Cable Tool Drilling- Starting A Hole

Just getting a hole started on this one, no stem guide. We just dig down a little over 2 feet with post hole diggers and the rig takes it from there. 20 ft of gray clay then we hit a pocket of sand and gravel. Also just put up a new forum for drillers at http://excoboard.com/drillersonline

can't drill with the jars on bottom - no weight for the bit - put the jars on top with a sub above to make hole.

@JAXTRUX Jars are on top, stem is down in the hole. I have the big string on, 2-3/4 x 3-3/4 tool joint.

Any advise on how to use the jars to help unstick my bit stuck at 198 feet in bedrock. Not having a good time so far. I've got a friction socket on it and set of jars. Do I need to reposition the spudding beam to a different point to make it hit harder on the upstroke? It a Bucyrus Erie 22w. Any experience with this kind of fun?

Thanks

Dan

@MrDanielHalen First, explain what happened and what all is stuck in the hole, is it the hole drill string bit, stem, rope socket, is there jars on the drill string? A friction may not hold good enough to jar a string loose, you might need a combination socket. I need to know whether you got stuck and cut the cable off, or if the cable broke off.

Get rid of the jar's they slow you down!!

hate to run without them, I drove the casing down through several clay and gravel formations one of which had some large rocks in it and one of them got up in between the channel of the bit and wedged against the casing and it stuck tight. I had a heck of a time jarring it loose, it would have been a bigger problem if I had not had the jars on. That rock came up with the tools still in the channel of the bit...

Great to see a working cable tool rig, I drilled water wells with BC 20w 22w and 29w

The last well I drilled was my own in '93, never used jars to drill except for core sampling overburden with a split spoon.

primitive.

5 stars thanks for the good advise and ideas.

Hey, grease the rope socket. It's not turning.

Depends on the size of the rig. Mine will probably go about 500 - 600ft. A Bucyrus Erie 22W rig can go about 1500 if I remember right, but the biggest cable tool I seen was a Walkaneer that could go about 7,000 feet. Most of the wells I drill in my area are usually between 100 to 200 ft but the rotary guys are running them 400 feet which is not really needed except for a few places around me where you really do have to go that deep and there's not much water in those cases.

Great video and thanks guys for expaining the jars. I remember my Dad mentioning "jars" in the drilling process but never did ask him what they really were before he passed away. Makes perfect sense now. I shot video months back of a spudder in action near me but don't think he was using the jars. I'll have to look at the video again to see.
