Drill pipe is one of the most critical equipment on a deepwater Drilling Rig and Drill pipes incidents are one of the biggest causes of nonproductive time and unplanned costs in the drilling industry. In most cases...

... Abstract The past three decades saw the introduction of several generations of double-shouldered drill pipe connections with performance as a primary development focus. The record extended-reach drilling (ERD) wells could not have been drilled and completed without these technological...

... been mitigated using high torque drill pipe and torque reduction tools. Reamer and back-reaming out of hole have been used to smoothen wellbore which facilitate wireline logging and casing running operation. Eccentric casing shoe and low-friction centralizers have been used to further aid running...

... with an optimized string design, drillers sometimes have no other option than to sacrifice the margin of overpull, risking losing the well if fishing is unsuccessful. Alternatively, they can elect to use drill pipe, which is not suited for use in this corrosive environment, generally using API S135, with a risk...

... the engineers have into which software modelling or input is crucial in which circumstances. For this, a study of well design parameters including well architecture, drill pipe selection, BHA type, drilling fluid and tortuosity, will elaborate the extent to which these variables have influences on the torque...

... and extends the application of data into wells that are technically or commercially challenging for conventionally-sized tools (such as slim and/or high dogleg severity wells, and wells where logging out of drill pipe may be the only cost-effective evaluation option). Innovations in the design of the flexural...

... should not exceed the connection MUT. Drilling torque that exceeds connection MUT may cause downhole makeup, connection damage or connection failure. Finally, another advantage in the running characteristics of 3 rd Gen DSC was reduction of MUT for larger drill pipe sizes. The MUT of some 2 nd Gen...

... was introduced with the application of Top Drive, additional third 1700 HP mud pump and larger 5 1/2" O.D. drill pipe. This resulted in a step-change improvement in drilling performance. In 2003 KOC began a project to look into the radical re-design of the deep rig specifications. Hamad Al Hamad and Partners...

The complete UBD closed-loop flow control system comprises of the drill pipe (DP) circulating system, a UBD control device (UBD-CD), which provides the sealing mechanism around the drill string at surface, a UBD choke manifold (not the rig’s well control choke manifold...

... and at the lowest economic cost. This quest for efficiency led to selecting a slim hole drilling program that is completed within days, and as such, puts a lot of stress on the drilling equipment and in particular the small size drill string. Over the years, the size of the drill pipe used to drill the production...

However with these advantages come some drawbacks, the chief among which is the safety of the operation while tripping the drill pipe into and out of the well. Since the well is allowed to flow in traditional UBD...

... Abstract Improvements in horizontal drilling technology made it possible to drill almost in all types and shapes of reservoirs. No change, however, was made in the design of drill pipes to overcome the high stresses especially for drill pipe rotating in medium or short radius horizontal wells...
