Solutions for 2-Stage Cementing (English)
TAM International introduced the cementing Port Collar in 1984 to complement the Casing Annulus Packer (CAP) for 2-stage cementing operations. Evolution in the product line has progressed to allow two stage cementing of casing sizes up to 30-inches, in horizontal well applications, and with a metal-to-metal seal version for production casing.

لو وزن عمود ال CMT أعلى بكتير من ال fracture pressure of Formation وهيكسرها بنضطر نعملها على مرحلتين عشان نقلل ال CMT Hydrostatic Head بدل ما يبقى مرة واحدة ويكسر بنعمل مرة ونسيبه ي thicken وبعدين مرة تانية بعده

I don't understand the need for a multistage cement job.

Say your first cement rises in the annulus to a lost circulation zone so above this zone of loss, you'd have no cement. With this tool run ahead of time and above this zone of loss, you can open the port collar and pump cement into the annulus. Now you've succeeded in placing cement above a zone of loss. This is just one example of a need for a two stage cement job.

John Griffin Thanks for that explanation. That makes sense.

Kelli Hollinger In addition , if the hydrostatic column is too long and a bottom formation can not handle that pressure, you didide the CMT into stages. You could use multistage cementing to contraol any mud contamination

Hydrostatic and ECD effects makes it impossible to place cement ar desired length in annulus without losses. Another advantage is that in certain cases you do not have to wait for fist stage cement to set before pumping the second
Isn't it a joy to see that they all copy Baski, yet, his house is left to him, desolate.... interesting.
