As generally known, subsurface pressure can be implied using both wireline logs and drilling events. However, there may be a case where wireline logs and drilling events do not indicate the same subsurface pressure. Data from four vertical wells located i... see more

North Sulawesi has one large dam located in Pindol Village, Lolak District. The research objective was to determine the lithology of the bedrock of dam foundation, rock class, and subsurface permeability of the dam. The method used in this research is cor... see more

ABSTRACT A field monitoring of hydrological response and slope movement in an active landslide area, comprising of volcanic soil, was conducted to have a better understanding of the mechanism of landslide reactivation during a rainfall period. Monito... see more

Pore pressures of formations are one of the big problems facing the drillers in explorationareas. The pore pressure, together with fracture gradient, determines the amount of mudweight that is needed. Too much mud weight fractures the rock; too little mud... see more

On Earth, the deep subsurface biosphere of both the oceanic and the continental crust is well known for surviving harsh conditions and environments characterized by high temperatures, high pressures, extreme pHs, and the absence of sunlight. The microorga... see more

Numerous researchers have carried out studies on the mud volcano system in East Java. However, there have been no experiments on the mud volcano system's mechanism, including overpressure confirmed by direct subsurface data. Therefore, this study aims to ... see more

This research was conducted to study the factors leading to the uniform distribution of water from a subsurface irrigation system using porous tubes. The factors included the depth at which the tubes are installed, operating pressure, depth of impermeable... see more
