They are tools commonly used in the Oil and Gas industry which assist in finding downhole reserves. They will be located near the bottom of the drill string and typically close to the drill bit. Information from these tools is either sent up the mud column via mudpulse telemetry or saved in the tool's storage to be analyzed once the tools are pulled from the hole. Lithology and porosity are defined in oilfield and geology dictionaries.
lithology is a myth (there is the answer)
A value for porosity can alternatively be calculated from the bulk density ρbulk and particle density ρparticle: Normal particle density is assumed to be approximately 2.65 g/cm3, although a better estimation can be obtained by examining the lithology of the particles.
A borehole geophysical log is the science of recording and analysing measurements of physical properties made in wells or test holes. Borehole Geophysical logs provide a borehole record of the lithology, fractures, permeability, porosity and water quality.

big particles=low porosity small particles=high porosity
A geological reservoir is a subsurface rock formation that holds significant amounts of natural resources such as oil, natural gas, or water. These reservoirs have the capability to store and release these resources over time, making them crucial for energy production and water supply. The characteristics of the reservoir, such as porosity and permeability, determine how easily these resources can be extracted.
Lithology is the branch of geology that deals with the physical characteristics of rocks, such as their mineral composition, grain size, texture, and structure. It focuses on describing and classifying rocks based on their observable features and properties. By studying lithology, geologists can better understand the processes that have shaped the Earth's crust and the environments in which rocks were formed.
A stratum.
how do we calculate porosity of ceramic?
Porosity is the formation of bubbles in the weld.
poorly sorted = low porosity well sorted = high porosity
The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
