Wellpro Overbalance Tubing Conveyed Perforation Solutions Creates Pathway from Reservoir into Wellbore Using 7” 12SPF HMX BH Charges

Background

A Major IOC required to carry out overbalance perforation to access the E1000 and C5200 sands on one of their land wells.

The deployment was planned as 2 runs due to the almost 2000ft intervals between both sands
Wellpro TCP Guns were loaded as per client perforation intervals and mobilized to the location along with firing heads and ancillary equipment

Operation

7” Guns loaded 12 SPF with HMX Big Hole charges at 30-degree phasing were prepared as per the client-provided intervals
The guns were made up of 2 hydraulic firing heads with time delay.
As per safety protocol, sufficient spacers were run on the top gun as well as to separate the upper and lower peroration intervals
The BHA was run in the well along with Retrievable bypass packers and all other ancillary tools
On correlating the guns to depth with the Radioactive marker sub, the packer was set and hydraulic pressure was applied to activate the firing heads

Achievements

The perforating guns detonated at the pre-determined activation pressure and both intervals were perforated simultaneously with sufficient surface indication
Upon pulling out of the hole, all shots were fired and in scallops.
A total Interval of 20 feet was perforated with the HMX Big hole charge creating a large entry hole diameter for gravel pack access
