Santos operates the Van Gogh, Coniston and Novara fields via a Floating, Production, Storage and Offtake (FPSO) facility; the Ningaloo Vision (NV). The Van Gogh, Coniston and Novara Drilling and Completions Environment Plan (EP) is a five-year drilling EP to drill up to six additional wells in the licence area WA-35-L and WA-55-L. The EP was accepted by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) in November 2016. In 2018, two production wells were drilled under the EP and Santos now proposes to drill three additional dual lateral wells under the same drilling EP.

Installation activities to tie these three new wells back to the NV production facility is the subject of this EP.

The scope of this EP covers the installation activities needed to tie in the three new dual lateral wells into the existing infrastructure at Drill Centre 1 (DC1) and Drill Centre 2 (DC2), including well installation, pre-commissioning, cold commissioning and surveys. Following completion of the activities under this EP, production operations are covered under the NOPSEMA accepted Ningaloo Vision Operations EP.

The VGID2 installation will take place entirely within production licence WA-35-L. Activities associated within the scope of this EP will be conducted within a defined ‘Operational Area’, which is a 500 m radius around DC1 and DC2 respectively and shown in the location map. DC1 and DC2 are situated around 2 km apart in an approximate water depth of 380 m. They are located approximately 45 km from the North West Cape and 110 km from the town of Onslow Western Australia.

VGID2 installation activities will be undertaken in two campaigns:
+ Campaign 1 (DC1), estimated 9 days
+ Campaign 2 (DC2), estimated 13 days

Allowing for weather and operational delays, the total time required to install the wells could be up to 50 days. The earliest date for commencement of the activity is Q2 2021 with all activity completed on, or before 31st December 2022.
