to Gil (Bahram Beg) on donkeys where it is refined. The pits and seepages stretch
across the Fars outcrop for a width of about 50 yards.
\ Gil (Bahram Be<d One or two unimportant seepages. There are four small stills here,
three of which are in working order ; they consist simply of retort and condensing
(a) A short distance N.W. of Gil. Sulphuretted Hydrogen and a little bituminous^ earth.
(h) Nuqtab Sadiq. Two or three moderate seepages, but very little sulphuretted hydrogen.
(mi) Between Nuqtab Sadiq and Farhad Beg four separate oil localities are seen :
(а) Three small pools of oil.
(б) A pool of water with a little oil on the surface ; just below is a sulphuretted
hydrogen pool.
(c) Three or four pools of oil.
(d) Two pools of oil, one large with a considerable quantity of gas bubbling up.
(mu) Farhad Beg. A seepage or two of oil. Another small refining-still is used here.
(ir) Half-a-mile N.W. of Farhad Beg. A spring of water with a little oil and a considerable
quantity of gas.
The refined burning oil from this area, whether due to more careful refining or to greater
intrinsic purity of the crude material, is much superior to that of Tuz Khurmatu or Kir m v.
(ii) Prospects of Boring. —The great compression of the Told and the presence, within a few
yards of the supposed crest, of such a large dislocation as the reversed fault described otter no
inducement to exploitation by boring. Deep boring is, I think, out of the question ; it is veiy
improbable oil “ pools ” would ever be encountered sufficiently large to pay. Nor is the area muc
more promising for shallow boring unless some particularly inexpensive form of plant can be devised
That the oil occurs N.E. of the fault rather points to the conclusion that it has been to some extent
prevented from escaping by the protective remains of some sort of anticlinal structure ; the gassiness
of some of the seepages may be mostly due to sulphuretted hydrogen. It seems quite probable tin
the plane of the fault is parallel for some way down with the axial plane of the anticline, but tn
latter is, in any case, too tight to hold oil in any quantity. Hand-dug wells might perhaps pay m
places, but these or shallow borings are a pure gamble. Any tests should, of course, be located .
of the limestone core, preferably perhaps where this is seen to form high ground.
