The Nong Yao C discipline extension undertaking within the Gulf of Thailand has achieved full output capability at 13,400 barrels per day (bpd), operator Valeura Vitality Inc. mentioned, growing the corporate’s portfolio-wide internet manufacturing by practically 25 p.c.
The Canadian oil and gasoline exploration and manufacturing firm owns 12,100 bpd of the gross manufacturing as a 90 p.c stake proprietor of License G11/48. Native participant Palang Sophon Ltd. holds the remaining 10 p.c.
Earlier than the startup of Nong Yao C, Valeura was deriving 8,900 bpd internet from the Nong Yao discipline. With the manufacturing ramp-up of the southern extension undertaking, achieved days after Valeura introduced startup earlier this month, the corporate has seen a rise of virtually 25 p.c in portfolio-wide internet manufacturing.

“This manufacturing, when mixed with the Wassana discipline being again on-line has resulted in steady combination oil manufacturing over the previous week of 26.2 mbbls/d (Firm’s working curiosity share, earlier than royalties)”, it mentioned in a press release on its web site.
Wassana, below Valeura’s 100%-owned G10/48 block, was shut down late June to make sure security whereas an inspection was being carried out on an anomaly within the discipline’s cell manufacturing unit. Asserting restart August 2, Valeura recognized the fault as a “superficial” weld crack.
For the second quarter, Valeura averaged simply over 21,000 bpd in manufacturing, in accordance with its quarterly report launched August 8.
Six wells have now been put onstream in Nong Yao C. “A seventh properly is predicted to be began throughout the coming weeks, to create spare manufacturing capability”, president and chief govt Sean Visitor mentioned.
Nong Yao had confirmed and possible reserves of 12.4 million barrels gross as of yearend 2023, in accordance with Valeura.
For the remainder of the 12 months Valeura additionally plans to drill infill wells in two different fields within the Gulf of Thailand, Jasmine and Manora, to offset declines. Jasmine, one in all two producing fields in Valeura’s 100%-owned License B5/27, and Manora of License G1/48, during which Valeura holds a 70 p.c working curiosity, returned on-line within the second quarter after scheduled upkeep.
New Discoveries
Final April Valeura declared three oil discoveries within the Gulf of Thailand, two within the Wassana discipline and one in Nong Yao.
In Wassana, the Niramai 4 properly hit over 90 ft of oil payzone throughout two reservoirs, the corporate mentioned. Niramai 4 was drilled to 7,312 ft. Niramai-4 sits about one kilometer (0.6 miles) northeast of the Niramai 1 discovery.
The second new discovery in Wassana, Niramai 4 ST1, is a sidetrack properly of Niramai 4. Drilled 12,388 ft to check the separate Wassana North fault block north of the Wassana discipline, the sidetrack encountered round 40 ft of oil payzone.
“Whereas reservoir properties and volumetric estimates are nonetheless being calculated for each wells, when mixed with the pre-existing Niramai volumes, the full recoverable volumes are believed to exceed administration’s necessities to help an extra future growth on the G10/48 block”, Valeura mentioned in a press launch April 15.
“Such a growth growth is past the scope of the Wassana discipline re-development undertaking at the moment being evaluated, however has the potential to increase manufacturing and the lifetime of the concession past its present financial restrict in 2032”.
Valeura expects so as to add the brand new volumes to its yearend reserves declaration.
Within the Nong Yao D space, the Nong Yao 13 properly found over 30 ft of oil payzone throughout a number of intervals after being drilled to five,399 ft of measured depth (3,342 ft of true vertical depth), Valeura mentioned.
“Importantly, this end result confirms that oil has efficiently migrated into this space of the block, an element that was seen to be a danger within the Nong Yao D space”, Valeura mentioned.
“The actual intervals comprising the invention are comparatively shallow new zones which haven’t been produced elsewhere on the concession.
“These reservoirs are believed to be recurring throughout the Nong Yao D space and additional evaluation on the seismic knowledge is warranted. This work will search out potential areas for follow-up exploration and appraisal drilling within the neighborhood, with the final word goal of amassing adequate volumes to justify a future growth”.
