27 Geology

28 The Niger Delta

 OML 30 lies within the Niger Delta, located in the Gulf of Guinea, one of the most prolific oil and gas provinces in the world  From the Eocene to the present, the delta has prograded south- westward, forming depobelts that represent the most active portion of the delta at each stage of its development  These depobelts form one of the largest regressive deltas in the world covering approximately 75,000 square kilometres with a source rock thickness of up to 7,000 metres

29 The Niger Delta cont’d

 OML 30 fields are deltaic shallow marine shelf sands (usually shore face sands) at intermediate depth level in growth fault structural setting  Traps are typically related to rollover structures or anticlines of simple fault complexity  Progradation in the face of significant wave reworking has created sheet-like layers of shoreface sand with excellent reservoir quality  The wave action has created reservoirs with porosities of 20-30%  Permeability is typically greater than 500 mD and up to 3,000 mD

30 Reservoir Structure and Traps

 The structural configuration in the Niger Delta can generally be characterized as simple rollover structures  The structure is associated with landward dips that are associated with structure building faults located in the northernmost fault blocks of the basin  Structures tend to be bounded down dip by another structure- building fault  OML 30 reservoirs are typically anticlines structures. Some are bound to the north east by faults

31 Stacked Reservoirs

 The progradation of the Delta coupled with the sea level changes controlled depositional patterns and caused facies changes that have resulted in stacked reservoirs  Sands with thickness of 10 to 40 metres were sandwiched between shales that created sealing caps above reservoirs  The OML 30 fields each contain up to 40 stacked reservoirs. The seismic section for the Afiesere field shown at left contains twenty one such layers, or stacked reservoirs. The chart illustrates the reserves associated with those reservoirs  An alphanumeric system , that is unique to that field, is used to label the reservoirs. The top reservoir in Afiesere is the J1000 while the deepest reservoir is the M8200  Each layer exhibits different reservoir and hydrocarbon characteristics  Reservoirs contain different types of hydrocarbons ranging from under-saturated oil to gas-condensate  OML 30 reservoirs are typically normally or slightly over-pressured  The reservoirs are underlain by substantial aquifers that provide nearly infinite pressure support

34 Infrastructure

35 Infrastructure Overview

 The licence benefits from all infrastructure being in place  The licence includes 190 production wells, most are dual string. Injection wells and water injection facilities are unnecessary due to the strong aquifers  Well production is collected at one of nine flow stations. The flow stations have the capacity to handle 395,000 bpd, three times current production levels and will handle several years of projected production growth  The facilities are robustly designed and constructed and benefit from following a standard design so equipment can be easily replaced  The facilities have been maintained by Shell and therefore benefit from their worldwide experience and standards  Licence includes ownership of the Trans Forcados Pipeline that transports crude 95 kilometres to the Forcados Terminal

36 Field Flow Stations

 Production for the wells is gathered at field specific flow stations  The flow stations separate liquid from gas through a simple two stage separation process  Liquids are then pumped via a trunk line collection system to a central manifold at Eriemu and onward through the Trans Forcados Pipeline  Gas is used as fuel for power generation, run the compressors and as gas lift gas. Any remaining gas is flared  Design of the flow stations follows a similar template, and vessels are similarly sized, making operations and maintenance straightforward  Capacity of the stations is listed at left. Total capacity is c. 395,000 bpd. Current throughput is c. 120,000 bpd so there is substantial existing capacity to accommodate future production. The expansion of the facilities is straightforward and has been documented in various FDP’s

37 Gas Lift Compressors

 Gas lift is the single method of artificial lift within OML 30  Six of the eight fields have gas lift installed. The two remaining fields are planned to have gas lift installed in 2014-2015  Poor compressor performance and high downtime are the cause of inefficient lifting and significant shortfall in daily production  Improving the performance of the gas lift system is projected to increase production by 20% and is the key target in 2013

38 Ughelli Pumping Station

 The Ughelli Pumping Station, (“UPS”) is the collection hub for OML 30 and several other operators’ production  The facility has storage for 960,000 bpd of liquid and pumps the liquid from the tanks down the Trans Forcados Pipeline to the Forcados Crude Terminal  Three Solar turbine powered pumps having a total capacity of 660,000 bpd perform the pumping  The current facility is used to dewater crude for the Warri refinery. Crude is separated from water via gravity separation and pumped from the tank via a dedicated pipeline to the refinery

 The 960,000 bbl of storage also provides several days of storage in the event of a shipping disruption on the Trans Forcados Pipeline  Future plans call for expansion of the water separation capacity by adding permanent subsurface water disposal facilities including conversion of a suspended well to an injector into the substantial aquifer and providing a water disposal line and injection pumping

39 Gas Export

 Gas export, surplus to internal requirements for gas lift and fuel, is available for export via the Nigerian Gas Company (“NGC”) facilities  The NGC facilities include gas compressors and trunk lines for conserving gas. Total capacity is 42 MMscf/d  Gas is collected from the six largest OML 30 fields (Kokori, Afiesere, Eriemu, Oweh, Olomor Oleh and Uzere West) and transported to the nearby Ughelli gas plant where it enters the Nigerian domestic distribution system  At present, the system is non operational awaiting NGC to repair the gas gathering pipelines  OML 30 has a “domestic supply obligation” of 40 MMscf/d. In the event domestic demand requires it, the licence is expected to supply gas to the domestic and power generation markets of up to 40 MMscf/d. As gas supply far outweighs domestic demand, it is unlikely this obligation will be called on. In the event the supply is required, OML 30 can quickly recomplete an existing well on a gas reservoir and meet this commitment  2.5 TCF of gas in the licence not included in the RPS report NGC Sales Capacity

40 Trans Forcados Pipeline

 The TFP is owned by OML 30 (45% owned by Shoreline)

 This satellite photo illustrates the route of the Trans Forcados Pipeline; stretching from the Eriemu manifold in the east, through the UPS, around the Rapele north of Warri and westwards through MF OML’s 34 and 42 to the Frocados UPS terminal, located within OML 45, where Eriemu the crude is dewatered Field MF  The TFP stretches some 95 km starting Forcados as a 16" pipeline at the Eriemu manifold River MF in OML 30 increasing to 24” on exit from the UPS and increasing to 28” at the Rapele manifold

Forcados  Along the pipeline there are several Terminal intermediate tie-in manifolds

 Pipeline is buried

41 Trans Forcados Pipeline

 OML 30 owns and operates the TFP

 Several other operators currently use the TFP to transport crude to Forcados for dewatering and export. Capacity of the line is 850k bpd. Current use is c. 315kbpd

 These operators pay OML 30 a ‘Capacity tariff’ ranging from $0.11 to $0.87/bbl and a ‘Production charge’ of $0.17 to $0.44/bbl. The tariffs are based largely on the length of the line that is used

 OML 30 does not pay a tariff

 TFP projected tariff revenues total $57.4m. The 2012 actual Opex was $4.4m. Advice received from PWC is that the pipeline revenues will be taxed at a corporate income tax rate of 30%

44 Realising Existing Potential and Future Upside

 Increase production through: Short term  Improved gas lift by refurbishing existing system

 Complete repairs to flow and gas lines and tie-in wells

 Prevent downtime through improved community relations and share in profits to reduce vandalism

 Invest in facilities to increase uptime

 Modernise facility control equipment to increase efficiency

Medium  Workover existing shut-in wells to improve completions and to install gas lift in wells without term artificial lift

 Large stock of proved drilling locations determined from 3D seismic

 Upside potential through focused management of the field and employing techniques such as multiple completions and horizontal drilling Long term  Future exploration of deeper targets identified on 3D seismic  Future gas prices may lead to developing gas reserves

 Lease extension past 2019; expected to be renewed thereafter as legislation provides for extension

46 The Work Programme – Gas Lift

 Gas lift is the key short term focus  Compressors are operating below design capacity and require refurbishment (pistons, valves, gaskets, etc)  Current compressor uptime c. 65%. Target to increase to 95%. Resulting production gains c.10,000 bopd. Downtime caused by engines tripping due to mechanical integrity issues and fuel gas supply pressure. Study currently underway by the compressor manufacturer  Subsurface gas lift operation is inefficient  Valves not set at correct depths and not working as designed. Results in inefficient lifting and waste of gas lift gas  Detailed data gathering and well by well review underway with Government. Target is to optimise lift on 32 strings with associated production gains target of c.8,100 bopd  Gas lift not installed to all wells  As water cut increases gas lift is required to maintain production. At 70% watercut wells will stop flowing. Gas lift system to be expanded in fields that currently have compressors. Target is to install gas lift to 19 wells in 2013 and 2014. Resulting production gains c.4,300 bopd  Gas lift systems to be installed at Oroni and Evwreni fields (these two fields currently have flowing wells only). Production gains associated with installing gaslift in Oroni and Evwreni total 3,600 bopd Gas Lift Optimisation and Expansion 25 Uzere West

47 The Work Programme – Flowline Repairs

 Some wells have damaged or vandalised flowlines that require repairs

 Flow lines are often ‘hack-sawed’ by locals to bunker small amounts of fuel or as vandalism

 Plan is to ensure every well string has a functioning flow line

 Twenty three wells do not have flow lines. Well surveillance and historical information indicates these wells are productive on the current completion but also could be recompleted on shallower reservoirs

 Target production increase associated with flowlines is 6,300 bopd

48 The Work Programme – Workovers

 The licence includes 190 wells. Among those, 70 wells are currently temporarily suspended for various issues. Among the 120 that are available to be produced, half are operating sub-optimally

 Workovers are planned on wells to optimize gas lift design. Valves have been installed at the wrong depth and in many cases valves are not working. If the work cannot be completed using wireline equipment, a workover will be completed

 The reservoirs are comprised of slightly unconsolidated sands and have typically been completed with gravel packs. Some wells are shut- in requiring workovers due to high sand production and require replacement of the gravel packs or installation of other sand control measures

 Advancing aquifers cause increasing water production. Several opportunities to increase production by completing water-shut-offs. As deeper reservoirs become depleted wells can be recompleted on shallower reservoirs

 So far 41 workovers have been identified with target gains totaling 9,600 bopd

49 The Work Programme – Drilling Proved Locations

 Of the current c.190 wells only 30 wells were drilled post the initial field development period that occurred between 1960 and 1980

 The lack of continued development has resulted in an extensive catalogue of proved drilling locations, currently totaling c. 220

 Potential well locations have been extensively studied and well documented in past FDP’s

 Plan is to verify the technical work within the existing FDP and use these as guidelines for near term development

 The existing FDP’s call for extensive development using horizontal drilling technology to reduce gas and water coning and to maximise recovery factors. Horizontal drilling is being used extensively in the region

 Horizontal drilling is proven in the delta

 Infill drilling is scheduled to commence in 2014. Tendering for the first drill rig is moving in parallel with a rig for an adjacent licence
