W&T Offshore, Inc. reports that its Ship Shoal 359 A-18 well has logged 149 ft of net oil pay in five zones and extended the size and depth of its Mahogany field. 

The SS 349 A-18 well was drilled on the western side of the Mahogany field to extend the productive limit of the 'T' sand, which was discovered in mid-2013 by the A-14 well. The A-18 well not only confirmed that the 'T' sand is present and oil bearing on the west side of the field but it also logged and penetrated four additional attractive pay sands in addition to the main 'T' sand target. 

After casing the 'T' sand, the company says it drilled an exploratory tail (approximately 950 ft deeper) beneath the main well target to test seismic reflectors imaged with its newest 3D seismic data and discovered an additional pay interval in a deeper 'U' sand interval. The success of the A-18 well is expected to generate additional drilling locations for the company. W&T holds a 100% working interest in the Mahogany field.

Tracy Krohn, W&T Offshore’s Chairman and CEO, stated: “After pausing our Mahogany field development drilling program since early 2015 when commodity prices slipped, we are very pleased to have resumed drilling activity there to further unlock the significant potential of this huge field. We are benefitting from our recent analysis of our new WAZ seismic data over the field, which allows us to more clearly image the sub-salt formations and assess the additional upside of this field."
