1. An apparatus for releasing chemical agents in a well bore, comprising:
- a downhole chemical release package, wherein the downhole chemical release package is directly coupled to a tubular and comprises;
a packaging material, wherein the packaging material defines a top surface of the downhole chemical release package extending away from the tubular;
a chemical agent, wherein the chemical agent is contained within the packaging material;
an adhesive, wherein the adhesive is attached to the packaging material, wherein the adhesive defines a bottom surface of the downhole chemical release package opposite the top surface, and wherein the adhesive directly couples the downhole chemical release package to the tubular; and
a pressure activated release mechanism, wherein the pressure activated release mechanism comprises;
a flexible ring disposed between the packaging material and the adhesive such that, at atmospheric conditions, an air gap is formed between the packaging material and the adhesive; and
a plurality of puncture points disposed between the packaging material and the adhesive such that, at a selected pressure, the air gap compresses to allow the plurality of puncture points to pierce the packaging material.

6. A method of delivering a chemical agent comprising:
-
providing a downhole chemical release package, the downhole chemical release package comprising a packaging material defining a top surface of the downhole chemical release package, a chemical agent contained within the packaging material, an adhesive attached to the packaging material and defining a bottom surface of the downhole chemical release package opposite the top surface, and a pressure activated release mechanism, wherein the pressure activated release mechanism comprises; a flexible ring disposed between the packaging material and the adhesive such that, at atmospheric conditions, an air gap is formed between the packaging material and the adhesive; and a plurality of puncture points disposed between the packaging material and the adhesive; coupling the downhole chemical release package to a tubular such that the top surface of the downhole chemical release package extends from the tubular, by directly coupling the adhesive to the tubular; introducing the downhole chemical agent into a subterranean formation; and allowing the downhole chemical release package to release the chemical agent. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method comprising:
-
providing a tubular; attaching a downhole chemical release package directly to the tubular, the downhole chemical release package comprising a packaging material defining a top surface of the downhole chemical release package, a chemical agent contained within the packaging material, and an adhesive attached to the packaging material and defining a bottom surface of the downhole chemical release package opposite the top surface, wherein the adhesive directly attaches the downhole chemical release package to the tubular such that the top surface of the downhole chemical release package extends from the tubular, wherein the downhole chemical release package further comprises a pressure activated release mechanism, the pressure activated release mechanism comprising; a flexible ring disposed between the packaging material and the adhesive such that, at atmospheric conditions, an air gap is formed between the packaging material and the adhesive; and a plurality of puncture points disposed between the packaging material and the adhesive; introducing the tubular into a subterranean formation; and allowing the downhole chemical release package to release the chemical agent. - View Dependent Claims (13, 14)
