Reading well data on Sonris, I've noticed that some wells have a production casing of 4&1/2 inches; and others have 5&1/2 inches. With the well depths being very close (give or take 500 feet), why the difference in casing. Anyone have an answer? Thanks in advance.
Jim Krow... can you tell me why some wells are using 7" casing? ? Does this have anything to do with drilling horizontal or is there a definate reason for using 7" Thanks.
