Published: 01 November 2002
... to tubular-deposition problems. We took two approaches for laboratory investigation. In the first approach, a gravimetric technique was used to establish asphaltene onset pressures ( p ao ) at various temperatures, leading to the generation of the asphaltene flocculation envelope (AFE). The second approach...

... required an average of 69 days to drill to total depth through the abnormal pressured Redfork zone. The uneconomic AFE dry hole cost estimate was based on 60 days. The principle expenditures of the AFE cost estimate were thoroughly analyzed. The tubular program was determined to be the minimum required...

... and production casings, and by unknown cement tops. Failure of these tubulars during production could potentially damage the production tubing or, in the extreme, lead to breach of hydrocarbons at the mudline. Decision analysis is used to quantify the uncertainties in the problem and, by systematic means...

... al. 2007 ; Kang et al. 2016 ). Consequently, APB is a major concern in HT/HP well design, such as in deepwater wells. When an APB becomes high enough to potentially result in well tubular failure and well integrity issues, APB mitigation methods should be considered ( Liu et al. 2016a , 2016b...

.... As such, all 17 well slots required tubulars to be cut and then recovered to surface, where they were required to be cold cut to manageable lengths, then laid down for back-loading operations off the facility. The initial cuts on the tubulars are required below the mudline per local legislation, to allow...
