Valeura Energy has started offshore installation work for its Wassana field redevelopment in the Gulf of Thailand, bringing forward a key construction phase by approximately two months.
The company reported the start of offshore installation on 9 October 2026 through a social media update, according to Offshore Energy. The work forms part of the redevelopment of Block G10/48, where Valeura holds a 100% operated interest.
The installation follows the completion of the project’s new central processing platform (CPP) on 1 October 2026. The CPP and its supporting jacket were subsequently loaded onto vessels for offshore transportation and installation, as confirmed in Valeura Energy’s Q3 2026 Operations Update issued on 7 October.
An oil export pipeline connecting the new platform to a floating storage and offloading (FSO) vessel was installed in September, completing another part of the redevelopment’s offshore infrastructure.
The accelerated installation schedule was made possible after Valeura Energy finalised the necessary commercial arrangements and contractual amendments in September. These changes allowed the offshore installation campaign to be brought forward by approximately two months compared with the original development plan.
The company continues to target first oil from the new CPP around the beginning of the second quarter of 2027.
Development drilling is also scheduled to begin later this year. Valeura Energy has arranged for the Shelf Enterprise drilling rig charter to commence on 1 November 2026. The rig is expected to begin operations at the Nong Yao field, drilling through additional well slots at the Nong Yao A facility, before moving to Wassana for development drilling.
The new CPP is expected to support plateau production of approximately 7,500 bbls/d. Based on the accelerated start-up schedule, Valeura estimates that the redevelopment could deliver approximately 430,000 bbls of additional oil production in 2027 compared with its original plan.
Valeura Energy approved the Wassana redevelopment in 2025 to commercialise oil volumes beyond those accessible through the existing Ingenium mobile offshore production unit. The unit is expected to be decommissioned around the end of 2027.
The new platform is also designed to accommodate potential connections from future satellite production facilities, enabling additional oil accumulations north and south of Wassana to be considered for development.
The start of offshore installation marks the next stage of the Wassana redevelopment programme, with development drilling expected to follow later in 2026 and first oil targeted for early Q2 2027.
