The plan is to recommence development of the Cardiff deep gas discovery, targeting the various gas/condensate zones with horizontal-drilling and multi-stage fracturing developed specifically for these types of tight-sand gas reservoirs. Porosities and permeabilities found within the multiple Kapuni Sands Formation zones encountered in the Cardiff-1 (5050m total depth), Cardiff-2 and Cardiff-2A sidetrack (4931m total depth) wells are analogous to prolific tight-sand formations in Germany, Holland, the North Sea and North America, where new technologies have been successful in achieving dramatic increases to oil and gas flow rates and overall reserve recovery.
Access to market for Cardiff gas is relatively straightforward, seeing as it’s situated just 3-km from a tie-in to TAG-owned gas infrastructure. This tie-in provides a link to the high-capacity LTS gas pipeline and the thriving North Island gas market.
