Horizontal Oil Wells Successful for Oryx

Article excerpt

By Jack Z. Smith Fort Worth Star-Telegram DALLAS - Oryx Energy Co. of Dallas says its much-ballyhooed horizontal oil wells in the Austin Chalk trend of southwest Texas are living up to their prior billing.

The Austin Chalk historically has been notorious for fickle oil and gas wells that are initially big producers but quickly play out.

But Oryx, in a hearing before the Texas Railroad Commission in Austin, said its Austin Chalk horizontal wells are showing sustained levels of high production.

Oryx presented statistical data on seven horizontal wells that showed the average well is producing more than 400 barrels of oil a day.

That rate is more than 40 times higher than the average Texas well, which produces about nine barrels of crude per day.

Oryx said cumulative production from the seven horizontal wells totals nearly 800,000 barrels. All the wells were drilled within the past three years. The average well has proved reserves estimated at 450,000 barrels, Oryx said.

As an example of the increased production realized from horizontal drilling, Oryx said one well W the J.B. Baggett No. 13 - has produced 206,000 barrels of oil in a period of sligtly more than two years.

In comparison, a well drilled by the conventional vertical method on the same lease as the J.B. Baggett No. 13 well has produced only 126,359 barrels over nine years, Oryx said.

Oryx presented the statistical data in contending that temporary Railroad Commission field rules for production from horizontal wells should be made permanent. The temporary rules provide for a fourfold increase in allowable production from a horizontal well - from 328 to 1,312 barrels of oil per day, with one well allowed per 320 acres. …
