CSM Well #1 is reviewed. The tubing collapsed during a pressure test and was caused by pressure differential and compromised tubing. Before the pressure test the well was a very high producing well. The numbers for monthly values for average production can be found in Table. 1. The last month before the pressure test the total production form this wet gas well was a little over 45,000 MSCF/D. If the well cannot be saved then the well will have to be plugged and abandoned, making the production zero. The ways to mitigate the problems in the well will be determined by a lead impression block and downhole cameras. These will give us an idea of what is happening downhole.
The flowrates for oil are in the magnitude of the thousands and the gas flowrate is in the magnitude of one-hundred thousand. The well is a wet gas well because the GOR is consistently above 50,000 scf/bbl. The GORs can be found in Table 2. It is concerning that the workers left the well flowing while preforming the pressure test because it makes an unbalance in the tubing and the annulus. The liquid is in the tubing and the annulus is being pressurized. The liquid does not provide enough pressure to offset the pressure being applied in the annulus, creating a large pressure differential. |
