When we begin drilling an oil well, the first section (surface hole) is one of the most critical phases where vibration plays a major role. Why vibration occurs:At this stage, large-diameter bits are used, usually with long Bottom Hole Assemblies (BHAs). The bit interacts with hard and variable formations near the surface, while heavy drillstrings […]

On a drilling rig, shale shakers are the first line of defense in solids control. Sometimes we see overflow on the shakers, which simply means that the drilling fluid and cuttings coming from the wellbore are too much for the shakers to handle. Why does this happen?-High flow rate or pump strokes pushing too much […]
