... the functionality of self-healing. In this context, small microfractures or microannuli may be sealed over time when the cement system is exposed to CO 2 . This system was qualified following extensive CO 2 exposure where the mechanical properties were assessed before and after testing. This step was added...

... The primary objective of the program was to increase potential well productivity by increasing the well exposure with the producing formation ( Rahman and Al-Awami 1995 ). Drilling extended-reach wells (ERW) involves critical issues that can pose a significant challenge for the operator...

... to conventional diesel, thereby leading to better air quality on drilling locations. A recent study which assessed emission and personal exposure levels to various hydrocarbons at key phases of drilling operations confirmed that significantly lower hydrocarbon exposures occurred for mud systems based on Saraline...

In addition, the determination of mercury in natural gas and condensate is made difficult by the very low concentrations involved, the highly volatile nature of mercury and the complexity of the sample matrix. This dictates...

The need for effective, tried and tested solutions to mitigate the risks posed by cryogenic liquid gas exposure was identified nearly 20 years ago. In the last 10 years, as the FLNG industry has accelerated, development...
