To accurately evaluate altered volcanic reservoirs in the Songliao Basin of China and study
the effect of alteration on pore structure, this paper established a methodology for log …

Shales in the reservoir causes complications for the petrophysicist because they generally
are conductive and mask the high resistance characteristic of hydrocarbons. Data from a …

Well water quality has been characterized with constant and continuous changes via the
interaction of rock, soil and natural nano-filters which terminates at the aquiferous layer for …

Understanding the factors affecting reservoir quality and producing wells requires an in-
depth knowledge of petrophysical analysis. The study employed wireline log data from three …

Sumur AP# 1 berada pada Formasi W di lapangan lirik dan telah diproduksikan sejak tahun
1975. Seiring berjalannya waktu, produksi minyak sumur AP# 1 yang berada pada lapisan …

Abstract Evaluation of shaly-sand reservoir units in an onshore field Niger Delta was
undertaken. The study aim is to optimize recoverable hydrocarbon volumes/water saturation …

The purpose of this paper is to study the strength of rocks by determining their Unconfined
Compressive Strength (UCS), correlate the determined strength to physical properties of …

Comprehensive comparative analyses of 18 shaly sandstone zones in four wells of an Oil
Field in the Niger Delta were carried using only the Archie Model with the appropriate …
