Dogleg

Doglegs are changes in well angle or direction from a predetermined path, usually measured in degrees per 30 m. In directional drilling, the well angle constantly deviates from the vertical axis. A dogleg refers to…

Geothermal Energy

Geothermal energy uses heat of earth as a source of renewable energy. It is generally used to create electricity. Heat from the earth’s crust warms fluid that seeps between underground rocks. This fluid will form…

Geothermal

Geothermal is a renewable energy that utilize the heat from the earth. Since the core of the earth has a high temperature (estimated 5500 0C), it is not surprisingly if upon the core earth still…

Drilling Fluids Life Cycle

DRILLING FLUIDS LIFE CYCLE The annulus degraded by downhole conditions, dehydrated and loaded with formations solids which caused mud returns up to the surfaceAt the surface, the mud flows down from the flowline to the…

Circulation

In the process of oil drilling, there is a process called circulation where ‘drilling mud’ or ‘drilling fluid’ is pumped through the bit into the well, carrying cuttings back to the surface. Source : https://www.croftsystems.net/oil-gas-blog/what-is-drilling-mud…

Pumpjack (How Does It Work?)

In a nutshell, Pumpjack works using up and down movement from the synergy of all the main parts. The movement will create an artificial pressure like a straw and forcing oil out of the well.…

Pump Jack

Pump jack is a device used in oil extraction when the pressure inside a well is not sufficient to force oil up to the surface. Pump jacks create a process called “artificial lift” by adding…

Types of Rigs

A (drilling) rig is simply put, a structure that has heavy equipment and houses necessary facilities for drilling activities at a well. Every rig has 5 main systems to operate, which are: Power Generation system:…
