Last week Amity announced it had encountered nine gas anomalies at the Adatepe-1 well, making it commercially viable.

Preliminary interpretation of wire-line logs shows the well has intersected five gas zones totalling 51.3m of gross pay (28.8m net), spread over a vertical section of 269m, in separate sandstones in the Danismen Formation. The thickest single gas zone has 17m net in reservoir sandstones of comparable quality to those in the Gocerler Gas Field.

The other four gas zones have a combined gross pay thickness of 17.6m, of which 11.8m is net.

Yesiltepe-1 is a wildcat exploration well and will test a major onshore structural prospect near the Turkish Mediterranean coast, close to substantial gas markets and crude oil handling facilities.

Drilling will be put on hold for a few weeks following delays in the delivery of equipment, but already a 26 inch diameter hole has been drilled in preparation for cementing in a 20 inch diameter conductor casing.

The Yesiltepe prospect is a high relief anticline in Miocene age sediments, similar to those at Amity's Gocerler Gasfield. The structure has been defined by 2D seismic shot by Amity early this year. Reprocessing of some old seismic also assisted with structural definition.

A number of nearby, but off-structure old wells, have tested oil and gas, or had strong shows during drilling, from stacked sandstone reservoirs in the same rock sequence which will be drilled in Yesiltepe-1.

Amity estimates that the Yesiltepe anticline has a "most likely case" (P50) recoverable reserve potential of 270 billion cubic feet of gas, or 140 million barrels of oil, if hydrocarbons are present. The "maximum case" (P10) is 1028 billion cubic feet of gas or 536 million barrels of oil, if hydrocarbons are present.

Amity holds 100% of the prospect, but intends to farm out up to a 40% interest to assist with funding the well cost.
