Drilling Down: The 10 longest horizontal wells in Texas by Sergio Chapa, December 16, 2019, chron.com
Most horizontal wells can be measured in feet but some of them can literally be measured in miles. In figures exclusive provided to the Houston Chronicle, Austin oilfield data company Enverus opened its vaults to reveal the 10 longest horizontal wells that have been drilled in Texas so far this year.
Drilling permits filed with the Railroad Commission of Texas, the state agency that regulates the oil and natural gas industry, reveal the total depth of a well — the combined length of its vertical and horizontal sections. But the Austin oil field data company Enverus took a deeper dive into hydraulic fracturing and completion filings to focus on the horizontal portions of a well to determine the 10 longest horizontal wells drilled in Texas this year.
Horizontal wells are best measured by their gross perforated intervals, the portion of the lateral that is hydraulically fractured using sand, water and chemicals. Enverus used filings submitted by operators to the Railroad Commission for its calculations. .
“This is a measure of horizontal part of the wellbore that is hydraulically fractured to produce oil and gas,” said Bernadette Johnson, Enverus vice president of strategic analytics. “This is the part of the well where the oil and gas flows from the surrounding rock. Perforated intervals have increased in recent years and resulted in wells with more production.”
The Permian Basin of West Texas dominated the list with eight of the 10 longest laterals. The Eagle Ford Shale of South Texas and Haynesville Shale of East Texas each had one.

Surge Energy, a Chinese-owned oil and natural gas company headquartered in Houston, drilled and completed the longest lateral in Texas so far this year.
A horizontal well on the Suege’s Medusa Unit C 28-09 lease in the Permian Basin’s Borden County measured nearly 17,000 feet, or about 3.2 miles. Completed in July, production figures for the lease are yet not available, but the company gets bragging rights for the longest horizontal well in Texas — at least for now.
