A shale formation with sandstone interbedded is also a potential oil bearing formation.───以泥岩为主，夹砂岩的地层也可能是油气层。

Horizontal maximum and minimum principal stresses are nearly equal in shale formation, and very different in sand formation.───在泥岩段水平最大与最小主应力基本相等或相差甚小，在砂岩段才呈现较大差异。

There are many factors to affect identification of oil and gas bearing layers in the sand-shale formation.───在砂泥岩地层中，影响油、气层识别的因素较多，尤其在复杂地质条件下准确识别油气层难度更大。

Statoil could be an attractive partner because of its experience developing the big Marcellus Shale formation in the US north-east.───由于在美国东北部开发大型马塞卢斯页岩（MarcellusShale）层的经验，挪威国家石油公司可能是一家有吸引力的合作伙伴。

Two-step approximate formula of seismic velocity in sand and shale formation is given on the basis of core analysis. logging data interpretation and wave velocity mechanism analysis.

A clutch of roughnecks, smudged with dirt and tattoos, are coring the earth, bringing up a little slice from the shale formation below.
