WINDHOEK, August 9th, 2016, Nabirm. (” the Company”) is pleased to announce that, as a result of meeting and exceeding its exploration work obligations, it has requested and received approval from the Namibia Ministry of Mines and Energy (“Ministry”) relating to Block 2113A (PEL 0058) onshore and offshore Namibia.
Block 2113A (PEL_0058)
In further recognition of the advancement of the exploration progress made on Block 2113A, including over 684 line kilometers of 2D survey, the Ministry has waived the relinquishment requirement (as stipulated in the Petroleum Agreement), and the Block partners will continue the exploration work on the entire block area.
Nabirm CEO, Olayinka Arowolo : “We are extremely pleased with the Ministry’s positive decision to support our progression into the next exploration phase on block 2113A onshore/offshore Namibia. Despite the market forces that have an adverse effect on the upstream sector, our continued financial and operational commitment to Namibia’s petroleum industry, has been recognized by the Government, hence the approval to enter the next exploration phase. Together with our partners NAMCOR, we are in a stronger position to continue to the next phase of exploration which is the acquisition of 3D seismic.
We have also noted that Tullow Kudu Ltd. (a wholly owned subsidiary of Tullow Oil Plc.) has decided to enter into drilling phase on its joint venture block License number 037 together with Pan Continental Oil and Gas NL (Tullow: 65%, Pan Continental: 35%). Block (PEL)037 is just west of Nabirm’s Block (PEL ) 0058, in the Walvis Basin. According to the license terms, the drilling should occur by March 2017.”
2D Seismic, Gravity and Magnetics Program Interpretation, Block 2113A offshore Namibia.
November 10, 2015 – WINDHOEK.
NABIRM the Atlantic margins focused oil and gas exploration company, today announces that in conjunction with its partner NAMCOR (10%) that it has concluded the interpretation of a 2D Seismic Survey (the “Survey”) on Block 2113A (the “Block”) located in the Walvis Basin, offshore Namibia, by U.S based ION Geophysics. The license block covers 5,750 km2, with 3,600 km2 located offshore and 2,150 km2 located onshore.
BGP International using the vessel M/V BGP Pioneer acquired the survey; earlier in 2015 the same vessel completed the Ion Geophysical NamibiaSPAN 2D survey in offshore. The M/V BGP Pioneer acquired 684 line kilometers of 2D seismic data plus ship borne gravity and magnetic data within Block 2113A. The survey was acquired with a single 9-kilometer cable towed 8 meters below the sea surface. Acquisition was completed on 20 March 2015. Parallel Geoscience processed the 2D seismic data in April and May of 2015. Ion Geophysical was contracted to perform the 2D seismic interpretation and received/loaded the processed 2D dataset into SMT/Kingdom on 6 July 2015, the final reports were published on the 4th of November 2015.
The objective of the seismic interpretation was to identify key depositional features (reflection types, continuity, terminations, downlap, toplap, onlap), structural features (highs, lows, faults and fault styles including normal, reverse, strike-slip) and anomalous reflection packages. The most significant surface within the dataset is a strong reflector at the top of a thick succession of low frequency reflectors. Utilizing the NamibiaSPAN 2D data, these horizons were correlated into Block 2113A. In addition to these regional horizons, local surfaces were identified from the PEL 58 2D Seismic Survey exploration grid and are described as Surface 1, Surface 2, Surface 3 and Basement. Time structure maps, depth structure maps, isochrons and isopachs have been generated for these key horizons.
Further, ION mapped six leads with total Pmean unrisked recoverable resources of over 520 MMBO. Stratigraphic lead designated ‘Ondo’ is the largest and of principal interest, with a Pmean of around 230 MMBO – ‘Ekiti’ is slightly smaller and exceeds 200 MMBO.
Olayinka Arowolo, Chief Executive Officer of Nabirm, the Operator of the Block commented: “ ION’s interpretation of Nabirm’s data; the established oil kitchen in the Walvis Basin confirming light 40 API degrees gravity oil; the oil shows onshore on Eco Atlantic’s Daniel Block which prompted the drilling of the Toscanini Well; and the slicks evident in the region from the Fugro Oil Slick study that was completed for Eco Atlantic, all indicate that Exploration in blocks adjacent to PEL 58 identify an oil mature fairway. Hydrocarbons generated within this fairway would be migrating eastward and updip toward Block 2113A. In onshore blocks, exploration is focused on Karoo age sediments. There is a high likelihood of Karoo sediments in Block 2113A. The Lower Cretaceous Twyfelfontein Sandstone has been mapped extensively onshore and likely extends into the offshore area. The Twyfelfontein Formation – Verbrande/Tsarabis/Huab Formations would be key reservoir-source rock components of a viable Petroleum System within Block 2113A. We still have significant work to do and further study is required, with shallow water depths and shallow drilling depths, we are intrigued by this very interesting Block.”

Proposed 2D Seismic Survey in License Block 2113a, Walvis Basin, off the Coast of Namibia
8 January, 2015 – WINDHOEK.
NABIRM Energy Services is set to undertake a 2D seismic survey in the offshore portion of License Block 2113A, Walvis Basin, Namibia. The purpose of this survey is to investigate the subsea geology of the licensed block for the presence of oil and gas. The proposed area of the 2D seismic survey will be approximately 1,050 km in length, comprising of low density spaced survey lines spanning an area of approximately 2,500 km2. Water in the proposed survey area ranges between 50m and 150m in depth, and the distance from shore ranges between 10 and 50km. CCA Environmental (Pty) Ltd (” CCA “) has been appointed to examine the baseline environmental conditions of the licensed survey area in order to evaluate the potential impacts of the proposed seismic survey and present the findings in an Environmental Impact Assessment (EIA). The technology being used will ensure that the integrity of the environment in and around the oil block will not have a negative impact on the environment, the wildlife ecosystem, on tourism in the area. The BID has been circulated for a two-week registration and comment period beginning January 7, and ending January 21, 2015.
Nabirm Announces Award of PEL 0058
13th July 2012 – WINDHOEK.
NABIRM announced that the company has been awarded a petroleum exploration license (#0058) for Block 2113A in Namibia. In July 2011, the Namibian Ministry of Mines & Energy announced an estimated 11 billion barrels in oil reserves were found off Namibia’s coast, with the first production planned within four years. The finding could put Namibia on par with neighboring Angola, whose reserves are estimated at around 13 billion barrels and whose production rivals Africa’s top producer Nigeria. According to Isaak Katali, Namibia’s Minister of Mines and Energy, HRT Oil & Gas Ltd, a Brazilian company working in the region, has raised $1.3 billion on the Brazilian stock market, with $300 million earmarked for oil and gas exploration in Namibia. Katali said that HRT has certified about 5.2 billion barrels of potential reserves in Namibia. “This finding could turn offshore Namibia into a great producer of oil and gas in a short time”, Katali said.
Olayinka Arowolo, CEO of Nabirm, commented : “Namibia has long been seen as a potential new source of oil, hampered by a lack of exploration to determine the extent of its reserves”, said Arowolo. “Its offshore geology is similar to Brazil, which is experiencing a boom in oil exploration and production. The issuance of this license in partnership with the National Petroleum Corporation of Namibia (NAMCOR) demonstrates that NABIRM is a preferred ‘partner-in-progress’ with NAMCOR as Namibia continues its exciting nation-building initiatives in the oil and gas sector”.
Nabirm Pleased with Prospects for Oil Block 2113A in the Walvis Basin
July 22, 2013, – WINDHOEK.
HRT’s Drilling Results
Nabirm notes the July 19, 2013 announcement from HRT Participações em Petróleo S.A. (“HRT”) regarding the results of the Murombe-1 well, which has reconfirmed the presence of an Aptian marine source in the Walvis Basin despite failing to find the presence of quality reservoir in the primary Murombe objective. Murombe-1 is the second well of a three well exploration programs being executed by HRT offshore Namibia. Murombe-1 is located in Petroleum Exploration Licence 23 in the south of the Walvis Basin, some 200 km south of Tower Resources plc’s multi-billion barrel Welwitschia-1 prospect, which is to be drilled in mid-February 2014 in PEL0010 by its operator, Repsol. HRT announced that the Murombe-1 exploration well was drilled to a total depth (TD) of 5,729 metres with the objective of penetrating two target reservoirs. The primary target was the Murombe reservoir, a Barremian age turbidite fan system, which from wireline logging confirmed a lack of reservoir quality facies and low porosity. However, a mature Aptian marine source in the “oil window” was encountered above the primary Murombe target confirming the source previously encountered in the Wingat-1 well announced on 20 May 2013. A secondary target, the Baobab reservoir, a shallower Santonian age, channel complex, encountered a 242 metre gross section with a net-to-gross ratio of 15% and porosity of 19%, however this was found to be water-wet. As a result the Murombe-1 well is being prepared to be plugged and abandoned.
Confirmation of Oil Presence in the Walvis Basin
As observed by both Nabirm and Tower Resources plc today, the presence of oil in the Walvis Basin has been confirmed. The main risk attributed to the primary Murombe basin floor fan target was reservoir quality. Importantly, the confirmation of an Aptian marine source, also encountered in the earlier Wingat-1 well, bodes well for Nabirm since the Aptian source would be mature and in close vicinity to the Block 2113A prospect. The result of the Murombe-1 well, although disappointing news for HRT, offers further evidence of a working source in the Walvis Basin. The question remains, to where has the oil from these source rocks migrated?.
Block 2113A’s Favorable Geology
All of the available geotechnical, geothermal and geochemical data suggests that this oil has migrated in the direction of Nabirm’s Block 2113A. Additionally, the significance of the following exploration drilling results within the Walvis Basin supports this favorable assessment and the prospectivity of Block 2113A:
- Tapir South-1: Drilled by Chariot Oil & Gas plc on Block-1811A between March and May 2012 and encountered over 200 metres of high quality reservoir in the Cretaceous and Carbonate sequences.
- Potential for oil versus gas: The probability of encountering light oil relative to gas within Tower’s Welwitschia prospect has increased from 50% to 65% and in the Alpha, Gamma and other inter-structural prospects has increased from 45% to 65%. This assessment is primarily driven by the discovery of light oil in the Wingat-1 well and the presence of abundant source rock.
- Geological chance of success (“GCos”): The GCoS remains unchanged as the improved probability of source rock inferred from the Wingat-1 well result is confirmation of the potential for oil generation.
Nabirm believes that the company’s shareholders are exposed to one of the highest impact exploration wells scheduled for 2014 in sub-Saharan Africa. Nabirm’s Block 2113A, held under PEL 0058, is located in a sedimentary system that has been deposited by the ephemeral river ‘delta’ system, which combines major feed from the Omaruru River and Uniab, Koigab, Springbok, Huab and Ugab ephemeral rivers, and benefits from offshore sedimentary feed. Block 2113A has geological structures with potential basin margins up-dip migration active petroleum systems. Structural influences of both the Walvis (Offshore) and Huab (Onshore) Basins, reveal the possible accumulation of potential hydrocarbon source sediments in both Basins over millions of years. Influences of the various tectonic phases resulting in potential up-dip migration pathways couple with basins margins structural traps all are key to unlocking of hydrocarbon sources and reservoir potential held in Block 2113A. Given all of these positive factors, Nabirm is pleased with its prospects for Block 2113A, and believes that the company is positioned for a successful outcome with this asset.
Recent Events in the Walvis Basin
September 13, 2013, – WINDHOEK.
Nabirm Energy Services (Pty) Ltd, a privately owned Namibian energy EPL company, is pleased with the prospects for its flagship oil asset – Oil Block 2113A – in the Walvis Basin. Recent events, including the Tullow’s farm in announcement for PEL 0037 in the Walvis basin in adjacent acreages, 2012B, 2112A & 2113B all held under PEL 0037 in the Walvis Basin favor a successful outcome for Nabirm’s Block 2113A held under PEL 0057.
Tullow is a highly successful oil explorer that has opened four new oil basins in Africa and South America in the last seven years. Founded in 1985, Tullow is now Africa’s leading independent oil company, and one of the largest independent oil and gas companies in Europe. Amongst Tullow’s key achievements is the 2007 discovery and subsequent development of the Jubilee Oil Field offshore Ghana. In the East African Rift Basins, Tullow’s successes include major oil discoveries in Uganda and recent significant oil discoveries in the South Lokichar Basin in Kenya. To date, in Uganda, Tullow estimates gross recoverable resources of 1.7 billion barrels of oil. Tullow farmed-in to Pancontinental’s interest in licence L8 offshore Kenya in 2011 and participated in the Mbawa 1 gas discovery in 2012. The joint venture continues to explore for oil in the L8 area. Tullow is developing the Kudu Gas Field offshore southern Namibia and farmed-in to Pancontinental’s EL 0037 licence in Namibia in September 2013.
Independent Resource Estimate Overview
DeGolyer and MacNaughton (“D&M”) has prepared an assessment of licence area EL 0037 offshore Namibia in accordance with the Petroleum Resources Management System (PRMS) approved by the Society of Petroleum Engineers, the World Petroleum Council, the American Association of Petroleum Geologists, and the Society of Petroleum Evaluation Engineers. D&M’s resource estimates recognize large stratigraphic leads in potential clastic turbidite targets. These targets appear to be in the oil window. These potential accumulations are categorized as “leads” based on the available seismic and geologic data. The potential accumulations are not yet classified as “prospects” that are available for drilling. D&M’s Mean Estimate for the total 11 Leads is 8.7 Billion Barrels of Gross Prospective (recoverable) Oil Resources.
We believe that the geochemical work done by HRT in the WALVIS basin was correct in identifying a deep source rock at or below the deep barramian, however, because the south Atlantic separated first in the south , there were widespread volcanics at that time in the south but not north of the walvis basin and hence there are different maturities for the source rocks for the deep barramian source rocks. Hence no oil in the main barramian prospect. However, we now know that there was oil in the aptian source rock which lies above the barramian target reservoirs and which make it difficult to charge lower reservoirs. Chariots acreage in block 2714 b and the central blocks in Namibia are focused on oil prospects charged by the aptian source rocks which migrate into huge turbidite sandstone reservoirs of the later cretaceous, just like what occurs in much of west Africa, and that’s why Tullow farmed into the Pancontinental blocks at a value of $200 million for PEL 0037.
Pancontinental has mapped an “Oil Mature Fairway” through EL 0037 and the Wingat area. Critically, using existing seismic data, good reservoir rocks are interpreted in channels and turbidites within and close to the Oil Mature Fairway in EL 0037 and some of these will be covered by the new 3D seismic survey. This demonstrates that a multidisciplinary approach to oil exploration, that takes all factors into account is required for explorers in the Walvis Basin. We are excited about Tullow’s prospects in the WALVIS basin given the fact that the largest acreage, block 2113B held under PEL 0037 is right next to NABIRM’s acreage 2113A.
