Crude oil production[1] during August 2021 was2518.56TMT, which is 5.98% lower than the target for the monthand2.29% lower when compared with production of August 2020.Cumulative crude oil production during April-August, 2021 was 12480.21TMT, which is 3.33% and 3.15% lower than the target for the period and production during the corresponding period of last year respectively. Unit-wise and State-wise crude oil production are given in Annexure-I. Unit-wise crude oil production for the month of August 2021 and cumulatively for April-August, 2021 vis-à-vis the same period of last year has been shown month-wise in Figure-1.
Unit-wise production details with reasons for shortfall are as under:
-
- Crude oil production by ONGC in the nomination blocks is less than monthly target of Aug’21 (6.31%) as well as April – Aug’21 target (3.79%). Also, it is less than actual production in corresponding month and period of last year i.e. Aug’20 (3.83%) & Apr-Aug’20 (4.64%). 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 anticipated production from Cluster-8 fields due to delay in inputs as installation of wellhead platforms delayed due to COVID-19 impact.
- Consequential loss in oil production due to conditions created by cyclone Tauktae.
-
- Crude oil production by OIL in the nomination blocks is higher than actual production in corresponding month and period of last year i.e. Aug’20 (4.34%) & Apr-Aug’20 (0.74%). However, it is less than monthly target of Aug’21 (3.33%) as well as April – Aug’21 target (1.91%). Reasons for shortfall in production as compared to target is as under:
- Less than planned contribution from workover wells, drilling wells and old wells.
-
- Crude oil production by Pvt/JVscompanies in the PSC/RSC regimeis less than monthly target of Aug’21 (6.15%) as well as April – Aug’21 target (2.69%). Also, it is less than actual production in corresponding month and period of last year i.e. Aug’20 (0.64%) & Apr-Aug’20 (0.64%). Reasons for shortfall in production as compared to target is as under:
- RAVVA (Cairn Energy India Ltd): Production shortfall is due to injectivity issues in few wells that caused the lower productivity.
- RJ-ON-90/1 (Cairn Energy India Ltd): Production is lower due to downtime on account of well failures and Diesel Generator breakdown across fields. Also, delay in polymer start up led to lower productivity.
- CB-ONN-2000/1 (GSPC): Not enough production from few wells due to reservoir issues and possible casing and sub surface assembly damage. Also, minor shortfall wells on account of power failure has affected the production.
- CB-ONN-2004/2 (ONGC): Two development wellscould not be drilled as planned in Q1 FY2021-22. Also, a newly developed well is under performing, thus, affecting the production rate.
- MB/OSDSF/B80/2016 (Hindustan Oil Exploration Company Ltd.): Delay in commencement of production.
