TIMOR GAP has been carrying out and evaluating technical studies for offshore blocks which are currently in open acreage released by the ANPM in order to evaluate the most optimal sites for operations and production.
PSC TL – SO – 19 – 16
TIMOR GAP, through its whole owned subsidiary TIMOR GAP Chuditch, Unipessoal, Lda and Joint Venture partner, SundaGas Banda Unipessoal, Lda. signed a PSC for the TL-SO-19-16 (PSC 19-16) contract area on 8 November 2019 with the ANPM, on behalf of the Ministry of Petroleum and Minerals.
The purpose is to begin appraisal of the Chuditch gas discovery field and exploration of adjacent prospective areas within Chuditch discovery field, covering an approximately of 3,571.5 km2 area in a water depths of 50-100 meters. The reservoir target for the Chuditch gas field is approximately at a depth of 2900 m from the seabed.
Partners:
The Joint Operation Agreement (JOA) between TIMOR GAP Chuditch UL and SundaGas Banda UL was signed on 27 November 2019. The PSC 19-16 became effective on 19 December 2019 upon approval from ANPM.
Initial discovery by Shell in 1998 showed that the field contains a 25-meter gas column and is estimated to contain of 0.7 to 1.6 TcF of recoverable gas. The PSC 19-16 JV partners have committed to a seven-year Exploration Work Program with the Minimum Exploration Work Requirements stipulated in three periods:
- Initial Period (Years 1-3) envisages seismic reprocessing (pre-stack depth migration) of 800 km² of 3D seismic data and a 2000 km line of 2D seismic data, geological and geophysical studies and one appraisal well, subject to positive seismic reprocessing result that supports the presence of a significant structure associated with the Chuditch discovery.
- Second Period (Years 4-5) includes post-well evaluation study and drilling of one (1) exploration well, and development scenario planning for Chuditch discovery
- Third Period (Years 6-7) comprises geological and geophysical studies, development scenario planning and drilling of two exploration or appraisal wells.
The Operator, SundaGas, is carrying out a seismic reprocessing. As of 6 December 2021, the seismic reprocessing has achieved 49% completion, including the time pre-processing and depth velocity model building covering the complex shallow carbonate pick. Additionally, a fast-track 3D PSDM volume was delivered to TIMOR GAP office on 3 December 2021. The reprocessing work is expected to be completed around the middle of 2022 and then SundaGas and TIMOR GAP Chuditch will interpret those data for a better understanding of the Chuditch discovery.
PSC TL – SO – T 19 – 11
TIMOR GAP signed its first PSC in 2013, through its wholly owned subsidiary TIMOR GAP PSC 11-106, to begin the process of exploration and development of petroleum resources in a block located in the former Joint Petroleum Development Area (JPDA). The area includes proven but untouched reserves such as Jahal, Kuda Tasi Squilla and Krill fields, in addition to other prospective fields for exploration.
The block has a few discoveries, proven but unproduced reserves at Jahal, Kuda Tasi, in addition to a few prospects such as Kanase, Karungu, Squilla and Krill, with approximately cumulative of more than 500 MMbbls and other prospects yet to be explored.
Kanase-1 prospect was drilled in 2019. However, this well encountered a few technical problems and resulted in its unsuccessful conclusion. Further, with the flow of information from Kanase-1 drilling campaign, the Operator (ENI) together with its Joint Venture (INPEX and TIMOR GAP) decided to proceed in conducting detail studies of the prospects that lies within the block for better understanding the quality of the data as well as technical parts, such as Geological & Geophysical (G&G) data and Petroleum System.
One of the main activities performed during 2021 consisted of the application for another 24-months PSC extension submitted to ANPM, which was granted by the latter in August 2021 to the Operator and its Joint Venture, to perform detailed studies on the prospects within this PSC contract area.
Furthermore, in 2021, the Joint Venture also carried out a few technical studies, namely finalization of permit wide re-interpretation across the PSC on the available PSDM and PSTM seismic data sets and review of prospectivity within PSC 19-11, with evaluation and risking of prospects including all play elements (reservoir, seal, charge, and trap).
PSC TL – SO – 15 – 01
TIMOR GAP’s wholly owned subsidiary, TIMOR GAP OFFSHORE BLOCK, Unipessoal, Lda, was awarded with PSC TL-SO-15-01 in 2015, through the Ministerial Dispatch No.3/GMPRM/XII/2015, of 18 December, holding a participating interest of 100% in this offshore PSC. Exclusive hydrocarbon exploration rights were granted to TIMOR GAP Offshore Block through the Government Resolution n. 44/2015, of 22 December, including an authorization to carry out a multi-client 3D seismic survey in the referred offshore block.
PSC TL-SO-15-01 is located in the Timor-Leste exclusive maritime jurisdiction. A 2780 square kilometers Crocodile 3D seismic survey was acquired in 2016 and the full prospectivity assessment was performed by CGG GeoConsulting, including interpretation of the 3D seismic data, AVO analysis, play analysis, prospect ranking and economics. The seismic surveys results indicated a “world-class prospectivity” in the block allowing the imaging of 31 individual closed seismic structures at various geological levels (Jurassic, Triassic and Permian), frequently stacked vertically, in 17 geographically distinct locations (11 Plover Fm prospects, 11 Triassic prospects and 9 Permian prospects), with most locations having multiple targets.
The pilot project was completed in 2021 by Full Wave Field Inversion (FWI) and Time Reverse Migration (RTM) on Baleia prospect, showcasing excellent results. The results will be incorporated to finalize the prospectivity report of the block and will be dealing with third party to assist with virtual data-room to host the relevant data and reports for farm-out activities.
