据普氏能源资讯休斯顿3月1日消息称，西南能源公司官员周五称，随着去年年底出售费耶特维尔页岩资产，西南能源计划加强对阿巴拉契亚盆地的关注，在广阔的干气和富含液体的土地之间平衡钻探努力。

在发布第四季度和2018年全年业绩时，该公司报告称，2018年，阿巴拉契亚地区的总产量同比增长了21％，达到7020亿立方英尺（相当于19.2亿立方英尺/天），而液体产量同比增长40%，达到63100桶/天。

该公司报告称，经去年12月费耶特维尔资产出售调整后，今年的总产量为9460亿立方英尺(25.9亿立方英尺/天)。

公司总裁兼首席执行官Bill Way在与分析师的电话会议上说：“我们拥有大量的高品质土地组合，包括多个工作台，以及大量天然气液体和天然气领域的高价值投资机会。”

公司官员表示，去年西南能源公司通过使用延长侧向钻井等技术，改善了井况和作业效率

公司执行副总裁兼首席运营官克莱顿卡雷尔在电话会议上说：“我们每口井的侧向钻井深度都超过了1.5万英尺，其中一口井的侧向钻井深度创下了公司近1.62万英尺的记录，而且这三口井都按时、按预算完成。”

展望未来，他表示，该公司在2019年继续测试超长侧向地层，并指出西南能源公司上个月弗吉尼亚州西部钻探的1.8万英尺钻井。

他说，该公司预计，到2019年投产的油井，其平均侧向长度将从2018年的7500英尺左右增加到1万英尺以上。

Southwestern Energy to focus on Appalachian gas, liquids, after exiting Fayetteville shale

With the sale of its Fayetteville shale assets late last year, Southwestern Energy plans to sharpen its focus on the Appalachian Basin, balancing its drilling efforts between its extensive dry-gas and liquid-rich acreage, company officials said Friday.

In its release of its fourth-quarter and full-year 2018 results, the producer reported that in 2018 it grew its total Appalachia production by 21% to 702 Bcf-equivalent (1.92 Bcfe/d) year on year, while its liquids production grew 40% to 63,100 b/d.

The company reported total production, adjusted for the Fayetteville asset sale in December, of 946 Bcfe (2.59 Bcfe/d) for the year.

"We have an extensive portfolio of high-quality acreage with multiple benches and a deep inventory of high-value investment opportunities, both in natural gas liquids and in natural gas," President and CEO Bill Way said in a conference call with analysts.

Company officials said that last year Southwestern improved its well performance and operational efficiencies through the use of techniques such as the drilling of extended-length laterals.

"We drilled three laterals over 15,000-foot each, one being the company record of almost 16,200 feet, and all three of these wells were on time and on budget," Executive Vice President and Chief Operating Officer Clayton Carrell said on the conference call.

Going forward, he said the producer would continue to test ultra-long laterals in 2019, pointing to an 18,000-foot lateral Southwestern drilled last month in West Virginia.

The operator expects to see average lateral lengths rise from about 7,500 feet in 2018 to more than 10,000-foot on wells brought online in 2019, he said.
