Artificial Lift in the Utica

I've seen the stories about needing "nodding donkeys" but does anyone who works in industry have a feel as to what has been tried, what it working (or isn't). ESP's, gas llift?

Thinking that if a 2nd vertical at the end of the horizontal were developed; and if the horizontal were sloped down toward the 2nd vertical (to provide gravity drainage of the horizontal toward the 2nd vertical) and then a sump / reservoir also developed at their intersection; no angle (from vertical) would be necessary. What do you think ? Any merit ?

Brian,
Wondering also if these pumpjacks / nodding donkeys come with different
options / in different standard sizes / different configurations ?
Like varying sizes / counter weight (weights) / riser diameters (pipe sizes) / electric motor horsepowers, etc. ?
Seems like they would have to be customized for each application.
Also, are their motors always electric ? Or are there gasoline / natural gas models (perhaps using natural gas from the well for fuel) ?

Joe,  you should see the pumpjack on the well off Little Indian rd. off st.rt. 658 near Birds Run. LARGE!  You can drive up close to it.  And yes, I just read an article recently about powering these and other well site engines with the natural gas from the well.  saves $$$.

Years ago in the oilfields they used Hemi engines on pumps and quite a few were scavenged for use in drag racers when they became scarce in wrecking yards.

A picture wouldn't do it justice,since there is a gate blocking entrance to it.  about 100yds. away.  If you could get a pic with a person standing beside it, then you could tell it's real size.

Read an article yesterday about a coal plant they are building in Mississippi. They will be extracting the CO from the exit gas, turning it to a liquid form, and selling it to O&G companies to inject into wells to force the oil out.

WLW-

did the article you read mention carbon monoxide(CO) or carbon dioxide (CO2)?  Big difference there. Carbon dioxide flooding for improved recovery has been done for decades in West Texas and elsewhere, more typically in conventional reservoir types(interconnected pore throats, much higher permeability, etc.). I'm a skeptic that this type of improved recovery would be feasible in the Marcellus, and I have huge concerns about casing corrosion and other issues.

using co2 would be feasible in a formation like the clinton sandstone not in a gas formation like the marcellus or utica  also the big indian or berea is a formation  in this area for use of co2 ......co2 is used as a vehicle to move oil not natural gas

When you do CO2 flooding you have to make sure all the casing is stainless steel. Very expensive but if you don't the C02 combines with brine water in the formation to create carbonic acid, which then corrodes the casing. Some companies in the eagle ford are injecting dry gas into the shale (where it's oil/condensate) and enhancing the ultimate recovery of their horizontal wells by using the gas to sweep the liquids. Should work in the Utica/liquids rich Marcellus....

i know of no wells that have stainless steel casing but the oil companies are using co2 in many areas  i dont think they be using it if the co2 and brine was going to eat the pipe up it be a stupid move on their part .....and i never scene any stainless steel tubing either and i worked on almost every well in the ohio east canton field ......i steamed pipe on just about every well between erie pa and cambridge ohio some 2 or 3 times in 10 years 1975 to 1985 ........my company was  STEAM KING .........AND THE MARCELLUS HAS PLENTY OF GAS PRESSURE BEING SO NEW THAT THEY WOULD NOT NEED TO WORRY ABOUT SECONDARY RECOVERY AT THIS TIME ....CO2 IS FOR USE IN OLD PLAYS THAT THE GAS HAS BEEN EXHAUSTED AND THE PRESSURE IS LOW ..... and the oil companies cant replace the casing .......at stainless steel prices they never recover the cost either  just for tubing .....i know of no steel companies producing stainless casing or tubing for wells ....everything i ever seen was standard black pipe .........if u know of any wells with stainless casing or tubing please tell me where they are .....i like to buy a few of them just to salvage the stainless at about 1000 bucks a ton
