据3月27日Oil Now报道，埃克森美孚的第六艘钻井船Sam Croft已经抵达圭亚那近海。
该船最近刚刚从苏里南，位于58号区块的Keskesi East-1勘探区进行了更深层的钻探作业中解放出来，。
海上管理部门(MARAD)在一份通知中表示，该钻井船将在Stabroek区块内与其他钻井船只一起投入使用。该区块距离圭亚那海岸约59.8海里(110.8公里)，占地0.29平方海里(1平方公里)。
在Sam Croft钻井船到达圭亚那之前，2月Stena DrillMAX刚进入圭亚那水域进行钻探作业。
埃克森美孚提高圭亚那近海钻井能力的举措，是为了促进今年积极的勘探和评估活动，目标是在不同区块钻探12至15口井。这些井包括靠近现有发现的低风险井、高风险井，以及一些将测试更深的Campanian和Santonian地层的钻井。扩大后的项目将使Stabroek区块的合资企业加速勘探，实现未来开发的最佳顺序。
埃克森美孚已经利用Stena Carron钻探船在Liza东北约16英里的Koebi-1油田开钻，目标是类似Campanian的储层。Stena DrillMAX的目标是在长尾地区进行评估钻井，重点是下Campanian和Santonian地质层。
今年4月，埃克森美孚将使用Noble Don Taylor钻井船开钻Uaru-2评估井。此外，Mako-2油田将于今年晚些时候开钻，如果取得成功，Mako/Uaru地区将有望进入开发行列。
此外，埃克森还计划开钻位于Liza以东约12英里处的Whiptail-1探井，目标是Campanian和Sanantonian地层。

ExxonMobil’s 6th drill ship arrives in Guyana
The Noble Sam Croft has arrived offshore Guyana taking the total number of drill ships on contract with ExxonMobil operating in the South American country to six.
The Sam Croft was recently released from drilling operations in neighbouring Suriname where it tested deeper intervals at the Keskesi East-1 prospect located at Block 58.
The Maritime Administration Department (MARAD) said in a notice that the rig will be at a staging area within the Stabroek Block until April 15 and will incorporate the use of several vessels.
“The staging area is situated approximately 59.8 nautical miles (110.8 kilometers) from the Coast of Guyana and covers an area of 0.29 square nautical miles (1 square kilometre) …” the MARAD notice said.
The arrival of the Sam Croft closely follows the Stena DrillMAX which entered Guyana waters last month.
Exxon’s move to ramp up its drilling capacity offshore Guyana is to facilitate an aggressive exploration and appraisal campaign this year targeting 12 to 15 wells in a variety of play types. These include lower risk wells near existing discoveries, higher risk step-outs, and several penetrations that will test deeper Lower Campanian and Santonian intervals. The ramped-up programme will allow the Stabroek Block co-venturers to accelerate exploration and enable optimum sequencing of future developments.
Exxon has already spudded Koebi-1, located approximately 16 miles northeast of Liza, targeting similar Campanian aged reservoirs using the Stena Carron drillship.
The Stena DrillMAX is targeting appraisal drilling in the Longtail area, focusing on the lower Campanian and Santonian geologic intervals.
In April, Exxon will move to spud the Uaru-2 appraisal well utilizing the Noble Don Taylor drillship. Success here, and at Mako-2 which will be drilled later this year, could move the Mako/Uaru area forward in the development queue.
Exxon is also slated to spud the Whiptail-1 exploration well, located approximately 12 miles east of Liza, targeting Campanian and Santonian aged reservoirs.
