    • Cost Detail for a Horizontal Well

      I'm looking for a breakdown of the cost components of a recent horizontal well. I know they generally cost $4-8 million and the hydraulic fracturing is usually more than the drilling cost, but I don't have a good split between rig rental, casing and cementing, mud supplies, directional drilling, fracturing, etc. Does anyone have a recent AFE that they could share? (maybe black out any identifying information if you need to keep it confidential).

    Great question, Paul. I'm going to stay tuned to this thread and see if a redacted AFE turns up - as you noted that would be your best source, have the most detail, and be the most recent indication.

    That said, costs components can vary quite a bit regionally (variables like local equipment availability and resource depth and complexity impact play-by-play costs). A Marcellus AFE might look a whole lot different than a Niobrara AFE.

    With that in mind, I wanted to provide you with some "average well" estimates that I compiled not too long ago based on datapoints disclosed by E&P, drilling and service company management teams. This may be a bit more general than what you were looking for, but it will give you a sense of how costs have changed as the industry has moved from vertical (conventional) wells to horizontal (unconventional) wells.

    Interestingly, just the frac cost of an unconventional well alone actually exceeds the entire budgets of many conventional wells drilled in NAM over the past 10-15 years. Its not that drilling costs have come down, but completion cost growth and intensity has been explosive.

    In the past, drilling budgets could account for as much as 60-70% of conventional well costs, with the drilling rig itself grabbing 15-25% of the total well cost. Today, the roles have been reversed with the advent of multi-stage fracing, steadily increasing drilling rig efficiencies, and horizontal drilling proliferation. Completion spending has steadily gained share.

    Modern drilling budgets (including set up costs, fluids, rental equipment, rig, bits, casing, P&A, and labor) comprise 35-40% of the total unconventional well cost. Drilling rigs make up about 8-12% of total well costs. Meanwhile, completion budgets now comprise 60-70% of the cost of unconventional wells. Frac spreads and the stimulation process/consumables can grab half the spending on any given unconventional well today.

    With average horizontal footage per well rising, and stages per well up big as well, the completion wallet that service and frac contractors are targeting should continue to grow (and likely has grown since we compiled these estimates).

    I look forward to seeing additional responses with more detail around the completion components.

      Great information, Joseph. It looks about right to me and I appreciate your response.

      I'm still hoping to get some more detail on individual cost items so that I can observe some of the current costs per unit. As you noted, total well costs can be quite different by area and even quite different within the same area -- particularly since available leased space can impact the length of laterals. Also, as you noted, the fracturing technology is evolving with new methods (such as open-hole sliding sleeve), greater intensity, more focus on natural fracturing and better monitoring tools.

      Excellent and informative reply, Joseph. Thanks!

      Bob, thank you very much! Can you tell me a little more about the well such as the area and total depth. I see that it has an intermediate casing string and I assume it is an oil target due to the rod pump.

    • Bob Malone 5 hours ago · [url=]Like[/url][url=]Unlike[/url]· 1

      Paul it is a well in New Mexico.
      The TD is 12,500'.
      Yes, it is an oil well.

        Mike, I would be interested in the AFE also if possible. Thanks Glyn

      You might want to look at a 2012 University of Pittsburg report at the address below to see some of the details generated from a Marcellus Well

      http://d-scholarship.pitt.edu/10484/1/PittMarcellusShaleEconomics2011.pdf

      or one done by Rigzone in the Eagle Ford based on a survey of operators in the region, drilling & completion cost per well ranging from $5.5 to $9.5 million:

      https://www.rigzone.com/news/article.asp?a_id=108179

      These were done a few years ago but I hope this helps.....looking forward to see information anyone might have from 2013-2014 timeframe.

        Linda, thank you for the links! They both have useful information. There sure is a big difference in stimulation costs on Eagle Ford vs. Marcellus wells according to those reports.
