Actual production from six Cauvery gas fields

Vol 4, PW 13 (02 Aug 00) Exploration & Production

Petrowatch learns there are three major constraints to production in the Cauvery project: an acute shortage of all sizes of casing pipes; frequent breakdown of cranes; and clearance from naval authorities for offshore work.

Exploration aside, actual gas production in the Cauvery basin is showing a healthy rise. The following numbers illustrate production from six major gas producing fields in the Cauvery basin between April 1999 and April 2000.

Periyapattinam-3 Object-II (2,030-2,027m). Nannilam formation.

Produced 77,000 cubic metres per day (cm/d) and 2 cm/d condensate through 6 mm BEAN Kuttanallur-3 Object-II (1,952-1,949 and 1,946-1,937m). Kamalapura formation.

Produced 46cm/d oil, API 37 degrees and 2,500cm/d of gas, through 6mm BEAN Kuthalam-6 Object-III (2,572-2,569 m, 2,565-2,565m, 2,559-2,555m, 2,552-2,549m and 2,545-2,541m). Andimandam formation produced 60,000cm/d gas and 6cm/d condensate through 6mm BEAN Object-IV (2,528-2,520m, 2,518-2,516m and 2,508-2,504m).

Andimadam formation produced 63,000 cu m/d gas and 7 cu m/d condensate through 6mm BEAN Tiruvarur-14 Tiruvarur-14: Object-III (2,617-2,609m). Nannilam formation produced 85cm/d oil (API 36 degrees) and 11,000 cm/d gas through 6mm BEAN Perungulam-4 Object-II (2,115-2,106 m).

Nannilam formation produced 84,000cm/d gas through 6mm BEAN Adiyakkamangalam-16 Object-II (2,366-2,363m) produced 28,500 cm/d gas. 3cm/d condensate (API-52.9 deg) and 11cm/d water with salinity 122,850 ppm through 6mm BEAN
