  2. Well logging - Wikipedia

    en.wikipedia.org/wiki/Well_logging

    The data itself is recorded either at surface (real-time mode), or in the hole (memory mode) to an electronic data format and then either a printed record or electronic presentation called a "well log" is provided to the client, along with an electronic copy of the raw data. Well logging operations can either be performed during the drilling ...

  4. Sonic logging - Wikipedia

    en.wikipedia.org/wiki/Sonic_logging

    The accuracy of modern compressional and shear sonic logs obtained with wireline logging tools is well known now to be within 2% for boreholes that are less than 14 inches in diameter and within 5% for larger boreholes. Some suggest that the fact that regular- and long-spaced log measurements often conflict means these logs are not accurate.

  5. Measurement while drilling - Wikipedia

    en.wikipedia.org/wiki/Measurement_while_drilling

    During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of drilling; to make detailed records (or well log) of the geologic formations penetrated by a borehole; to generate operations statistics and performance benchmarks such that ...

  7. Reservoir modeling - Wikipedia

    en.wikipedia.org/wiki/Reservoir_modeling

    This is required in order to find common ground between the well logs and seismic data. [3] Well logs are measured in depth and provide high resolution vertical data, but no insight into the inter-well space. Seismic are measured in time and provide great lateral detail but is quite limited in its vertical resolution. When correlated, well logs ...

  8. Log ASCII standard - Wikipedia

    en.wikipedia.org/wiki/Log_ASCII_Standard

    Log ASCII standard (LAS) is a standard file format common in the oil-and-gas and water well industries to store well log information. Well logging is used to investigate and characterize the subsurface stratigraphy in a well. A single LAS file can only contain data for one well, but it can contain any number datasets (called "curves") from that ...

  9. Formation evaluation gamma ray - Wikipedia

    en.wikipedia.org/wiki/Formation_evaluation_gamma_ray

    The formation evaluation gamma ray log is a record of the variation with depth of the natural radioactivity of earth materials in a wellbore. Measurement of natural emission of gamma rays in oil and gas wells are useful because shales and sandstones typically have different gamma ray levels.
