Activity Description
BHP Petroleum (Australia) Pty Ltd (BHP) proposes to undertake infill development drilling activities at the Crosby South Well Centre (Crosby-3H1 and Crosby-4H2 well locations) and at the Stickle Well Centre (Stickle-4H1 well location) within production licence area WA-42-L in Commonwealth waters. The closest landfall is the North West Cape peninsula, Exmouth, approximately 27 km to the south-east.

The proposed activities are located approximately 13 km outside the northern boundary of the Ningaloo Marine Park. The water depth in the operational area is approximately 200 m. The proposed petroleum activity represents Phase 4 of the ongoing development of the Pyrenees field development program and includes well intervention for purposes of water shut-off at Crosby-3H1 location, two horizontal side-track laterals at the Stickle-4H1 well location and potentially a contingent side-track lateral at the Crosby-4H2 well location. The operational area for the petroleum activity is a 2 km radius around each of the two well centres. The operational area sets the spatial boundary within which the activity will occur. The proposed activity is to be undertaken using a semi-submersible mobile offshore drilling unit (MODU).

The earliest expected commencement date for infill drilling activities is Q2 2022, although for contingency purposes due to MODU availability and weather constraints, this EP allows for the petroleum activity to occur any time between over calendar years 2022 and 2023.

The proposed activities will be short in duration, with the MODU expected to be on location in the production licence area for approximately 3-4 months, contingent on final activity scope, weather conditions and unforeseen circumstances. The activity will be undertaken 24 hours a day, 7 days a week.
