The test nobody wants to fail, but everybody must pass. Before that coiled tubing string goes anywhere near a live wellbore, we ask one very important question: If everything goes wrong, can this thing actually cut the pipe and hold pressure?That’s the shear test. The shear seal rams on a CT BOP aren’t just for […]

A panel where operator control back pressure applied on a closed well to keep the well under control (Keep Bottom hole pressure constant).It has many components as shown in the picture: 1- Control lever: choke on the well using hydraulic choke (need air supply to function)2- Choke position indicator: indicates choke opening %.3- Pressure gauges: […]

Since drilling is the process of cutting rock by chipping or crushing, vibrations are almost unavoidable during drilling operations. Downhole vibration is typically measured and monitored using sensors placed within the drilling assembly and is commonly reported as root-mean-square acceleration to help field technicians analyze subsurface conditions and drilling performance. Downhole #vibration generally occurs in […]

A Measurement While Drilling (MWD) system is a critical downhole tool used in oil, gas, and geothermal drilling. Integrated directly into the drill string, it collects real-time directional and drilling mechanics data. Such as inclination, azimuth, and temperature—allowing engineers on the surface to accurately steer and adjust the wellbore path Key Functions & Sensors An […]

Overview The three-phase separator is a critical piece of equipment for handling mixtures of oil, water, and gas, widely used in oil and gas production facilities. To ensure the safe and stable operation of the equipment, meticulous preparation must be conducted before commissioning, and the startup process must follow standard operating procedures which includes pre-operation preparation, startup […]

What is Derrickman’s work?

In the oil and gas industry, slips are essential mechanical devices used to grip and suspend the drill string in the rotary table on the drill floor. They prevent the heavy pipe from falling down into the wellbore when it is disconnected from the hoist. Think of them as a “wedge-lock” system: the more weight […]

In Coiled Tubing (CT) operations, maintaining well control while working under pressure is critical. Two key components make this possible: Stripper and BOP (Blowout Preventer) which called PCE( pressure control equipment) 1. The Stripper (primary barrier) The Stripper is the primary sealing element during normal operations. How it works:• Uses a rubber element to seal […]

In liquid nitrogen (LN₂) storage tanks, maintaining a stable internal pressure is essential for safe and reliable operation.The pressure build-up vaporizer (PBU vaporizer) is a dedicated component designed specifically to increase and regulate the tank pressure, not to supply nitrogen directly to downstream processes. Liquid nitrogen is stored at extremely low temperature (approximately –196°C) and […]
