL4 samples today, alongside UKOG's management and
operations team. This is a significant and positive result at such
an early stage in the well.
Whilst this is still early days, the presence of mobile oil
within a Kimmeridge geological feature that has no structural oil
trapping configuration, demonstrates that both BB-1 and Horse
Hill-1 could be part of the same Kimmeridge continuous oil deposit.
This oil deposit may therefore extend over 30 km from north to
south across the Weald Basin.
We will now continue our coring and drilling programme and then
move to an extended flow testing operation upon the grant of the
remaining necessary regulatory permissions."
About Coring
Coring is a drilling technique that involves using a
doughnut-shaped drilling bit to capture or "cut" a continuous
cylinder-shaped core of undamaged in-situ rock. The core is
captured in a steel pipe or "core barrel" above the core bit. Core
is normally cut in 30 feet lengths, or multiples of 30 feet, and in
the case of BB-1 with a diameter of 4 inches. Core is taken in
petroleum reservoir rocks for detailed laboratory analyses of
petrophysical and geomechanical parameters and of any hydrocarbons
contained within the rock.
About BB-1
BB-1 is located near Billingshurst, West Sussex, within the 300
km(2) PEDL234 licence, in which the Company has a 100% interest via
its ownership of the licence's operator, Kimmeridge Oil & Gas
Limited. The well, an exploration step-out, is designed to
penetrate four naturally fractured Kimmeridge Limestone units
(KL1-KL4), the uppermost two units of which flowed at record rates
in the Horse Hill-1 discovery near Gatwick Airport.
Importantly, to prove that the Kimmeridge Limestones lie within
an extensive continuous oil deposit the BB-1 well was deliberately
designed to test a feature with no structural closure at the
KL1-KL4 horizons.
The forward plan is to continue to core the KL4 and KL3 target
zones and then continue to drill 8 1/2 " diameter hole at a
constant inclination of 54 degrees to vertical. Further core may be
taken in KL2. The planned overall horizontal deviation of the well
is approximately 1 km. The Kimmeridge Limestones are expected to be
encountered at a drilled depth of approximately 1250-1700 metres,
which equates to around 950-1200 metres vertically below
surface.

Glossary:
casing heavy gauge steel tubing designed
to line the wall of a well. The
casing provides a safe controlled
space in which the drill pipe and
bit can operate in isolation from
conditions in overlying rock units.
The steel tubing is bonded to the
surrounding rock by impermeable
concrete, known as "cement"
--------------- ------------------------------------------
core or coring a drilling technique that involves
using a doughnut-shaped drilling
bit to capture or "cut" a continuous
cylinder-shaped core of undamaged
in-situ rock. The core is captured
in a steel pipe or "core barrel"
above the bit. Core is normally
cut in 30 feet lengths, or multiples
of 30 feet, and normally with a
diameter of 3.5 or 4 inches. Core
is taken in petroleum reservoir
rocks for detailed laboratory analyses
of petrophysical and geomechanical
parameters
--------------- ------------------------------------------
continuous a petroleum accumulation that is
oil deposit pervasive throughout a large area,
or resource which is not significantly affected
deposit by hydrodynamic influences and
is not trapped by structural or
stratigraphic geological conditions.
The petroleum in these accumulations
is normally found within the rocks
where the petroleum is generated,
i.e. within rocks lying within
petroleum source rocks, normally
organic rich shales such as the
Kimmeridge Clay Formation
--------------- ------------------------------------------
discovery a discovery is a petroleum accumulation
for which one or several exploratory
wells have established through
testing, sampling and/or logging
the existence of a significant
quantity of potentially moveable
hydrocarbons
--------------- ------------------------------------------
limestone a sedimentary rock predominantly
composed of calcite (a crystalline
mineral form of calcium carbonate)
of organic, chemical or detrital
origin. Minor amounts of dolomite,
chert and clay are common in limestones.
Chalk is a form of fine-grained
limestone
--------------- ------------------------------------------
naturally a fractured reservoir contains
fractured open and usually connected cracks
reservoir or fissures within the rock matrix;
fractures can enhance permeability
of rocks greatly by connecting
pore-spaces together; naturally
fractured reservoirs have been
created over geological time by
nature, not man-made via hydraulic
fracturing
--------------- ------------------------------------------
step-out well a well specifically designed to
determine the lateral extent of
a discovered hydrocarbon accumulation
or play
--------------- ------------------------------------------
wet gas natural gas, predominantly consisting
of methane (C1), ethane (C2) and
propane (C3) but also containing
the longer molecular chain natural
gases butane and iso-butane (C4),
pentane and iso-pentane (C5). The
C4 and C5 gases are created during
oil-generation within a petroleum
source rock unit when oil is thermally
cracked. At Horse Hill these natural
gases lie in solution with the
oil in the KL3 and KL4 Kimmeridge
Limestone reservoirs (i.e. solution
or associated gas and not as a
separate free-gas phase).
