Wireline logging services offer detailed information on the downhole’s physical condition. Operators use different tools and techniques to measure the size, shape, and fluid flow in the reservoir. It offers complete detail of the downhole’s physical properties with a clear photo on a computer screen. Also, it gives information on flow rate, residual oil saturation, and fluid type. An electric cable or slickline is used t lower down the wireline tools into the well from the surface. The operation can be performed by reputable companies like Renegade Wireline Services. This post talks about the different kinds of wireline logging equipment and tools that can be used to complete well evaluation. These pieces of equipment and tools include the following:

Density Logging Tools

These tools are used for measuring the rock bulk density along the wellbore’s walls. With these tools, a radioactive source emits the gamma rays in the wellbore that get colloid with electrons present in formations.

Neutron Logging Tools

In these tools, a radioactive element is used to emit neutrons in the well formation. The neutrons will spread into nuclei and lose energy. As the high energy neutron interacts with the nuclei of atoms in the formation, it gets converted into the thermal particle. Then, the wellbore’s hydrogen and chlorine molecules will absorb the thermal neutrons, allowing operators to measure the presence of hydrogen in the formations or reservoir fluid.

Acoustic Logging Tools

These tools are composed of a transmitter, receiver, and accompanying electronics. The sound wave they generate travels from the transmitter to rock formations in the wellbore. As the sound wave moves through rocks, a lot of kinds of waves are generated that reflect the receiver. The receiver analyzes the wave amplitude with time and offers the result associated with downhole porosity.

Resistivity Log Tools

These tools measure the resistivity through casing and cement of reservoir. The inject current in the well and flow in an upward and downward direction. The majority of the current remain inside the casing while some of it escapes to the formations. The tools’ electrodes measure the possible difference because of the leak current. Measuring the resistivity helps in determining the oil residue in the wellbore and offers information on hydrocarbons that wellbore contains.

Providers of cased-hole logging services can offer important information on oil and gas exploration and exploitation. It is important to purchase the best equipment and recruit a professional to perform the accurate oil well measurement to ensure great productivity.
