A recently drilled Eagle Ford well was completed with a propane frack. eCorp Stimulation Technologies successfully stimulated an Eagle Ford well at 5,950 ft in Frio County, TX. The completion is part of the company’s efforts to minimize water usage in well completions. The test was done in December 2012 just south of Pearsall, TX. Pure liquid propane was used, with no chemicals or additives [Read more…]
Jadela’s El Indio #1-H Eagle Ford well that was completed with a GasFrac propane frack or LPG frack was tested over the past couple of weeks. The companies injected over 225,000 gallons of liquid propane and butane into the formation. The well test results are a little difficult to interpret because production was limited by the LPG fluid recovery system. The most recent 24 hr period produced 210 barrels of oil and 706 mcf. It’s still early to declare success, but those aren’t bad numbers for Maverick County, TX.
It will be interesting to see just how much propane and butane Jadela was able to recover. LPG’s are expensive frack fluids, but you get to resale the fluid if it can be recovered. [Read more…]
Eagle Ford completion technology is evolving as it needs to if operators want to remain competitive. Operators have lots of theories, but the proof is in the pudding. Drilling and completing wells is the only real way to test new technologies. That technology is needed as we experience rising service costs, along with natural gas prices of $4 per mcf and oil prices that look to be below $90 for the foreseeable future. $90 a barrel isn’t bad, but it isn’t $100.
Petrohawk was the first to announce a major change in completion technology by using Schlumberger’s Hi-way Frac system. SLB refers to it as “HiWay Flow Channel Fracturing”. Fancy name and all, nobody really cares unless it delivers. For Petrohawk, it looks to have done just that. Petrohawk had utilized hiway fracs in 12 wells that had a production history of 90 days or more as of June. Those 12 wells had produced 32% more at a pressure 42% higher than other wells with a choke (18/64ths). More production at a higher pressure is about as good as it gets. The higher pressure indicates better overall communication, which is great in tight shale rocks. We’ll hear more about hiway fracs as operators test it in other parts of the Eagle Ford and in other plays. Read more on Schlumberger’s HiWay Flow Channel Fracturing at www.slb.com [Read more…]
A propane frack or LPG frack was completed yesterday by Jedela Oil Corp in conjunction with Gasfrac and Packers Plus in the Eagle Ford Shale of Maverick County, TX. Watch for results from this well as it will be an early indicator of whether or not propane fracks can provide upside to current economics in the Eagle Ford Shale. LPG (liquified petroleum gas) or propane fracks will also gain more interest if the drought continues in South Texas. In a few cases, we’ve heard of operators drilling $500,000+ water wells to ensure delivery of hydraulic fracturing fluids.
While the process is often referred to as a “propane frack”, an “LPG Frack” is more correct. The fluid is usually more than 90% propane, but will include ethane, propylene, butane, and some heavier hydrocarbons. A few of the benefits of LPG fracks versus hydraulic fracturing completions include:
- LPG’s are more compatible with the formation’s gas
- Quicker completions, with no flow back water
- Reduced formation damage
- Costs savings where water isn’t abundant [Read more…]
