... Inherently, running wireline tools with radioactive sources in an un-cemented and un-cased section of OH exposes the operation to considerable risks. Common exposure risks include logging hold ups due to wellbore bridging, wireline tools stuck due to differential sticking across depleted zones...

... in well abandonment projects represents a significant progression and can help provide detailed answers to the three basic questions in managing project costs: What is the likelihood of overrunning the project budget? What is the level of exposure associated with any overrun that may occur? Where...

... value of nano-SiO 2 geopolymer cement gives benefit in maintaining high strength value after acidizing. Sample NG1 with 1% nano-SiO 2 obtained the highest strength value and minor crack after 24 hours acid exposure. The result shows that the new cement system can improve the wellbore integrity...
