TOTAL and Apache are chasing deeper targets at their latest ongoing well offshore Suriname, which has thrown up the partners' fourth discovery on the prolific Block 58 in little over a year. The French supermajor -which has just taken over from US independent Apache as operator of Block 58 - late last week revealed that the Keskesi East-1 wildcat had unearthed what it termed a "significant" oil and gas discovery, hitting a total of 63 net metres of hydrocarbons. Of this total, 58 metres was "net black oil, volatile oil, and gas pay in good quality Campano-Maas-trichtian reservoirs", Total said. There was also five metres of "net volatile oil pay in Santonian reservoirs, where wireline logging has just been performed", the operator added. Houston-based Apache noted: "Fluid samples indicate API oil gravities of approximately 27 to 28 degrees in the Campanian and 35 to 37 degrees in the Santonian."
