ONGC to gear up on Redevelopment Mumbai High South Phase-3

ONGC to boost India Western Offshore oil production

2B1st_Project_Smart_Explorer_Sales_Pursuit_ToolThe State-owned Oil and Natural Gas Corporation Limited (ONGC) company has made the final investment decision (FID) to proceed with the Redevelopment Mumbai High South Phase-3 project as part of its program to boost the crude oil and natural gas production from the India Western Offshore fields in the Arabia Sea of the Indian Ocean.

In order to support India economical growth, ONGC is implementing its Perspective Plan 2030 (PP2030).

The purpose is to double the crude oil and natural gas production over the next two decades.

ONGC_Mumbai-High-South-Phase-3_MapBy 2030, ONGC is targeting to deliver 130 million tonnes of oil equivalent per year (toe/y) and to declare 1.3 billion toe of proven reserves

To do so, ONGC is considering to develop onshore and offshore oil and gas fields as well as explorer unconventional resources such as shale gas, coal bed methane (CBM) or high-pressure-high-temperature (HPHT) reservoirs.

This Perspective Plan 2030 will suppose ONGC to explore untapped resources and to perform full field developments on existing blocks.

In that respect, ONGC has decided to invest in the Western Offshore fields to escalate the production from the Mumbai High basin with the Redevelopment Mumbai High South Phase-3 project.

ONGC to go fast track with Mumbai High South Phase-3

With a third phase project estimated budget of $1 billion capital expenditure, ONGC is willing to expand Mumbai High South in 2030 with the additional capacity of:

 – 7.5 billion tonne of crude oil

 – 3.8 trillion cubic meter (tcm) of natural gas.

For the Redevelopment Mumbai High South Phase-3 project, ONGC will drill 36 new wells and 34 sidetrack wells.

To support this offshore production in the Arabia Sea, the Redevelopment Mumbai High South Phase-3 project should also include:

 – 3 wellheads platforms

 – 2 clamp-on facility for new wellheads on existing platforms

 – Export pipelines system

 – Modifications on 18 existing platforms

 In respect with the wellhead platforms already in operation, the three new ones will be tagged as RS-18, RS-20 and RS-21.

ONGC_Mumbai-High-South-Phase-3The export pipelines system will cover 115 kilometers subsea, therefore the corresponding package will include the installation.

The drilling operations will also tendered separately from the production infrastructures.

In respect with the size and complexity of the project, ONGC qualified foreign engineering companies, as well as India contractors with proven experiences in similar scale of project locally or overseas.

With Mumbai High North already in execution, ONGC is willing to implement the Redevelopment Mumbai High South Phase-3 project on fast track.

Assuming the engineering, procurement and construction (EPC) packages to be awarded on mid 2015, ONGC is targeting to run the Redevelopment Mumbai High South Phase-3 project into commercial operations by 2019.
