Well logging
A well log is a record of one or more physical measurements as a function of depth in a borehole (From “Encyclopedic Dictionary of Applied Geophysics”). To measure the various values at once, one or more sondes comprise a tool string. Formation evaluation, lithological classification, and other geological interpretations are carried out from the logging curves or crossplots.Wireline Log and Logging While Drilling (LWD)
Wireline Logs are recorded by means of sondes carrying sensors which are lowered into the hole by a cable. Wireline Logs are done after drilling and tools are lowered into the borehole after removing drill pipes. Logging data are transmitted through wireline (cable) to the surface. LWD records bottomhole data acquired incrementally from sensors located inthe drill string near the bit in a drilling well. Recording LWD are during drilling. Data can be transmitted to the surface in real time by pressure pulses through the mud inside the drill pipe. Large data files (e.g. waveforms) are temporarily stored in the memory of the tool for later recovery.
Lithostratigraphy
Lithostratigraphy is the study of sedimentary layers based on physicalcharacteristics; or the study and correlation analysis of strata to reveal the sequences of stratigraphical history. Basic knowledge of each sequence lithology, the nature of well log responses, liquid and mineral contents, grain sizes, texture, color of rocks, physical attributes of rocks and other characteristics are required to study lithostratigraphy. The researcher who possesses complete knowledge ofregional lithology and sedimentology, and experiences the handling of logging data in detail is requested from this kind of investigation as lithostratigrapher.
Major focuses of the study include geochronology, comparative geology and petrology. Stratum information can be used to complement the core record, to fill gaps of record, and to indicate pinpoint boundaries. The basic unit oflithostratigraphy is the Formation: a mappable rock unit with distinct upper and lower boundaries. It will often represent a single depositional setting, and therefore a single rock-type or set of related facies. For example, the boundaries between beach sand, lagoonal mud, and carbonate bank depositional setting will migrate inland during a transgression. The lithostratigraphic boundaries are between eachenvironment (sandstone, shale, limestone), but the time boundary will cut across the lithological boundaries. After describing the sediment in each of the cores for a particular site, the next task is to define and categorize the sequence of sediment into particular lithostratigraphic units. NanTroSEIZE Shipboard lithostratigrapher is responsible to describe lithology and stratigraphy of sediments,sedimentary rocks. The researcher who experiences the handling of logging data in detail to the feature and strata of the deposit in Nankai Trough is also requested. They divide characteristical unit based on the feature of logging profile and the statistical procedure of logging data, and lithofacies of a basic rock, hemiperagic sediment, and the alternation of strata. It is also available toanalyse sedimentary facies and to recognize fault zone systems
Registro de pozo
Un registro de pozo es un registro de una o más medidas físicas en función de la profundidad en un pozo. La medición de varios valores a la vez, una o más sondas comprenden una sarta de herramientas. La evaluación de la Formación, clasificación litológica, y otras interpretaciones geológicas se llevan a cabo a partir delas curvas de registro o correlativos.
Registro línea de acero y registro durante la perforación (LWD)
Los registros con líneas de acero registran por medio de sondas que llevan sensores que se bajan en el agujero por un cable. Los registros de línea de acero se realizan después de la perforación y herramientas se bajan en el pozo después de retirar los tubos de perforación. El registro de datos...
