PT Lapindo Brantas Inc is an Indonesian oil and gas exploration company, initially established as a joint venture between PT. Energi Mega Persada Tbk. (50%), PT. Medco Energi Tbk. (32%) and Santos Australia (18%). The Bakrie family, through its investments, held a controlling stake in PT. Energi Mega Persada Tbk. Lapindo Brantas currently employs a staff of 77 permanent and contract employees and 142 personnel working for the company through a third party contract.
It operates in the Brantas Block in East Java, Indonesia where its working site covers 3,042 km2. encompassing two onshore and three offshore sites:
Area-1: Kediri Regency, Nganjuk Regency and Jombang Regency (onshore)
Area-2: Sidoarjo Regency, Pasuruan Regency and Mojokerto Regency (onshore)
Area-3: Probolinggo Regency and Situbondo Regency (offshore)
Area-4: Probolinggo Regency and Situbondo Regency (offshore)
Area-5: Probolinggo Regency and Situbondo Regency (offshore)
As of January 2011, approximately 20.58 MSTB of oil and gas has been produced by LBI from its two productive areas.
The 2009 CITYGAS project by Lapindo supplies households in East Java with a steady supply of natural gas through a built in pipeline infrastructure to complement the Indonesian government's policy and gas initiative to reduce dependence on kerosene as an energy source. The project involved a contract with the Director General of Oil and Gas to sell 8MMSCFD of gas to "City Gas" to supply households in surrounding villages of Surabaya and to encourage the switch to LPG.
After the Sidoarjo mud flow disaster, Lapindo Brantas took over responsibility in covering the cost of emergency response and victim resettlement, paying more than Rp. 5 trillion (approx. USD 550 million) despite its acquittal as the cause of the mudflow in 2009 by Indonesia's Supreme Court. Uncertainty surrounds the exact cause of the eruption, with scientists and geological experts unable to reach a unanimous conclusion. Some argue it was the result of drilling while others support the theory that its cause was a natural disaster linked to the reactivation of Mt. Semeru in nearby Yogyakarta.
