This article will describe the initial pressure testing requirements for surface Blowout Preventer (BOP) stack components as outlined in standardized regulatory guidance. The specifications differentiate between low-pressure and high-pressure testing thresholds and incorporate operational conditions such as component replacement, elastomer changes, and system integrity considerations. The intent of these requirements is to ensure functional reliability, containment assurance, and conformity with well control safety practices.

Shale shakers area vibrating machines used on drilling rigs to separate solid rock cuttings from the drilling fluid (or “mud”) so the cleaned fluid can be reused in the drilling process. When drilling, rock cuttings mix with this mud and must be separated before the fluid can be reused. The first and most important step in this solids control process is done by a machine called the shale shaker. Though it may look simple, the shale shaker plays a major role in keeping drilling operations efficient, safe, and cost-effective.

When we see the oil production facility flare gas, we often misunderstand it as waste. However, this flame represents a critical safety and operational practice known as flaring. Far from being an environmental oversight, flaring is fundamental to the safe, efficient, and compliant operation of complex industrial facilities. Let’s explore why flaring is not just necessary, but an indispensable part of the oil and gas industry.

The wash pipe is a cylindrical component positioned within the top drive or swivel of a drilling rig. Its primary function is to form a high-pressure seal between the rotating drill string and the stationary housing of the top drive system. Without this component, maintaining fluid containment and rotational integrity would be nearly impossible.

The travelling block on a drilling rig is a big, heavy-duty pulley system that moves up and down the rig’s derrick (the tall tower structure). It’s part of the hoisting system, and it’s responsible for lifting and lowering all the heavy stuff—like the drill string, drill pipe, casing, and downhole tools—into and out of the well. Its functions are as follows;
