Petrophysical Characterization Of Sandstone Reservoir From Well Log Well log data free download as pdf file (.pdf), text file (.txt) or read online for free. the document provides information about two wells, ctw1 and ctw1 2, including their locations, scales, lithology logs, and descriptions of the rock formations encountered. 1600 1800 2000 — a sandstone reservoir, indicated by low gamma ray, rhob nphi cross over, and high resistivity value. this is an oil reservoir (nphi not too low).
Well Log Data Pdf Shale Sandstone The problem of shale contamination is particularly important in the reservoir evaluation of shaly sandstones, and its neglect can lead to significant errors in both porosity and hydrocarbon saturation evaluations. the responses of the logging tools that have been reviewed are affected to some degree by the proportion of the shale and, to a lesser extent, its distribution. The results of the petrophysical analysis were presented in bi plots and log vs depth format (log tracks) for convenient interpretation. Draw in the log as a schematic representation of the total gamma ray that you might expect from each of the 100% shale and clean sandstone lithologies. assume that all 100% shales have the same gr value, which is 120 api. Detailed stratigraphic interpretation of borehole electrical images includes the classification of different bedding types, such as sand (sandstone) bedding or shale bedding. successful interpretation depends on accurately determining the sandstone shale boundary.

K 1 and k 3 well log data on js field, west natuna basin, riau islands. main focus of the research is types of lithology indicated by response the petrophysical well data log of lower middle miocene arang formation. arang formation was deposited immediately on top barat formation and de. A toc detection method based on log data has been attempted in the wells in order to illustrate the potential variation of organic carbon (or organic matter volume) present in the formation intervals along the wells. Gamma ray log is a measurement of natural radioactivity in formation verses depth. it measures the radiation emitting from naturally occurring u, th, and k. it is also known as shale log. gr log reflects shale or clay content. clean formations have low radioactivity level. Actual well logs from south texas and north sea fields are used to investigate and compare the five water saturation models in shaly sand reservoirs. the well logging derived data are used to calculate water saturation, identify shale distribution and perform sensitivity analysis for different models.
