< p >他们显微镜下检查钻碎片,确定它们是否在目标的形成,通常珊瑚/海洋贝壳。这不是完成所有井但对探索性和失步井(扩大字段)。主要兴趣是气/油比、烃/水比、硫水平。年龄仅仅是感兴趣的,因为它给了其他属性的信息。他们有一个好主意的形成和年龄之前就开始钻井。探索性和填入井将不同的处理。Drillers may refer to infill wells as "post holes". I have been retired for awhile but a lot of progress was/is being made in "measurement while drilling " so they know where the bits are and where it is going in real time so microscopic exam may no longer be as important
