Production of Natural Gas

Natural gas production during December 2021 was 2896.69 MMSCM, which is 19.45% higher than the production of December 2020 but 14.93% lower than the monthly target. Cumulative natural gas production during April-December 2021 was 25673.90 MMSCM, which is 21.51% higher than production during corresponding period of last year but 8.75% lower when compared with target for the period. Unit-wise and state-wise natural gas production is given at Annexure-II. Unit-wise natural gas production for the month of December 2021 and cumulatively for April-December 2021 vis-à-vis same period of last year has been shown in Table-2 and month-wise in Figure-2.

Figure-2: Monthly Natural Gas Production

1. Natural gas production by ONGC in the nomination blocks during December 2021 was 1757.10 MMSCM, which is 12.54% lower than target for the month and 5.42% lower than the production of December 2020. Cumulative natural gas production by ONGC during April-December, 2021 was 15541.83 MMSCM, which is 11.13% and 6.06% lower than target for the period and production during corresponding period of last year respectively. Reasons for shortfall in production are as under:

• Less than anticipated production from WO-16 cluster due to delay in mobilization of MOPU Sagar Samrat.
• Less than planned production from Vasistha /S1 wells in EOA due to certain reservoir related issues.
• Delay in commencement of gas production from U1 field of KG-98/2 Cluster-II due to covid impact as manufacturing of subsea items and well completion got delayed.
• Less production due to decline in Tapti-Daman block.
• Less production in Mandapeta field due to delay in inputs and decline in production from Pasarlapudi & Endamuru fields in Rajahmundry.

2. Natural gas production by OIL in the nomination block during December 2021 was 240.37 MMSCM which is 19.21% higher than target for the month and 4.32% lower than the production of December 2020. Cumulative natural gas production by OIL during April-December 2021 was 2189.77 MMSCM, which is 17.11% higher than production during corresponding period of last year but 1.49% lower than target for the period. Reasons for shortfall in production are as under:

• Less than planned contribution from workover wells and drilling wells.

• Less offtake by the consumers in main producing area (MPA).

3. Natural gas production by Pvt/JVs companies in the PSC/RSC/CBM regime during December 2021 was 899.22 MMSCM, which is 145.98% higher than the production of December 2020 but 21.46% lower than the target for the month. Cumulative natural gas production by Pvt/JVs during April-December 2021 was 7942.31 MMSCM, which is 192.55% higher than production during corresponding period of last year but 5.73% lower than target for the period. Reasons for shortfall in production are as under:

• KG-DWN-98/2 (ONGC): Delay in commissioning of Wells U1-A of KG-DWN-98/2 block. Well U1-2 (U1-B) producing less than the estimated profile.
• RJ-ON-90/1 (Cairn Energy India Ltd): Few Gas wells of RDG field are not producing as per expectations.
• RANIGANJ EAST (Essar Oil and Gas Exploration and Production Ltd.): Shortfall because delay in scheduled operations.
• KG-DWN-98/3 (RIL): Workover job ongoing in well No. AR1-DEV1.
