Wood Mackenzie: East Africa’s Yet-to-Find Reserves Hold 95 tcf of Gas

Wood Mackenzie: East Africa’s Yet-to-Find Reserves Hold 95 tcf of Gas| Offshore Energy Today

Wood Mackenzie estimates that 100 trillion cubic feet (tcf) of gas has been discovered in Mozambique and Tanzania to date, ranking the Rovuma Basin as one of the most prolific conventional gas plays in the world.

However, there are significant technical and commercial challenges to be overcome in order to bring the gas to market by the end of this decade. These include: addressing issues around infrastructure, government capacity, financing and reaching a positive outcome to unitisation negotiations in Mozambique.

Recent discoveries and high profile M&A activity in Mozambique and Tanzania are attracting attention and Martin Kelly, Wood Mackenzie’s Head of Sub-Sahara Upstream Research, says the interest is justified: “100 tcf of gas has been discovered to date in East Africa and we estimate yet-to-find reserves could be as much as 80 tcf in Mozambique and 15 tcf in Tanzania. There is clearly plenty of gas to supply the likely commercialisation route of LNG – theoretically enough to support up to 16 LNG trains.

“The Rovuma basin is the most prolific in the region, and one of the hottest conventional gas plays in the world, with 85 tcf discovered so far. Globally in 2011, it yielded the third most hydrocarbons, and we expect it to top the list in 2012 if the first half of the year is anything to go by,” Kelly continues.

In neighbouring Tanzania, the targets are the northern extension of the Rovuma Basin and the Mafia Basin. Kelly says: “Tanzania has enjoyed considerable exploration success as well, but hasn’t discovered the same scale of reserves. The average discovery size is much smaller at around 2 tcf, compared to Mozambique which is over 7 tcf. Discoveries in Tanzania are also more spread out, so developing them will be more expensive than those in Mozambique because additional infrastructure will be required.”

One of the most immediate challenges for Mozambique, is the unitisation discussions which Wood Mackenzie understands have already begun. Kelly explains; “Of the 85 tcf of gas discovered to date in Mozambique, around half of it is thought to be one enormous field which is in communication across the block. Under Mozambican law, a unitisation agreement between the operating parties will be required.”

Although there is a risk that unitisation discussions could delay Final Investment Decision (FID) – the crucial last step before commercial development – and therefore LNG production, there are other discoveries which are wholly contained in Area 1 and Area 4 and therefore gas could come from these first.

Giles Farrer, Senior LNG research analyst for Wood Mackenzie comments: “Many challenges will need to be overcome prior to LNG project sanction. The region’s remoteness and lack of development present serious technical obstacles. There is virtually no existing skilled workforce and both Mozambique and Tanzania will have to build and establish deepwater ports capable of servicing the needs of the petroleum sector. On the commercial side, there is the question of government capacity – whether there is sufficient impetus and capability within the governments and national oil companies to advance the huge legislative, bureaucratic, customs and financial challenges that such a development would bring.

“The major outstanding milestone for Mozambique is the conclusion of a commercial framework agreement, which is in the process of being negotiated. It will determine how the LNG facility or facilities will be structured for the purpose of taxation and whether the Joint Ventures (JVs) will co-operate in the construction of a single, mega LNG facility, or pursue individual developments. One crucial advantage that the Tanzanian projects enjoy is that they have already negotiated commercial terms, prior to the announcement of their projects.”

Farrer continues: “Lastly there is the question of finance, we estimate that a two train greenfield development in the region is going to cost at least US$25 billion, and for some of the players involved financing their share of this sort of development cost will certainly prove challenging and could delay development.”

The joint analysis by Wood Mackenzie’s upstream and LNG research teams stresses that these challenges are not insurmountable. “They have been encountered and overcome in several countries before. The risk is that delays could lengthen development schedules and add to costs,” Farrer says in closing.

5th Discovery in a Row for BG Group Offshore Tanzania

https://i2.wp.com/d3n6f555sx1wcx.cloudfront.net/wp-content/uploads/2012/05/Five-in-a-Row-for-BG-Group-Offshore-Tanzania.jpg

BG Group today announced its fifth consecutive Tanzania gas discovery with the Mzia-1 exploration well located in Block 1, offshore southern Tanzania.

Mzia-1 is BG Group’s first discovery within the deeper Cretaceous section and opens an extensive new play fairway within the Group’s offshore acreage in Blocks 1, 3 and 4, to complement the now proven Tertiary fairway.

Preliminary evaluation of the results indicates 55 metres of natural gas pay in good quality sands. An extensive logging programme has been completed, including the acquisition of pressure data and gas samples.

Significantly, the well has de-risked a number of adjacent Cretaceous prospects, which could form part of a future Mzia hub. These prospects are expected to be tested in a future appraisal programme to be defined following incorporation of data from this new well and 3D seismic.

The new resources proven by Mzia and the potential of adjacent prospects are currently under evaluation. Prior to drilling Mzia-1, BG Group had estimated mean total gross recoverable resources approaching 7 trillion cubic feet of gas from the four previous discoveries drilled in Tanzania.

Mzia-1 is approximately 45 kilometres offshore southern Tanzania in a water depth of 1 639 metres. It is some 23 kilometres from the Jodari-1 discovery and is part of the 2012 three-to-four well exploration programme.

Following the imminent completion of operations at Mzia, the Deepsea Metro-1 will relocate to Block 3 for the drilling of the next exploration prospect, Papa-1.

BG Group as operator has a 60% interest in Blocks 1, 3 and 4 offshore Tanzania, with Ophir Energy plc holding 40%.

Eni Scores Again in Area 4 Offshore Mozambique
Mar 26, 2012 – Eni has made a “giant” natural gas discovery in Area 4 offshore Mozamique at the Mamba North East 1 exploration prospect. The operator said that the results of this well are of special importance since they increase the resource base of Area 4 by at least 10 Tcf of which 8 Tcf of these contained in reservoirs exclusively located in Area 4. This new discovery further improves the potential of the Mamba complex in Area 4 offshore Mozambique, now estimated to hold at least 40 Tcf of gas-in-place. Mamba North East 1 encountered a total of 787 feet (240 meters) of gas pay in multiple high-quality Oligocene and Eocene sands. It proved reservoir continuity and pressure communication with Mamba South 1 and Mamba North 1 wells. During 2012, Eni plans to drill at least another four wells in nearby structures to fully assess the upside potential of the Mamba Complex.

Total Believes Gas Coming from Rocks above Elgin Reservoir
Mar 29, 2012 – Total may have confirmed the source of the gas leak at its Elgin platform in the Norwegian sector of the North Sea. The firm insists that the still-alight flare on the platform does not pose any immediate risk. After reports early Thursday morning that Total had a “good idea” of the source of the gas leak on its Elgin platform, a spokesperson for the firm told Rigzone: “We believe the hydrocarbons are coming from a rock formation above the reservoir at a depth of 4,000 meters [13,120 feet].” On Wednesday evening, Total released a press statement explaining the situation regarding the flare on the Elgin platform. “The flare is an integral part of the platform’s safety system. In an emergency, it is used to safely evacuate all the gas from the platform. During the incident, it performed this task perfectly, allowing everyone to evacuate safely,” said Total. “The flare is still lit because when the platform is shut down and de-pressurised in an emergency, it cannot be fully purged as done in a controlled shutdown. This is perfectly normal. Some liquids do remain in the system and these liquids are now evaporating. As these liquids evaporate, the flow of hydrocarbons to the flare will exhaust itself and the flare should burn out.”

Lundin Completes, Tests Johan Sverdrup Appraisal Well
Mar 26, 2012 – Lundin Petroleum announced that the Johan Sverdup appraisal well 16/2-11 encountered a 177-foot (54-meter) gross oil column in Upper and Middle Jurassic sandstone reservoir in an oil-down-to situation. A comprehensive logging and coring program was successfully completed as well as a production test in the previously untested Middle Jurassic reservoir. The data from this first well in the 2012 PL501 appraisal program confirmed good reservoir properties. This is in line with the earlier Johan Sverdup wells where the Upper Jurassic reservoir was of excellent quality with a high net to gross ratio. A full scale production test (DST) in the Middle Jurassic reservoir to investigate its flow properties resulted in flow rates, in excess of 2,700 bopd through a restricted 40/64 choke, with good reservoir properties indicating a lateral continuous reservoir. Lundin will now sidetrack the well towards the east to investigate the lateral thickness and property variations of the Jurassic reservoir as well as establish an oil water contact to investigate the possibility of a deeper oil-water-contact in this area.

Statoil Hits Oil Pay Near Oseberg
Mar 23, 2012 – Statoil has made a small oil discovery in PL053 production license in the Norwegian sector of the North Sea. The consortium is in the process of concluding drilling operations in exploratory well 30/6-28S. The well, drilled by the COSLPioneer (mid-water semisub), proved an oil column of around 40 feet (12 meters) in the Statfjord formation. The estimated volume of the discovery is in the range of 12 to 18 MMbbl of recoverable oil equivalents. Statoil said the find is located beneath the Oseberg field and is a good candidate to be connected to the Oseberg production facilities. The oil discovery lies in the Crimp prospect, which was the secondary target for exploration well 30/6-28S. The primary target was the Crux prospect that Statoil earlier defined as a high-impact gas opportunity. With the Crux prospect Statoil tested a hypothesis for the existence of a separate gas-filled structure underlying the Oseberg field. However, the Crux prospect did not contain hydrocarbons.

Waimea, Waikiki to be Declared Commercial in 2012
Mar 23, 2012 – Dow Jones Newswires reported that OGX plans to declare the Waimea and Waikiki offshore oil fields commercial in 2012. The Waimea field, which came online in January, will be commercially declared in the second quarter; and Waikiki will also receive a similar declaration some time this year. The operator plans to submit a development plan for Waimea to Brazil’s National Petroleum Agency, or ANP, in the second quarter. Upon approval, additional wells will be connected to the OSX-1 FPSO. Waimea is currently producing about 12,500 bopd from a single production well, with output expected to reach 40,000 to 50,000 bopd by the end of 2012. Increased output is set to come from two additional production wells that will be connected this year, with engineering studies underway to gauge the feasibility of adding a fourth production well. Furthermore, OGX plans to bring Waikiki online in 2013. The operator stated two FPSOs, OSX-2 and OSX-3, are about 30 percent complete and construction is continuing at a Singapore shipyard.

McMoRan Updates Flow Testing Ops at Davy Jones Well
Mar 29, 2012 – McMoRan is continuing to flow test the Davy Jones No. 1 well on Block 230 at South Marsh Island. As previously reported, McMoRan saw positive pressure response from the Wilcox “D” sand which was perforated on March 24, 2012. On March 26, 2012, the operator attempted to perforate the Wilcox “C” sand. As the perforating gun was being removed from the hole, the well began to flow. When the gun was brought to the surface, it was determined that the gun did not fire in the Wilcox “C” sand from what appears to be a simple disconnection of the detonator cord. The company plans to use a new perforating gun to complete the testing of the Wilcox “C” sand. Currently, the test is ongoing from only the Wilcox “D” sand, which resulted in the flare shown in the exhibit attached. The flow from the “D” sand is being affected by considerable debris in the 5-inch liner, from what McMoRan believes to be residual drilling fluid from drilling of the well. Results of a clean flow test, as opposed to the current test hampered by debris, will be announced as further progress is achieved and flow rates are measurable. McMoRan will provide updates as completion operations progress.

by  BG Group
Press Release
Monday, March 26, 2012

BG Group announced Monday a fourth Tanzanian gas discovery from the Jodari-1 exploration well located in Block 1 offshore southern Tanzania. Preliminary evaluation of the well results indicates gross recoverable resources are in the range of 2.5 to 4.4 trillion cubic feet (tcf) of gas.

The partnership of BG Group (60 percent and operator) and Ophir Energy (40 percent) have had exploration successes in all four wells so far drilled in Tanzania, with mean total gross recoverable resources currently estimated to be approaching some 7 tcf of gas.

Jodari-1 is located approximately 24 miles (39 kilometers) offshore southern Tanzania and in a water depth of 3,770 feet (1,150 meters). It is part of the current three-to-four well exploration program, which also includes the acquisition of 965 square miles (2,500 square kilometers) of 3D seismic data in Block 1.

The next target for drilling is the Mzia-1 location in Block 1, some 14 miles (23 kilometers) to the north of Jodari-1. The discoveries announced previously are Chaza-1 in Block 1, and the Chewa-1 and Pweza-1 discoveries in Block 4.

image

Statoil and partner ExxonMobil confirmed that the Zafarani-1 well in Block 2 offshore Tanzania has encountered indications of natural gas in a good quality reservoir.

Drilling operations are still on-going and it is too early to give any indication of size and commerciality, Statoil said in a statement.

The well was spudded in early January 2012 and drilling operations are expected to take up to a total of 3 months to complete.

The well is being drilled by the drill ship Ocean Rig Poseidon and is located some 80 kilometers off mainland Tanzania.

It is the first exploration well that has been drilled in the license which covers an area of approximately 5,500 square kilometers. The water depth at the well location is 2,582 meters and the well itself is planned to reach a total depth of 5,150 meters.

Statoil operates the license on Block 2 on behalf of Tanzania Petroleum Development Corporation (TPDC) and has a 65% working interest with ExxonMobil Exploration and Production Tanzania Ltd. holding the remaining 35%.

Statoil has been in Tanzania since 2007 when it was awarded the license for Block 2.

TPDC is pleased about these preliminary results and is eagerly awaiting further information on this operation,” says Yona Killaghane, Managing Director of TPDC.

The final assessment of what has been encountered will be released at a later stage once drilling operations have been completed and the well results fully analyzed, Statoil said.

Ophir announces the start of its 2012 drilling programme in Tanzania with the drillship Odfjell Metro-1. The first three wells in the programme will be Jodari-1, Mzia-1 (previously named 1W) and Papa-1 (previously named 3A).

The Metro-1 is a state-of-the-art drillship capable of drilling in water depths of up to 3,000m. The rig has a dual derrick with a main work centre and an auxiliary work centre to facilitate a number of simultaneous operations. Both work  centres are equipped for drilling. The Metro-1 was built at the Hyundai Heavy Industries yard in Ulsan, South Korea and a detailed series of acceptance tests have been performed ahead of mobilisation to Tanzania.

The Jodari-1 and Mzia-1 wells are both located in Block 1. For efficiency reasons the Mzia-1 top hole section will be drilled first, as part of a batch drilling programme, then the rig will move to drill Jodari-1 in its entirety, before returning to Mzia-1 to complete the bottom portion of the well.

The Mzia-1 well spudded in 1,500m of water on 1 January 2012 and drilling of the top hole section is expected to take 7 to 10 days. Thereafter the Jodari-1 well will spud in a water depth of 1,155m and drill to total depth of c 4,600m subsea in an estimated 40 days. The Jodari prospect contains multiple stacked targets in both the Tertiary and Cretaceous sections with the former having seismic flat spot and amplitude fit to structure. Jodari is modelled by Ophir to contain mean resources of 2.2Tcf in the stacked targets.

Ophir holds 40% of Blocks 1, 3 and 4 and has now fully handed over operatorship to 60% partner BG International, who will manage the programme with the Metro-1.

Ophir CEO, Nick Cooper said: “2012 has the potential to be transformational for Ophir. We are pleased to start the year by kicking off our Tanzanian drilling programme and also to see drilling and seismic operations gearing up across our other key assets. Ophir plans to drill at least 9 wells across our portfolio in 2012.”
