United States shale player Sundance Energy has continued its “drill and flip" strategy, selling non-core acreage in one basin in Colorado for $US116 million, while adding ground in the ­popular Eagle Ford region in Texas for an estimated $US60 million.

Commenting on twin deals announced on Monday, Sundance managing director Eric McCrady said the sale of the acreage in the Denver-Julesburg basin provided an attractive return for the Australian-listed company, as well as providing the ­opportunity to accelerate growth in a core area. Sundance shares rose 4.5 per cent to $1.04 as investors gave an initial thumbs-up to the deals.
