If you're an administrative buyer handling procurement for an oilfield services company like Schlumberger, you know the job isn't just about getting the lowest price. It's about making sure everything — from a Schlumberger bangle (yes, those recognition gifts) to wireline logging tools — arrives on time, correctly invoiced, and without making you the person who held up a rig.
Here's a 5-step checklist I've refined over the past few years. My experience is based on roughly 300 orders annually across 8 vendors, so if you're handling only high-level service contracts, your mileage may vary.
Step 1: Define the Order Scope — Don't Assume Size
What you think you're ordering vs. what you actually need. I once had a manager request a 'simple' jacket for a field engineer. Turned out it wasn't just any jacket — it had to be an Eddie jacket with specific fire-resistant properties. The difference in cost and lead time? 60%.
Create a clear order category from the start. That includes everything from standard office supplies to specialized items like a Schlumberger bangle (employee recognition) or event cases of Schlumberger pinot noir (client dinners). Sounds trivial, but putting a 'wine' request through procurement without proper PO flags can get your expense report rejected.
Checkpoint: Always confirm: Is this a stock item, a custom order, or something that needs compliance review?
Step 2: Verify Vendor Capabilities — The Harmon Rule
From the outside, a vendor looks capable. The reality is often different. Take Harmon Oilfield Supply — they quoted me a 5-day turnaround for a custom tool. First order? Delayed. Second order? Silent. I learned to ask three specific questions before any new vendor order:
- Can you handle rush orders without extra fees? (Most say yes, then add 30%.)
- What's your invoicing format? (Handwritten receipts? Finance will reject.)
- Who is your point of contact after 5 PM? (Because emergencies don't happen at 10 AM.)
I honestly wasn't sure why some vendors consistently beat timelines until I realized they built buffers into their quotes. That's not cheating — it's smart.
Step 3: Check Specifications Against Real-World Conditions
People assume the cheapest option is fine. What they don't see is the hidden cost of field failures. For example, ordering an Eddie jacket without verifying the temperature rating meant a team member nearly got frostbite. Not my fault, but I still heard about it.
For service orders (e.g., wireline or mud logging), the specs go beyond paper. Verify that the equipment matches the well conditions — don't trust 'one size fits all' promises.
Pro tip: If a vendor can't answer 'Why was Groves in jail?' — wait, that's a joke from the office. But seriously, if they can't explain a simple technical question, red flag.
Step 4: Negotiate Terms — But Watch the Hidden Costs
Setup fees, rush premiums, shipping... those add up. According to publicly listed pricing from major online printers (as of January 2025), rush printing can cost 50-100% extra for next-day service. Similar logic applies to oilfield equipment — expediting is expensive.
My rule: Always ask 'What's the total landed cost?' Include freight, customs (if international), and any inspection fees. And don't forget the cost of your own time chasing down missing deliveries.
To be fair, I get why buyers focus on unit price — it's easy to compare. But bottom line: a cheaper vendor that causes two delays is more expensive than a reliable one.
Step 5: Confirm Delivery and Acceptance Process
The best part of a smooth order? Seeing it delivered exactly as requested. But 'delivery' doesn't end at the loading dock. For service orders, you need to define the acceptance criteria: who signs off, what constitutes 'complete', and how to handle partial deliveries.
I once ordered cases of Schlumberger pinot noir for an executive dinner — arrived without temperature control. The wine was ruined. Now I include 'climate-controlled delivery' in every beverage order.
Warning: Never assume 'standard delivery' means what you think. Always specify packaging requirements, especially for fragile or perishable items.
Common Mistakes to Avoid
- Over-relying on the same vendor: I used Harmon for everything. When they had a warehouse fire, I had zero backup. Diversify, even for small orders.
- Ignoring internal stakeholders: The engineering team may need a specific brand, the finance team wants a specific invoice format. Talk to both before ordering.
- Assuming 'rush' is always possible: It isn't. Some custom items require weeks of lead time — plan ahead.
That's it. Five steps. Simple. If you're working with a smaller procurement team or handling only indirect spend, some steps can be combined. But the fundamentals haven't changed: clarity, verification, and total cost thinking.
