WEST CHESTER, Pennsylvania, April 15 (Reuters) – The
backbreaking life of a roughneck, the iconic worker bees of
oilfield drilling rigs, is getting a little easier.
Schramm Inc, which built the drilling rig that four years
ago helped rescue 33 trapped Chilean copper miners, has designed
a 500,000-pound rig for the oil and natural gas industry that
can walk, rotate 360 degrees, be operated with a remote control,
and load pipe automatically.
