This paper evaluated the oil and gas potential of Cretaceous Yageliemu clastic reservoir within Yakela condensed field lying in Kuqa Depression, Tarim Basin, China. The petrophysical properties interest zones area were characterized using geophysical logs from five wells. results reveal that gas-bearing are by high resistivity, good permeability (K) effective porosity (?eff), low water saturati...

NMR is a popular logging technique used to estimate pore size information, formation permeability, wettability and irreducible water saturation. Quantitative interpretation of NMR data is based on a set of fundamental assumptions (e.g., pore isolation and fast diffusion). These assumptions establish the quantitative link between NMR response and petrophysical predictions. While there is a need ...

[1] Geophysical imaging has traditionally provided qualitative information about geologic structure; however, there is increasing interest in using petrophysical models to convert tomograms to quantitative estimates of hydrogeologic, mechanical, or geochemical parameters of interest (e.g., permeability, porosity, water content, and salinity). Unfortunately, petrophysical estimation based on tom...

Biyad Formation is mainly made up of clastic sediments that contain substantial amount of proven crude oil in the eastern Yemen. The Byiad clastic is divided into Upper and Lower Biyad clastic units. Several vertical wells have been drilled and penetrated this formation. This study is concerned with the petrophysical evaluation by means of well log data of the Lower Cretaceous rocks at the East...

[1] We have investigated the potential of combining cross-hole georadar velocity and attenuation tomography as a method for characterizing heterogeneous alluvial aquifers. A multivariate statistical technique, known as k-means cluster analysis, is used to correlate and integrate information contained in velocity and attenuation tomograms. Cluster analysis allows us to identify objectively the m...

Abstract Understanding basic petrophysical properties may enhance the recovery of residual oil saturation and help in reservoir management. Reservoir is fraction porosity a zone occupied by oil. The trapping increase with porosity. Oil reservoirs represent significant world-wide. We try to make evaluation using analysis well logs core samples at Issaran Field, South Gharib Formation, West Gulf ...

This work represents study the rock facies and flow unit classification for Mishrif carbonate reservoir in Buzurgan oil Field, which located n south eastern Iraq, using wire line logs, core samples petrophysical data (log porosity permeability). Hydraulic units were identified zone indicator approach assessed within each type to reach better understanding of controlling role pore types geometry...

A considerable effort has been made in the literature for quality assurance (QA) and checking (QC) of petrophysical log data computation reservoir rock property parameters. Well plays an integral role building a physics model quantitative interpretation (QI) work. poor-quality may lead to significant financial HSSE implications by drilling wells undesired locations. Historically, variety techni...
