Abstract

This paper is a part of palynological investigationon The Eocene Nanggulan Formation, Yogjakarta Central Java. The Nanggulan Formation containing rich palynomorph assemblage provider excellent data to support sequence stratigraphy analysis. The palynomorph assemblage changes (especially between mangrove and freshwater palynomorphs) may reflect sea level changes whitch can be used to interpret system tracts, which are the internal building blocks of sequences.
ESTIMATING POROSITY AND WATER SATURATION FROM SEISMIC/ACOUSTIC SIGNALS: A CORRECTION ON THE EFFECT OF SHALINESS Bambang Widarsono; Fakhriyadi Saptono

Abstract

The presence of shale in sedimentary rocks tends to introduce complexity in any formation evaluation activities. This is also the case when efforts are spent in estabilishing a method that enables analysts to estimate porosity and water saturation from seismic survey.

Abstract

Computerized tomography (CT) is a new radiological imaging technique that measures density and otomic composition inside object. Since 1980, the CT has been applied in petrophysics and reservoir engineering. This paper discusess several petrophysica application in core analysis such as: quantification of complex mineralogy, characterixation drilling fluid invasion core quality control bedding detection, porosity determination, and fracture analysis.

Abstract

Chemical dispersants are often used to disperse spilled oils, which threaten to pollute shoreline areas. In Indonesia all dispersants produced or marketed should undergo the toxicity test with regand to certain types of fish to determine the threshold limit, LC-50. The type of surface-active agent (surfactants) and the solvent used in the dispersants, which determine the dispersing quality, might be toxic to the marine species and bacteria.
