McMullen County Eagle Ford Shale

Daybreak In The Oilfield

The break of dawn in the Eagle Ford Shale. A Lufkin pumpjack tirelessly pumps oil from a horizontal well south of Jourdanton Texas. The two main types of pumpjacks that you see in the Eagle Ford shale are Weatherford and Lufkin. Thanks in part to the South Texas oil boom, these two pumping unit manufacturers are having one of their best years. In a recent investor report, Lufkin industries reported the following: “Oilfield’s new order bookings increased 81% to $352.9 million from $195.3 million a year ago and were up 27% from $278.9 million in the prior quarter. The increase was mainly due to increased orders for automation and for new pumping units. Geographically, we saw the strongest bookings in the Bakken, Eagle Ford and Permian Basin in the U.S.”

Night Photos Of Pumpjacks In Eagle Ford

Below are some night photos of pumpjacks taken in South Texas. The following photo was achieved by taking a five minute exposure, and illuminating various parts of the pump jack during that time. This is a Weatherford pumpjack and it is operating on a portable generator. The most common brands of pumpjacks that you will see in the Eagle Ford shale are made by Weatherford and Lufkin. Millions of tons of steel are being used to build large pumpjacks such as these, which is a boost to the steel industry. Notice the orange glow that you see in the photos below. This is caused by “light pollution” from numerous H2S natural gas flares burning around McMullen County. These flares reduce the danger of poisonous hydrogen sulfide gas, as well as reduce the release of the greenhouse gas methane. Once famed for it’s dark skies and quiet nights, South Texas light pollution has increased dramatically over the past couple of years.

In terms of energy, there is a LOT going on in the photo below. Solar panels power small methanol and chemical pumps used to keep lines from clogging on the large pumpjack below. Overhead, large electric transmission lines deliver power to Laredo from a lignite coal plant near Christine, Texas. A flare in the background burns off waste H2S gas, and a glimpse of the portable generator running the pumpjack’s electric motor can be seen in the rear right of the photo. That’s a lot of energy all in one place!

Below is a photo of an older pumpjack on an abandoned Wilcox formation well, in McMullen County. This old pumping unit was powered by a single cylinder natural gas engine. Most of the new pumpjacks in the Eagle Ford shale are powered by electric motors. Many have not been hooked up to a permanent power source since electric lines have not been installed yet. Power companies are working as fast as they can to bring new electric lines to oilfield pumpjacks such as this one in the Eagle Ford Shale. All of the new electricity use in the Eagle Ford shale area is placing heavy demands on old power stations, such as Medina Electric’s power station in Pearsall, which will need to be expanded.
