... on the experience of various operators in different drilling environments, planning in the use of solid expandable tubulars can be a key to reducing flat time. The Drilling Curve The drilling curve has been around for years. When wells are in the Authority for Expenditure (AFE) generation stage, the curve...

... 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...

... Abstract The field development of Tubular Bells, in the Mississippi Canyon (MC) area of the Gulf of Mexico, began with a nine-well batch set drilled riserless in water depths of approximately 4,500 ft. The batch drilling concept was implemented to mitigate the risk of various shallow hazards...

In addition to this, the method of executing these operations further increases the efficiency of them, and ultimate effectiveness...

... 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...

Specialized handling equipment is required for the tubular boring, handling and cutting operations, integrated at drill floor...

... in wellbore temperature: Connection Leak Considering the production tieback, high volume production induces (a) axial compression due to thermal stress and (b) incremental increase in external pressure due to AFE. These loads move the tubular stress state into the 3 rd quadrant of a conventional von...

... 'af', then the number of stress cycles for the requisite amount of crack propagation may be expressed as: 0 N m--1T 2 (3) CAe. The end of fatigue life is determined by the onset of unstable crack extension. For tubular joints, propagation life ceases as soon as the crack grows through the full...

... ABSTRACT A technique for predicting the fatigue life of axially loaded nonoverlapping tubular K-joints has been developed using fracture mechanics. This method relies on an experimentally determined stress intensity factor, K I as shown in Figure 1. In this application K I was derived from...
