2. 2 Realisasi Pengeboran Eksplorasi tahun 2024 Year To Date (21 Jun 2024) 17 Sumur Telah Tajak dari Plan WP&B sebanyak 21 Sumur di Semester I 2024 (81%) Outlook End of Year 44 Sumur Tajak dari Plan WP&B sebanyak 50 Sumur di 2024 (88%) Plan WP&B 2024 Actual Forecast 17 sumur 21 sumur 44 sumur 50 sumur Plan WP&B 2024 Semester I Semester II Jumlah Sumur Tajak 21 29 Catatan: Dari rencana awal WP&B 2024, terlihat jumlah pengeboran eksplorasi mulai agresif pada Semester II Tahun 2024 (58% di semester II). Hingga semester I 2024, telah berhasil direalisasikan tajak 17 sumur eksplorasi dari target 21 sumur tajak di Semester I 2024 (81% dari plan WP&B). Realisasi Realisasi 21.06.2024 Outlook 31.12.2024 Jumlah Sumur Tajak 17 44 Peta Sumur Eksplorasi 2024 Berdasarkan hasil monitoring hingga 21 Juni 2024, diperkirakan outlook realisasi tajak sumur eksplorasi di tahun 2024 adalah sebanyak 44 sumur eksplorasi (88% dari rencana tajak 50 sumur pada WP&B 2024).

The flowback process is ongoing and being reported to Subholding Upstream. Follow-up is expected to be completed. It is most likely that PHR will opt for the extended 6-week flowback (minimum req from EOGI) rather than the 2-week option. PHR will still push for 12 weeks.
