What is a pulsation dampener in a mud pump?

A pulsation dampener in a mud pump, also referred to as a pulsation stabilizer, accumulator, or surge suppressor, holds a pivotal role within the realm of mud pumps. Its essential purpose lies in the regulation and minimization of pulsations or pressure and flow fluctuations arising naturally from the reciprocating movement of the pump.

Overview of Slips and Elevator Used in Upstream Drilling Industry

This article will explain the overview of slips and elevator which are very important tool on the rig.

Slips

Slips are wedge-shaped gripping devices which are used to suspend the drill string in the hole. They fit around the body of drill pipe and wedge in the taper of the rotary table’s opening. Slips have serrated inserts or dies that will grip the outside diameter of the tubular when it is set on the rotary table. To set the slips, rig crews place them around the pipe and the driller then slowly lowers the pipe until the slips can take up the load. The dies in the slips will firmly hold the pipe. In order to remove the slips, rig crew grasp the slip handles and as the driller picks up the pipe, they lift them out of the rotary table opening and set them aside.

You can watch this video to see how the rig crew set and remove the slips

Rotary Friction Welding for Oilfield Drill Pipe

This is very interesting to see how the body of drill pipe and tool joint together using the rotary friction welding.

The friction welding or FRW is solid-state welding process which generates the heat using the friction between the work pieces in relative motion to each other, with addition of lateral force known as “upset” in order to displace and fuse materials plastically. Technically, no melt takes place and in the traditional sense friction welding isn’t a process of welding, rather it is a forging technique. Because of similarities between traditional welding and these techniques, it has become a commonly used term. The friction welding is used with thermoplastics and metals in a variety of automotive and aviation applications.

What is Top Drive System?

A top drive is a big motor system which is hoisted in a derrick or mast of a drilling rig. A top drive is a modern rotating system which has been popular for many drilling contractors and oil operators. Top drives can be used on all types of rigs, from truck-mounted rigs to offshore rigs.

Rotation provided to a drill stem is accomplished by a top drive. Therefore, a Kelly and a Kelly bushing are not required for a top drive system. Moreover, a master bushing and a rotary table serves as support for slip and weight of a drill stem and as a conduit for a drill stem to be raised or lowed into a wellbore. Continue reading
