I am researching onshore brown field low cost well design options. For example Radial Drilling with coiled tubing.
My question: –
“I would like some advice from the forum about what else is out there that I should be considering for brown field low cost well design options e.g. Radial Drilling?"
Feel free to ‘brain-storm’ a list, but it would be most helpful if you could be as specific as possible with the name of the technology and perhaps advise if you are familiar with any of it
Adam, thank you for your response. Can you please send me your work email.

How are you doing? I have a few ideas (indirect ways of reducing overall cost) which can be tried out in achieving low cost well design.
1. How to reduce rig move time between the drill pads - have meetings with rig manufacturers and float an ITT with concept "Rig On Wheel".
2. Casing while drilling - technology has gone too far on this with PDC drill shoes. They are available which can drill formations having compressive strength up to 25k.
3. Wellhead design - some older fields can have up to 15 designs of well head (various sizing of the tubing head spools). Reducing to minimum number of well head designs without impacting production profile surely will reduce overall inventory and future maintenance cost.
4. Rig contractor - crew pays a significant role and their competency. Faster drilling rate can be achieved by various tools but without drill crews efficiency in particular development brown field flat time can not be reduced. This can impact hard in overall performance.
5. One way to increase efficiency is to keep track on the various times like slip to slip time, tripping speeds, pipe make time etc. between the two shifts. This is slow process but based on learning from this effective measures can be taken to improve drilling practices which will ultimately tuned in the overall efficiency. We have used company called Pronova for this. (Note from moderator: rp-squared also have a lot of experience with this via our performance coaches)
6. Casings - Its a good idea to re-evaluate casing requirements. Since its brown field, re designing casing with current geological information to see if lower grade casing can be used.
I hope this will help in further brain storming.
thanks & regards
