Theory - Lab Report Example This is affected by electron intensity. If for example the intensity of the electrons is significantly high, there may be a lot of scattering which may produce a result which is far from what is expected. This is used to estimate the formation porosity and the formation density. Through the use of the litho-density the fluid type can also be established. The pore space of the oil and gas is also measured through the litho-density log. This refers to the amount of pores that are in a volume of a solid which is porous in nature. In this case, the value of the porosity is measured as a percentage. However, the true porosity includes the volume of the pores that are sealed. Clean formation is usually more than shales. As a result of this the bulk density will read less than the actual density. Therefore, the density porosity which is computed will be higher in terms of shales as compared to the actual porosity. The SP and GR log complement each other in the sense that Sp log uses electrical charge for the purpose of recording whereas the GR uses Gamma rays. Both of these measure different attributes which are existent in the well. These logs would not be advisable in situations where there is excessive radiation or electrical charge in the well. This is because these may cause fault in the equipment. They are, however, advocated in situations where the quantities of such attributes are average. The quality of caliper in this section will be low. This is because the porosity will take away a significant amount of materials from the region. The result of this is reduced quality of rock and
