American Petro-Hunter has begun drilling operations at the NOM1H horizontal well at its North Oklahoma project in the US.

NOM1H is the company’s first well in a planned series of horizontal wells designed to exploit the 100ft thick limestone known as the Mississippi Formation.

American Petro-Hunter president Robert McIntosh said that over the coming weeks, the potential of this well will dictate subsequent development and is a cornerstone to the company’s overall strategic plans for the project.

According to the company, the Mississippi Formation has been the focus of intense drilling and development activity, with large numbers of horizontal wells drilled and put into production in recent months.
