اسلاید ۸: LOG INTERPRETATION OBJECTIVESThe objective of log interpretation depends very much on the user. Quantitative analysis of well logs provides the analyst with values for a variety of primary parameters, such as:porositywater saturation, fluid type (oil/gas/water)lithologypermeabilityFrom these, many corollary parameters can be derived by integration (and other means) to arrive at values for:hydrocarbons-in-placereserves (the recoverable fraction of hydrocarbons in-place)mapping reservoir parametersBut not all users of wireline logs have quantitative analysis as their objective. Many of them are more concerned with the geological and geophysical aspects. These users are interested in interpretation for:well-to-well correlationfacies analysisregional structural and sedimentary history In quantitative log analysis, the objective is to definethe type of reservoir (lithology)its storage capacity (porosity)its hydrocarbon type and content (saturation)its producibility (permeability)

اسلاید ۹: GAMMA RAY LOGGamma Rays are high-energy electromagnetic waves which are emitted by atomic nuclei as a form of radiationGamma ray log is 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.Correlation between wells,Determination of bed boundaries,Evaluation of shale content within a formation,Mineral analysis,Depth control for log tie-ins, side-wall coring, or perforating.Particularly useful for defining shale beds when the sp is featurelessGR log can be run in both open and cased hole

اسلاید ۱۰: Spontaneous Potential Log (SP)The spontaneous potential (SP) curve records the naturally occurring electrical potential (voltage) produced by the interaction of formation connate water, conductive drilling fluid, and shale The SP curve reflects a difference in the electrical potential between a movable electrode in the borehole and a fixed reference electrode at the surface Though the SP is used primarily as a lithology indicator and as a correlation tool, it has other uses as well:permeability indicator,shale volume indicator porosity indicator, andmeasurement of Rw (hence formation water salinity).

اسلاید ۱۱: Neutron LoggingThe Neutron Log is primarily used to evaluate formation porosity, but the fact that it is really just a hydrogen detector should always be kept in mind It is used to detect gas in certain situations, exploiting the lower hydrogen density, or hydrogen index The Neutron Log can be summarized as the continuous measurement of the i
