Lansdowne Oil & Gas Snapshot

Lansdowne's portfolio consists of Cretaceous gas exploration and appraisal assets that primarily flank the Kinsale Energy ( PETRONAS) operated Kinsale Head and Seven Heads gas-fields and associated infrastructure. Lansdowne, through the acquisition of Milesian Oil & Gas Limited in December 2007, acquired a substantial position along the basin margin in already identified Jurassic exploration targets with potential for oil and gas. Lansdowne further consolidated its position in the NCSB with the award of a Licence 1/11 giving it, and its joint-venture partner, rights to the proven oil productive horizons beneath the Seven Heads gas-field discovered by the Esso/Marathon consortium in the 1970s. Oil from Cretaceous reservoirs was successfully tested at flow rates of between 1,300 bopd and 1,600 bopd, from three previously drilled wells on what is now called the Barryroe Oilfield. Lansdowne, as a 20% equity partner, recently participated in the successful Barryroe 48/24-10z appraisal well that tested 3514bopd in March, 2012.


Lansdowne has targeted the Irish offshore shallow shelf areas for exploration and exploitation as it considers the proven oil and gas productive NCSB relatively underexplored in the context of the North Sea neighbouring basins. Lansdowne's portfolio of opportunities offers a relatively low-cost shallow water drilling environment that combined with competitive fiscal terms afford a realistic expectation of high returns on investment within the medium term. Lansdowne's in-house knowledge and experience as provided by its management and technical team, coupled with its comprehensive data-base, assures its competitive advantage within the industry in this region.


Lansdowne Oil & Gas Plc continues to pursue its focused approach to explore and develop its licensed areas in the North Celtic Sea basin, off the south coast of Ireland.

The Company continues its strategy of evaluating quality drillable prospects on its licensed areas and combining a long-term exploration programme for commercial oil with near-term exploitation of shallow gas targets. As a result, Lansdowne now holds rights, through its wholly owned subsidiaries, to five Standard Exploration Licences in the Irish offshore.

Standard Exploration Licence 4/07 – “Midleton / East Kinsale”

Licence 4/07 incorporates part-blocks 49/11, 49/12, 49/17 and 49/18 immediately south-east of the Kinsale Head Gas field along the axis of the North Celtic Sea Basin. The licence encompasses an area of 542 sq km and Lansdowne holds a 20% interest. This licence contains the Midleton gas discovery and the East Kinsale gas prospect.


Midleton  lies approximately 20 km northeast of the Kinsale Head gas field (c. 1.7 TCF reserves) and also 20km to the east of the Ballycotton gas field (c. 60 bcf reserves).
It was drilled by the 49/11-3 well in the summer of 2015.
Good quality reservoirs were found in the Greensand and Upper Wealden formations of the Lower Cretaceous.
Gas was found in the Greensand, but the volumes were not considered commercial and the well was plugged and abandoned.
Post well evaluation studies are continuing and the results will be integrated to assess the impact on the other gas prospects in the portfolio.

East Kinsale Prospect

The East Kinsale Prospect area lies some 15 to 20 km to the east of the Kinsale Head Field (c 1.7 TCF reserves) and immediately to the north of the Old Head gas field, established recently by the 49/23-1, 49/23-2 and 49/23-2Z wells.
A number of low relief anticlinal closures have been mapped, some of which may form extensions of the Old Head accumulation.
A NE -SW trending faulted anticline that may form a separate structure has been labelled the East Kinsale Prospect and this shows evidence of gas escape on seismic.

Standard Exploration Licence 5/07 – “Rosscarbery”

Licence 5/07 incorporates part-blocks 48/17, 48/18 and 48/19 adjacent to and immediately north-west of the Kinsale Head Gas field. The licence encompasses an area of 181 sq. kms, lies in water depth of circa 100 metres, and is currently held 99% by Lansdowne as operator. This licence contains the Galley Head gas discovery with potential for 30 BCF GIIP/ 25 BCF recoverable and the SE Rosscarbery and Rosscarbery Prospects with combined P50 prospective resources of 324 BCF GIIP/ 247 BCF recoverable .

The Galley Head discovery well (48/18-1), lying some 6km northeast of the main Rosscarbery Prospect, was drilled by BP in 1985 and tested gas at 13.7 mmscfd from the Lower Cretaceous Greensand, ‘A’ Sand, reservoir.
In post-well evaluation studies, BP identified a number of other structures, with the main prospect being what is now called Rosscarbery.

Standard Exploration Licence 5/08 – “Amergin”

Licence 5/08 incorporates part-blocks 47/25, 48/21 and 48/22 on the north-western flank of the North Celtic Sea Basin. Situated in water depths of c.100 metres, the blocks cover an area of 227 sq kms and are approximately 30km from the south coast of Ireland.

Two large structures, Amergin and Eremon, have been mapped at Jurassic level.
Mapped on 3D seismic, Amergin is a tilted fault block with dual primary reservoir objectives at Basal Wealden & Basal Upper & Middle Jurassic levels. The Basal Wealden sandstone is a proven reservoir with the Barryroe 48/24-10z appraisal to the south having tested oil at 3514 bopd in March 2012. The primary Jurassic reservoir target tested at a rate of 6,467 bopd in the Gulf Oil 49/9-2 discovery of the Helvick Field in 1983. Secondary reservoir targets may exist in deeper Jurassic (Sinemurian) sandstones and shallower Cretaceous (Wealden) sandstones.
Amergin has potential for 739 mmbbls STOIIP / 231 mmbbls recoverable.
Another feature, the Eremon structure is a northeast-southwest trending horst block mapped at Jurassic level, the only structure of this type identified on the northern flank of the basin.
Lansdowne acquired 489 kms of new 2D seismic data in May 2008 over both the Amergin and Eremon structures and 3D seismic over the Amergin structure in 2011.
This data has been processed and interpreted.The new 2011 3D seismic data has resulted in much better imaging of the Amergin structure and has confirmed the prospect as a robust structural closure ready for drilling.

Standard Exploration Licence 2/07 (49/9p) – “Helvick”

(lease undertaking application under consideration)
The Helvick field is situated some 40km offshore Ireland in c. 80m (265 ft) water depth. The field was discovered in 1983 by Gulf Oil with the drilling of the 49/9-2 discovery well. This well was tested and flowed at a cumulative rate of c. 10,000 BOPD from four zones. The Helvick oil is a light (44° API) and non-waxy crude oil, contained in high permeability Upper Jurassic sands.

Standard Exploration Licence 1/11 – “Barryroe”

Licence 1/11 (“Barryroe”) incorporates part blocks 48/22, 48/23, 48/24, 48/27, 48/28, 48/29, 48/30 covering an area of 614  sq km along the axis of the North Celtic Sea Basin. The Barryroe Licence is held by Lansdowne (20 per cent) and Providence Resources plc (80 per cent). Part of the Barryroe acreage lies beneath the Seven Heads Gas Field, with the boundary between the two concessions lying at 4,000ft (approximately 1,250m) sub-sea.

Lansdowne participated in the successful appraisal well 48/24-10z which tested 43 degree API oil at 3514 bopd. Three previous wells tested oil in the Barryroe Licence acreage which lies directly below the Kinsale Energy Limited operated Seven Heads Gas Field. The reservoir sands are in the Cretaceous Middle and Lower Wealden sequences between 1,400m and 2,300m (approximately 4,600 to 7,550ft) below sea level.

Two wells drilled by Esso in 1973/1974 tested oil. Well 48/24-1 from Middle Wealden sands at an aggregate rate of 1300 barrels per day and 48/28-1 tested oil from a Middle Wealden sand at 1527 barrels per day. A third well, 48/24-3 drilled by Marathon in 1990, tested oil from Lower Wealden sands at an aggregate rate of 1619 barrels per day.

Oil tested is a light 43 degree API, with a high wax content ranging c.17%
Lansdowne’s share of 2C recoverable resources in Barryroe is 69 MMBOE
Following integration of the successful appraisal well results the updated Oil In Place  P50 Resource estimate by the Operator for Barryroe is 1,043 mmbbls.
