Actually bdalh385, a jack pump is perfectly fine for this type of well.
Regarding proper equipment, given the type of pressure that the Collins revealed, 2000-2500psi....... :O))........., the equipment that an O&G Company wants to be concerned about and to make absolutely sure that it is proper, which Hemi address immediately with the Collins, is that the proper well head was installed in place to handle this type of pressure; otherwise a blow can occur and the well could be lost. Let alone the environment issues that go with a blow out.
I am surprised, given the background that you claim to have in the O&G industry, that you do not see the difference and importance of a proper well head being in place to offset and handle the pressure; the pump jack is down stream from the well head.
