Solids Control Systems - SCS - In House Training

Solids Control Systems - In-house training by PetroSkillsThis course can be conducted on site at your location exclusively for your staff. Drilled solids in a drilling fluid can, and usually do, cause many problems while drilling wells. Drilling fluids containing excessive drilled solids increase trouble costs or Visible Non-Productive Time [NPT]. These costs are usually easily visible because the drilling rig can no longer drill. Drilling performance can be impacted by drilled solids and, frequently, be unnoticed. This higher drilling cost penalty is frequently accepted as 'normal'. Drilling performance is significantly affected by excessive drilled solids in the drilling fluid and might be considered an Invisible NPT. The Invisible NPT cost can be significantly larger than the Visible NPT. The list of problems created by drilled solids include stuck pipe, lost circulation, excessive wear on expendables, drill string vibration, poor cement jobs, low drilling rates, poor cuttings transport in the annulus, poor log interpretation, formation damage, creating a formation fluid influx by swabbing [even when running casing], and excessive expenditures for waste disposal. Each of these problems will be addressed during the course. Drilled solids are easier to remove when they are large. This means that solids control starts at the drill bit. Cuttings should be removed from beneath the bit as soon as they are generated. Failure to remove the cuttings results in regrinding by the next row of bit teeth and decreases drilling rate. Cuttings removal from beneath the drill bit is improved by using drilling fluid containing few drilled solids. These cuttings must be brought to the surface without tumbling in the annulus. Cuttings transport will be discussed because it is essential for good solids control. Removal of drilled solids require an understanding of the performance of shale shakers, hydrocyclones, mud cleaners, and centrifuges. These are discussed in...
