petrophysical การใช้

• The process begins with a detailed petrophysical analysis and well log calibration.
• Highly detailed petrophysical models are generated, ready for input to reservoir-flow simulation.
• The properties measured or computed fall into three broad categories : conventional petrophysical properties, rock mechanical properties, and ore quality.
• The calibration process replaces unreliable and missing sonic and density measurements with synthesized values from calibrated petrophysical and rock-physics models.
• The first step in seismic to simulation is establishing a relationship between petrophysical key rock properties and elastic properties of the rock.
• The BHA also provides directional survey, gamma, pressure, temperature, and in some cases, petrophysical logs as drilling progresses.
• Acoustic impedance is used to produce more accurate and detailed structural and petrophysical properties such as porosity, lithology, and fluid saturation.
• Geostatistical inversion simultaneously inverts for impedance and discrete properties types, and other petrophysical properties such as porosity can then be jointly cosimulated.
• Advanced real-time quantitative mineralogical and petrophysical analyses of cuttings and isotope logging help identify lithology for formation evaluation, geosteering, and well placement.
• When the petrophysical rock model is complete, a statistical database is created to describe the rock types and their known properties such as porosity and permeability.
• If volumetric calculations identify problems in the model, changes are made in the petrophysical model without causing the model to stray from the original input data.

• Techlog offers new functionality in each new release, not only in petrophysical and geological interpretation but also geomechanics interpretation, uncertainty and links to the industry standard platform like Petrel.
• Once well logs are properly conditioned and edited, a petrophysical rock model is generated that can be used to derive the effective elastic rock properties from fluid and mineral parameters as well as rock structure information.

• Wireline logging is performed by lowering a'logging tool'- or a string of one or more instruments-on the end of a wireline into an oil well ( or borehole ) and recording petrophysical properties using a variety of sensors.
• If the borehole has petrophysical measurements made of the wall rocks, and these measurements are repeated along the length of the core then the two data sets correlated, one will almost universally find that the depth " of record " for a particular piece of core differs between the two methods of measurement.
