Human error to blame for Indonesia’s mud volcano: scientists

Scientists Friday unveiled fresh evidence that gas drillers were to blame for unleashing a mud volcano in Indonesia’s East Java that claimed 14 lives and displaced tens of thousands of people. 

In a paper published by the journal Marine and Petroleum Geology, a group led by experts from Britain’s Durham University said the new clues bolstered suspicions the catastrophe was caused by human error.

The company being fingered for the disaster, drilling firm Lapindo Brantas, replied in the same journal that the “Lusi” mud volcano was unleashed by an earthquake at Yogyakarta, 280 kilometres (174 miles) away.

Lusi’s mud has been devouring land and homes in Sidoarjo district since May 2006, imperilling as many as 100,000 people through subsidence and inflicting damage at 4.9 billion dollars, according to an estimate by an Australian expert.

Durham professor Richard Davies said drillers, looking for gas nearby, had made a series of mistakes.

They had overestimated the pressure the well could tolerate, and had not placed protective casing around a section of open well.

Then, after failing to find any gas, they hauled the drill out while the hole was extremely unstable. By withdrawing the drill, they exposed the well hole to a “kick” from pressurised water and gas from surrounding rock formations.

The result was a volcano-like inflow that the drillers tried in vain to stop, he said.

“We found that one of the on-site daily drilling reports states that Lapindo Brantas pumped heavy drilling mud into the well to try to stop the mud volcano,” Davies said in a press release.

By pumping in this heavy mud, the drillers had hoped to create sufficient pressure in the column of the well hole to block the fluid pouring in from the rupture, said Davies.

“This was partially successful, and the eruption of the mud volcano slowed down. The fact that the eruption slowed provides the first conclusive evidence that the bore hole was connected to the volcano at the time of eruption.”

He added: “This is the clearest evidence uncovered so far that the Lusi mud volcano was triggered by drilling. We have detailed data, collected over two years, that show the events that led to the creation of the Lusi volcano.”

A co-author of the discussion paper, Michael Manga, a professor at the University of California at Berkeley, added the Yogyakarta quake was too small and distant to have caused Lusi.

“The stresses produced by the earthquake were minute — smaller than those created by tides and weather,” he said.

Arguments over the causes of Lusi have become a political issue in Indonesia.

The row has hamstrung payments of compensation to people forced from their homes and farmers and factory owners who have lost agricultural land and property to the sea of mud.

Australian specialist Mark Tingay of Curtin University of Technology said last year that Lusi was filling the equivalent of 50 Olympic-size swimming pools every day and could continue spewing over the next 30 years.

    I am sure this post has touched all the internet users, its
    really really good article on building up new web site.

    Keadilan hanya akan berupa angin surga bagi sipenderita,
    dan menjadi topik populer dlm sinetron “Republik Mimpi”
    Kolaborasi antara penguasa dn pengusaha telah berhasil memutar balikan antara kebohongan dn kebenaran a.l.
    bencana alam vs kesalahan operasi, opini para pakar berkaliber internasional telah diabaikan, apalagi pendapat/kesaksian para pakar anak negri sdh dan tidak akan pernah didengan sama sekali; jual beli tanah (statement lapindo cs) vs ganti rugi (ref KEPPRES yg ditandatangani JK) setiap saat diteriakan oleh lapindo & BPLS. Kejadian lusi adalah ranahnya Drilling Eng. bukan ranahnya geologist, tetapi para teknokrat dlm lingkaran pemerintahan kupingnya hanya terbuka sebelah, hanya untuk ssuara yg mengatakan bencana alam tetapi tertutup untuk kesalahan operasi.
    Setumpuk uang sdh menjadi kiblat iman sekelompok orang/penguasa yg tega menukarkan kebenaran dengan kebohongan , moralnya lebih busuk dari pada seorang psk yg menggadaikan dirinya bagi sepiring nasi.
    A’uzubillahi minzalik.

    Coba Rakyat Indonesia sadar dan peka terhadap apa yang terjadi di Lapindo

    Dari awal sampe detik ini tidak ada unsur LSM / Lembaga Lain di Negeri Ku Indonesia ini yang Peduli Akan Nasip Lapindo
    Unsur DPR RI tidak ada anggapan apa apa kalau mau dibilang duit negara utk penyelesaiaan masalah Lapindo lebih bsar dari Century

    Kemana dan dimana tempat kali para Wakil Rakyat / LSM / NGO mana bantu dan perjuangkan Nasip Rakyat Kita

    Apa mungkin karna Lapindo ini adalah milik pengusaha probumi jadi anggota DPR RI dan semua Unsur diam karna sang pemilik ada salah satu tokoh dan pernah menjadi Menteri

    Seandainya Lapindo ini adalah pemiliknya bukan dari kalangan Elit mungkin pengusaha dan Kel yang bersangkutan sudah bulak balik di pangil lapindo didemo bahkan sudah dimasukan penjara serta assetnya di sita buta ganti korban Lapindo

    Dimana keadilan ini Bapak / Ibu DPR RI

    Coba Bapak Bapak sekalain berpikir dan melihat kenyataan ini……………………

    rakyat sekitar LAPINDO jadi korban dari ulah tangan manusia yang membuat kerusakan, dan keserakahan ! kalau pengeboran tsb berhasil yang menikmati hasilnya sebagian besar adalah orang tertentu, tapi kketika terjadi bencana rakyatlah yang merasakan,…FIRMAN ALLAH.” TELAH TERJADI KERUSAKAN DI DARATAN DAN DILAUTAN AKIBAT ULAH TANGAN MANUSIA”…..(sengaja maupun tidak sengaja)
