Tapti fields-I: 5 well head platforms to be decommissioned in 2018-19

The Panna-Mukta-Tapti (PMT) JV -- consisting of ONGC, RIL and BGEPIL as joint operators -- has started the process for decommissioning of five well head platforms in the Tapti field keeping in mind the fact that the Tapti gas fields have experienced a steep decline in their output and the production is likely to cease within a few months.
8The offshore Tapti block (1,471 km2) contains two fields, namely South Tapti and Mid Tapti, which have five wellhead platforms which are connected to the central processing complex TPP-TCPP via subsea pipelines.
8Each platform consists of a Jacket (steel support structure ~ 25 m in height resting on sea bed and extending above water, ~ 500 tonnes in weight) and the Topsides (above water steel structure welded to the Jacket, carrying few equipment, ~ 600 tonnes in weight).
8These structures are proposed to be removed from the Tapti field and transported to onshore by the PMT JV�s offshore works contractor for further onshore demolition, scrapping and disposal.
8BG, on behalf of the PMT JV, has invited Expression of Interest (EOI) from fabrication yard contractors, scrapping yard contractors or contractors having their own jetties, located on the Indian coast, for disposing the Tapti jackets and topsides (including topsides equipments) as per regulatory requirements. The last date for submission of offers is August 5, 2015.
8The five jackets and topsides each are proposed to be removed from Tapti offshore fields and transported to onshore around post-monsoon 2018 by a separate contractor appointed by the company.


Tapti fields-II: ONGC wants to utilize Tapti JV infrastructure

While the PMT JV has decided to decommission the five well head platforms in the Tapti field, no decision has yet been taken on the TCPP and TPP platforms which are part of the Tapti field infrastructure.
8ONGC wants to take up the TCPP and TPP platforms to process its gas coming from the Daman fields, including the C-Series gas.
8Approval for taking the gas to the Tapti JV facilities for processing is however yet to be approved by the petroleum ministry.
8As production from the Tapti gas fields is likely to cease within a few months, the equipment and assets which are no longer required for petroleum operations need to be first offered free of cost to the government or its nominee. 8The facilities come free of cost to ONGC as they have already been cost recovered by the PMT JV.
8It was on DGH's request that ONGC evaluated the option of taking over the Tapti JV facilities for production and processing of gas from its C-series discoveries and agreed to take over only the TCPP and TPP platform facilities.
8Along with the two platform facilities, the E&P major will also take over two spur lines (18" and 20") connected to the South Bassein Hazira Trunk (SBHT) lines (42" and 36") for the Daman development project, subject to the understanding that the abandonment and site restoration of balance facilities (wells, unmanned platforms and infield pipelines within the field which ONGC is not taking over) will be carried out by the PMT JV and adequate funds would be transferred to ONGC that would be required to abandon the facilities which ONGC is taking over.
