The gel strength is the shear stress of drilling mud that is measured at a low shear rate after the drilling mud has been static for a certain period of time. The gel strength is one of the most important drilling fluid properties because it demonstrates the ability of the drilling mud to suspend drill solid and weighting material when circulation is ceased.
How can gel strength is measured?
Gel strength measurement is made on viscometer using the 3-rpm reading, which will be recorded after stirring the drilling fluid at 600 rpm to break gel. The first reading is noted after the mud is in a static condition for 10 seconds. The second reading and the third reading will be 10 minutes and 30 minutes, respectively. Continue reading →
One of my friends shares this slide, An Introduction to Oil & Gas Drilling and Well Operations. This slide is the educational material from the IOM3 Oil and Gas Division, UK (http://www.iom3.org/). This is show all the basic of drilling and well operation in very simple language term. Additionally, there are several images which help explain content in this document clearly. This is a very good document when you try to explain overall drilling and well operation to new team members who don’t have much oilfield experience. The subjects covered in this presentation are as follow;
•Why we drill wells
•The well life cycle
−Well design and construction
−Pipe handling and the drill string
−Drilling and drill bits
−Cementing (including plugging and abandonment)
•Well testing and evaluation
This is excellent oilfield footage about the overall process of offshore deepwater drilling and completion. It has about 5 minutes with good animation that will give you clearer picture of how the deepwater operation works from the beginning.
We also add VDO transcription for anybody who cannot catch all the content of the VDO. Continue reading →
