Harvey and Elgood licence Updates
Independent Oil and Gas plc ("IOG" or the "Company") (AIM:
IOG.L), the development and production focused oil and gas company,
announces the following updates on its Harvey and Elgood
licences.
Highlights:
-- The Oil and Gas Authority ("OGA") has confirmed the
continuation of licence P2085, which contains the Harvey discovery,
until 20 December 2017.
-- The technical work prepared and submitted by IOG in relation
to its Elgood discovery has also been accepted by the OGA and will
be added to the Blythe Field Development Plan ("FDP") as a
satellite development.
Harvey
If successfully appraised, Harvey has the potential to be the
largest gas discovery in the IOG portfolio and significantly
enhance the economics of IOG's Southern North Sea business. The
range of internal resources estimates are large with a P10, P50 and
P90 range of 44 BCF, 113 BCF and 290 BCF respectively. Harvey is
100% owned and operated by IOG. It is located in the well
understood Leman Sandstone Formation play.
A commitment to drill an appraisal well is required to extend
the term further and IOG would expect to make that commitment later
in 2017. If an appraisal well is successful, Harvey could be tied
back to the same nearby pipeline that the Company has signed an MoU
to acquire to evacuate the Blythe and Vulcan Satellite hubs,
creating valuable economies of scale.
Elgood
Elgood is a relatively small discovery close to Blythe and
contains an internally estimated P50 22 BCF of recoverable gas. It
is expected to be developed via a single subsea well and tied back
to a platform at Blythe. The Field Development Plan is being
prepared with submission to the OGA expected in mid-2017. Both
Elgood and Blythe are 100% owned and operated by IOG.
Mark Routh, CEO of IOG, commented:
"We appreciate the continued support of the OGA with regards to
our Southern North Sea gas portfolio. The excellent technical work
completed by our team on Harvey has confirmed an exciting gas
discovery adjacent to our Blythe and Vulcans hubs and the work on
de-risking Elgood has avoided the need for a further appraisal well
before development. We are making good progress on moving our
Southern North Sea developments forward and related funding and
will provide more updates in due course."

Notes
About Independent Oil and Gas:
IOG is an oil and gas company with established assets in the UK
North Sea. The company's strategy is to deliver near term
development and production assets in North West Europe, through its
extensive technical and commercial expertise, whilst maintaining
some exposure to exploration upside. The company is looking to grow
both organically and through acquisition.
All IOG's licences are owned 100% and operated by IOG.

About the Vulcan Satellites:
The Vulcan Satellites consist of three fields, Vulcan East,
Vulcan North West and Vulcan South, which hold independently
estimated 2C resources of 77.4 BCF, 131.3 BCF and 112.0 BCF
respectively, 320.7 BCF collectively. These fields lie in Block
49/21a (Licence P039), Block 49/21d (Licence P2122), Block 48/25b
(Licence P130) and Block 49/21c (Licence P1915) in the UK sector of
the Southern North Sea. They lie approximately 30-45km east of
IOG's 100%-owned Blythe field and are considered ready for
development with no further appraisal required. The Company is
preparing Field Development Plans for these three fields which will
form a gas hub. IOG has assumed liability for decommissioning a
suspended well on Vulcan East, which in April 2015 was
independently estimated to cost GBP3.0 million as part of a
development campaign, based on prevailing rig rates at that
time.
About the Blythe Hub:
The Blythe hub licences comprise Blythe, Elgood, Hambleton,
Truman and Harvey.
About Blythe:
The Blythe gas discovery in the Rotliegendes Leman formation
straddles Blocks 48/22b and 48/23a in the Southern North Sea in
licence P1736. The Blythe Leman reservoir needs no further
appraisal and has independently verified 2P reserves of 34.3 BCF
(6.1 MMBoe). (Source: ERC Equipoise Competent Person's Report
("CPR") dated September 2013.) The Blythe licence has been extended
to 31 December 2017. The Company submitted a draft field
Development Plan to the Oil & Gas Authority in December 2016.
Subject to completion of the pipeline acquisition, the Company
intends to submit the full field development plan on a combined
Blythe and Elgood development in the first half of 2017.
Gas tested to surface from three separate intervals in the
Carboniferous beneath the Blythe Leman gas discovery from one of
the Blythe discovery wells, 48/23-3 drilled by Arco in 1987. The
maximum rate achieved was 0.9 MMcfd from an unstimulated vertical
test. (Source: End of well report 48/23-3 - November 1987.) This
was deemed uncommercial at the time, before the advent of
horizontal multi-fracture stimulated wells. Further technical work
including seismic reprocessing and remapping needs to be completed
to evaluate this potential resource to refine the gas-in-place
estimates which are between 70 BCF and 310 BCF. (Source: Tullow Oil
48/23a Relinquishment Report - May 2009.)
Oil has flowed to surface from the naturally fractured Zechstein
Carbonates in the Hauptdolomit formation above the Blythe Leman gas
discovery from two wells. Well 48/22-1 drilled by Burmah in 1966
flowed 39deg API oil at rates up to 2,000 barrels per day (Source:
Composite well log 48/22-1 - October 1966) and well 48/23-3 drilled
by Arco in 1987 at flowed 38deg API oil at a maximum rate of 1,128
barrels of oil a day. (Source: End of well report 48/23-3 -
November 1987.) The extent of the structure and potential oil
resources in the Hauptdolomit remains unknown. Previous estimates
considered that the mapped closure was probably small. Oil-in-place
has been estimated between 2 MMBbls and 4 MMBbls. (Source: Tullow
Oil 48/23a Relinquishment Report - May 2009.) Further evaluation
and re-mapping is continuing now that a development will proceed on
the main Blythe gas discovery.
About Harvey:
IOG has a 100% working interest in licence P2085 to the east of
Blythe (Blocks 48/23c & 48/24b) which was awarded in the 27th
licensing round. Recent 3D seismic reprocessing and remapping by
Beagle Geoscience Limited has led to an improved understanding of
the complex faulting that exists in the overlying strata. Based on
this work, the internal management probabilistic estimates of the
P90/P50/P10 gas initially in place for Harvey are 77/176/403 BCF
and probabilistic estimates of the P90/P50/P10 resources are
44/113/290 BCF.
IOG is now considering committing to a firm appraisal well on
Harvey which would be required before a development plan could be
prepared. If an appraisal well was to be drilled successfully and
Harvey was subsequently developed, the Company believes that it
could be tied back to the same pipeline as the Blythe and Vulcan
Satellite hubs.
About Elgood:
IOG has a 100% working interest in licence P2260 awarded in the
28th licensing round to the west of Blythe containing the Elgood
discovery (Block 48/22c). Elgood was drilled by Enterprise Oil in
1991 and tested gas to surface at 17.6 MMcfd but was not progressed
by Enterprise due to size and gas prices at that time.
IOG is now working on the development plan for Elgood to be
submitted in conjunction with the Blythe field development plan and
will commission a CPR to confirm the resources over this area.
Based on the work undertaken by Beagle, the internal management
probabilistic estimates of the P90/P50/P10 gas initially in place
for Elgood are 26/35/48 BCF and probabilistic estimates of the
P90/P50/P10 resources are 15/22/31 BCF.
SNS portfolio:
The probabilistic Gas Initially in Place and resources estimates
for IOG's SNS portfolio of Blythe, Elgood, Harvey and the Vulcan
Satellites are as follows: -

This does not include other discoveries that may be
sub-commercial, or potential additional resources that could be
recovered from the carboniferous sections or other undrilled
prospects in the SNS portfolio.
About Skipper:
The Skipper oil discovery is in Block 9/21a in the Northern
North Sea in licence P1609. IOG owns 100% of the Skipper licence
P1609 and is the Operator. In July/August 2016 the Company
successfully drilled its first operated appraisal well and
retrieved oil samples, in order to design the optimum field
development plan. Skipper has independently verified gross 2C
resources of 26.2 MMBbls. Following the results from the appraisal
well, IOG management's estimates of the oil in place in the Skipper
reservoir are minimum/most likely/maximum 119.3/142.6/168.3 MMBbls.
Recovery factor estimates will be revised during the full field
reservoir simulation studies which are now underway.
