What is the resistance protocol?

The resistance protocol is a data collection system used to assess the electrical potential in the rocks. Since different types of rocks have different electrical conductivity, resistance protocols can provide information on different compositions of rock formations buried under the surface. These protocols are often used by the oil industry to find natural oil tanks by a process called formation.

The resistance is expressed in ohms or ohms/meter. It is often expressed on a logarithmic scale, because each study area usually has a number of resistance. The amount of current registered is also dependent on the studied area. Larger areas will have less dense currents, so the density of the recorded current is divided by the tested area to determine the ohm/meter measurement. Since the electric current cannot penetrate far into the ground, the drills are drilled to help the formations below the surface.

Two different types of devices Used to obtain resistance protocols areLaters and induction coils. Laterologists rely on the information obtained by electrodes that send electric current to the rock located in various positions along the well. Induction coils rely on magnetic fields produced by coils and less frequently used to assess the formation.

Several factors contribute to the electrical conductivity of rocks. Porosity and salinity increase electrical conductivity. On the contrary, the non -cut rocks and areas mostly of clay reduce it. Oil and gas have a high resistance and can read 50-500 ohms on the resistance protocol, while the water will only have a 1-10 ohms reading. The protocols themselves look similar to the values ​​of seismograph or lie detector - a number of twisting lines in the length of paper.

In oil drilling, oil geologist studies resistance and other protocols to see if this is likely that the amount of oil found near New Wells is worth further drilling. Once the drill isDrill, oil geologists will be called to analyze the amount of oil present nearby. However, these geologists look at more than just a protocol of resistance, because insecure rocks and salt water have high resistance, but no oil. Other protocols such as gamma protocols and observation protocols are also examined during the process.

In scientific studies, resistance is also used to discover more about Earth's geology. In lithostratigraphy, the study of the Earth layer, scientists use resistance to obtain information about the earth's layers. By studying the composition of rocks formed for millennia, the scientist can conclude the conclusions of the history and development of the country.
