Dynamic Buckling Of Coiled Tubing During A Completion/Workover Application

ABSTRACT: The purpose of this paper is to present how hand-calculations and a general finite element analysis program can be utilized to determine under what conditions coiled tubing (CT) could buckle helically in a vertical well. This is especially useful when determining loads on...

Load Extrapolation Methods for Offshore Wind Turbines

ABSTRACT Statistical load extrapolation is required to predict long-term extreme loads for offshore as well as onshore wind turbines, as per design standards from the International Electrotechnical Commission (IEC).  Load extrapolation involves three major steps: first,...

Calculation of Finned Tube Pressure Drop and Heat Transfer Using Fully Three-Dimensional CFD Methods

ABSTRACT The use of computational fluid dynamics (CFD) in the design and troubleshooting of HRSGs is now well established. However, the large ratio of scales between the overall flow path and the tube bundles themselves means that the bundles must be approximated using “porous...

UBD or MPD: An Engineering Choice Based on Intent, IADC/SPE 130563

 ABSTRACT: Often times reservoir and drilling engineers are faced with the decision on how best to construct a well to exploit zones of interest while seeking to avoid drilling problems that contribute to reservoir damage or cause loss of hole. The decision to pursue either...

Simulation of Offshore Wind Turbine Response for Long-term Ultimate Loads

ABSTRACT When there is interest in estimating long-term extreme loads for an offshore wind turbine using simulation, statistical extrapolation is the method of choice.  While the method itself is rather well-established, simulation effort can be intractable if uncertainty in...

Managed Pressure Drilling: What It Is and What It Is Not

ABSTRACT Within the context of broad industry recognition of two drilling technologies, Underbalanced Drilling predates Managed Pressure Drilling (MPD) by at least a decade. While there are some similarities in some of the equipment and possibly in some of the techniques, the...
