"What we may have reached is peak oil at the limits of current technology. Future technology will surely have a peak oil, after several more limits of current technology. But what will happen is as the price of oil goes up (it might go down too) new developments in both extraction technology...

Well, I'm not sure if they are called mechanical engineers, but I expect the casing & tubing running crews to do the following when they arrive on my rig: 1. Check their gear (Has it all arrived? Is it everythiong they need? Is it all working? Is it all certified?) and tell me ASAP if there is...

Ask BOT!

"You can find a quote in B31.3 that is similar to the ones that BigInch provided above. B31.3 explicitly does not apply to well sites. ASME does not cover well sites at all (except pressure vessels that come under BPVC). API doesn't have piping codes. If your company does not have internal...

My Underrtanding of the ISO standards system is that teh ISO adopt a particualr standard as an ISO. SO for example many API standards are also ISO standards; the BSI quality standards became the ISO quality standards and so on. I don't know if an ISO certifcate exists.... Get hold of a copy...

While you are at it you might want to explore other threads: Hydril and Grant Prideco have various licenced thread forms that are being used on more and more drill strings, especially in the larger sizes (6-5/8" pipe and above) or in the smaller sizes (4" and below, where API NC connections...

TESCO (the oil services company, not the UK supermarket) are the guys to speak to. They have two systems: 1. the casing with used with a drillable casing drill bit (sort of like a reamer shoe on steroids). Good for vertical holes. The drillable casing drill bit is lot more expensive than...

It's a pretty standard type plot, mainly used to show if injectivity is changing with time (it almost always does, either increaseing due to thermal fracing or decreasing due to crud in the injection water gumming up the permeability).

There's the wireline cased hole pressure sampler from Schoumberger, where a remote wireline tool drills a very samll hole through the casing with a seal around it, extracts a sample of the reservoir fluid into the tool (often through a few analysers, so you can pump from the reservoir until you...

PLugs are used to seal up the tubing or casing bore, either permanently or temporarily. They are used to isolate zones above them for testing, or below them for squeeze cementing, fracing, or due to water production. Or to provide a solid base to the well to set a cement plug or a whipstock on...

1. A nipple allows you to land something in the tubing (the other alternative is to use a tool with slips that grip the tubing, but such things are harder to set and even harder to retrieve, so nipples are preferred). At it most basic, a nipple is just a section of reduced ID with a shoulder...

Depends on the company. Some companies keep the L/MWD and the DD guys separate, so in MWD the career path is: learn and run all the tools, on harder and harder wells and then (if you want, a lot of guys don't) come into the office as the Client rep/ Service Manager/ Base Manager etc. Other...

Surface wellheads are preferred- they're cheaper and much easier to get to. But to have a surface wellhead offshore, you need a platform. And platforms are expensive and reach a limit of about 1000ft of water (Shell's Congac platform was the deepest at about 1000ft). The guyed tower concept...

blacksmith you're correct. Shale oil is indeed immature kerogen containing rock (usually shale) that can be processed, either on the surface or downhole, to make oil. But there are some oil shale formations where parts of the formation did make it into the oil kitchen and did form oil, and the...

the site works for me.....

North Sea oil wells may be on the production unit above sea level, or they may be on the seabed and conencted to a production unit via a short (a few km) pipeline. On the production unit (which may be a platform fixed to the seabed or a converted oil tanker or a converted semi submersible rig)...

I'll back up the warnings given above of various hammer unions appearing to mate up but not actually being pressure tight. In the North Sea, common practice is to ONLY allow 1502 unions on a rig or platform, to remove any possiblilty of mis-matching different unions. But there are still...

I'd tend to agree with you... where there any pump sizing calculations done? If all the previous wells are vertical and it's the same size pump, then considering the inflow performance from a horizontal well (there are various different ones that assume the drainage area is rectagular or oblong...

Up to now I've always worked at larger companies that almost all used the Landmark suite of design software (Compass, WellPlan, StressCheck, WellCat) or at SLB where I used their design software (TDAS, Drilling Office etc). Now I'm at a smaller company who are frightened of Landmark's prices...

I'd guess it's joints... but do they mean range 1 (18-22ft), range 2 (27- 30ft) or range 3 (38- 45ft) drill pipe joints as per API 5D or range 1 (16- 25ft), range 2 (25- 34ft) or range 3 (34- 48ft) casing as per API 5CT or range 1 (20- 24ft) or range 2 (28- 32) tubing as per API 5CT or...
