Short answer: P2 Field Operator is the mobile field-capture layer of IFS Merrick, the upgrade path from eVIN. If you already run Merrick and your pumpers live in the P2 Field Operator app, keep it. If the real problem is getting clean numbers off the lease every day, GreaseBook is the better fit for that job. GreaseBook integrates with P2. If he can text, he can use GreaseBook. Average learning curve is 8 minutes.
It’s the tenth of the month. A partner wants last month’s volumes. I just want to see yesterday’s gauges without calling three guys. The pumper keys it in at home on the laptop, not standing at the well. ProCount cannot allocate what never got captured on the route.
Is P2 Field Operator or GreaseBook the Better Fit for My Operation?
It depends on where it hurts. If you already run IFS Merrick, need ProCount hydrocarbon accounting, Route Surveillance on SCADA, and Carte where that module is in play, Field Operator may be your better pick. If the problem is pumper accountability on independents running a handful of wells to over 2,000, GreaseBook does that job as of November 2026: 600+ production companies, geofenced visits, 200% money-back. Keep Merrick. Add GreaseBook when capture is the hole.
What Is P2 Field Operator?
P2 Energy Solutions bought Merrick Systems in 2014. eVIN shipped in 2003. P2 released Field Operator in 2017. IFS now sells IFS Field Operator (Pathfinder Edition) as the upgrade to eVIN (IFS datasheet and App Store listing, July 2026). Apple still lists older P2ES Field Operator and EXP Edition apps beside the IFS-branded one. If you searched P2 Field Operator alternative android or ios, those listings are the same product family.
IFS Merrick positions Field Operator for online or offline entry, low-bandwidth sync, run tickets, well tests, downtime, alerts, mapping and geolocation (IFS Merrick page and Field Operator datasheet, June 2023). P2’s April 11, 2022 release said Merrick capture was deployed by more than 22,000 field operators.
What Does IFS Merrick Do Best, and What Does GreaseBook Do Best?
| What P2 Field Operator / IFS Merrick does best | What GreaseBook does best |
|---|---|
| Field Operator plus ProCount allocation and regulatory reporting | Gauges, tickets and comments at the well |
| Route Surveillance against live SCADA | Proof of visit with geo-fencing |
| Low-bandwidth sync for 22,000 field operators (P2, 2022) | 8-minute learning curve on one iPhone/Android app |
| ESG events, inspections, maintenance transactions | State reports prepared for any oil and gas producing state |
| eVIN upgrade path inside a suite you already own | Turnkey setup and 200% money-back after 6 weeks |
On the production side specifically, a tool built only for pumpers tends to beat a suite module. That is a footnote. The thesis is integration: GreaseBook integrates with P2. Tell us on the quiz which IFS Merrick modules (ProCount, Route Surveillance, Carte) you actually run each month, and we will confirm how production data should land.
How Does GreaseBook Handle the Field Side?
GreaseBook integrates with every major oil and gas accounting platform on the market. PakEnergy (formerly WolfePak), OGsys, Bolo, SSI, P2, PHDwin, and the rest of the majors you’d expect. P2 is on that house list. SSI and P2 are separate systems. Never write them as one.
Well tests, downtime and shut-in state get recorded so allocation is not garbage-in. GreaseBook prepares state production reports for any oil and gas producing state, ready for you to review and submit. If your state’s form isn’t built yet, we build it at no cost. More in oil and gas production data management software.
Our petroleum engineers build it for you. Pumpers learn it in about 8 minutes. 200% money-back guarantee.
See if GreaseBook fitsThe Amateur vs. the Pro
| The Amateur | The Pro |
|---|---|
| Signs a Field Operator SOW because the suite already includes ProCount | Asks which IFS Merrick modules (ProCount, Route Surveillance, Carte) the company actually uses each month |
| Lets contract pumpers juggle eVIN, EXP Edition and IFS Field Operator logins | Picks one capture app the route will open; GreaseBook’s 8-minute learning curve is the other option |
| Treats “integrates with every major platform” as a hint that Merrick is confirmed | Names P2 on the house list, then confirms the Merrick feed on the quiz |
What to Avoid
- Leaving P2 off the integration list. The house list includes P2. Do not imply a Merrick feed you have not confirmed.
- Skipping geo-fence. GreaseBook geofencing is how you prove the visit. Wells slip when you cannot.
- Trading a 200% money-back guarantee for an unpublished IFS timeline. Get both in writing.
What GreaseBook Facts Should You Know?
As of November 2026, 600+ production companies trust GreaseBook with their data. 10,000+ pumpers use it in the field. GreaseBook has 15 years in the oil patch, has tracked 220 million+ barrels, and serves operators in 22 oil-producing states. The average pumper learning curve is 8 minutes. GreaseBook has a 98% operator trial success rate and a 200% money-back guarantee: run it a full 6 weeks, and if you don’t see results, we pay you double what you paid us. TinyPumper is GreaseBook’s sister product.
What Is GreaseBook Not?
GreaseBook is a production app. It does not replace ProCount or IFS as hydrocarbon accounting. It feeds clean production data to the accounting system you already run, including P2.

Frequently Asked Questions
What is P2 Field Operator?
P2 Field Operator is IFS Merrick’s mobile field-capture app, built by the same lineage as eVIN. P2 bought Merrick Systems in 2014. eVIN shipped in 2003. Field Operator shipped in 2017. The current iOS listing is IFS Field Operator, Pathfinder Edition, described as a significant upgrade to eVIN (Apple App Store, July 2026).
What is the best P2 Field Operator alternative?
If your pumpers already live in the P2 Field Operator app and ProCount is happy, stay. If you need geo-fenced visits, one iPhone and Android app, and state production reports prepared for any producing state, GreaseBook is the better field fit. Keep IFS Merrick. GreaseBook integrates with P2.
Is there a P2 Field Operator app for Android and iOS?
Yes. IFS says Field Operator works on any device, online or offline. Apple lists Field Operator, Field Operator EXP Edition, and IFS Field Operator. Confirm the Android package your Merrick admin currently licenses. GreaseBook also ships iPhone and Android, including a P2 Field Operator alternative android and ios search when the suite app is the pain.
Does GreaseBook integrate with IFS Merrick / P2?
GreaseBook integrates with P2. The house list is PakEnergy, OGsys, Bolo, SSI, P2, PHDwin and the other majors. For a specific ProCount, Route Surveillance or Carte feed, tell us on the quiz. We confirm on the spot rather than implying a connector we have not named.
Is P2 the same as SSI?
No. SSI and P2 are separate accounting systems. Never write SSI/P2. GreaseBook talks to both. P2 Field Operator IFS Merrick is the field-capture question; SSI is an accounting alternative in the PakEnergy tier.
How do I switch capture from eVIN or Field Operator to GreaseBook?
Hand our team a login to your current system. Petroleum engineers build your wells first. After pumpers check routes and a supervisor signs off, we backfill history. Most operators are fully rolled out within a week. Ask about contract buyout if you are in a term.
