Valeura Vitality Inc. on Monday declared three oil discoveries within the Gulf of Thailand, two within the Wassana discipline and one within the Nong Yao discipline.
In Wassana, the place Calgary Metropolis, Canada-based Valeura holds a 100% stake, the Niramai 4 effectively hit over 90 toes of oil payzone throughout two reservoirs, the corporate stated in a press launch. Niramai 4 was drilled to 7,312 toes. Niramai-4 sits about one kilometer (0.6 miles) northeast of the Niramai 1 discovery, in keeping with Valeura.
The second new discovery within the Wassana discipline, Niramai 4 ST1, is a sidetrack effectively of Niramai 4. Drilled 12,388 toes to check the separate Wassana North fault block north of the Wassana discipline, the sidetrack encountered round 40 toes of oil payzone, the general public exploration and manufacturing firm stated.
“The deepest oil-bearing zone is of specific curiosity in that the wellbore intersected the reservoir considerably downdip of the crest and oil is interpreted to be current to the bottom of the reservoir, with no oil-water contact recognized within the effectively”, Valeura stated of Niramai 4 ST1.
“This means additional potential, each deeper than penetrated, and extra laterally expansive within the updip portion of the construction”, it added.
“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 assist a further future improvement on the G10/48 block.
“Such a improvement enlargement is past the scope of the Wassana discipline re-development venture 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.
In the meantime within the Nong Yao D space, the Nong Yao 13 effectively found over 30 toes of oil payzone throughout a number of intervals after being drilled to five,399 toes of measured depth (3,342 toes of true vertical depth), Valeura stated.
“Importantly, this end result confirms that oil has efficiently migrated into this space of the block, an element that was seen to be a threat within the Nong Yao D space”, Valeura stated referring to the G11/48 block, the place it holds a 90 p.c working curiosity.
“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 information 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 improvement”.
Present manufacturing within the Nong Yao discipline is roughly 8,900 barrels per day (bpd) internet to Valeura, consisting of medium candy crude from Miocene-age reservoirs, in keeping with the corporate. The sector has been assessed to carry confirmed and possible reserves of 12.4 million barrels gross.
Valeura has mobilized the contracted rig that drilled the three new discoveries to 2 infill improvement wells on the Nong Yao A platform. “Thereafter, and as soon as commissioning work is full on the Nong Yao C Cellular Offshore Manufacturing Unit, the rig will start improvement drilling on the Nong Yao C accumulation”, Valeura stated. It targets to begin manufacturing in Nong Yao C within the third quarter.
Within the first quarter, Valeura produced 21,900 bpd, in keeping with its quarterly monetary outcomes launch revealed April 10.
“The elevated manufacturing displays sturdy efficiency of the brand new wells on the Wassana discipline, however was barely offset by shutdowns for scheduled upkeep at two of our fields to make sure ongoing world class requirements for integrity”, president and chief govt Sean Visitor stated in an announcement on the time. The 2 fields put offline had been the Jasmine and Manora fields in Thailand; Valeura additionally has belongings in Turkiye.
The outcomes announcement stated the 2 fields have been returned to manufacturing by the tip of the quarter, leading to an combination firm output charge of 23,000 bpd.
“Total manufacturing efficiency has been in step with administration’s plan, and accordingly, Valeura is happy to re-iterate its full yr 2024 manufacturing steering outlook of 21.5 – 24.5 mbbls/d”, Valeura stated within the April 10 information launch.
