OIL EXPLORATION, APPRAISAL AND DEVELOPMENT
Senex Energy Limited (Senex, ASX: SXY) and its joint venture partners have completed the planned 30 well drilling program for FY14. The oil drilling program for FY15 will be announced in July 2014, with drilling expected to commence shortly thereafter.
Tornado-1 exploration well (PEL 104: Senex 60% and operator, Beach Energy Limited
(Beach, ASX: BPT) 40%)
EDA Rig 3 is drilling ahead on the Tornado-1 exploration well, targeting a total depth of approximately 2,200 metres. The rig commenced drilling on 26 May 2014 approximately
4 kilometres southeast of Mustang-1 on the western flank of the South Australian Cooper
Basin.
Tornado-1 is the first exploration well to be drilled from the results of the Lignum 3D seismic survey. The primary objective is the mid-Birkhead reservoir sands within a combined structural-stratigraphic trap. As secondary objectives, the well will evaluate the Patchawarra Formation and Namur Sandstone.
The location for Tornado-1 was selected on the basis of the same AVO/Inversion1 work used
to predict the presence of Birkhead reservoir in the Mustang wells. Further prospects identified from the Lignum 3D seismic survey will be drilled as part of the FY15 drilling campaign.

ASX AnnouncementMustang-2 appraisal well (PPL 243: Senex 60% and operator, Beach 40%)
The Mustang-2 appraisal well was cased and suspended as a future Birkhead oil producer after intersecting 6.4 metres of net oil pay updip of the Mustang-1 oil discovery. The well intersected 12 metres of gross sand, which is almost twice the thickness of the reservoir section intersected at Mustang-1 (refer Figure 1).
EDA Rig 3 commenced drilling the Mustang-2 appraisal well on 2 May approximately
570 metres northwest of Mustang-1. Mustang-2 was drilled to a total depth of 1,915 metres to evaluate the oil bearing potential of the mid-Birkhead Formation.

About AVO/Inversion enhanced seismic interpretation techniques
AVO (Amplitude variation with offset): This technique uses the changes in seismic reflection amplitude to determine rock-type and fluid content. Successful AVO analysis requires special processing of seismic data and modelling of rock properties with a known fluid content. When the rock-types and their seismic properties have been determined, it is possible to interrogate the seismic volume and find other areas where those criteria are met. In the Cooper Basin, this process can be used to predict the presence or absence of the Jurassic reservoirs and sealing shales.
Inversion: A mathematical process by which the components of seismic data are used to generate a model that is consistent with well data where rock and seismic properties are known i.e. the process of solving the inverse problem. In seismology, 3D seismic data, vertical seismic profiles and well log data can be used to perform inversion, the result of which is a model of geological layers and their thickness, density and seismic velocities. These data can be directly related to the quality of the reservoir rocks being investigated and is used on Senex's 3D seismic surveys to optimise well locations and to help define the limits of stratigraphic traps.
