Tripping out or cashing in?

06.12.2019

Different methods and technology for reducing the number of well trips have been around for some years; however, as a result of the latest market down-cycle period, these approaches have gained fresh interest, creating a new wave of development in technology-based solutions. In this article I will go into further detail about three of Odfjell Well Services' main technologies on how to reduce ...

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

11.05.2017

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?

Deepwater Completions using Sliding Spider

10.03.2017

With large OD Completion assemblies and big, thick control lines going through the rotary, advanced completions often mean heavy, repetitive work and time consuming removal and replacing of the bushings. A sliding Spider will get your deepwater Completion to the bottom quickly and safely.

Drilling fluid properties and design

12.01.2017

 It is widely known that the drilling fluid´s primary function is to keep well control and prevent an influx of formation fluid to the well causing a blowout. The mud also prevents loss to the formation by keeping the hydrostatical pressure. Not a big issue in the top sections of the well. As we approach the reservoir, however, the consequences of a loss to the formation is critical. The ...

Casing equipment load rating: Deeper wells challenges lifting capacity

29.09.2016

Oil wells nowadays get longer because the equipment is so much better. Old wells are lengthened and new wells penetrate reservoirs as deep as 11000 meters. What are the consequences for the choice of casing handling tools?

How to tell which connection is causing a casing leak

15.09.2016

Let's say you have 4000 meters of casing in place. You run the pressure tests, and your numbers are just not right. You go through the procedures again, but the deviation is still there. How can you tell wich of the several hundred connections causing the casing leak? Is it the one on 150 meters, or the one on 3750 meters? It is a guessing game, and your only option is to pull the whole casing. ...

Training new TRS technicians: The days of yelling and patronising are over

01.09.2016

Being a casing operator is so much more than being able to handle the tools. As a TRS Technician you need a wide understanding of the role, must be a bearer of safety culture, have basic communication skills and know how to behave on a rig to be regarded a qualified one.

Consider the Crushing Factor when Setting Casing Slips

19.08.2016

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

04.08.2016

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 ...

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

21.07.2016

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 ...
