This paper presents the successful delivery of Jitang Field Development project, a marginal field located offshore Peninsular Malaysia. Vestigo Petroleum Sdn Bhd (Vestigo), a wholly owned subsidiary of Petronas Carigali Sdn Bhd (PCSB) as operator of the field has set-up a new benchmark in Malaysia when Jitang field commenced production in January 2020:

The first in Malaysia to leverage on existing surface facilities via re-using/relocating Wellhead Platform (WHP)

Commenced production within 13 months from project's Final Investment Decision (FID)

Utilising suction pile technology and novel transport and installation (T&I) methodology to relocate the substructure and topsides of the WHP in a single piece from original to new location

Development of Jitang field consists of a WHP, an FPSO and a flowline evacuating full well stream from four wells. This paper will focus on WHP as the relocation of the WHP is the main feature and key driver of the project. Technical due diligence effort that was done in mitigating risks are also emphasized.

Vestigo's experience of re-using an existing WHP upon decommissioning the facility and re-installing it at a new location for re-use; proven that the concept works for effective solution of marginal field development. Jitang project has demonstrated significant improvement in project delivery schedule and cost saving.
