What is Water as Drilling Fluid in Geothermal Wells about?
1. The document discusses using water as a drilling fluid for the production zone of geothermal wells. Water can be used but requires high annular velocities (>40 m/min) for adequate hole cleaning to prevent stuck drill strings. 2. Aerated drilling fluids are an alternative that aid in hole cleaning and keeping fractures open to improve well productivity, but have additional costs compared to water. 3. Drilling records from Well X showed that between 1547-1625m, high viscosity mud was pumped in 6m interval
