In the 1980s and early part of the 1990s, Ashland continued to expand, buying The Permian Corporation and merging it with Scurlock Oil Company in 1991 to form a subsidiary known as Scurlock Permian Corporation.
Компания The Permian Corporation, которая объединилась с нефтяной компаний Scurlock в 1991 году, образовала дочернюю копанию Scurlock Permian Corporation.
