By Amanda Leon, founder of OilMoney.io. Houston-raised, came up in the Houston marketing team of Vallourec, and has run Unrth, a brand and growth studio for oil and gas and industrial companies, since 2017, with her boots on client locations in Midland and Odessa. Last reviewed October 20, 2026.
You know the company man on location, and you know the rig crew. The name you may not know is the one on the well plan: the drilling engineer who decided what goes in the hole, wrote the budget around it, and may be the one grading your run when it's done. You're being graded whether or not anyone shows you the grade.
A drilling engineer designs the way an oil or gas well gets built. That's the U.S. Bureau of Labor Statistics definition, and EOG's Senior Drilling Engineer posting in Midland adds the parts a seller feels: writing AFEs, analyzing drilling performance and costs, and evaluating vendor performance.
What a Drilling Engineer Does
The BLS splits petroleum engineers by the stage of the well they handle. Drilling engineers design ways to construct oil or gas wells. Completions engineers decide how to finish the well so oil or gas flows up. Production engineers take over after drilling, track output, and look for ways to raise extraction.
The drilling engineer comes first in that line. If your product goes into building the hole, it goes through this engineer's design, and the people on location are working from a plan this engineer wrote.
The Midland Posting That Spells Out the Job
EOG Resources posted a Senior Drilling Engineer opening in Midland (Job ID 10871) on October 29, 2025, and it was still up on October 18, 2026. Line for line, it's a fair list of what a drilling rep gets measured against.
- Vertical and horizontal well planning and design. This is where your product gets written into the well or left out of it. Getting into the spec before the bid is its own skill, covered in how to win an oil and gas RFP without being the cheapest bid.
- Writing AFEs. The AFE is the authorization for expenditure on a well, and in this job the drilling engineer writes it. Your price lands inside a budget this engineer built, so make it easy to drop in: clear pricing and no surprises on the ticket.
- Analyzing drilling performance and costs. Your run gets measured on both. Know your own numbers on their wells before they bring them up.
- Evaluating vendor performance. It's written into the job. Every run you make on their wells goes into that grade.
- Applying new technologies. There's room for something new, if you make the case in this engineer's terms: performance and cost on a well like theirs.
- Daily engineering supervisory support for multiple drilling rig operations and well site supervisors. One engineer, more than one rig. Keep what you send short and easy to check. For the operator's representative out on location, see selling to the oilfield company man.
Bring the Engineer an Angle From Outside
My liberal arts education taught me to think outside the box. When a problem in drilling is still sitting there unsolved, thinking only like a drilling engineer probably won't crack it, because if it could, it would have been solved by now. Come at it the way a rocket scientist would, or a homemaker, or an interior designer, or anyone else, and bring the principle that works in their industry back into yours.
That's your way in on the new-technology line. The engineer already thinks like a drilling engineer all day. What you can bring is the angle from outside: the principle that worked somewhere else, and why it holds downhole. Then prove it the only way this engineer will take it, in performance and cost on a well like theirs.
Casing Costs and the Well Budget
Diamondback Energy is naming casing out loud. In its August 3, 2026 letter to stockholders, it said it hadn't seen significant service cost inflation outside fuel and fuel-adjacent costs, but expects inflation on fixed costs such as casing through the rest of 2026 and into 2027. On the trade side, a presidential proclamation dated June 3, 2025 raised the Section 232 tariff on imported steel articles and derivative steel articles from 25% to 50%, effective June 4, 2025.
The engineer writing the AFE needs a casing number to put in it. If you sell OCTG, explain plainly what's moving your price, including any imported steel and that tariff, and speak up early when the number changes. A quote that shifts after the AFE is written leaves the engineer holding a budget that's already wrong.
Mill-Direct Pipe and Rig Schedules
I came up in the Houston marketing team of Vallourec, the French maker of VAM premium connections, pulling apart international drilling marketing data, so weigh my read on pipe makers with that in mind.
Tenaris built a service around getting pipe ready for the rig. In December 2016 it opened a $36 million service center in Midland for OCTG storage, inspection, rig preparation, and delivery, and in 2016 its Rig Direct service accounted for about 90% of its Permian Basin OCTG sales, according to Drilling Contractor. In its Form 20-F for fiscal 2025, Tenaris said it expanded the scope and deployment of Rig Direct across North America, adding digital solutions and deeper supply chain integration.
For an engineer supporting more than one rig, pipe that arrives inspected and prepared for the rig is the offer you're up against if you sell pipe another way. Know what you add to the engineer's rig schedule, and say it in plain terms. More for pipe, valve, and pump reps is on the equipment and supply reps page and in how OCTG, PVF, and pump reps get known.
Rental Tools: Two Doors Into the Same Well
A rental tool rep has two doors, and Drilling Tools International's 10-K for fiscal 2025 shows how evenly they can split. About 48% of its 2025 revenue came from oilfield service companies such as Baker Hughes, Halliburton, and SLB, and about 48% from operators such as Chevron, EOG, and Occidental. Its fleet is concentrated in the Permian, its tools rent mainly on daily fees with charges for lost or damaged tools, and it says drilling contractors rarely rent tools on an operator's behalf.
So when the operator rents, the order comes from the operator's side, and the drilling engineer is one of the people to know there. Don't wait on the rig contractor to place it for them. When a service company rents, you're selling to that company's people. Know which door each job comes through, and be known at both. Settle how lost or damaged charges work before the tool goes downhole, so the ticket doesn't turn into the argument.

What the Engineer Finds When They Look You Up
If you've already run on this engineer's wells, your record is in the room before you are. If you haven't, there's less to go on, and your name carries more of the load.
A drilling engineer who looks you up should find proof you understand their well: the kinds of runs you've supported, the problems you've solved downhole, and how you handle a tool that comes back damaged. Plain words. No brochure. For the procurement side of the same operator, see getting known by supply chain.
The founder we work with, a fourth-generation oilfield man who founded a service company in the Permian, is at a podium in a suit when the job calls for it and in the field the rest of the time, and by October 2026 the most common job title among his followers was drilling engineer. Those are the readers you want finding you. Read the full story.
The Warm Walk-In™ is how we build what the engineer finds under your name: you give us one story dump a quarter, typed or spoken, we write posts in your voice, and you approve each one before it goes out.
What a Profile Cannot Do After a Bad Run
The engineer evaluates vendors on performance and cost on their own wells, and EOG's 2025 Midland posting writes that into the job. So a profile never outweighs a bad run. If the tool failed or the bit came out early, the engineer's numbers say so, and no post argues with them.
A profile helps with one thing: the engineer knowing who you are before the first run. The run decides the rest.
