- In this video we examine some of the differences between conventional wells such as a sandstone well and an unconventional wells such as a Marcellus or Utica Shale well. We examine reservoir differences, surface footprint, production volumes, and more.
Hi, Amazing work. It is actually very good to understand the rig parts on a live video. Animations and pics really don't help to understand the full mechanism behind the work that is being done.
Best info before interview 😂
Hope it helped!
@@OilfieldBasics unfortunately it did not. They were like: "we will definitely tell you about results of this interview" and i haven't heard anything from them since. Although they didn't asked me about conventional and unconventional wells difference.
What about the environmental impact differences between conventional and unconventional? From my understanding conventional wells are not going to poison the waterways around and damage the ecosystems...
Hi Breeanan! Thanks for your question! This is definitely one for a longer discussion, but I believe what you're likely referring to is the increased size of modern operations (thus a larger footprint and thus larger potential impacts). If you're actually looking at the well itself, I'd say older conventional wells would be more likely to have an environmental impact. Older wells (especially shallow ones) aren't as likely to have as many environmental protections in place with their design. For example, casing strings. Modern wells are designed for asset and environmental integrity. In terms of modern-day - if you were to drill a conventional well or an unconventional well, I don't really think there is an automatic difference in risk. It's very dependent on design and the scope of drilling and completion operations. For example, a modern-day conventional well might utilize more acid for its completions, whereas an unconventional utilizes more water volume to complete the well. I could keep going with examples. If you've got a specific instance you're thinking of, I can help to flesh it out with you. Otherwise, it's really hard to put a blanket statement out about which one is more environmentally sound. I think our biggest impact environmentally though (across the board) is just land disturbance. Thankfully, there are ways we can reclaim most of the land once the wells are drilled and brought to production. As for the waterways, I'm curious to know what you're referring to. Are you talking about when there's been a surface release from something going wrong during operations, or are you actually talking about the well seeping chemicals underground?
@@OilfieldBasics One thing is for sure: it's way more clean than mining for rare earth elements!

Noted. But I'm sure I'll forget tomorrow.
