oa Exploring for High Pressure and High Temperature (HPHT)<br>Hydrocarbon Pools: Technology Challenges Versus Pessimism - Guling Deep-1 Experience

Shallow and easy hydrocarbon accumulations are “almost extinct species”. Previously in Malay Basin, not many wells were drilled into and beyond the overpressured formation. The central part of Malay Basin still has untested high pressure and high temperature zones. Deep and overpressured formations will be among the next interesting exploration focus. Current technological developments compliment the drillability of such targets. Persistent general lack of serious commitment hindered the exploratory works. Last year PETRONAS (PMU) tested overpressured reservoirs at Guling Deep-1 location within budgeted time and AFE. The result surpassed pre-drill expectations and proved working petroleum system in the overpressured zones.
