FARMINGTON – The San Juan Basin could be headed toward a renaissance in natural-gas and oil drilling if rosy expectations touted by industry officials at Monday’s San Juan Basin Energy Conference hold true.

“In the southern part of the basin, the Mancos play has the potential to revitalize declining San Juan Basin oil production and also has a tremendous amount of future gas production in the northern part of the basin,” said Ron Broadhead, a principal petroleum geologist with the New Mexico Bureau of Geology and Mineral Resources.

The conference, which drew about 500 attendees from across the nation to San Juan College, was the first to have a dedicated focus on the Mancos Shale, which stretches across the northwestern part of New Mexico and into southwestern Colorado.

After years of declining production in the San Juan Basin, companies are eyeing the shale play for both natural-gas and oil potential because of advances in hydraulic fracturing and horizontal drilling technologies that have helped operators unlock shale gas and oil across the nation.

“It’s reasonable that the Mancos Shale could be a really, really good shale play in the San Juan Basin,” said Darryl Willis, the vice president of subsurface for BP North America Gas Exploration and Production Co.

Other presenters were more direct.

“I’m bullish on the Mancos, we’ve already seen a number of wells drilled that are economic,” said T. Greg Merrion, president of Merrion Oil and Gas. “I’m looking forward to this next boom.”

With natural-gas prices hanging around $4 per thousand cubic feet, many conference speakers focused on the oil-producing window of the shale play located in the southern San Juan Basin.

The play has been estimated to contain up to 60 billion barrels of oil, about 10 percent of which is expected to be recoverable, according to estimates by Encana and Daniel Fine, a senior energy analyst with the New Mexico Center for Energy Policy.

The possibility of a resurgence had some speakers proclaiming the beginning of a new era of economic prosperity for northwest New Mexico.

“These are happy times again,” former U.S. Senator Pete Domenici said.

If drilling does rev up in the area, La Plata County likely would see some spillover benefits.

Some New Mexico energy companies lodge prospective employees in Durango to show off the city as a regional amenity and a growing number of New Mexicans fly out of Durango-La Plata County Airport – both activities would likely increase with more natural-gas and oil activity, said Roger Zalneraitis, director of the La Plata Economic Development Alliance. A decade-long increase in commuters between Durango and Farmington also shows more people work in one place and live in the other.

“Our economies are more closely tied than people think,” Zalneraitis said.

Despite rosy predictions for Mancos Shale, production thus far from initial wells has been variable.

Of the 10 Encana wells drilled in 2012, “there’s some good stuff, some modest stuff and an area we haven’t really figured out yet,” said Jeff Balmer, the asset manager of the San Juan Basin for Encana Corporation.

Other industry executives stressed that they are still in the initial exploration stages.

“It’s still the early days for this play,” BP’s Williams said.

The newness of the shale play poses difficulties for regulators, said William Hoppe a district geologist with New Mexico’s Oil Conservation Division.

Because the basin varies so much geologically, it’s hard to create a single rule for it, Hoppe said.

With an eye toward the potential explosion of drilling, the Bureau of Land Management is undertaking new environmental-analysis projects and management plans related to future development, groundwater monitoring and air quality, BLM District Manager Dave Evans said.

Many gave a sense that the industry is breaking new ground with shale drilling in the area,

“What we call unconventional now is rapidly becoming conventional,” Broadhead said. “This is a new day for the industry.”
 
Industry hype is always nice. What do professional resource estimators like the USGS say is the amount? Conversely, what do the professional modelers and economists using the professionally based resource estimates (like EIA) say about this?
 
If it is a question between Government expertise regarding shale plays and the Industry as you propose! You would have to go with the Industry! It is not hype when Industry does all the drilling! and Industry understands the technology far better than EIA, USGS, EPA combined (not that EIA, USGS, EPA are not neeeded)! Government does not get it right often enough! Look how they screwed up Pavillion in Wyoming!
 
And on the Northern edge of the Mancos Shale Play in Colorado while the San Juan Basin Energy Conference (http://www.sanjuanbasinenergy) was into its second day this happened!


The Durango Herald 03/19/2013 | County agrees to shale-oil drilling
The national debate about shale drilling and hydraulic facturing played out Tuesday in La Plata County Courthouse as county commissioners considered signing a memorandum of understanding with a Texas energy company that has plans to drill two exploratory shale-oil wells in the southwest part of the county.

The wells will be the county’s first shale drilling.

After more than three hours of presentations and public comment, La Plata County Commissioners unanimously approved the memorandum of understanding with Swift Energy Operating LLC.

“This MOU does the best this county can do right now to protect the interests of the people who live in the area, to try to minimize the impacts on you and also allow energy development to go forward,” Commissioner Julie Westendorff said.

With the agreement, Swift will go forward to the Colorado Oil and Gas Conservation Commission with applications for two exploratory drilling and spacing units. The target is the Mancos Shale, a shale play that stretches across northwestern New Mexico and into Southwest Colorado and is thought to be rich in oil and natural gas.

The memorandum puts several requirements on Swift’s drilling operations, including emissions controls, water-sampling standards and well-pad sharing mandates, that go beyond what would be required by the state.

The county has made such agreements standard practice, and already has 22 memorandums of understanding with other operators in the county. The contract commissioners considered Tuesday is unique because horizontal hydraulic fracturing techniques used to unlock oil resources from the shale will have different and more intense effects on the county roads, water resources and surface landscape.

Multistage hydraulic fracturing requires at least three times the water required to drill coal-bed methane wells, for example, and shale-oil well-pad sites are about three times larger than those of coal-bed methane wells.

In response, the county added several components to the Swift memorandum that go above and beyond the standard contract for coal-bed methane operators. Those include groundwater sampling requirements that the COGCC adopted in January and will go into effect in May as well as a requirement that Swift do an assessment of all existing wells in the drilling units to make sure their operations won’t compromise the casing or cementing of those older wells.

At least 50 county residents packed the commissioners meeting room Tuesday to hear commissioners’ deliberations and share opinions about Swift’s project.

Many Fort Lewis Mesa residents cited concerns about the potential for fracking operations to contaminate groundwater in the area. Several people wanted more extensive water-well sampling requirements than those required by the Colorado Oil and Gas Conservation Commission, which require sampling of up to four wells within one half mile from the wellhead.

“I’m concerned the MOU is not enough,” resident Jessica Copp said. “We all deserve testing before, during and after (drilling) and probably at a larger distance from the well bore and the lateral.”

Swift will drill down 2,500 feet then extend its wells laterally for up to 3,000 feet said Bob Redweik, Swift’s corporate manager of health, safety and environment.

Copp and others also brought up the issue of truck traffic along the county roads and the potential for trucks to interfere with school buses, for example.

Swift likely will haul water, crude oil, fracking chemicals and produced water to and from the well sites, Redweik said. The company estimates the wells’ daily oil production will fill two 130-barrel capacity trucks, he said.

Other residents cited concerns about the risks fracking chemicals may pose to human health and the ecological effects of air pollution from drilling.

Swift also had its supporters who encouraged the county to approve the memorandum of understanding. Holding up drilling impedes on private property rights and hinders legal private contracts, said Mae Morley, a landowner who owns both land and mineral rights within the proposed drilling unit.

If Swift’s unit applications are approved at the state level, the company said it hopes to apply for a drilling permit in April and move a rig into the area this summer.

The Mancos Shale has edged more and more into the spotlight over the last three years, and the play was at the center of a two-day conference this week that drew about 500 people from around the nation to Farmington. However, most drilling into the shale has been done in the southern part of the San Juan Basin.

The prospects for oil in the northern part of the basin are still unknown, Redweik said.

“We’re trying to prove up something that hasn’t been done before,” he said.

Cool. Any information showing that this thing is actually bigger than the USGS assessment of the Bakken, or do these pump and dump press releases pass for actual information in your geologic opinion?
 
Ron Broadhead, State Geologist of New Mexico Spoke to a Sold Out audience at the San Juan Basin Energy Conference 3/18/13 (Home « San Juan Basin Energy) on the Mancos hybrid Shale play! Hybrid in the sense that the Mancos Shale contains both massive amounts of Oil and Natural Gas!

Mancos Shale (Cretaceous) in the San Juan Basin. The Mancos Shale in the San Juan Basin encompasses a shale gas play in the deeper northern part of the basin and an unconventional oil play from marine Mancos shales that are interlaminated and interbedded with marine shelf to slope sandstones in the southern part of the basin. This link will take you to a slide set developed for a presentation given to the The San Juan Basin Energy Conference on March 18, 2013. The slide set describes the geologic framework for the Mancos Shale oil play and the Mancos Shale gas play. A written report on the topic is in preparation.
