Abstract

Systems and methods for handling wellsite packets for a wellsite are provided. The wellsite packets include soluble packaging with wellsite materials therein. The wellsite has surface equipment and downhole equipment positioned about a wellbore. The handling system includes at least one feeder, at least one mixer, at least one metering device, and a pump. The feeder moves the wellsite packets directly or indirectly into the mixer. The mixer stimulates dissolution of the soluble packaging so as to mix the wellsite materials with a fluid to form a wellsite mixture. The metering device selectively controls the number of wellsite packets moving to the mixer. The pump is operatively coupled to the mixer to pump the wellsite mixture at the wellsite.

First claim

What is claimed is:

1. A system for handling wellsite packets for a wellsite, the wellsite packets comprising packaging with wellsite materials therein, the wellsite having surface equipment and downhole equipment positioned about a wellbore penetrating a subterranean formation, the handling system comprising:
at least one feeder comprising a reel rotationally mounted on a reel support, a chain of the wellsite packets releasably wound about the reel, the chain of wellsite packets unwindable from the reel and into at least one receptacle;
at least one mixer operatively coupled to the at least one receptacle, the at least one mixer to mix the wellsite packets with a fluid to form a wellsite mixture; and
a pump operatively coupled to the at least one mixer to pump the wellsite mixture to the wellsite.

2. The handling system of claim 1 , further comprising at least one metering device comprising a gate operatively connectable to the at least one feeder and having a passage therethrough, the gate movable between an open and closed position to selectively control a number of wellsite packets moving from the at least one feeder through the passage and into the at least one mixer.

3. The handling system of claim 1 , further comprising a motor to rotationally drive the reel.

4. The handling system of claim 1 , further comprising drums to receive packaging from the chain of wellsite packets, the packaging removable by the drums whereby the wellsite materials are releasable therefrom.

5. The handling system of claim 4 , wherein the gate comprises a knife to cut the chain.
