Use Your Rod-Lift Wells in Codex
Add PetroBench to your Codex config. Codex can then find wells, read equipment, and run RodSim simulations with the permissions you already have.

Connect Codex in Two Steps
Codex reads MCP servers from its config file. Sign-in opens in your browser.
MCP access is off by default. Your PetroBench account team turns it on for your organization.

Try These on Your Wells
Start by asking Codex to list your wells. If it returns wells from your organization, the connection works. Then pick a job below.

PERM-4821 shuts down on gearbox overload alarms. What is the root cause?
-

validate-well-data -
get-well-production
Peak torque is at 94% of the gearbox rating at 5.0 SPM. The last fluid shot puts pump fillage at 71%, and the card shows fluid pound on the downstroke.

PERM-4821 is having its rods pulled for offset frac protection. Based on last month's average production, use RodSim to see if we can downsize the pump to 1.75 in or 1.5 in.

get-well-production -
execute-simulation -
compare-simulations
Both sizes make the 200 bfpd target. The 1.75 in pump drops gearbox load from 96% to 86% at 7.1 SPM. The 1.5 in pump needs 9.2 SPM and gains little, so 1.75 in fits best.

1,038 of 1,221 cases stay inside the limits. Gearbox load causes most failures, above 5.5 SPM at low pump intake pressure.

PERM-4821 and PERM-1190 run closest to their limits. PERM-3304 is third at 86%.

Connecting Codex
Short answers for engineers and IT.
No. Codex signs in with OAuth. You approve the connection on the PetroBench consent screen in your browser.
No. MCP access is off by default. Your PetroBench account team turns it on when your organization asks.
Only what your role and the approved scopes allow, inside your organization. Without write scopes, Codex never sees write tools.
Only with write scopes that you tick when you connect. AI clients can make mistakes, so review any change before you confirm it, and keep write access to the users who need it.
Open Settings > Connected Apps in PetroBench and disconnect it. To change scopes, disconnect and connect again.
