Drilling Sweeps Optimization Based On Downhole Measurements

Hole cleaning is an important consideration when drilling any type of well and it becomes more<br>difficult as hole angle increases. Drilling sweeps are used to improve the removal of solids from the<br>wellbore. However, the indiscriminate use of sweeps can often lead to higher costs and even<br>hamper hole cleaning if not used properly. Selection and use of sweeps is historically carried<br>out using local experience and qualitative indicators.
