INILAH.COM, Jakarta Some experts conclude Lapindo mud eruption was not due to human error. Nor does the procedure does not deserve exploration. Cause, so due dilligence two studies, because of natural factors: earthquake!
Theory Richard Davies, Durham University geologist, England, about the Lapindo mudflow, irrefutable. Davies believes the mud caused by the procedure before exploration activities are not eligible. He assess gas drilling the Banjar Panji-1 did not meet eligibility requirements.Many people make the research as a foundation Davies thinks and acts. Lapindo almost cornered. In fact, the eruption of mud, according to most research scientists from various countries, due to the earthquake that had struck Yogyakarta and its surroundings.
The conclusion was revealed in two recent reports described in the scientific community events geologist in Cape Town, South Africa. They concluded that the eruption was not triggered Sidoarjo mud drilling.
The first report is based on due diligence study on the drilling process. In a report entitled Observations on Event Planning Banjar Panji-1 and Reason Drilling Program, revealed many things. Among others about the proper planning of drilling operations in order to maintain industrial procedures. Planning is also done with high standards to maintain the safety of the crew.
"The earthquake and aftershocks in Yogyakarta and its aftermath is the key cause of the incident," the caesura in the report.
This report was written two leading petroleum engineers. They are Maurice Dusseault PhD from the University of Waterloo, Canada and Baldeo Singh, S3 engineers from the Massachusetts Institute of Technology, USA.
Sidoarjo mud eruption began on May 29, 2006. The incident occurred after a magnitude 6.3 earthquake on the Richter scale attack Yogyakarta and surrounding areas. A mud volcano started erupting from the long cracks at a distance of 200 km from the center of the earthquake.
Since then, 150,000 m3 of mud keep coming out every day, inundating nearby villages and cause damage to local infrastructure. According to experts, the mud flow can be sustained until the time seemed long.
The second report due diligence proffered Ralph Adams, a Canadian engineer who has 29 years experience in oil and gas drilling in Indonesia. Adams wrote the report Banjar Panji-1 Well Control Incident Report.
"The program changes in order to well drilling and drilling is not the cause of the eruption. (Shot) is opened by a huge earthquake less than 24 hours before the subject wells," he wrote.
Two results of this study strengthen the study of the geological team of Norway, France, and Russia, which concluded the Yogyakarta earthquake as the cause of the eruption of mud Sidoardjo. A team led volkanolog mud, Dr. Adriano Mazzini from the University of Oslo, has reported the matter in Earth and Planetary Science Letters, on July 12, 2007.
"This shows that the distribution of earthquakes repeatedly pressure in some parts of Java island," wrote Dr. Mazzini in his report. In some places that can aggravate the fractions on previous mistakes, causing the air pressure becomes moist. So absorbing and producing eruptions through many processes in the subsurface soil.
Initially, the opinion of Davies could generate huge attention from the media. Beberepa NGOs use them to attack the company's joint-venture exploration Indonesia-Australia, the Lapindo Brantas Inc.. Lapindo successfully defend himself in court when the demand by a local NGO. Because of these NGOs failed to provide evidence that shows the errors of Lapindo. [I4]
