Abstract
ABSTRACTA unique, local powder additive was reactive to stopped mudflow underground blowout in Porong Sidoarjo and helped stabilize the borehole. The unique powder contains local lime, earth stability, API Oil Cement and obsidian glass (ceramic microsphere), so it can be used as a light weight additive for cement slurry. In geothermal fields, the reservoir temperature (up to 110°C)and steam caused the change of calcium silicate hydrate gel to alpha dicalcium silicate hydrate in the cement model composition, cement degradation and shrinkage, and borehole instability. The effects of HTHP conditions on the cement suspension were dehydration (partial liquid loss), fuggy channeling, shrinkage of the bulk volume, strength degradation, and an increase in the permeability of the cement. For the anticipated cement degradation to added by obsidian glass is 35% BWOS at term conditions. Research was carried out to model the composition of the unique powder slurry for mixing with mudflow in Porong Sidoarjo in order to anticpate strength degradation, volume shrinkage, low permeability, plugged zone fracture and isolated mudflow to the surface
