Open-hole (Wireline) logging is one of a very huge range of measurements and analytic proficiencies employed in formation evaluation of oil wells.

Wireline logging provides the outstanding meeting place for all formation evaluation methods in oil wells. Only through open-hole logging may a continuous record of measurement versus depth be made of so a lot of formation properties. In particular, wireline logs may record formation electrical resistivity, bulk density, natural and induced radioactivity, hydrogen content, and elastic modulae. These raw measurements may then be interpreted to give a ceaseless measurement -versus-depth record of formation properties such as porosity, water saturation, and rock type. Almost without exception, each well drilled for hydrocarbons (oil and gas) is logged with wireline instruments.

With the price of oil at such a high right now, more and more oil operating companies are gearing up for more drilling, and hence more wireline logging, to maximize their profits at this time of high oil prices.

The actual running of a log involves letting down a tool at the end of a logging cable into an oil/gas well. A sensor, integrated in a sonde together with it is affiliated electronics, is suspended in the hole (well) by a multiconductor cable. The signals from the sensor are conditioned by the downhole electronics for transmission up the cable to the control panel at surface which in turn conditions the signal for the recorder. As the cable is raised or lowered, it activates a great deal of depth-measuring device, a sheave wheel (pulley) which in turn activates a recording device. Finally, a good deal of form of reproduction takes place to provide a hard copy of the recorded info which is called the well log.

In general, wireline logging jargon distinguishes amongst a logging survey/run, a logging tool, and a log as well as a curve. There is oftentimes a great deal of confusedness when it comes to these terms when logging matters are discussed. A logging survey is provided by a logging service company for a client. During the course of the logging pass/survey, the logging engineer may utilize various logging tools, and record assorted dissimilar logs on each of which are staged various dissimilar curves. The logging tools used, in turn may be composed of multiple sensors.
