The Eagle Ford Shale Play of south Texas is the site of massive oil and gas investment and activity. Basic statistics of the play are listed below in comparison to similar stats for the Bakken Play. Both states boast that their oil play is the biggest and busiest but no clear winner is in sight. Both are huge plays where billions of dollars are being spent and millions of barrels of oil being produced.

June 24, 2013

While the SWDI Blog usually deals directly with salt water disposal wells, today’s topic swirls around all aspects of the water management business. The blog post emphasizes the importance of controlling waste salt water in the oilfield to reduce environmental damage and financial liabilities.

Apache Oil Canada’s pipeline break (June 2013) resulted in a produced water spill equivalent to 500 water trucks in Alberta bog land!

Measurements for volume of salt water have been converted to barrels for the remainder of this blog post. The Zama City, Alberta, spill is estimated at 9480 cubic meters which equals 59, 627 barrels (or 497 water trucks).

A produced water spill, the equivalent of 500 water truckloads, that occurred around June 1, 2013, in… Continue reading

Thousands of new oil wells mean more waste water must be managed in a safe manner.

Horizontal drilling of the Bakken/Three Forks has been in high gear for over ten years. These low-permeability (tite-oil) reservoirs can only be economically accessed by long horizontal wells and high-pressure/high-volume fracture treatments. The fracture treatment is vital to well economics but the placement of the well is also important – there are geological “sweet-spots” in the large reservoir. Once the appropriate completion technique is applied, the new well produces at very high rates and operators can make their investments back in a matter of months rather than years. The Bakken play is still… Continue reading
