The objective of Ellis-2 is to evaluate the lower Morrow B, Morrow C, D, E and Itoka sands that are interpreted to be gas bearing in Ellis-1. This well will be drilled to a similar total depth of approximately 11,500 feet.
Ellis-2 offsets a previously drilled well which flowed gas at a rate of approximately 2.4 MMscf/d. Other nearby wells have Morrow gas pay interpreted from the wireline logs, but were either not tested or failed to flow, which Amity has interpreted to be a consequence of the poor drilling practices employed at the time.
“The use of synthetic oil-based drilling mud and a superior well design should eliminate the risk of formation damage and maximise well productivity,” said Amity managing director Howard McLaughlin.
“Ellis-2 is targeting un-risked reserves of between 2.0 Bcf and 10 Bcf in the P90 to P10 range per well in the Morrow B only. The most likely estimate of the un-risked gas reserves are between 3 and 5 Bcf per well. Should additional pay be confirmed in the other Morrow targets then additional gas volumes would be attributable to this well.”
A fracture stimulation crew is scheduled to arrive at Ellis-1 on 30 October. A multiple zone frac is planned over the three or four best gas zones as interpreted from the wireline logs. Plans are also underway to connect the well to existing gas pipelines near the location.
