Lockdown screws, (LDS) utilize an external thread (ET) design that moves the threads outside the pressurized or wetted surface of the wellhead equipment. They utilize a robust Unified National Coarse (UNC) thread for the lockdown screw itself and the packing gland nut to minimize any galling. Additionally a one piece HBNR compression packing element with […]

BOP Testing Procedures
Use water to test BOP’s. The reason is that water has less compressibility than mud. Make up testing assembly and set in into a wellhead profile. Ensure that the casing valve must be left opened and there must be personnel monitoring the outlet of casing valve all time while testing. You must ensure that personnel […]
Blowout Preventer (BOP)
BOP is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves. Blowout preventer were developed to cope with extreme erratic pressures and uncontrolled […]
Stuffing Box Leaking
Purpose of a Stuffing Box:A stuffing box is used to maintain or seal the pressure of fluid during unit operation. The pumping unit moves around the rod to pull whatever you are trying to access — such as oil — to the surface. The stuffing box helps maintain the correct pressure inside the unit during […]
The Wellhead and Christmas
The wellhead and Christmas tree are essential components of an oil or gas that help control the flow of fluids and ensure safe and efficient operation. Here are the main components of ahead and Christmas tree; Wellhead: 1. Casing head: The casing head is the first component of the wellhead and serves as the interface […]
Blowout Prevention (BOP)
What is a Blowout? A blowout occurs when formation pressure exceeds the pressure control measures of a well, causing an uncontrolled flow of hydrocarbons to the surface. This can lead to fire, explosions, and environmental disasters. The most infamous blowout in history is the Deepwater Horizon disaster in 2010, which resulted in significant oil spills […]
Choke and Kill Equipment
Choke and Kill Equipment – Ensuring Well Control and Safety Choke and kill equipment plays a critical role in well control operations, helping to manage pressure, prevent blowouts, and ensure safe drilling activities. These systems are essential for handling unexpected well kicks and maintaining operational integrity. Key Insights from the Document: ✅ Choke and Kill […]
CHRISTMAS TREE EQUIPMENT
A Christmas Tree is an assembly of valves, spools, and fittings used for an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well, and other types of wells. It is named for its resemblance to a decorate tree at Christmas. Many times, the words Christmas Tree and Wellhead are […]
What is a BOP?
A Blowout Preventer (BOP) is an important piece of equipment used in well operations in the oil and gas industry to prevent uncontrolled releases of crude oil or natural gas from the wellbore. BOPs ensure that pressure control is maintained during drilling, well completion and well intervention operations.Basically, the main function of a BOP is […]
Shear Ram In Blowout Preventer (BOP)
Shearing a drill pipe using the shear ram in a blowout preventer (BOP) is a safety-critical procedure performed in emergency situations during drilling operations. The primary reasons for shearing are: If the well becomes uncontrollable, the shear ram cuts the drill pipe and seals the wellbore to prevent hydrocarbons from escaping. This action helps avoid […]
