我们这家石油勘探公司开支巨大，原来一直在放弃勘探的边缘徘徊，直到上周我们的一口钻井打出了石油。
EXAMPLE: Our petroleum exploration company's expenses were huge, and we were tottering on the brink of abandoning our efforts until last week when one of our drills discovered oil.
钻井成本比预期的下降速度慢一些，上个月先锋公司公布了2016年产量增加目标，但是并没有增加开支。
The cost declines are expected to slow, but Pioneer last month lifted its 2016 target for production growth without any spending increase.
