Drilling blamed for Java mud leakA mud leak that has displaced thousands of Indonesians was most probably caused
by drilling for gas, a scientific study into the disaster concludes.
The British-based scientists believe the drilling in East Java ruptured pressurised
limestone rock, allowing water and mud to rise to the surface.
They warn thousands of cubic metres of mud a day could continue to spew out for
months, if not years, to come.

casing to support the borehole, to protect against the pressure of fluids such as water,
oil or gas," team leader Richard Davies said.
"In the case of Lusi, a pressured limestone rock containing water - a water aquifer -
was drilled while the lower part of the borehole was exposed and not protected by casing.
