OML 40 Located in the north western part of the Niger Delta 90 km north west of Warri; (swamp environment). Production licence with area of 498 km 2. Originally operated by SPDC (Shell), which drilled nine exploration wells between 1971 and 1991. All were drilled on 2D seismic and but one were vertical. Eight of the nine found oil. 371 km 2 of 3D seismic was acquired in 1990-91 (W) and 1995 (E). OML 40 was transferred to NPDC (55%, Operator) and Eland (Elcrest) (45%) in 2012. Benin City Contains one producing field (Opuama); one field being developed (Gbetiokun); five other discoveries and over twenty prospects and leads.

OML40 Ubima Geological Setting Slide: 7 Capital Markets Day
Geological Setting Benin Formation. Sand-dominated interval of late Miocene to Recent age, deposited in predominantly fluvial environment. No direct hydrocarbon potential but provides burial necessary to mature the Akata source rocks. Agbada Formation. Interbedded sandstones and shales of Eocene to Miocene age deposited in shallow marine / shoreface to channelised fluvial environment at depths of 4,500 to 10,000 feet. Provides reservoir and seal. Major NW-SE trending channels of late Miocene age (15 Ma) cut down into the Agbada Formation. Akata Formation. Thick, shale-dominated, low net to gross interval but with occasional thick sands deposited in deeper water, slope and basin floor environment. Contains numerous organic rich source intervals. Often overpressured. Slide: 8 Capital Markets Day

Ubima-1 EPS The Ubima-1 well is suspended. It found light oil in the relatively deep F7000 reservoir, oil in the intermediate depth E1000 and E2000 reservoirs and oil in the relatively shallow D1000 reservoirs. Major uncertainties: - STOIIP in D1000 reservoirs (ODT only - depth of OWCs not known). - Oil properties, especially the D1.0 reservoirs. Objectives: Appraise Ubima discovery (substantial upside, especially D1.0 reservoirs) Generate early cashflow (positive NPV). Slide: 40 Capital Markets Day
Ubima-1 EPS Eland will re-enter Ubima-1, drill out cement, and install dual completion, producing F7000 and E reservoirs on LS; D1000 reservoirs on SS. Production using minimum facilities, with export by truck. AGR-TRACS (April 2016 CPR) forecasts 2P initial rate of 2,500 bopd with ultimate recovery of 2.4 MMstb gross over 4 years. AGR-TRACS has contingent resources (2C) of 31.2 MMstb gross from full field development (four horizontal wells draining D1000 and E reservoirs). Development could act as regional hub.

Gbetiokun Full Field Development Base Case static and dynamic models have been used to optimise the number, location and sequencing of wells required to develop the field Objectives: - Maximise production and recovery by draining the main reservoirs early in the sequence - Gather key appraisal information in advance of subsequent wells Production profiles (oil, water and gas) have been generated and indicative well trajectories and drilling schedule prepared. About twelve new wells (in addition to Gbetiokun-1) are potentially required to fully develop the field, maximising recovery The majority of the wells are dual completion, with additional reservoirs accessed via sliding sleeves as the reservoirs developed initially are depleted. The exceptions are wells I, J and K, which are assumed to be single completion, draining the D5.0 reservoir The twelve wells provide a total of 29 reservoir drainage points over the life of the field Slide: 50 Capital Markets Day

Gbetiokun Full Field Development: Initial wells The first six new wells drain the D9.0 and deeper reservoirs and appraise the shallower D5.0 and D7.3 reservoirs, providing information on oil properties These six wells are forecast to produce at high rates and to provide high incremental reserves per well Total recovery from Gbetiokun-1 and the first six new wells is provisionally estimated by Eland to be about 65 MMstb by 2030. (This assumes gas lift is available for the E2.0 and shallower reservoirs. Without it, the recoverable volume from Gbetiokun-1 and the first six wells falls by 4 to 5 MMstb i.e., to about 60 MMstb.) Slide: 54 Capital Markets Day
The first six wells focus on the deeper reservoirs Slide: 55 Capital Markets Day
Gbetiokun Full Field Development: later wells The second six wells drain the D5.0 and D7.3 reservoirs. These reservoirs are significantly shallower than the D9.0 and E reservoirs and their oil properties are not known There is some evidence that the D5.0 and D7.3 accumulations may be compartmentalised, structurally and / or stratigraphically. The first six wells will provide information on D5.0 and D7.3 oil properties. However, they are not expected to markedly reduce uncertainty on D5.0 and D7.3 with respect to compartmentilisation, as the D9.0 and D5.0 structural culminations are offset from one another Slide: 56 Capital Markets Day
The second six wells focus on the shallower reservoirs Slide: 57 Capital Markets Day
Gbetiokun Full Field Development Total recovery from the second six wells is provisionally estimated to be about 14 MMstb * i.e., incremental recovery of 2 to 3 MMstb per well, significantly lower than for the first six wells. However, the D5.0 and D7.3 wells are still expected to have attractive economics Preliminary modelling indicates recovery from the second six wells is increased (i.e., above 14 MMstb) if wells I, J and K are complete as dual completion wells, producing the upper and lower D5.0 sands separately Oil production is forecast to peak at over 50,000 bopd and gas production at 25 MMscfpd * Facilities design and cost estimation work is being carried out by Genesis * Company estimates Slide: 58 Capital Markets Day
