Jolly Ranch Operations Update

Nighthawk, the US focused oil development and production company (AIM: HAWK and OTCQX: NHEGY), announces an update on the recompletion and completion operations underway at Jolly Ranch.

Highlights

·; Nighthawk is currently focusing on a series of completions and recompletions on six previously drilled wells

·; The objective of the current exercise is to assess new and existing horizons to build value and prove up the Jolly Ranch acreage

Update on Completion Operations

As previously announced, following a period of technical review, including the undertaking and analysis of Pulsed Neutron Logs, the current activity on the Jolly Ranch project is the completion and recompletion of a number of intervals in selected wells, as per the table below. Pulsed Neutron Logging bombards formations with neutrons and detects gamma rays from the resulting interactions. It is rapidly becoming a complete stand-alone, cased-hole evaluation logging method. These measurements assist in the evaluation of porosity and the location of bypassed oil zones.

This work reflects the ongoing development of test production and completion exercises to help establish the optimum horizons and completion techniques to unlock value across the Jolly Ranch project.

The current operations will see the following wells either re-perforated and treated in previously completed zones or perforated and treated in new horizons.

The results of these operations will be evaluated and used to plan further completion exercises involving the use of artificial fracturing and completion consultants with experience of working on shale oil projects.

In addition, an internal technical assessment is currently being undertaken to assess the potential to drill in the Northern section of the acreage held at Jolly Ranch, the Middle Mist area, with a coiled tubing unit to target the shallower Niobrara formation.

Whilst there is as yet no firm plan to drill this well, it could form part of the previously announced drilling campaign which is anticipated to commence in the next few months. The use of a coiled tubing unit would permit a quick and cost effective method of testing the Cretaceous aged Niobrara shale formation, which is currently the target of numerous wells in the Northern part of the Denver-Julesburg Basin.

Production Updates

The Company intends to provide end of quarter updates on production volumes on an ongoing basis. These figures will represent production net to Nighthawk, including deductions for Royalty and State Production Taxes. Production figures for the quarter ended December 2010 will be issued once they have been fully compiled by the Company's accounts team, which is expected to be in approximately six weeks time.

Tim Heeley B.Eng (Hons) a member of the Society of Petroleum Engineers, Fellow of the Geological Society of London and a Chartered Energy Engineer, who is CEO of Nighthawk and has over 14 years of experience in the hydrocarbons industry, has approved the technical information contained in this announcement.
