Empyrean is the operator of Block 29/11 in China and has 100% working interest during the exploration phase. In the event of a commercial discovery, its partner, CNOOC, has a back in right to a 51% participating interest in the development and production phase.

In order to ensure safe and secure drilling operations, the Company has held several discussions and has remotely held meetings with CNOOC EnerTech in order to secure its services to assist with the pre-drill logistics and management of the drilling operations. These discussions resulted in defining a broad mandate for the engagement with the following three teams being formed to work in a phased manner to coordinate and manage the drilling operations:

The Onshore team will be responsible for finalising the drilling and geological program for the well in line with CNOOC's requirements. In addition, this team will be responsible for applying for and securing all necessary permits ahead of drilling operations. Finally, this team will develop safety and emergency response procedures and documentations. The Onshore team has already commenced systematic work for securing several drilling permits, and have commenced engagement with COSL drilling group for verification of wellhead and casing specifications. CNOOC EnerTech team is also preparing a comprehensive Emergency Response Plan ("ERP") for conducting safe drilling operations.

The Offshore team will join the Onshore team 15 days prior to rig mobilisation to the drilling location, and will be involved in managing day-to-day drilling operations on the rig.

In the event there is an oil pay in the well (success-case), a Well Test team will join the Offshore team in the rig, and will be responsible for the comprehensive well testing operations.

The information contained in this announcement has been reviewed by Empyrean's Executive Technical director, Gaz Bisht, who has over 31 years' experience as a hydrocarbon geologist and geoscientist.
