Maria, you've gotta see her!

Wintershall has shut-in the Maria field since February, approximately a year after first production, following poor production performance. It is understood that reserves have been downgraded from 207mmbbl to c.60 mmbbl.

The field is now undergoing testing and monitoring to see how best to produce the remaining reserves the recover the lost reserves whilst managing the reservoir. It is understood that the NPD has to review plans and sign off on the field's restart for fear unintended reservoir damage. There is currently uncertainty on whether the field will start up again.

The cause is believed to be poor connectivity between zones. Water injection is provided to the zone below for pressure support. However analysis is now showing low connectivity between the geological layers in the reservoir, and thus the water injection is not working effectively.

Wintershall started production from the Maria oil field on Haltenbanken in the Norwegian Sea in December 2017, one year ahead of schedule and with 20% reduction in costs. Maria was Wintershall’s first own-operated field in Norway.

Wintershall chose an innovative subsea concept to develop the field. Two subsea templates were installed on the seabed above the Maria reservoir and connected via a pipeline network to the existing Kristin, Heidrun, and Åsgard B platforms.

Energean targets Karish North

Energean is in the middle of drilling the Karish North prospect with results expected at the end of April 2019. The prospect is located c.5.4km from the Karish FPSO and is targeting 1.4tcfe. Assuming success and a discovery, Energean believes it would convert into 0.4bcm/y.

The FPSO is designed to handle 8bcm/y and Energean has so far secured 4.2bcm/y of offtake. It is expecting to finalise another 1.1bcm/y shortly, bringing contracted volumes up to 5.3bcm/y. Energean therefore has another 2.7bcm/y of capacity and Energean will look to contract this as soon as it is comfortable that it has more upstream gas volumes to underpin this.

Energean see lots of opportunity to sell more gas, led by the privatisation of Israeli power stations in the period 2019-22 which will open up 4.3bcm/y of demand.

Leveraging off Leverett

As part of the 30th Licensing Round, Zennor picked up Blocks 21/2d, 21/3c-d in licence P2350. The licence contains the Leverett discovery which was appraised by CNOOCNexen.

The discovery has had four wells and may or may not require further appraisal prior to development. The field could be tied back to Zennor's Finlaggan field and extend the plateau.

Leverett has been penetrated by:

• 21/2-2 - drilled in 1975 with the West Venture rig
• 21/2-4 - drilled in 1977 by Zapata with the Norjarl rig 
• 21/2a-11 - drilled in 2015 by Nexen with the Blackford Dolphin rig
• 21/3f-8 - drilled in 2013 by Nexen with the Transocean Prospect rig

Understanding Mozambique's fiscal regime (Part I)

Government take across countries in East Africa are generally below the Sub Saharan Africa average of 62%. This reflects the relative infancy of the E&P industry in the region with high exploration risk and uncertainties on the path to commericialising discovered resources. A lower fiscal take is required to attract investment.

Mozambique’s government take lies in the middle of its East African neighbours - lower than Uganda where significant oil reserves have been proved up, and Tanzania where fiscal terms are less attractive. Mozambique's fiscal take is uncompetitive relative to Kenya and Ethiopia, which are considered to be important E&P players in due course.

It is also important to note that Mozambique's resources are gas and hence deemed significantly less attractive than oil. Such large scale gas discoveries are expensive to monetise but clearly LNG is becoming an increasing focus by global IOCs and there has been enough momentum over the years to fianlly get Mozambique LNG off the ground.

Mozambique operates a standard PSC regime with an R-factor based on cumulative income/cumulative costs.
