Shares in Weir, which makes pumps used in extracting shale gas, were trading down 0.4 percent at 2,316 pence by 1314 GMT, recovering from a session low of 2,274 pence.
"I am introducing a generous new tax regime, including a shale gas field allowance, to promote early investment. And by the summer, new planning guidance will be available alongside specific proposals to allow local communities to benefit," Osborne said.
"Shale gas is part of the future. And we will make it happen."
