Spontaneous Potential Log

Untitled

Main objective of this lecture is to present on Spontaneous Potential Log. The spontaneous potential (SP) curve records the naturally occurring electrical potential (voltage) produced by the interaction of formation connate water, conductive drilling fluid, and shale. The SP curve reflects a d.....

Presentation on Air Masses

Air Masses

Prime purpose of this lecture is to present on Air Masses. Air Masses are a large body of air that has properties similar to the part of the Earth’s surface over which it develops. It is a body of air with horizontally uniform levels of temperature, humidity, and pressure. it is an extreme.....

Cloud Formation

cloud formation

Basic purpose of this lecture is to present on Cloud Formation. Masses of small water droplets or tiny ice crystals that float in the air. Three main types are cirrus, cumulus, and stratus. Other clouds are a mixture of these three main types. Clouds are formed when air containing water vapo.....

Presentation on Weather

Weather

General purpose of this lecture is to present on Weather. Weather refers to the state of the atmosphere at a specific time and place. The one thing that you can talk to anybody about. If you don’t like the weather just wait around it will change in Texas. This lecture briefly describe what .....

Acoustic Log

acoustic log

Principle objective of this lecture is to present on Acoustic Log. Acoustic tools measure the speed of sound waves in subsurface formations. While the acoustic log can be used to determine porosity in consolidated formations, it is also valuable in other applications, such as: Indicating litho.....

Resistivity Log

resistivity log

Major objective of this lecture is to present on Resistivity Log. Resistivity logging is a method of well logging that works by characterizing the rock or sediment in a borehole by measuring its electrical resistivity. Here briefly describe on basics about the Resistivity: it measures the ele.....

Neutron Logging

neutron logging

The Neutron Log is primarily used to evaluate formation porosity, but the fact that it is really just a hydrogen detector should always be kept in mind. It is used to detect gas in certain situations, exploiting the lower hydrogen density, or hydrogen index. The Neutron Log can be summarized as .....

The Density Log

The Density Log

The aim of this lecture is to present on the Density Log. The formation density log is a porosity log that measures electron density of a formation. Dense formations absorb many gamma rays, while low-density formations absorb fewer. Thus, high-count rates at the detectors indicate low-density f.....

Gamma Ray Log

gamma ray log

Gamma Rays are high-energy electromagnetic waves which are emitted by atomic nuclei as a form of radiation. Gamma ray log is measurement of natural radioactivity in formation verses depth. It measures the radiation emitting from naturally occurring U, Th, and K. It is also known as shale log. .....

What is Well Logging?

well Logging

Prime objective of this lecture is to present on what is Well Logging. Well logging chronicles the depths, subsurface formations and events encountered while drilling. Well logs can include visual observations or be made by instruments lowered into the well during drilling. Well log is a contin.....

Presentation on the Work of Rivers

Work of Rivers

Basic objective of this lecture is to present on Work of Rivers. The erosional work of streams/rivers carves and shapes the landscape through which they flow. Three functions of rivers; Erosion; Transportation and Deposition.. The energy in a river causes erosion. The bed and banks can be e.....

Lecture on the Appalachian Trail

Appalachian Trail

The Appalachian Trail is a continuous marked footpath that goes from Katahdin in Maine to Springer Mountain in Georgia, a distance of about 2160 miles. Here explain Appalachian Trail with mathematical examples; like: If you walked 10 miles a day, how many days would it take you to complete the .....
