Is it possible to drill a top hole to 42" in one run if the template is 38"? Here is the story of three parties putting their expertise together to save runs, time and money.
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?
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.
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 permeability is reduced, and the danger of emulsion is lurking in the dark.
Christmas is coming, and 2016 is will soon be history. It has been an excellent year on The Well Blog thanks to you faithful readers out there making more than 132.000 visits to read our articles. That is more than 30% increase from last year. We like to think that this proves the blog's relevance and that the articles resonate well with our audience.
Since January, we have published 32 articles and here are the top 10 most read, starting from # 10.

How can we prevent making the same mistakes? How can we ensure that we follow best practices throughout the organization? How can we keep track of people and gear? Also, how can we simplify the invoicing process? At Odfjell Well Services we are currently in the verification phase of a roll-out of global standards connecting all parts of the value stream - including HR, time capturing, logistics, planning, financing, mobilizing, demobilizing and maintenance processes- across all sites and business units. By doing so, we increase both safety and efficiency, positioning ourselves for growth. I will share with you the strategy and the thoughts behind this tough project.
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?
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. Or, is it?
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.
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.
