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 top hole drilling can put you ahead of project plan

If you were guaranteed to save 30 hours rig time by investing NOK 250.000 extra - would you do it? Well, someone did and they saved close to NOK 3 million. And got ahead of plan already after drilling the top hole.

Is equipment inspection & maintenance on the drilling rig profitable?

Most clients send their equipment on shore to get it inspected and maintained. Is this because of old habits, the nature of the business, or are there situations where it is beneficial to send certified inspectors to the rig?

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.

WBCU: Optimizing displacement while protecting completion equipment

OWS has developed a range of tools that allow multiple opening & closing of ports to allow on demand communication to the annulus and to allow rotation of the upper string when carrying out wellbore fluid displacements.

The Weight Set Circulating Tool and the Weight Set Swivel Tool have been successfully applied on two different projects, and in this article, I will share some of the experiences we had using the tools.

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.

Can Robotics on Rig Floor Make a Difference in Drilling Performance?

In a previous blog we have described the significant potential efficiency gain that lies in a fully automated drilling process, by use of intelligent robots at the drill floor. Before we go into details about how such a system could look, and how we can get there, let’s take a look at where we are on automation on our modern 6th generation rigs today.

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.
