A recently developed electromechanical precision pipe-cutting tool is being field tested. Its primary applications are to cut and free stuck pipe (tubing or drillpipe) or cut pipe to modify a production completion installation. Cutting pipe in today's complex completions presents many challenges. Testing of this new cutting technology has demonstrated significant advantages over previously used equipment. It is non-ballistic, has a large cutting range for a wide range of metal pipes, provides cut monitoring and success detection. The precision of the cut is facilitated by the tool's internal programming (smart function) which allows for specifying the type of metal to be cut, monitoring the depth of the cut, recognizing the drag and making the appropriate adjustments to complete a cut. The ability to complete multiple precise cuts reduces associated rig time. Its large operating temperature and pressure ratings (20,000 psi), large cutting size range, and portability make possible quick deployment to offshore and land operations. Additional field-demonstrated capabilities include: performs accurate smooth cuts, cuts harder metals with a high chrome content, performs precision cuts for inner pipe cutting, works at any deviation, produces minimum debris, surface system allows application to any wireline, does not require circulation holes for the cutting device, operation deployment is not constrained by chemical issues relate to safety and environment, the cutter's light weight, short shipping length (two sections, each less than 10 feet in length), and compatible portable support equipment allow for quick deployment in a variety of transport modes. This paper includes a case study to illustrate the operating challenges associated with tubing and drillpipe cutting in a variety of conditions and environments.
tell me that today more people laughed than cried, and more children were born than died. tell me I won't go crazy if you were not at my side and the world won't get dizzy from spinning round.tell me that today more love was found than lost, and the sacrifices were worth the cost. tell me I can give my all and never exhaust, and I'm not gonna fall if I look down.if I don't go to sleep, will I ever have to wake? if I ignore it all, will it all disappear? if I don't hear the fall, did it really make a sound?if I grew wings, could I fly away?tell me that today, there was more hope than fear, and tomorrow I wouldn't rather be anywhere but here, and when I turn to you, you will always be near, so you can end the darkness with your light.tell me that today, in reality, there was a lot more good I just didn't see. tell me I'll always believe what I tell you to tell me, and you will always lie to me out of love.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
