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

The company is touting the well as a "success", but we'll have to watch flow rates to see if the well is successful from an economic standpoint.

Dr. John Thrash , eCORP's CEO and Chairman, stated, "We are extremely pleased with what we have confirmed with this procedure. We believe there is a certain path for sustainable shale gas development and this demonstration proves a viable "green" alternative exists for stimulating shale. We intend to extend this design philosophy and demonstrate that a total reduced impact can be achieved through other innovations in drilling and exploration technologies we are developing at eCORP."

LPGfracks will be interesting to watch across the shale plays. Using fluids native to the formation seems logical, but they're also much more expensive than water. This isn't the first well in the Eagle Ford completed in this fashion - Jadel Oil completed a well with an LPG frack in Maverick County back in 2011. Blackbrush Energy also has an exclusive agreement with Gasfrac Energy Services to complete its wells with LPGs through mid-2014.

Jadela - GasFrac’s Eagle Ford El Indio #1-H Propane Frack Test

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.

Jadela Oil Corp. wishes to announce that the El Indio #1-H well produces oil, gas, butane and other hydrocarbons. Approximately 5,360 barrels of liquid propane/butane were injected into the formation to fracture the well. The majority of this propane/butane is expected to be recovered and resold or used for fracturing subsequent wells. The well was flowed for 58.75 hours from August 27, 2011 to August 31, 2011. The well was then shut in in order to test the purity of the recovered propane/butane for resale purposes. The well was reopened on September 3, 2011 and is currently producing. The well is expected to be produced for the next 7 to 10 days while the tie-in pipeline and permanent treatment facility, storage tanks and trucking terminal are being constructed.

The permanent treatment facility/trucking terminal is located two miles away from the El Indio #1-H wellsite on Highway 1021. Oil flow and gas flow are restricted by the capacity of the propane/butane recovery equipment. As of September 6, 2011 (6:00am)(122.75 flowing hours) the well had produced 969 bbl of oil (210 bbl in last 24 recorded hours) and gas of 13.978 MMscf (0.706 MMscf in last 24 recorded hours) or alternatively stated a boe/d of approximately 327 boe/d (for last 24 recorded hours) from a 2,400 foot lateral with an 8 stage frac (2 of which were not fully fracced) with the flow rate choke restricted to 10/64 of an inch. The oil recovery rate is increasing as the propane/butane from the frac is recovered. Jadela is in the process of acquiring additional equipment to increase the propane recovery rate.

When drilling El Indio #1-H, Jadela drilled a pilot hole and logged the pilot hole with the following log suites: DSL/HDIL/ZDL/CN/GR/Sonic. A total of 25 sidewall cores were obtained over the 186 foot Lower Eagleford formation. In the El Indio #1-H wellpath/frac zone (excluding certain anomalous results) the lab results as prepared by Core Laboratories LP (independent laboratories) showed TOC of 5.0 - 6.5% with a carbonate percentage of 50 - 60%. Total (ambient) porosity (MR Shale TM Analysis - Core Laboratories LP) ranged from 10 - 15% and total percentage pore volume occupied by oil ranges from 37% to 79%. The oil produced has an API gravity of 40.3 degrees according to Fesco, Ltd (independent engineers).

Eagle Ford Oil & Gas Completion Technology - HAL - SLB - GFS.TO

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 [ic-c] The other service companies are not slouches, and are working the technology game too. Halliburton is pushing for speed and has lowered completion times by as much as two days with its "Delta Stim" completion service. Multiply two days per well over 100s of wells per year and you begin saving alot of money. Across 182 wells per year, that's an extra well on production for a full year! Days and hours count in the oil & gas game. If you're offering, I'd be just fine with an extra year of production from an Eagle Ford well.

A GasFrac completion in Maverick County is being tested for Jedela Operating. The results will be interesting to watch as GasFrac's technology is more commonly used in Canada where the company was founded. The idea is interesting. If you can sell your flowback fluids or gas, you might only be out the costs of getting it there. If you're in a drought and have to spend top dollar for water, it gets even more compelling. If better production rates and quicker completions prove true, you'll likely end up with a winning combination. Read more at GasFrac.com.


Propane Frack Test in Maverick County - Jadela, Gasfrac, Packers Plus

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

Jadela Oil Corp. (CA:JOC), GASFRAC Energy Services Inc. (CA:GFS) and Packers Plus Energy Services Inc. are pleased to announce that on August 21, 2011, Jadela completed fraccing its El Indio #1-H well into the Eagle Ford shale formation on its property located in Maverick County, Texas. Jadela used a Packers Plus StackFRAC(R) Open Hole Multi-Stage completion liner system and fracced the well using propane/butane and sand instead of water. GASFRAC provided the pumping horsepower and its stimulation technology in conjunction with Jadela's operational expertise.

Jadela has not tested the well. Testing will occur this week and it is expected that the well will be shut in pending construction of the propane recycling equipment and well site facilities. Jadela is in the process of outsourcing the construction of a pipeline, permanent battery equipment and the pipeline hookup to a 6" inch pipeline close by operated by West Texas Gas. The well was drilled and completed on a "tight hole" basis and as such specific well information is not available to the public at this time.
