Your inbox has five vendor decks in it. Each one claims to be the answer. None of them asks what layer of the stack you actually need filled first. That question is the whole decision, and the vendor who leads with it is the vendor worth talking to.

The oilfield automation landscape comes in every shape and size, from the majors like Rockwell, Emerson, and Siemens, to oilfield specialists like AutoSol and Kimray, down to the remote-monitoring and pumper-app vendors serving producers who never had SCADA or are moving away from it. Which one you buy from depends almost entirely on which layer of the stack you are trying to fill.

Most producers don’t need a comprehensive vendor list. They need to know which companies play at the layer that matches their operation. A producer running 30 conventional wells with two pumpers doesn’t care about Honeywell’s refinery DCS. A horizontal operator running continuous-measurement pads doesn’t need a rod-pump POC vendor pitch. The vendor match happens at the layer match.

This page breaks down the automation vendor landscape by layer: equipment-level, well-site, field-level (SCADA), and operational (remote monitoring and pumper data capture). For each, the major players, the niche specialists, and the honest trade-offs.

Before You Pick a Vendor, Pick the Layer.

On conventional wells, the right automation spend usually isn't the SCADA stack a vendor is pitching. It's TinyPumper.

Equipment-Level Automation Companies

These vendors make the individual controllers, sensors, and mechanical automation pieces that run on specific equipment:

  • Lufkin Industries (Baker Hughes): pump-off controllers, rod pump diagnostics, and pumping unit optimization. Long history across Texas, Oklahoma, and the Mid-Continent.
  • Weatherford International: pump-off controllers, rod pump automation, production optimization systems.
  • Baker Hughes: broader production chemical and automation offerings in addition to POCs.
  • Flotek Industries: production chemical automation and related equipment.
  • Kimray: oilfield production equipment including pressure controllers, dump valves, and related automation.
  • Cameron (Schlumberger): wellhead and surface equipment with integrated automation.
  • FreeWave, SignalFire, Sutron: wireless telemetry vendors that connect equipment to telemetry networks.

Most producers buy equipment-level automation through regional oilfield supply distributors rather than directly from the manufacturer. POC budgets are typically per-well capex that gets amortized in a year or two on any well with meaningful production.

Well-Site Automation Companies

At the wellsite and tank battery level, the vendor landscape shifts toward industrial automation specialists:

  • Rockwell Automation (Allen-Bradley): PLCs, HMIs, and FactoryTalk software. A default in many oilfield RTU builds.
  • Schneider Electric (Modicon, Magelis): PLCs and automation components, with AVEVA on the software side.
  • Siemens: PLCs (SIMATIC), HMIs, and WinCC SCADA. Less common in upstream oil and gas than in manufacturing, but present in midstream and gas processing.
  • Emerson: ROC/FloBoss RTUs and flow computers, along with broader automation offerings.
  • ABB: process automation and RTUs, common in midstream applications.
  • AutoSol (Automation Solutions): oilfield-focused RTU and flow computing with SCADA integration.

Well-site automation projects are typically delivered by integrators: firms that buy PLCs and instruments from the above vendors and build out the panel and logic for the specific operator. NFM Consulting, HPS Automation, ESI, and Total SCADA are examples of integrator firms working in oil and gas.

Field-Level SCADA Companies

At the field-level (SCADA) layer of the broader automation program, the dominant platform vendors are:

  • Inductive Automation (Ignition): the SCADA platform with unlimited-tag licensing that has become a standard across Texas, the Rockies, and most major U.S. basins.
  • AVEVA (Wonderware, ClearSCADA): enterprise SCADA platforms used across upstream, midstream, and pipeline.
  • VTScada (Trihedral): Canadian-origin platform with strong adoption in Western Canada and the northern U.S.
  • GE Vernova (Proficy, CIMPLICITY): legacy industrial SCADA lines.
  • Rockwell FactoryTalk View: Rockwell’s SCADA offering, paired with Allen-Bradley PLCs.
  • Siemens WinCC: Siemens’ SCADA, paired with SIMATIC PLCs.
  • Emerson OpenBSI / Ovation: Emerson’s upstream and process SCADA platforms.

Hosted SCADA vendors serving smaller operators:

  • zdSCADA: cloud-based SCADA aimed at upstream independents.
  • SCADAfarm: managed-service SCADA.
  • Emerson Zedi: hosted SCADA and measurement services.

SCADA platform licensing is typically the smaller piece of a deployment. The bigger spend is instruments, telemetry, and integrator services. A real SCADA project is usually a six-figure capex event.

On conventional wells, SCADA vendors routinely price themselves out of the deal.

TinyPumper is the alternative: a solar-powered gateway with radar tank sensors and pressure sensors, installed in 10 minutes, pushing data over cellular or satellite. Roughly 99% of SCADA's upside. Works at 50 wells or 5,000.

Operational-Layer Automation Companies

This is the layer most vendor lists skip. It splits into two pieces: remote-monitoring hardware that fills the SCADA gap on conventional wells, and pumper-data capture software that replaces the paper-and-phone-calls workflow.

  • TinyPumper: the SCADA alternative for conventional wells. A matchbox-sized, solar-powered gateway plus radar tank and pressure sensors. Installs in about 10 minutes. Cellular or satellite. Delivers roughly 99% of SCADA’s upside without the capex, the wiring, or the ongoing IT burden. The buyer is the producer, whether the field work is handled by company pumpers or a contract pumping outfit.
  • GreaseBook: production data capture for independent producers. Pumpers log daily gauges, pressures, run tickets, and photos on iOS or Android. Executive dashboard for owners, engineers, and office staff, with state reports (Texas, Mississippi, Alabama, Wyoming, Michigan) built as the month goes. Integrates with SCADA systems and with the major oil and gas accounting platforms (OGsys, Wolfpak, Bolo, SSI, Pac Energy, P2, Quorum, W Energy).
  • WellSight: wellsite data capture and reporting.
  • Pason: drilling-focused data capture and automation services, with some production extensions.

Mid-range oil and gas accounting platforms (OGsys, Wolfpak, Bolo, SSI, Pac Energy) and the next tier up (P2, Quorum, W Energy) both ship their own bolt-on production modules. Those modules exist to serve the accounting workflow, not the field. GreaseBook integrates with these platforms rather than replacing them: production data flows in, accounting does what accounting does.

Operational automation is the layer where the deployment is fast (plug in a gateway, download an app) and the ROI is immediate because it fixes the data chain that every downstream process depends on.

How to Match Vendor to Operation

A few honest heuristics:

  • Running conventional wells where SCADA never penciled out? Start with equipment-level automation on wells that need it (POCs, plunger lifts) and TinyPumper for remote tank, pressure, and runtime monitoring. This is the same answer whether the producer runs 50 wells or 5,000. A GreaseBook pumper app on top closes the daily data chain.
  • Running aging SCADA that’s costing more to maintain than it gives back? TinyPumper is the drop-in replacement for the conventional wells in the portfolio. The legacy SCADA can stay on the wells that still justify it.
  • Running higher-rate unconventional pads with an automation team? Talk to Ignition integrators first, with AVEVA, VTScada, and AutoSol as alternatives depending on your integrator’s specialty. GreaseBook still fits as the production layer that plugs into SCADA.
  • Running midstream or compression? SCADA is a requirement, and the choice is typically driven by the platform your integrator knows best and your control room’s existing standards.

The worst outcome is matching the vendor to the marketing pitch instead of matching the layer to the operation. The best operators we see don’t chase the vendor with the loudest booth. They write down what needs to happen at the well, at the battery, and on the month-end close. Then they find the vendor whose product fits that job.

What To Avoid When Picking an Automation Vendor

Category-level mistakes, not vendor-specific. The named vendors above all have customers who are happy with them for the right use case.

  • Don’t buy the pitch that promises to replace the pumper. Every vendor’s deck at some point implies fewer boots on the ground. No current-generation automation delivers that. Tanks still need hauling, valves still fail, seasonal freezes still happen. Automation reduces the frequency of visits, not the need for them.
  • Don’t sign before a 60-to-90 day pilot at three sites. A vendor who won’t let you run a real-world pilot is telling you something about how the rollout will go.
  • Don’t mistake “we have a SCADA product” for “we fit your scale.” Enterprise platforms built for refineries don’t always scale down cleanly to conventional upstream wells. The Permian Anchor works in both directions. Confirm the vendor has customers who look like your operation, not just the ones on their logo wall.
  • Don’t buy layer number three before layer number one is working. A predictive analytics platform on top of a broken daily data chain is expensive noise.
  • Don’t skip the budget line for the person maintaining it. A vendor list is less important than whether someone on your team owns the automation after it’s installed.

Wrong Fit for This Page

If you are a procurement team at a major operator building an automation RFP list, this page is a useful starting directory but not a substitute for an integrator-led requirements process. If you are a market research analyst looking for a complete competitive matrix, this page is too focused on the operator’s decision to be useful. This page is written for independent producers (2 wells to 2,000+) trying to understand which vendor plays where in the stack, regardless of whether the field work is done by company pumpers or a contract pumping outfit.

FAQ

Why pick TinyPumper over an established automation vendor?

TinyPumper is not a competitor to a full SCADA stack on high-rate unconventional pads. It’s the alternative when the wells are conventional and the SCADA math either never worked or stopped working. Solar-powered gateway, 10-minute install, no IT team, flat rate per site. Roughly 99% of SCADA’s upside without the cost or complexity. The math holds at 50 wells and it holds at 5,000.

Who is the largest oil and gas automation company?

By revenue in broad industrial automation, Rockwell Automation, Emerson, Siemens, and Schneider Electric are among the largest. In oilfield-specific niches, Baker Hughes, Weatherford, and Lufkin are the historical equipment-level leaders, and Inductive Automation dominates the SCADA software side.

What are the top oil and gas automation companies?

Rockwell Automation, Emerson, Siemens, Schneider Electric, and ABB lead the broader industrial side. Inductive Automation (Ignition) leads the SCADA software side. AutoSol, Kimray, Lufkin, and Weatherford are common oilfield-specific names. TinyPumper is the SCADA alternative for conventional wells, and GreaseBook is the pumper-app and production-dashboard layer that sits on top of any of the above.

How do I choose an oil and gas automation company?

Match the vendor to the layer that fits your operation. Equipment-level automation vendors for specific gear; industrial automation vendors and integrators for wellsite builds; SCADA platform vendors for field-level deployments; operational automation vendors for data capture and workflow.

Where does TinyPumper fit if the producer already has legacy SCADA?

TinyPumper is the drop-in replacement on conventional wells where legacy SCADA has aged out and the cost to keep it running no longer justifies the upside. Swap sensors as they fail, move the conventional wells onto TinyPumper, and let the legacy SCADA stay on the wells that still earn their keep under it. The transition is incremental. No forklift upgrade, no “rip and replace” project plan.

About the author: Greg Archbald is the founder of GreaseBook. He built the product from inside the oil patch and has spent 15+ years on the operator side of oil and gas technology.

Most automation vendors on this list price their stacks for process plants and high-rate pads.

TinyPumper is priced for conventional wells where SCADA either never made the math work or is aging into a maintenance bill that no longer earns its keep. Same visibility, same data. A matchbox-sized gateway, a radar tank sensor, and a pressure sensor. 10-minute install. Flat rate per site.

**P.S.** The vendor you pick matters less than whether you budget for the controls engineer who keeps it alive. A lower-cost vendor with a dedicated maintainer beats a premium vendor with nobody in charge, every time.
