Zama resource increase

Talos and Premier Oil have announced the successful appraisal of Zama in Block 7 offshore Mexico under the Zama-3 well. Premier has indicated a P90-P10 resource range of 670-970mmboe with P50 of 810mmboe. This further reaffirms the resource base and provides an upgrade to the previous 600mmbbl (oil) estimate.

The Zama-3 well follows:

• The initial Zama-1 discovery in 2017
• Zama-2 appraisal in January 2019
• Zama-2ST1 sidetrack well in April 2019

Zama-3 was drilled 2.4km from Zama-1 and logged 228m of gross pay. The net-to-gross was consistent with prior penetrations. The Zama-3 well was completed 9 days ahead of schedule and on budget.

The entire 3 appraisal well programme finished 39 days ahead of schedule and under budget.

The Zama field is planned to be developed from a single drill centre with drilling from the platform. Three production platforms are envisaged, each with capacity of up to 100mbopd. Produced oil is planned to be transported via a pipeline to the Dos Bocas terminal located onshore, c.70km away from the field.

The Zama partners are: Talos (35% operator), DEA (40%) and Premier Oil (25%).

Premier Oil also has a non-operated interest in Block 30 which could see Mexico transform into another important leg of its portfolio.

Further positive momentum at Zama

The Zama-2ST1 well (side-track well son Zama-2) encountered 873ft of gross oil bearing column with a net-to-gross ratio of c.70%. The well flowed at 7.9mboepd of which 94% was light 26-30 API oil. The well results indicated a prolific reservoir and potential to achieve significant plateau rates at the field. The operator estimates that a peak production of 150-175mboe/d is achievable.

This news is positive for the recoverable reserves of the field and could tighten the current estimates range of 400-800mmboe upwards.

The rig will now move to drill the Zama-3 well, the last in the 2019 campaign, and should confirm the extent of the field to the south. The drilling programme remains ahead of schedule with the Zama-2ST1 completed 9 days ahead of schedule and 16% below budget.

The Zama field is planned to be developed from a single drill centre with drilling from the platform. Three production platforms are envisaged, each with capacity of up to 100mbopd. Produced oil is planned to be transported via a pipeline to the Dos Bocas terminal located onshore, c.70km away from the field.

The Zama partners are: Talos (35% operator), DEA (40%) and Premier Oil (25%).

For Premier Oil, this development could overtake the Sea Lion development in the Falklands (another large resource optionality for the company), adding visibility to additional near-term production growth.

Premier Oil also has a non-operated interest in Block 30 which could see Mexico transform into another important leg of its portfolio.

Block 30 is operated by DEA 40% with partners Premier Oil 30% and Sapura Energy 30%.

Premier success at Zama

Premier and operator Talos have announced the successful appraisal of Zama-2 offshore Mexico. This is the second well on the Zama field, following the initial discovery at Zama-1 in 2017, and reaffirms the massive 600mmbbl oil discovery.

The well penetrated 152m of net pay with a high net-to-gross of 73% (vs. Zama-1 of 63%). This suggests potential resource upside and could see resource estimates being upgraded as the appraisal campaign continues.

Zama-2 will now be sidetracked to penetrate the reservoir vertically to aid coring and testing. The upcoming Zama-3 well will appraise the southern portion of the accumulation. With good confidence on the underlying resources, the Zama partners should now be thinking ahead on development plans.

The Zama field is planned to be developed from a single drill centre with drilling from the platform. Three production platforms are envisaged, each with capacity of up to 100mbopd. Produced oil is planned to be transported via a pipeline to the Dos Bocas terminal located onshore, c.70km away from the field.

For Premier Oil, this development could overtake the Sea Lion development in the Falklands (another large resource optionality for the company), adding visibility to additional near-term production growth.

The Zama partners are: Talos (35% operator), Sierra Oil & Gas (40%), Premier Oil (25%).
Sierra Oil & Gas was recently acquired by DEA.

Petsec increases interest in Block 7 offshore Yemen to 100%

Petsec has acquired Oil Search's 40% interest in Block 7.

Full announcement below.

Petsec Energy has completed the transaction with Oil Search to acquire all of the shares of its subsidiary Oil Search (ROY) Limited which holds a 40% working interest (34% participating interest) in the Al Barqa (Block 7) licence and operatorship, in the Republic of Yemen.

Completion of the Oil Search agreement follows the 2016 transaction with KUFPEC (25% working interest) to acquire their interests in Block 7, and the transactions with AWE (25% working interest) and Mitsui E&P Middle East (10% working interest) completed and approved by the Yemen Ministry of Oil and Minerals in 2014. The acquisition of Oil Search (ROY) Limited increases Petsec’s potential working interest in Block 7 to 100% and operatorship of the block.

Block 7 is an onshore exploration permit covering an area of 5,000 sq kms (1,235,527 acres) located approx. 340 kms East of Sana’a, 80 kms North East of the Company’s Damis (Block S-1) Production Licence, and 14 kms East of OMV’s Al Uqlah (Habban) Oilfield. The block contains the Al Meashar oil discovery made by Oil Search in 2010 as well as an inventory of nine prospects and leads defined by 2D and 3D seismic surveys, with target sizes ranging from 2 to 900 MMbbl oil gross.

The Al Meashar Oilfield, with a target resource of 11 MMbbl to 50 MMbbl, contains two suspended discovery wells that intersected over an 800 metre oil column which in 2010-11 delivered flow rates ranging from 200 to 1,000 bopd in short-term testing of the wells. The oil column extends over the same reservoir sequence as that of the Habban Oilfield in the adjacent Al Uqlah (Block S-2).

Petsec Energy has secured a 100% interest in two production and exploration licenses in the highly productive Shabwah Basin in Central Yemen, Blocks S-1 and 7, which contain six oil & gas fields – one developed and five yet to be developed, with cumulative target resources between 45 and 84 million barrels of oil and 550 billion cubic feet of gas, in addition to further high potential exploration targets.

Block 7 is a key addition to the Company providing material upside to Petsec’s existing Production Licence, Damis (Block S-1) acquired in February 2016 from Occidental Petroleum, which holds the developed An Nagyah Oilfield and four undeveloped oil and gas fields, containing substantial oil and gas resources in excess of 34 million barrels of oil and 550 billion cubic feet of gas. The developed AnNagyah Oilfield was estimated, based on limited production rates of 5,000 bopd for trucking purposes, by DeGolyer and MacNaughton, reserve engineers, to contain gross 2P reserves of 12.8 MMbbl, of which the financial net to Petsec Energy is 5.6 MMbbl of oil, having a NPV 10 of US$155.4 million based on January 2016 forward oil prices.

Petsec’s Chairman, Mr Terry Fern stated:

'We are pleased to have secured the acquisition of 100% of both Blocks 7 and S-1 so we can now concentrate on bringing these acquired oil and gas fields into production. This oil and gas production is critically important to the local Yemeni people to provide employment and revenues, absent since 2015 because of the country’s political issues. We were heartened by the recent welcome and encouragement we received from senior members of the Yemen Government currently based in Riyadh, Saudi Arabia, and hope this offered support will allow the early restart of production of the An Nagyah Oilfield, which will demonstrate to the World that foreign investment is welcome in Yemen, and will encourage other foreign oil companies to join us in rebuilding the Yemen oil industry. We look forward to working with the Ministry of Oil & Minerals in developing Yemen’s oil and gas industry.'
