The PY-3 field is located off the east coast of India 80 km south of Pondicherry in water depths between 40 m and 450 m. The Cauvery Basin was developed in the late Jurassic/early Cretaceous period and straddles the present-day east coast of India. The licence, which covers 81 km2, produces high quality light crude oil (49° API).

The field was developed using floating production facilities and subsea wellheads, a first for an offshore
field in India. The facility at PY-3 consists of the floating production unit, ‘Tahara’, and a 65,000 DWT tanker, ‘Endeavor’, which acts as a floating storage and offloading unit. There are four sub-sea wells tied back to Tahara. Tahara has a three-stage crude oil separation system, with the first two stages being three-phase separators and the third stage a two-phase separator.

Liquid processing capacity on Tahara is 20,000 bbld with 17 mmscfd of gas handling capacity. The field currently produces associated gas in the range of 3.5 mmscfd.  This produced gas is used as fuel gas with excess gas being flared. The stabilised crude oil is pumped from Tahara to Endeavor for storage and offloading to shuttle tankers. Crude oil from the PY-3 field is sold to CPCL at its refinery in Nagapattinam, approximately 70 km south of the PY-3 field.

The PY-3 offshore oilfield was discovered on licence CY-0S 90/1 by ONGC in 1988 and, as a result of the
development programme instituted by HEPI, was brought into production in November 1997.


HEPI is the Operator of the PY-3 field, and is party to a PSC together with ONGC, TATA and HOEC. The
