Guadalupe County · Darst Creek (Buda) field · Shut In · Horizontal
Knobloch C. #1H (API 42-187-33420) is a horizontal well in Guadalupe County operated by Texas Petroleum Investment CO., completed August 11, 1993 and listed as shut in on the RRC schedule, shut in January 1, 1998.
The RRC has issued one drilling permit, issued June 29, 1993, permitted to 2,361 ft.
It was permitted by Meridian Oil Production Inc. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.

Its lease has reported 74K barrels of oil and 11.3K mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 16 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
