Stuck Pipe What is Stuck Pipe? Stuck pipe occurs when the drill pipe, drill string, or casing becomes immovable in the wellbore. This can prevent further progress in drilling, and if unresolved, it may require costly interventions or even abandonment … Continue reading →

Workover Operations Overview Before talking about workover operations it is important to remember the life cycle of a well, planning, drilling, completion, production, intervention, workover and abandonment. According to my experience the workover operations every day it becomes more important … Continue reading →

Sucker Rod Pump How Sucker Rod Pumps Work Sucker rod pumps operate using a reciprocating motion powered by a surface pumping unit. The key components include: 1. Pumpjack (Surface Unit): Converts rotary motion into vertical reciprocating motion. 2. Sucker Rod … Continue reading →

Rotary Drilling How Rotary Drilling Works Rotary drilling operates by continuously rotating a drill bit attached to a drill string, which penetrates the subsurface formations. A drilling rig provides the necessary power to rotate the bit, apply weight, and circulate … Continue reading →

Reservoir Fluid Properties Types of Reservoir Fluids Reservoir fluids are classified based on their composition, phase behavior, and physical properties. The primary types include: 1. Black Oil – A high-viscosity crude oil with dissolved gas that separates under lower pressures. … Continue reading →

Gas Reservoirs Types of Gas Reservoirs 1. Dry Gas Reservoirs Contain primarily methane (CH₄) with little or no liquid hydrocarbons. Produce only natural gas at surface conditions. Typically have high recovery factors due to efficient gas expansion. 2. Wet Gas … Continue reading →

Drilling Rig Components Diesel Engines – Supply mechanical or electrical power. Generators – Convert mechanical energy into electrical power. Electrical Control System – Distributes power to various rig components. Derrick or Mast – A tall steel structure that supports the … Continue reading →

Wireline Operations Types of Wireline Operations Wireline logging is one of the most common wireline operations. It involves lowering a series of measurement tools into the wellbore to gather data about the geological formations and fluid characteristics. Types of Wireline … Continue reading →

Drilling Operations Types of Drilling Operations Conducted to identify and evaluate potential hydrocarbon reservoirs. Typically involves drilling wildcat wells in unexplored areas. Drilled in known reservoirs to maximize hydrocarbon recovery. Focuses on optimizing well placement for efficient production. Aims to … Continue reading →
