On April 26, 2000, Vibration Technology’s proprietary equipment and methods made it possible to
simultaneously recover a gravel pack screen and packer from a high capacity gas well located in South
East Texas. The Halliburton gravel pack completion assembly consisted of a packer, sliding sleeve, shear
release, blank and wire wrapped screen as illustrated in Figure 1.
In South East Texas, as well as throughout the surrounding Louisiana-Texas Gulf Coast and Offshore Gulf
of Mexico area, packer and screen recovery is somewhat of a routine maintenance procedure, normally done
over the course of several days using either jarring or washover techniques. Conventional fishing can be
tedious, time consuming, as well as costly and, as experienced oil industry personnel know full well, with
each step of a procedure there is an inherent risk of something else going wrong, sometimes with
catastrophic consequences.
This 5,500 Ft. well had experienced a dramatic increase in sand production to the extent that immediate
remedial procedures were required. The job was accomplished by leveraging the unique capacity of Vibration
Technology’s mechanical oscillator to "fluidize" sand, turning it into a quasi liquid state
that allows tubular goods to move freely through the gravel pack sand. Conventional fishing procedures were
not required.
The economics of this job proved favorable for the customer because of the elimination of three days
(more or less) of various services and costs that are conventionally required. But the real story is that the
well was back on production several days sooner than expected and without any "surprises" or
contingencies that often have to be overcome. Been there, done that?
"To our knowledge, simultaneous recovery has never been attempted much less accomplished" notes
Paul Moore, Vibration Technology Service Manager, in Shreveport, LA. "We used our 85,000 pound load
capacity oscillator and the job only took about 30 minutes to have everything free and started out of the
hole."
