Texas RRC Report and Other Peak Oil News

Ron Patterson 499 Comments

The Texas Rail Road Commission has released its latest stats with production numbers through January. There is always a delay in these numbers and that is why you see the production graph lines seem to droop toward the recent months. Because of this I post six months data so the data can be compared in order to gain a better insight into which way production is heading.

All Texas oil and gas data is through January. The Oil data is in barrels per day and the gas data is in MCF.

Texas Condensate

Texas condensate will likely show a small gain when the data is finally in. Either way it will not be enough to make much difference in the final C+C January production.

Texas Crude Only

I believe Texas crude only will be down in January. This shows a huge decline from the December incomplete data. The EIA data is through December only.

Bakken and North Dakota Production Report

Ron Patterson 441 Comments

The North Dakota Industrial Commission just published their Bakken Monthly Oil Production Statistics and also their ND Monthly Oil Production Statistics.

Bakken Barrels Per Day 2

Bakken production was down 1,598 barrels per day to 1,118,010 bpd. All North Dakota production was down 4,054 bpd to 1,182,174 bpd.

From the Director’s Cut, bold mine:

The drilling rig count dropped 2 from September to October, an additional 3 from October to November, and has since fallen 5 more from November to today. The number of well completions decreased from 193(final) in September to 134(preliminary) in October. Three significant forces are driving the slow-down: oil price, flaring reduction, and oil conditioning. Several operators have reported postponing completion work to achieve the NDIC gas capture goals. There were no major precipitation events, but there were 9 days with wind speeds in excess of 35 mph (too high for completion work).

The drillers outpaced completion crews in October. At the end of October there were about 650 wells waiting on completion services, an increase of 40.

Crude oil take away capacity is expected to remain adequate as long as rail deliveries to coastal refineries keep growing.

Rig count in the Williston Basin is set to fall rapidly during the first quarter of 2015. Utilization rate for rigs capable of 20,000+ feet is currently about 90%, and for shallow well rigs (7,000 feet or less) about 60%.

Sep rig count 193
Oct rig count 191
Nov rig count 188
Today’s rig count is 183

Sep Sweet Crude Price = $74.85/barrel
Oct Sweet Crude Price = $68.94/barrel
Nov Sweet Crude Price = $60.61/barrel
Today Sweet Crude Price = $41.75/barrel (lowest since March 2009)

I just checked Rig Count. It now stands at 181 but one of them is drilling a salt water disposal well. So they have 180 rigs drilling for oil right now.

Bakken Wells Producing

Bakken wells producing increased by 118 to 8,602 while North Dakota wells producing increased by 92 to 11,507. Since Bakken wells are included in the North Dakota count this means at least 26 wells outside the Bakken had to be shut down.

More on Bakken Production, Choke Theory

Ron Patterson 308 Comments

The US Petroleum Supply Monthly just came out with production data for every state and territory. US supply was up 168,000 bpd to 8,864,000 bpd in September. The biggest gainers were North Dakota, up 53,000 bpd to 1,185,000 bpd and Alaska up 79,000 to 477,000 bpd. Alaska  was way down in both July and August and are just recovering from that.  There was only one big loser, New Mexico, down 18,000 bpd. Texas was up only 9,000 barrels per day which was surprising. The Gulf of Mexico was down 3,000 bpd.

The Choke theory and why I ain’t buying it.

North Dakota publishes a Daily Activity Report Index of all permits and other well activity in the Bakken as well as the rest of North Dakota. In this report is a list of all producing wells completed as well as wells released from confidential (tight hole) status. Wells usually stay on this list from a few days to a few months, but the average is only a few weeks.

I have collected this data from October 2013 to present and found some startling results. But some have said this data means nothing, that wells are usually choked off by the driller so therefore we can gain nothing from the data. But looking at the individual wells that just doesn’t make any sense. No, I agree that the driller chokes but that he would not gradually choke more according to increasing well number.

Below I have posted the first 24 hour data for all 122 wells reported by North Dakota for the first 25 days of November. The first 24 hour production ranges from over 3000 barrels of oil per day to a low of only 10 barrels of oil per day. Barrels of water range from a high of 6663  bwpd to a low of 48 bwpd. And the percent water cut ranges form a high of 94.15% water to a low of 12.75% water.

It just seems incredible to me to claim that these numbers are meaningless. Throughout all the almost 14 months of data I have gathered there are lots of very large producing wells and a lot of small producing wells. The point is as the well number increases the number of very large producing wells seems to decrease while the number of small producing wells seems to increase. And I just don’t believe this is due to the many drillers, after checking their well number, decides what size choke to apply.

Just below the list of all wells I have averaged the production according to well number. The sample however is not large enough to really mean a lot. The number of wells in the sample are: Below 26000, 11 wells  – 26000s 35 wellw – 27000s 54 wells – 28000s 23 wells.

Bakken Sweet Spots are Petering Out

Ron Patterson 420 Comments

The Bakken, as well as other shale oil areas, is not one homogeneous area where equal amounts of can be found. David Hughes in DRILLING DEEPER puts it this way, though here he is talking about gas wells, the same applies to oil wells:

All shale gas plays invariably have “core” areas or “sweet spots”, where individual well production is highest and hence the economics are best. Sweet spots are targeted and drilled off early in a play’s lifecycle, leaving lesser quality rock to be drilled as the play matures (requiring higher gas prices to be economic); thus the number of wells required to offset field decline inevitably increases with time.

However the Bakken, at least through the September North Dakota Industrial Commission  production report, has given no real indication that the Bakken is even close to peaking. But a closer look at the data makes me believe that is all about to change.

The NDIC issues a Daily Activity Report where they list permits issued as well as wells completed and wells released from the tight hole confidential list. These reports usually, but not always, also give the number of barrels of oil per day and barrels of water per day for the first 24 hours of production.  I have gone through every day, back to November 1st, 2013 and collected the data on every well listed that gives production numbers and copied that data to Excel. In that one year and three weeks I have gathered the data form every one of the 2,171 wells that give production numbers. Sorting these wells by well number, which is the original permit number, gives some startling results.

ND 200 Well Avg

To smooth the chart I created a 200 well average of barrels per day per well. The first point on the chart is therefore the average to the 200th well, #23890 and the last point is the 200 well average to the 2171st well, #28971. As you can see there has been a continuous, though erratic, decline in first 24 hour production as the well numbers increase.

ND Prod per 1000

Breaking this down according to well numbers we see production peaked with the 2400s and have steady decline since. Every group of well numbers do not contain the same number of wells.
