Mesa energy said its Reisdorf Unit 1 well in the northern portion of the Java Field has been successfully plugged.

The US well has been pulled back to a depth of 2,400ft and existing casing has been removed to a depth of 1,529ft, the company said in a project update.

“The stacked shales of the Hamilton Group above the Marcellus create an engineering challenge but also provide significant additional opportunity for development of natural gas reserves in the region,” said Mesa Energy Holdings CEO Randy M Griffin.
