The Grayson Mill Pyramid Wells, Northwest Side Of Williston, Todd Oil Field

Locator46487GM.

During the boom, Brigham drilled four Pyramid wells on the northwest side of Williston. The pad remained unchanged for quite some time while the city of Williston grew and surrounded this pad, including the new Williston High School and I pretty much forgot about the Pyramid wells. Today, I noted that these wells have been acquired by Grayson Mill and Grayson Mill now has six more locations "on" the same pad:

  • 35866, loc, Grayson Mill/Equinor, Hawkeye 16-21 8H (original, 8TFH), Todd,
  • 35867, loc, Grayson Mill/Equinor, Pyramid 15-22 XWW 1H, Todd,
  • 35868, loc, Grayson Mill/Equinor, Pyramid 15-22 6H (original, 6TFH), Todd,
  • 35869, loc, Grayson Mill/Equinor, Pyramid 15-22 5H, Todd,
  • 35870, loc, Grayson Mill/Equinor, Pyramid 15-22 7TFH, Todd,
  • 35871, loc, Grayson Mill/Equinor, Pyramid 15-22 8TFH, Todd,

All six horizontals will run parallel, north to south, and all will end in section 22 to the south, except #35866, which will end in section 21 to the south, and to the west of section 22.

The production data for the wells have been updated.
