This paper describes procedures and available technologies that allow for efficiently managing drill pipe lifecycle integrity. The paper will discuss the possibilities that digital asset tracking...

... Abstract Direct Electrical Heating Pipe-in-Pipe (DEH-PiP) has now been around since its development and installation by Shell in the early 2000’s. It is a well-known and field-proven solution for subsea flowline heating, but it exhibits a relatively poor electrical efficiency compared...

Determining these properties requires testing and analyses, and becomes even more challenging when multilayer thermoplastic pipes for high pressure hydrogen applications are considered. This is where...

... coefficients under 2-phase flow regimes and validate cooling of heating coil by surrounding water. A dedicated test loop has been built for these tests in order to operate the prototype (4 inch OD pipe) under a wide range of air & water 2-phase mixture at atmospheric pressure. The prototype is submerged...

... is gaining its eminence compared to conventional drilling with drill string. When realized and implemented appropriately, casing drilling delivers significant cost savings due to elimination of pipe tripping in and out, borehole stability/instability, no need to buy or rent drillpipes and etc.. Nonetheless...

... Abstract Spoolable pipes are of great interest in O&G industry: they offer well-known advantages like high resistance to internal and external corrosion and low roughness, high fatigue resistance, reduced maintenance cost and improved flow rates. Another important advantage is the easy...

... for strength, weight reduction and corrosion resistance are briefly introduced. They use pultruded carbon fibre composite rods as tensile strength elements or thermoplastic composite pipes (TCPs) as the complete riser section or as a layer in an unbonded flexible riser wall. These concepts provide the bending...

... transfer between the fluid in the annulus and the formation is considered. The approximate method is adequate, since the total heat transfer between the fluid in pipe and the fluid in the annulus is much greater than that between the fluid in the annulus and the formation. Some measured field values were...

... coated pipes was used, pinned at the ends; the weld areas being where the loads were applied steel-to-steel. An array of LVDTs was used to monitor test string position relative to a fixed datum, and so confirm curvature and therefore strain. Curvature data was plotted against geometrically perfect arcs...

The most interesting result presented in this work is a correlation which allows the liquid hold-up in a vertical pipe to be derived from a differential pressure measurement rather than using...
