(1)
A productive well is an exploratory, extension or development well that is not
a dry well. A dry well is an exploratory, extension or development well that
proves to be incapable of producing either oil or natural gas in sufficient
quantities to justify completion.
(2)
A stratigraphic test well is drilled to obtain information pertaining to a
specific geological condition and is customarily drilled without the intent of
being completed. Stratigraphic test wells are ‘exploratory type’ if not drilled
in a known area or ‘development type’ if drilled in a known area.
(3)
The number of wells being drilled includes wells that have been drilled, but
have not yet been mechanically completed to enable production. Wells which
are awaiting only surface connection to a production facility are considered to
be completed.
(4)
An extension well is a well drilled to extend the limits of a known reservoir.
(5)
Drilling activity included up to 25 February 2021, which was the effective
date of divestment of our interests in the EMP in Gabon.
(6)
Sasol signed an agreement to divest of all our interests in Canada. The
transaction closed on 29 July 2021.
The table below provides details about natural
oil and gas capitalised exploratory well costs at the end
of the last three years, showing additions, costs charged
to expense and costs reclassified.
The table below provides total gross and net
developed and undeveloped acreage for our natural oil

The table does not include acreage information (neither net nor gross) pertaining to:
licences from which Sasol is in a formal process of withdrawing; licence areas
proposed for relinquishment owing to local regulations; or new blocks Sasol is in a
process of acquiring. See the map on page M-2 to M-3 for a representation of the
affected areas.
(2)
Certain licences in Mozambique and Canada overlap as they relate to specific
stratigraphic horizons.
