0psi SPP/3bpm - through tubing motor clean out BHA.
Issue: When we test motor shallow nearly 100m we see some pressure but when we get down 1600m we see zero pressure.
Fluid: water 8.4ppg
Shallow test motor: 2bpm / 290psi
1600m test: 2bpm/0psi.
The well is on total losses and the fluid level is around 1000m.
2 7/8" motor: Max. 120gpm and 870psi diff across motor.
We are trying to clean inside 4 ½" tubing which is at 3500m. we are not on depth yet will see what happens when we get it to work.
Any ideas of why we see no pressure with a motor in the hole given that the motor is function tested and ok.
