GEOTHERMAL BLOWOUT & CONTROL EMERGENCY SERVICE

In 1995 , GPC was awarded by geothermal district heating operators an ad-hoc emergency/rescue contractaimed at controling well blowouts and avoiding subsequent damage , owing to a sensitive , densely populated , urban environment, a hot fluid (65 to 80°C) and the presence of flamable (methane) and toxic (hydrogene sulphide) solution gases. This preventing policy proved effective with five sucessful operations recorded to date.

SOFT ACIDIZING

Concept : long duration injection from well head of a strongly diluted acid solution (=<0,5%).
Aim : dissolving of scale peaks affecting casing roughness and subsequent friction losses.
Outcome : Achievement of substantial productivity/injectivity gains at costs lower than those of conventional acid jobs.
