Summary:
Palmyra is a dry gas field located northeast of the town of Palmyra in central Syria, in the eastern part of the Hayan Contract Area. Palmyra structure belongs to the tectonic province of the southern Palmirydes. The field is covered by 340 km2 3D survey. The main target is Markada Formation. Markada sandstones, as part of Carboniferous Markada Formation, are main Paleozoic gas bearing reservoirs in Palmyrides. In clastic depositional system, nearshore, deltaic distributary mouth bar and/or channel sandstone were intercalated with shale. Markada formation is subdivided into several reservoir/layers A, B, C and D. Target reservoirs have been hardly traceable on conventional seismic and common seismic attributes were difficulty related to any certain lithology or possible gas saturation. Due to good production results on Palmyra gas field it was decided to better explore nearest area and to find location for a new Well-C. In order to evaluate and explore possibility of additional hydrocarbon accumulation, it was necessary to perform additional analyses such as seismic attribute analyses and Neural Network logs properties prediction to better characterise Palmyra reservoirs.
