drill pipe 200ft per day, page-4

Neilwa, First it takes about two to four hours to make up the wash over pipe, the bit is only about one inch thick it is real easy to brake. Then you run all that in to the top of the fish, have to run real slow as you have very little clearance, may be six to eight hours, now we circulate the well clean one hour, now we start to wash over, six to twelve hours, pull the lot out of the well, six hours. Now comes the sh!t part of the whole operation, you have the wash over pipe with the drill pipe in side it, remove all this six to seven hours. Now we are ready to start again. Now this time we check that the bit is still good, all so twenty% of the wash over pipe will have to be replaced as it is very thin and gets out of shape real easy.
