Further to previous announcements, the well intervention operations on SS-7 have now concluded. Following a complex mobilization to Songo Songo Island, the work program sought to restore the well’s mechanical integrity, shut off water production, and restart production from the southern compartment of the gas field.
Limited and unsustained gas flows were observed after successful water shutting and reperforating the Neocomian sands. In line with its contingency plans, the company set a cement plug above the Neocomian interval and perforated the shallower Cenomanian sands.
Having completed all possible downhole work, and after an unsuccessful attempt to produce gas from the Cenomanian sands, the Company has ceased well intervention operations and commenced demobilization of the barge and jack up from the SS-7 site. The total expected project cost has increased to $27 million from $22 million, primarily as a result of the significant attempts required to shut off water and reproduce the well.
Following demobilization, a comprehensive post-project analysis will be carried out to evaluate the intervention results, which have not met production expectations.
