Do you know the theory of operation? Well, The prime mover rotates the pinion shaft via drive belt. The pinion shaft has mesh gear with crankshaft which transfer motion between them. The rotation of crankshaft causes angular movement of the three connecting rods in harmonic consecutive way. The connecting rods are pinned to something called […]

1- Model of BOP2- Bore (Internal Diameter)3- Working pressure: the maximum wellbore pressure, the ram can shut in and seal around.4- Temperature class: surface temperature the ram can withstand and have the same properties.5- Date of manufacture6- Rated control pressure: the hydraulic control pressure supplied to the ram from Accumulator unit. 7- Recommended operating pressure: […]

A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi (52,000 kPa)) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for […]

The safety system is installed under the roof as a means of shutting down the well in the event of an uncontrolled accident on the roof. These systems are classified into two main groups:1.Controlled subsurface safety valves from inside the well(Subsurface Controlled Subsurface Safety Valves – SSCSSV)2.Surface-controlled subsurface safety valves(Surface Controlled Subsurface Safety Valves – […]

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 […]
