Carrizo Plans Pearsall Shale Test - Added 2,000 Acres in Q3

Carrizo Eagle Ford and Pearsall Shale Map
Carrizo Eagle Ford and Pearsall Shale Map

Carrizo Oil & Gas will test a Pearsall Shale well in late 2012. The Eagle Ford Shale is the company's primary focus in Frio, La Salle, McMullen, and Atascosa counties, but the Pearsall could add additional resource to the company's portfolio. The first test will spud in late November 2012 in Frio County. Just a couple of weeks ago, Cabot Reported Pearsall Shale Well Results that looked promising. Carrizo is following suit.

Carizzo also added 2,000 acres in La Salle County during the third quarter of 2012. The company now has more than 48,000 net acres prospective for the Eagle Ford. That acreage is predominately located in La Salle County, but stretches across three neighboring counties as well. The Pearsall is prospective on 30,000+ acres of the company's position, but it will take several exploration wells before the company knows where the play has liquids potential. Dry gas wells aren't going to be the target if natural gas prices stay low. [ic-c]

Carrizo's Eagle Ford Assets Continue Growth Trajectory

At the end of the third quarter, Carrizo was producing 7,200 b/d and 14 mmcfd net. The company is producing from 61 gross wells and has three rigs running continuously. 24 gross (19 net) wells are waiting to be brought to production. Four 80-acre spacing wells have been tested, but more production history is needed before the company can deem the down spacing test successful.

The company's first 45 wells averaged 530 b/d of production through the first 30 days. IP rates are coming in consistently in the 600-1,000 barrel range and EURs are estimated at approximately 400,000 boe per well.  Oil production is also enjoying premiums of as much as $8 to NYMEX quoted prices. Watch for conclusive results on down spacing and production from the first Pearsall Test.

EOG Resources' Monster Wells Are Getting Bigger

EOG Resources' monster Eagle Ford wells are getting bigger! The company brought one of its best producing wells to date in the third quarter of 2012. The Baker-DeForest Unit #4H tested at 4,598 b/d of oil and 4 mmcfd of rich natural gas at normal choke rates. At LLS oil prices, the well is yielding gross revenue of almost $500,000 per day! It doesn't matter what the decline curve looks like. A well like this will potentially pay back in the first month of production. It's a boon for mineral owners too. The well will pay between $50,000-$100,000 per day to royalty owners. You can read more about the company's biggest well here: EOG Reports Record Eagle Ford Well.

In Gonzales County, the Baker-DeForest Unit #4H came on line at 4,598 barrels of oil per day (Bopd) with 488 barrels per day (Bpd) of natural gas liquids (NGLs) and 2.9 million cubic feet per day (MMcfd) of natural gas. The Baker-DeForest Unit #1H, #2H, #3H and #12H were turned to sales at initial rates ranging from 3,346 to 4,216 Bopd with 457 to 537 Bpd of NGLs and 2.7 to 3.2 MMcfd of natural gas. EOG has 100 percent working interest in these five Baker-DeForest wells.

EOG's monster wells are are defined by the company as having initial production rates of 2,500-4,800 barrels of oil production per day plus natural gas and NGLs. The company completed 16 monster wells in the second quarter of 2012 and brought on 12 more in the third quarter.

EOG's Eagle Drilling Cost is Falling

EOG's average well costs in the play are falling near $5.5 million as the company realizes the benefits of sourcing its own frac sand, improving service costs, and increased operational efficiencies.

The company's average drill time has fallen to 13 days per well. That means a lot of wells can be drilled with 20 rigs active. EOG will drill 320 net wells in 2012 alone.

EOG Operations Expand Across South Texas

EOG's production eclipsed 109,000 boe/d in the quarter - 75% oil, 13% NGLs, and 12% natural gas. The play has been the biggest driver of crude oil production growth across the company's portfolio. The four main takeaways from the company's Eagle Ford update were:

  • Monster Wells are improving – 16 wells came online with IPs between 2,500 and 4,800 b/d of oil
  • Th company continues to test multi-well pilots at denser spacing (65-90 acres)
  • Oil is being priced at LLS, which is trading at a premium to WTI
  • Average well costs are falling near $5.5 million
  • 20 rigs are expected to drill 320 net wells in 2012, with an average drilling time that has decreased to 13 days per well.

EOG also completed notable wells in McMullen County and La Salle County:

  • In McMullen County, the Lowe Pasture #9H and #10H produced at initial production rates of 1,905 and 2,075 b/d oil, 112 and 115 b/d NGLs, and 673 and 688 mcfd of natural gas
  • In La Salle County, the Martindale L&C #1H and #2H came online at 1,522 and 1,876 b/d oil, 220 and 208 b/d NGLs and 1.3 and 1.2 mmcfd of natural gas

Near the DeWitt County line in Gonzales County EOG reported the following:

Reilly Unit #1H had an initial oil production rate of 3,579 Bopd with 483 Bpd of NGLs and 2.9 MMcfd of natural gas. EOG has 70 percent working interest in this well. Also in the new area northeast of the Reilly, the Boysen Unit #1H and Baird Heirs Unit #4H were completed at 2,540 and 2,242 Bopd with 268 and 181 Bpd of NGLs and 1.6 and 1.1 MMcfd of natural gas, respectively. EOG has 100 percent working interest in both wells. EOG also has 100 percent working interest in the Henkhaus Unit #8H, which was completed offsetting the previously drilled Henkhaus Unit #10H and #11H. The #8H had an initial production rate of 4,012 Bopd with 495 Bpd of NGLs and 3.0 MMcfd of natural gas.

Marathon Oil Brings on Record Well - Drilling 255 Eagle Ford Wells in 2012

Marathon Oil reported earnings today and impressive Eagle Ford results accompanied the news. Marathon has driven Eagle Ford drilling times down to 24 days across its acreage and has increased the number of wells it expects to drill by 20 to 250-260 in 2012.

"Our investment in the Eagle Ford shale a little more than a year ago, and our bolt-on acquisitions since then, continue to deliver value beyond original expectations. Not only have we improved the speed and efficiency of our drilling and completions there, we also continue to optimize well spacing which could significantly increase drillable locations and recoverable reserves.

Marathon's Record Well

In the quarter, Marathon drilled 78 wells and brought 73 to production. With one of those completions, Marathon brought on a well that came close to EOG's Record Eagle Ford Well. The Burrow 2-H in Gonzales County produced at a peak 24-hour rate of 6,275 boe/d. Almost 75% (4,646 boe) was attributable to oil and condensate.

The record well contributed to impressive production growth too. Production in the third quarter averaged approximately 40,000 net boe/d - 33,000 b/d of liquids and 46 mmcfd of natural gas. That's up from 18,000 b/d and 18 mmcfd in the second quarter. As of November, production had reached 60,000 net boe/d, a 50% increased from the third quarter average!

Marathon also closed a previously announced deal for 4,300 net acres in South Texas for $232 million. The deal added 40 net drilling locations and 2,900 boe/d of production.

Chesapeake Selling Eagle Ford Acreage in the Northern Block

Chesapeake's Eagle Ford Northern Block
Chesapeake's Eagle Ford Northern Block

Chesapeake's Eagle Ford assets will be trimmed down as the company's focuses on its core areas of development. As part of the company's "core of the core" strategy, they will divest areas of the Eagle Ford that might not be held by production as leases expire. Chesapeake is simply capital constrained.

The CEO Aubrey McClendon put it best:

"We’re long assets and short capital"

Chesapeake is selling Eagle Ford assets to create cash flow for ongoing development. The company simply doesn't have the money needed to develop all of its acreage across the U.S. As you would expect, the company is rationalizing all of its assets and focusing development in areas offering the highest returns.

The company calls the area for sale its "Northern Block", where the Eagle Ford is largely an oil producing formation. The majority of acreage in the Northern Block is located in Zavala County. Production associated with the area currently amounts to 10,000-11,000 boe/d. The company expects to close the deal by the end of the year and its should be an attractive acreage position. There's a rough outline of what might be sold in the image above. Especially if the Pearsall proves to have liquids potential across portions of the acreage.

Chesapeake Third Quarter Eagle Ford Highlights

While they're selling a portion of their acreage, the company continues to impress operationally. Highlights from their quarterly earnings release include:

  • 120,500 gross (52,200 net) boe/d of production; Up 371% year over year and 44% sequentially
  • Production is 68% oil, 14% NGLs, and 18% natural gas
  • 124 wells reached first production during the quarter
  • 233 wells have been drilled, but are not yet producing
  • Will exit the year with 22 rigs, down from 34 at its peak
  • 93% of wells brought online in Q3 produced more than 500 boe/d and 35% produced more than 1,000 boe/d
  • Three wells highlighted during the quarter came online at rates between 1,600 and almost 2,200 boe/d.

Eagle Ford Regional Rig Count at 269 - Nov 2, 2012

Cabot Oil and Gas Pearsall Shale Target Area Map
Cabot Oil and Gas Pearsall Shale Target Area Map

Eagle Ford Shale drilling four rigs to settle at 269 working over the past week. Through the first ten months of the year, more than 270 rigs have worked the 30 county area we track where there is Eagle Ford development potential. That's roughly 25% higher than the rig count average in 2011 a.nd right in line with current activity levels

This past week was highlighted by earnings reports. Cabot announced results from its first Pearsall Shale well in Frio County. The well produced 1,400 boe/d at its peak, with 50% of production attributable to oil. That's a decent oil well for what most have targeted as a gas play historically. Cabot's Pearsall acreage and the area where operators are testing the play is highlighted in the exhibit above.

Eagle Ford Oil & Gas Rigs

The natural gas rig count has grown to 55 rigs since hitting a low of 38 at the beginning of October. Natural gas prices broke through the $3 barrier last month, so it's no surprise operators are taking this opportunity to develop gas prone areas. Henry Hub futures were up to $3.55 to end the week.

The oil rig count fell six rigs to 213 running during the week. Just one service well is currently being drilled and it is a water well in Bastrop County. This well has been drilling for several weeks. If anyone has checked on the permit, please share the details in the comment section below.

WTI was down to just under $85 per barrel on Friday. The price fluctuated quite a bit during the week as a larger than expected storage draw supported prices, but a weaker than expected jobs number hit prices on Friday. Eagle Ford crude priced at $96.2/bbl on the 2nd of November. Light crude and condensate in the area traded at $81.25 and $80.25, respectively.

There are 256 horizontal rigs running in the region. La Salle County leads development with 37 rigs running. Karnes with 35 rigs, McMullen (28), Webb (26), Dimmit (22), Gonzales (22), DeWitt (17), Live Oak (13), Atascosa (11), and Fayette (8) round out the top Eagle Ford counties.
