It is when a hole is worn in the pipe, and becomes increasingly larger due to circulating drilling fluid. This can eventually sever or twist off the pipe entirely. Washouts usually occur at rotary connections, due to improper make-up, cracks or defective materials. From the surface, a washout may be indicated by a gradual decrease […]

Is equipment used to remove entrained gas in drilling fluid so it prevent or minimize reduction of hydrostatic pressure due to gas cut mud. When drilling mud passing over the shale shakers while drilling, gas will normally be released. However, the wellbore could receive additional volumes of gas and these need to be removed from […]

Wiper Trip is often made before running the casing. This is because it is essential that the casing, once started in the hole, reaches the planned casing setting depth with minimal trouble. Therefore, the hole must be in the best possible condition before running the casing. On the last trip out of the hole (or […]

Pieces of rock that came from the wellbore but that were not removed directly by the action of the drill bit. Cavings can be splinters, shards, chunks, and various shapes of rock, usually spalling from shale sections that have become unstable. The shape of the caving can indicate why the rock failure occurred.

A hydrocarbon compound that often precipitates on production components as a result of the changing temperatures and pressures within the production system. Heavy paraffins occur as wax-like substances that may build up on the completion components and may, if severe, restrict production. Paraffin is normally found in the tubing close to surface. Nevertheless, it can […]

The tricone drill bit for sale employs several drilling mechanisms to effectively cut through rock formations. These mechanisms include: Crushing:The teeth on the cones exert downward pressure on the rock, causing it to crush and break apart. Chipping:As the teeth make contact with the rock, they chip away at the surface, creating small rock particles. […]

Hydraulic Catwalk and Casing Running Tool Combine Cost and HSE Improvement Application in Deep Wells Top Drive Casing Running Tool fills, rotates, circulates and reciprocates the casing string simultaneously, thus improving the ease with which casing strings are run to desired target depth, even with troublesome or difficult hole conditions especially Deep Wells,ERD,HPHT,Gas Wells Improvement […]

Represents a critical process in the oil and gas industry, where a cement slurry is squeezed through perforations in casing to create a seal in specific locations, bridging undesired gaps. It is a common misconception that the cement penetrates the pores of the rock. Instead, the cement slurry dehydrates against the formation walls, forming a […]
