How is pressure doing for the second circulation of driller’s method
I just got questions from my friends asking about how casing pressure and drillpipe pressure react while performing the 2 nd circulation of driller’s method.
I have this post for somebody missing about the first circulation of driller’s method – How are pressure and pit volume doing during the first circulation of the driller’s method?
During 2nd circulation of driller’s method, we need to hold casing pressure constant until kill weight mud to the bit and then we will hold drill pipe pressure constant. The reason why we do like this is that we need to maintain the constant bottom hole pressure.
Drilling Mud Blog
I have my new web blog which I use for writing about drilling mud.
Please feel free to visit and subscribe your email as well.
I will keep updating my both oil field blogs as usual. I wish my blogs would help you learn about drilling.
What is space out in drilling (especially in well control)?
I got a question asking me about what the space out means.
Space out means that you stop your drill string at the proper location where all the BOP rams (annular and pipe rams) will not close against a tool joint. Please see the figure below for more understanding.
Driller’s Method Quiz No. 4
Let’s have one more test in order to remind you about the first circulation of driller’s method.
When you shut the well in, you record these following pressure readings.
Initial Circulating Pressure (ICP) = 1500 psi
Original Shut in Drill Pipe Pressure = 500 psi
After you circulate the 1 st step of driller’s method, you see drill pipe pressure and casing pressure reading like this image below.
What do you think about this well?
