石油设备网讯 据管道新闻网3月21日消息称，负责Midale业务的卡地纳能源有限公司在2018年的工作重点是通过钻探新油井和继续优化现有生产基地内的增强型采收率作业，改善和提升其核心资产。卡地纳投资2140万美元，在其阿尔伯塔省和萨斯喀彻温省的资产基础上钻探、完井、装备和打井17口。此外，该公司还钻了15口地层测试井，进一步确定了艾伯塔省班特里地区埃勒斯利和格劳克水道的位置。
在阿尔伯塔省南部，卡地纳公司继续通过三口成功的水平井成功开发Glauc通道。经过7个月的生产，这3口井目前总共生产了550多桶/天。
“此外，由于我们采用了现代化的井筒和完井设计，与我们之前在该地区钻的Glauc通道井的成本相比，卡地纳公司实现了这三口井的综合成本降低13%以上。”
提高采收率下的主要石油生产资产继续得到优化，注入量将流向预期反应最显著的地区。在Midale，该公司主动增加注入的二氧化碳量，并将这些产量引导到油藏中最合适的位置，这导致产量下降不大。
该公司表示:“在整个公司，这些努力的效果最好地体现在对已探明的已开发生产储量的积极修正上。”

Cardinal plans two Midale wells
Cardinal Energy Ltd., which operates the Midale Unit, focused in 2018 on the improvement and advancement of its core assets through both the drilling of new wells and the continuing optimization of enhanced recovery operations within its existing production base. Cardinal invested $21.4 million in drilling, completing, equipping and tying in 17 (10.6 net) wells on its Alberta and Saskatchewan asset base. In addition, the company drilled 15 stratigraphic test wells which served to further delineate its Ellerslie and Glauc channel locations in the Bantry area of Alberta.
In southern Alberta, Cardinal continued with its successful development of Glauc channels via horizontal drilling with three successful wells. In aggregate, these three wells are currently producing more than 550 boepd after seven months of production.
“Furthermore, with our modernized wellbore and completion design, Cardinal realized an all-in cost reduction for these three wells of more than 13 per cent, when compared to our costs for previous Glauc channel wells drilled in this area.”
Major oil producing assets under enhanced recovery continued to be optimized, with injection volumes being directed toward areas expected to respond most significantly. At Midale, the company’s initiative to increase injected CO2 volumes, and to direct those volumes to the most appropriate locations within the reservoir have resulted in a distinct shallowing of the production decline.
“Throughout the company, the effects of these efforts is best illustrated by positive revisions to our proved developed producing reserves,” the company said.
