That is a really tight scope to turn into a business--Wellsite equipment just lasts too long to make a living off of it. My practice goes backwards and forwards a bit from the wellsite. I consult extensively on well deliquification and gathering systems in addition to wellsites, wellsite compression, and wellsite fluid measurement. Take a look at my web site (url is in my signature) to see the scope of my business, it is just a touch broader than you are talking about. There is a real shortage of people who can talk reasonably from the sandface/coalface to the plant inlet. Especially in low pressure operations.
I did a series of talks at a major Engineering firm last month. They had just gotten the contract to write a FEED for a new upstream development. I did an hour on Reservoirs for Facilities Engineers, an hour on water phase behavior, an hour on Wellbore Dynamics, an hour on wellsite compression, and an hour on fluid measurement. This was an experienced team that felt (at the beginning of the week) that they were perfectly competent to take on this project. At the end of the week the felt less confident, but better informed.
You get involved in deliquification by getting involved. I started in that area by asking a Production Engineer what the NPSH-r for an ESP that he wanted to install was. He didn't know, and didn't know what NPSH was. I explained NPSH, then explained cavitation. Then helped him pick a pump that made sense for his application and got a reputation as a flangehead that wasn't afraid of downhole stuff. Between helping the Production Engineers avoid some amount of stupid choices, writing a chapter of a book on Gas Well Deliquification, and writing Journal articles on Deliquification I think I've added value to the industry and it is a big part of my practice.
I learned about gas measurement by getting involved with the measurement community. It was not part of my job, but no one pushed me away when (after reading AGA-3 cover to cover a couple of times) I started asking questions. Eventually I was the Measurement Engineer for a major company (in addition to my other duties).
I got involved in Environmental stuff by offering to help those guys.
In short, your job is your job and: (1) you have to do it well; and (2) if you never step out of it no one will think less of you. On the other hand if you carefully step out of it (while still doing exceptional work on your job) into places you can make a difference, before long your scope will naturally increase.
I submitted abstracts for papers in Gas Measurement, Environmental Crap, Deliquification, and Separation. Most were accepted and I wrote the papers. I was an officer in the local SPE Chapter. I tried to be active in the local NACE and API chapters. I got to know a lot of folks (many of whom hired me for work after I started the business).
I called my 23 years with a major E&P company an apprenticeship for my real career as the owner of MuleShoe Engineering, but in fact I'm still learning. At 4 years I was in no way ready to add value in my own company.
