Onshore monitoring - keeping high-quality TRS while reducing operators offshore

What question would you rather ask: –Where can I find the comments on connection #254, or –Why is there a higher torque on the connection you just made?

Consider the Crushing Factor when Setting Casing Slips

The crushing factor is the weight of the casing string in relation to the yield strength of the pipe. It suggests that you need more area of impact from the dies when the string gets heavier. This should be calculated by the drilling planner and it determines the type of pipe to be used.

Unbreakable connection? Here's your quickest fix

What do you do when you run into a casing connection that is impossible to break out? Do you send a man into the red zone with a reciprocator saw while the string is in the elevator? Or are you willing to spend some time rigging up a belt tong to assist where your roughneck or casing tongs were not able to deliver the required torque?

Hopefully not. We have safer and more efficient ways of handling P&A jobs with obstinate connections.

Confessions of a veteran: Why I would have used the CRT

I care about the string. At least, I did when was in charge of it. The solid grip of the elevator around the box felt comforting. No one could ever convince me that hundreds of tons of casing jangling from the top drive, with an inside grip, were a safe option.

I was saved by the bell. The new technology (well, new at that point) came along when I had moved up the ranks to my ultimate level of incompetence. There, I could cash in on the benefits from the new gear without having to lay my hands on it.

Would I think differently faced with the same challenge today? Sure! I would adopt the new technology with grace and bring my team to a level of efficiency, safety and economic supremacy previously unheard. At least that's what I like to think...

Protecting your tubular equipment is still important

The experienced oil worker will find this rather obvious, but it is never an option to cut corners when it's talk about protecting the casing tubular. Still, we see that routines are not followed or someone takes too many personal liberties. A quick brush-up of dos and don'ts, including a time-saving tip, will not harm anyone.

How CRTi and Ream Shoe can Reduce Casing Running Time and Costs

The risk of stopping casing jobs before reaching TD is greater for deep and/or deviated sections. The ability to ream casing down by using the CRTi (or CRTe)and a ream shoe overcomes challenging wellbore obstructions such as tight spots, ledges, high dog legs, cutting ‘beds’ or difficult deviated zones.

There are situations where Level 1 casing reaming could save up to 50 percent of the time or more.

Identifying Casing / Tubing is imperative to safe casing running

This is probably the most important part of a casing crew’s job; identifying the pipe and ensuring all equipment and tools are within the specs to handle and make up the connections.

Why is this so important? The crew needs to understand what type of connections they are making up. Are they all the same, or are there different types in one string? This is crucial as torque figures might differ, connection OD and ID might change, or perhaps the connection is completely different and not compatible.

There are many ways to identify pipe and I shall try to outline how this process is done and what to look out for.

How to reduce offshore risk during tubular running services

Running casing, by its very nature, can be a dangerous occupation with many pitfalls to be aware of. Contrary to popular belief, most accidents are preventable, which is why we must be aware of the hazards and take every precaution necessary by implementing the stringent safety measures while avoiding injury to personnel on the rig site.

Years of experience says nothing about your offshore competence

You may have heard the saying “You can have 20 years of experience, or 1 year of experience repeated 20 times”. In other words, if someone does the same thing in an inefficient way over and over they’re probably not as competent as that smart person that’s worked more efficiently in their first year.

Individuals that are faced with varying types of frameworks, systems, processes and challenges and have learned to problem solve in a dynamic and productive manner due to exposure, will have a wider overall grasp and a high standard of offshore competence.

Increase casing filling speed with autofill equipment

When running casing, one of the things you always have to keep in mind is keeping the casing string filled with mud.The reason for this is, of course, that you want avoid collapse of the casing.

But filling the casing takes time. Time better spent fulfilling your primary objectives of running the casing to TD, cementing and pressure testing it. The process of filling the casing usually takes between 1 and 1.5 minutes, depending on pipe dimension, pump rates etc. 1.5 minutes is at least a quarter of the time you spend on each connection, so any time saved on this simple task might have a huge impact on the overall operation time.
