One of the most satisfying parts of rig maintenance is finding the real root cause instead of replacing parts based on assumptions. In this case, the High Clutch failed to engage, accompanied by a loud air leak. The initial suspicion was a damaged diaphragm, so the clutch assembly and ELMAGCO brake coupling were disassembled for […]

A hydraulic oil leak caused the HPU reservoir on a NOV 1625 UDBE Drawworks to lose oil, requiring a complete inspection of the Service Brake system. In this maintenance job, we: www.goscoenergy.com Contact Us

In this video, a rolling bearing is rotated by hand to demonstrate one of the most fundamental and practical methods for early bearing failure detection. A healthy bearing should rotate smoothly, quietly, and without any noticeable vibration. The presence of a grinding or scratching noise is a strong indicator of internal damage and increased friction […]

One of my most valuable and educational experiences was disassembling Caterpillar diesel engine air starters. These air motors are Ingersoll Rand SS815R models. Taking a close look at this equipment and its manufacturing details is truly enjoyable and instructive. At the beginning of the job, based on experience, we paid close attention to the direction […]

Dough Method is a technique used for removing chips and debris from gears and internal components of machinery. By using a dough-like or sticky compound, it collects metallic and non-metallic particles left behind after operation or repair. Due to its ability to penetrate grooves and complex spaces, this method can remove even particles that are […]

Agitators play a critical role in drilling operations by homogenizing and uniformly mixing drilling fluids. Through controlled rotational flow, they prevent the settling of clay, weighting materials, and solids, while maintaining the rheological properties of the mud within optimal parameters. This is essential for maintaining wellbore pressure, preventing bridging, reducing pump circulation issues, and improving […]

CROSSHEAD LINERS – The crosshead liners are bolted into the main frame. Special sealing washers are used · under the heads of the bottom capscrews to seal and prevent oil leakage. Install the liners in the frame without shims, and tighten securely. Use micrometers and measure the inside diameter between the upper and lower liners […]

When discussing drilling safety, one piece of equipment stands above the rest: the Blowout Preventer (BOP). Installed on top of the wellhead, the BOP is a high-pressure safety system designed to prevent the uncontrolled release of oil, gas, or drilling fluids an event known as a blowout. Why is a BOP needed? As a well […]
