Wellbore Diagram Software - About Us

PetroCode, LLC was founded in 2010 for one reason to create a wellbore diagram software package that would be a better alternative to Microsoft Excel.

The initial development of Well Shadow lasted a year and half, but we did not stop there. PetroCode, LLC continues to develop new features and improve upon on existing features. Our development process is on-going and recorded to ensure users are receiving a current and efficient wellbore diagram software application. Visit our Version History page to learn more about recent updates.

Well Shadow users range from small companies to large corporations in various geographical locations, stretching from the west coast to the east coast and throughout Canada. Our goal is to accommodate for all of your wellbore data input requirements and provide you with wellbore diagrams that are easy to use, easy to access and effectively organized.


Jeff Frederick - President of PetroCode LLC and Founder of Well Shadow

In 2000, I graduated from the University of Tulsa with a petroleum engineering degree. After graduation I worked for several exploration and production companies within the oil and gas industry, ranging from small independent companies to large $40 billion independent corporations. Regardless of the size or worth, each of these companies shared the common use of Microsoft Excel to generate their wellbore diagrams. After ten years in the business I discovered the need for a more efficient and streamlined software application to generate wellbore diagrams, so I founded PetroCode, LLC and created our wellbore diagram software application called Well Shadow.

Don't Take Our Word for it,
Here's What People Have to Say About Us.

“Well Shadow provided a Huge Benefit...”

Well Shadow has provided a huge benefit to our small company. Prior to Well Shadow our wellbore schematics were either custom made by each engineer, printed and then filed, or hand drawn and filed. The problem was lack of consistency.
