Eni SPA reported that the Zohr 5x well, which was drilled to a TD of 4,350 m in 1,538 m of water offshore Egypt, has proved the presence of a carbonatic reservoir and natural gas accumulation in the southwestern portion of the Zohr megastructure.
The fifth well drilled on the Zohr structure on Shorouk block, Zohr 5x encountered a 180-m continuous hydrocarbon column in the carbonate sequence with excellent reservoir characteristics, the Italian firm says.
The results confirm that Zohr field could hold a potential 30 tcf original gas in place. Zohr 5x is 12 km southwest of the Zohr 1x discovery well (OGJ Online, Aug. 31, 2015).
Zohr 5x also was successfully tested by opening 90 m of reservoir section to production. Data collected during the test confirmed the deliverability of the Zohr reservoir, in line with the Zohr 2 well test, producing more than 50 MMscfd of gas limited only by the constraints of the production facilities.
In the production configuration, the well is estimated to deliver as much as 250 MMscfd.
The Zohr drilling campaign will continue this year with a sixth well to ensure the accelerated startup production rate of 1 bcfd. The project is on schedule to begin production by yearend 2017.
Eni, through its subsidiary IEOC Production BV, holds 100% stake in Shorouk block. Belayim Petroleum Corp. (Petrobel) is operating on behalf of Petroshorouk, an equal joint venture of IEOC and Egyptian Natural Gas Holding Co.
Petrobel in August let a contract to Frames Group BV for processing equipment for a gas plant connected to Zohr’s first phase of development (OGJ Online, Aug. 19, 2016).
