MAX-BRIDGE bridging solution improved wellbore stability on historically troublesome wells
In a mature field in East Kalimantan, Indonesia, an independent operator experienced massive losses in a series of wells, along with wellbore instability-related problems. The extremely low pore pressure typically found in these types of mature fields is problematic because the low pressure requires having enough drilling fluid density to stabilize the wellbore.
After several unsuccessful attempts using conventional lost circulation material (LCM) that contained up to 60 ppb of CaCO3 fine/medium and cellulosic materials in the active system, in addition to previous treatments with a competitor’s synthetic graphite, the operator decided to conduct additional analysis of the situation. The analyses involved using Baker Hughes, a GE company (BHGE), BRIDGEWISE™ engineering software and extensive lab tests using the BHGE MAX-BRIDGE™ advanced bridging solution.
