  • The wellbore has tested all objectives

  • Porosity logs were acquired and objectives deemed non-commercial

Byron Energy Limited (“Byron or the Company”) (ASX: BYE) advises that the Byron operated Weiss-Adler, et. al. No. 1 well (“Byron Weiss-Adler #1”) was drilled to a depth of 17,766 feet Measured Depth (“MD”). As of 3:00 pm US Central Daylight Time on 10 October 2018, the Byron Weiss-Adler #1 well has been evaluated utilizing quad combo wireline logging tools, has been deemed uncommercial, and is currently being plugged and abandoned.

Byron or the Company Byron, as operator, has drilled to a measured depth of 17,766 feet and has determined that the objectives were penetrated, and the prospect has been fully tested. All parties have been notified and have elected to plug and abandon the well. Wireline logs including a sonic (P&S wave), neutron/density, gamma ray and resistivity tools were run and evaluated. Byron has generated a synthetic seismogram to confirm the tie to the Company’s seismic data to ensure the well has been drilled to a depth sufficient to test the two objectives. Petrophysical evaluation of the porosity and sonic logs indicates the first objective to be a water bearing sand and the second objective a set of thinner, tight, gas bearing sands and shales with less than 5 net feet of conventionally logged hydrocarbons.

Although P&A operations will be ongoing into next week. The Byron operated well has been drilled safely and efficiently utilizing the Parker Drilling Company Rig #77-B, which was managed by Stokes & Spiehler, Byron’s primary consulting drilling engineers. The well reached total depth and has been fully evaluated in near record time. Estimated final costs to drill, test and abandon the well are currently expected to be less than US$7.5mm and significantly below the original expectations of US$10.8mm.

Byron Energy Inc, a wholly owned subsidiary of the Company, is the operator of the Byron Weiss-Adler #1 well, has a 43% working interest and a 32.035% net revenue interest in the well. The participants and their respective interests in the Byron Weiss-Adler No. 1 well are shown below.

CEO Comment had this to say regarding Bivouac Peak:

While the result was certainly not what we were looking for, the efficiency and cost-effective manner in which this deep, complex well was operated is a testament to the dedication of the entire Byron team.

I am pleased with the professional manner in which the joint venture drilling effort was managed and thank our Bivouac Peak partners for their participation. “
