Horizontal drilling and fracking are two distinct but related techniques:

  * "Horizontal drilling" refers to drilling a non-vertical
    (and often curved) borehole, to reach deposits that aren't
    directly beneath the wellhead.

  * Hydraulic Fracturing, "fracking," is the practice of injecting
    water into a well to crack the rock around the borehole,
    increasing its permeability.
Each can be used independently, but it's the combination of the two that has increased US production.

Yea you are correct, but are there any US Oil and gas producers horizontally drilling wells but not hydraulic fracturing the well?

I work in this industry. To answer your question, yes, there are oil and gas producers horizontally drilling wells, but not fracking them. This is actually quite common in offshore (Gulf of Mexico) environments. Your offshore pad is in a fixed location, and you often drill horizontally to get to the target.

These wells are productive enough that you don't need to hydraulically fracture them.

Yet. You left off the "yet".

curious, would fracking be used years or decades down the line to extend well life?

potentially, if it's economic enough. The typical shale wells that you see being drilled have very high initial rates, but then fall dramatically. They are a totally different well profile than the wells offshore (where shale is not being targeted).

Will shale ever be targeted offshore? Maybe, in a world where oil is $150/barrel and we're all still demanding it. A few things are holding back hydraulically fracking offshore:

1) Freshwater - The current "recipes" need freshwater, and do not work with salt water. Fracking uses a lot of water. This seems solvable, but currently not a lot of research in this area.

2) Sand - A TON of sand is required to keep these fracks open - we are talking truck load upon truck load of sand (sometimes over 100 truck loads). How does this happen in an offshore environment? The logistics would be quite tricky (and expensive).

3) Equipment - Typically, onshore drilling rigs drill the well, and then move off the location and the fracking unit comes onto the location. The fracking unit can be as big or bigger than the drilling unit spread. To translate this to an offshore environment would be logistically impossible - we would basically need specialized "fracking drill ships" to equivocate this. To date, these don't exist (but could potentially exist in the future).

4) Institutional Know-How - for how big these companies are, it's quite surprising that the big players haven't had much success fracking - ExxonMobil, Chevron, ConocoPhillips, BP, Total, Shell - all of these guys do some fracking, but it's not really their core business (offshore is). The fracking revolution was built on the backs of the smaller industry players (and these guys don't do offshore well). In tech parlance, this would be loosely equivalent to why Microsoft/Yahoo/Oracle have never really done startups well (just buy the ones that do well).

It's important to note that fracking we see in the news are a totally different target than conventional oil wells. So the permian basin, which is "so hot" right now, had conventional targets that were tapped out in the 1980's/1990's. The shale wells being drilled are entirely new wells at different targets, so you wouldn't use the fracking techniques that we hear about to extend the life of an existing well - you would drill a totally new well.

To give you an idea of the costs involved, an offshore deepwater drill ship in the Gulf of Mexico has a rig rate (all in) of about $500k/day. An onshore rig in the permian basin drilling shale wells is probably around $50k-$75k. It's a 10x difference (why is why countries like Brazil, Venezuela, etc. have struggled during this latest "boom").

Wow thank you for the long form answer, very helpful to read insights like this from someone in the industry!
Re:The United States Is Now the Largest Global Crude Oil Pro... by gonzo on Thursday September 13, 2018 @04:51AM (#17977062)
typically yes. Once the production rate start to fall, "fracking" can be used to raise it again.
Re:The United States Is Now the Largest Global Crude Oil Pro... by kd5bjo on Wednesday September 12, 2018 @05:50PM (#17973769)
Sure. It all depends on the geology of the particular oilfield the well is tapping, and how much money the well owner is willing to invest in increasing production. Similarly, there are vertical wells that have been fractured.

I don’t have the knowledge to get any more detailed, unfortunately — This is all secondhand from some oil industry software engineers.

Can those same techniques increase OPEC production?
Re:The United States Is Now the Largest Global Crude Oil Pro... by ejanus on Wednesday September 12, 2018 @11:01PM (#17975618)
Yes. But it increases cost variables. Virtually all the Wells in the gulf of guinea are horizontal.
