| Abstract | Four deep wells were drilled in the Asal Rift Area in the Republic of Djibouti from June 1987 to July 1988 Q I Two of them, wells Asal 3 and Asal 6, were productive. Well Asal 3 was extensively tested for about 4 months. Measurements taken during the long term production test showed the following features : a) High scale buildup was observed at the surface f a c i l i t i e s ; the scaling was composed mainly of sulphides (galena and sphalerite) and amorphous silica. b) Well output strongly decresed in time, specially at the higher flow rates range. Down-hole pressure at a given flow rate decreased but the transient testa did not indicate an increase in skin factor. d) A caliper log showed that only a limited decrease of production casing diameter occurred the two-phase section of flow. |
