Description:
The Aminoil Group drilled a 10,000 ft - well a few kilometers off the Krakatau volcano in 1973. The well bottomed in Pliocene sediments after penetrating a more than 8,000 ft thick Upper Pliocene section of mainly claystones with interbedded sand-, siltstones and pyroclastics. On the basis of temperature surveys and BHT's measured during logging, a static formation temperature in excess of 450° F was extrapolated for the bottom of the hole. Tue high temperatures caused some deterioration in the mud properties, but otherwise no serious drilling problems. Owing to overpressures a high salinity oil mud and controlled drilling had to be employed. The well was P&A because no economic hydrocarbon accumulations could be expected in the high temperature regimes.
