What Is a Field Ticket in Oil and Gas? Fields, Examples and How Digital Tickets Work

A field ticket is the signed job-site record of billable work in oilfield services. It lists the job, the well or lease, the date, the crew and hours, the equipment and rates, and the materials used. The operator's on-site representative signs it to confirm the work, and that signed ticket becomes the basis for the invoice. You'll also hear it called a service ticket, job ticket or LEM sheet (labor, equipment, materials).

Picture the last week of the month at a mid-size well services company. A crew lead drops a rubber-banded stack of carbon copies on the billing desk, and the billing clerk finds that one ticket has no AFE number, two carry a signature nobody can read, and another says "Well 2" on a pad with four wells. None of that work was done badly, but none of it can be billed until someone tracks down the company man, and by the time he calls back, those invoices have missed the month-end cutoff. That's, say, 30 more days of cash sitting on a clipboard. The next month, the company prints AFE, PO and full well name fields into every ticket book, and crew leads check them before anyone signs.

Sound familiar? Most crews treat the field ticket as paperwork that happens after the job. In practice, it's the invoice in draft form, and every gap on it comes back later as a delay, a short pay or a dispute.

Overview:

• A field ticket is the signed record of the labor, equipment and materials used on a job, and it's the basis for the invoice.

• The crew fills it in, the operator's company man signs it, and the billing team turns it into an invoice.

• Operators code every ticket to an AFE and a well, then bill their partners, which is why a missing AFE or a vague well name gets tickets rejected.

• Most payment delays trace back to nine fixable errors, and you can catch nearly all of them before anyone signs.

• Digital tickets close the gap between signature and invoice, and Equipt ties every signed ticket to its job, asset and invoice.

What does a field ticket contain?

Most field tickets have four parts: a header that identifies the job, the billable items (labor, equipment, materials and other charges), proof of the work, and signatures. Layouts vary by service line and contract, but you'll find the fields below on nearly every oilfield field ticket.

The API well number deserves a second look. It's the permanent identifier a state regulator assigns to a wellbore, and the base number has 10 digits: two for the state, three for the county and five for the well, as the Texas Railroad Commission's glossary sets out. Texas wells start with 42.

Many operators carry a longer 12 or 14 digit version that adds sidetracks and completions, following the PPDM US Well Number Standard. Why write all of it on a ticket? On a pad with six wells, "Pad 3" tells accounts payable nothing, while the full number leaves no doubt about which well the work was for.

How do field tickets differ by service type?

The core fields don't change much from one service line to the next. What changes is the detail an operator expects to see before approving the charge. Here's what a typical ticket bills, and what the customer usually checks, for six common services.

Use this as a starting point, not a rulebook. Each customer's MSA can add its own requirements, and the strictest customer you work for usually ends up setting the standard for your whole ticket book.

Who creates and signs a field ticket?

Three groups touch every ticket. The service crew creates it, the operator's on-site representative signs it, and the office turns it into an invoice. Each one checks something different, which is why a ticket that satisfies the crew can still bounce in accounts payable.

• The service crew creates it. The crew lead or field supervisor fills it in during the job and closes it out before leaving location.

• The customer's representative signs it. On most upstream jobs that's the operator's wellsite supervisor, usually called the company man, or a consultant acting for the operator. The signature says the work was done as described.

• The office turns it into money. Billing staff check the ticket against contract rates and build the invoice. On the operator's side, someone codes it to the right AFE or cost center and approves payment.

The handoff from location to billing desk is where most of the delay lives. Our post on turning field tickets into invoices shows how much of that step can now be automated.

Why the signature matters for billing and disputes

When an operator disputes a charge, both sides pull up the signed ticket: who was there, for how long, with what equipment, and who agreed to it. It's the service company's best evidence.

An unsigned ticket, or one signed by someone without approval authority, gives the customer a reason to hold the invoice. So does a vague description. Your master service agreement (MSA) with each customer spells out what it needs before it pays, such as a PO number, named approvers or supporting documents, so read it before the crew heads out rather than after the invoice comes back.

On paper, the process is simple. On location, it bends.

What should a field supervisor check before the customer signs?

It takes about two minutes. Before handing the tablet or ticket book to the company man, the crew lead reads the ticket the way the operator's accounts payable clerk will read it next week. That clerk wasn't on location, has never met the crew and is matching your ticket against a stack of others.

Five things to check, ideally on the tailgate before you walk over to his trailer:

• The AFE, PO or cost code is filled in. If the crew doesn't have it, ask the company man now, while he's standing there.

• The well name matches the sign at the lease entrance. On a multi-well pad, write the full well name and number, not "Well 2."

• The hours reconcile. Arrival to departure, minus standby, should equal the billed hours for each person.

• Standby has times and a reason. "Waiting on operator lockout, 7:00 to 8:30 a.m." holds up. "Standby 1.5 hrs" doesn't.

• Every extra has proof. Extra materials, after-hours work and third-party items need a note, a photo or a name.

The catch is that this check feels like one more delay at the end of a 10-hour day, when everyone wants to get off the lease road before dark. We'd still make it a standing rule for every crew, because two minutes on location replaces a two-week email thread with someone who no longer remembers the job.

How do operators use a field ticket after it's signed?

The operator doesn't just pay the ticket. Its accounting team codes the cost to an AFE and a well, then bills a share of that cost to the partners who own working interests in the well. That's why operators are so strict about AFE numbers and well names: a miscoded ticket turns into a miscoded partner bill.

Most wells have more than one owner. The operator runs the well, and the non-operating partners pay their share of costs under a joint operating agreement. COPAS describes joint interest billing as the way an operator reports those shared charges to the working interest owners.

The rules usually come from the COPAS accounting procedure attached to that agreement. Under the 2022 COPAS accounting procedure, the operator bills each non-operator by the last day of the month for the previous month's costs, and non-operators can audit those bills for 24 months after the end of the calendar year in which they were billed.

Here's where this breaks for a service company. A ticket with a vague description or a missing AFE doesn't just slow your invoice down. If a partner questions the charge in an audit two years later, your ticket is the operator's support for it, and when that support is thin, holding or short-paying your invoice is the operator's safest move.

From the operator's side, a field ticket isn't just a bill to approve. It's the support for every partner invoice that follows. What accounting teams want to see without picking up the phone is short: the AFE, the full well name, clear times and a signature from someone with authority to approve that spend.

Should you use paper or digital field tickets?

Paper tickets still work for a small company running a handful of jobs a week. They're cheap, familiar and never need a signal. Digital tickets win once many crews produce many tickets a day, because the real cost of paper isn't the ticket book. It's the time between the signature and the invoice.

One lost ticket is annoying. Fifty unbilled tickets at month end is a cash-flow problem.

The trade-off is real, though. Digital tickets cost a subscription and some crew training, and an app that needs a signal is worse than paper on a remote lease, so treat offline capture as non-negotiable. Worried about how long rollout takes? Here's how one Equipt customer described going live:

“We're impressed that Equipt's Rental Asset Management portal could go live in such a short amount of time. It's extremely intuitive and our employees can already envision higher efficiency and less headaches in their day-to-day operational workflows.”
— Bryan Willborn, President & CEO, Paloma

What does a completed field ticket look like?

Now let's look at an example: a completed oil and gas field ticket for a simple flowline valve replacement and pressure test. All company names, people, numbers and rates below are fictional and for illustration only.

Header

Line items

Description of work: Safety meeting and JSA (job safety analysis), 6:30 to 7:00 a.m. Waited on operator lockout, 7:00 to 8:30 a.m. Replaced two leaking 2-inch ball valves and one flange gasket. Pressure tested the line to the operator's specified pressure; it held with no leaks. Rigged down and cleaned up location, 4:40 to 5:00 p.m.

Attachments: Before and after photos, pressure test chart, signed JSA.

Signatures: R. Diaz, field supervisor, ABC Well Services, 4:48 p.m. K. Lane, wellsite supervisor, XYZ Operating, 4:52 p.m.

Why does this ticket get paid without a phone call? The AFE, PO and full well name are on it, and the standby has times and a reason. The hours add up too: 10.5 hours on site minus 1.5 hours of standby leaves 9.0 billed hours per person. A chart backs the test, and a named customer representative signed before the crew left location.

Pressure work like this is where ticket detail matters most. See how a pressure control equipment service provider captures technician hours, asset costs and certification status against every job on Equipt.

Which field ticket errors delay payment?

Most rejected or short-paid invoices trace back to a short list of ticket errors. How many of last month's tickets came back with one of these?

• Missing or wrong AFE, PO or cost code. AP can't match the invoice to approved spend, so it sits in a queue.

• Wrong well. On a multi-well pad, "Well 2" isn't enough. The cost lands on the wrong well or bounces back.

• Rates that don't match the contract. A crew working from last year's rate sheet creates a dispute on every line.

• Hours that don't add up. Billed hours exceed time on location, or two crews claim the same unit for the same hours.

• Missing or weak signature. No signature, an unreadable one, or a signer who can't approve that charge.

• Vague descriptions. "Worked on well" invites questions. Say what was done, to what, and why any delay happened.

• Unsupported extras. Standby, extra materials or after-hours work with no note, photo or approval.

• Late tickets. Three weeks after the job, nobody remembers the details, and the customer's field contact may have moved on.

• Duplicates. The same work billed twice makes the customer question everything else you send.

Most of these come down to missing data behind the charge. One Equipt customer, a wastewater solutions provider treating produced water for oil and gas operators, had billing disputes because its invoices lacked operational data to back them up. After tying usage, uptime, volumes and service history to every invoice, it reports fewer billing disputes. Its president and CEO put it simply:

“Real-time IoT data has optimized tracking, monitoring, billing, and decisions.”
— President & CEO, wastewater solutions provider (Equipt customer)

Software can catch several of these errors before they reach billing. An AI assistant for field operations can flag hours over a contract cap, or a rate that doesn't match the price book, while the ticket is still on the reviewer's screen.

How does digital field ticketing work, step by step?

Digital field ticketing swaps the carbon-copy book for an app on a phone or tablet. The bigger change is that the ticket is connected to the job from the start, so most of the header is filled in before the crew reaches location.

• The office sets up the job. Customer, well, AFE or PO, service type and price list are entered once, and the ticket inherits them.

• The crew opens the ticket on location. A good app works without signal and syncs later. Equipt's field service management software lets crews update jobs and tickets offline and syncs them when the device reconnects.

• The crew records the work as it happens. Time, equipment and materials are picked from lists, and rates come from the price list instead of memory.

• The crew attaches the proof. Photos, readings, test charts and safety forms go on the ticket itself.

• The customer signs on the device. The signature is stored with name, date and time. The ticket then locks, and any later edit leaves a record.

• The office reviews exceptions. Instead of rekeying every ticket, billing staff check the ones that break a rule, such as hours over a contract cap.

• The approved ticket becomes the invoice. Line items carry into the invoice and on to your accounting or ERP system. Some operators exchange tickets electronically using PIDX standards, which include FieldTicket and FieldTicketResponse schemas.

• The ticket stays linked to the job. Months later, anyone can pull up the ticket, signature and photos from the job or well record.

Most of the value sits in what happens after the crew taps submit, which our post on field-to-office visibility with digital field ticketing covers in depth.

Here's what that looks like at one Equipt customer, an integrated oilfield services provider and OEM. Its crews and dispatchers used to schedule jobs through phone calls, emails and spreadsheets, and approvals and quote-to-cash ran across separate systems, which made compliance checks and audit trails slow to pull together. Now requests, approvals, changes and invoicing run through one workflow with instant digital field ticketing and built-in compliance checks, and the company reports faster, more accurate invoicing with full audit trails.

“Equipt.ai brought our field service and manufacturing teams onto the same digital playbook... We've cut manual admin work, improved utilization, and can prove compliance on every job.”
— Vice President, Services and Operations, integrated oilfield services provider and OEM (Equipt customer)

In Equipt, digital field tickets sit in the same platform as dispatch, work orders, equipment and billing, so a signed ticket is already tied to its job, asset and invoice.

Are field tickets only used in oil and gas?

No. Oil and gas made the term common, but any business that bills for crew time, equipment and materials in the field uses a version of it. The name changes; the job of the document doesn't.

• Construction and EPC: time and materials (T&M) tickets record extra work outside the base contract, such as an added weld or a re-routed line, and the general contractor's superintendent signs them before they can be billed as a change. One EPC fabrication firm on Equipt digitized up to 8,000 orders a month and replaced paper across its pipe and module shops.

• Equipment rental: delivery and return tickets record what went out, its condition and meter hours, and what came back. Modern equipment rental management software pairs e-signed yard tickets with runtime data so the invoice matches what the customer actually used.

• Utilities, wastewater and environmental services: service tickets record crew time, truck hours and the volumes hauled or treated, often against a customer PO.

The details shift. A rental return ticket cares about meter hours and damage photos, while a construction T&M ticket cares about the change reference. Return tickets are also where rental revenue quietly leaks, as our piece on why returned equipment sits idle explains.

Rental and service groups have one more wrinkle: tickets that move between companies. One oilfield services group running rentals across a parent and subsidiary uses Equipt's Open Invoice integration to send field tickets between its two companies and into operators' invoicing systems without re-entering them.

Where should you start if your tickets keep coming back?

If you're still on paper, you don't need software to fix the worst of it. Add AFE, PO and full well name fields to the header of your ticket book, make standby start and stop times mandatory, and have crew leads run the two-minute check before every signature. Those three changes cover most of the errors in the list above.

If you run more crews than your billing team can chase, the case for digital tickets is simple: every day between the signature and the invoice is a day your cash sits on location. Look for offline capture, rates pulled from each customer's price book and a ticket that stays linked to its job and invoice. Our guide on what to look for in oilfield job tracking software is a good next read.

Field ticket FAQ

What is the difference between a field ticket and an invoice?

A field ticket records the work done on location: crew, hours, equipment, materials and the customer's signature. An invoice is the bill the office sends afterward, priced from that ticket and the contract rates. One invoice can cover several tickets, and if the two disagree, the customer goes back to the signed ticket.

Is a field ticket the same as a run ticket?

No. A run ticket records oil leaving a lease tank for a purchaser's truck or pipeline: the tank, the opening and closing gauges, temperature, API gravity and BS&W (basic sediment and water), which together set the volume the purchaser pays for, as AccountingTools explains. A field ticket records the services performed on location. Some water haulers call their load tickets run tickets too, so check which one your customer means.

Is a field ticket the same as a LEM sheet?

Mostly, yes. LEM stands for labor, equipment and materials, the three main sections of most field tickets, and many companies use both names for the same document. Some keep "LEM" for a daily cost summary on longer projects, but the fields and the signature step are the same.

Is a field ticket the same as a work order?

No. A work order is created before the job and tells the crew what to do, where and when. The field ticket records what was actually done and what can be billed. In a connected system the ticket is attached to its digital work order, so you can compare planned and actual work.

What happens if a customer rejects a field ticket?

Find out which line they disagree with, fix it and resubmit while the job is still fresh. The usual causes are a missing PO or AFE, rates that don't match the contract and unexplained standby. Keep the original, the correction and the reason together so the history is clear if the invoice gets questioned later.
