PROJECT OVERVIEW
Abraj provides job-based oil well services under rate contracts. Field operations previously relied on Excel sheets to report job data, manually converted into SAP Service Orders at the head office — a process prone to discrepancies, incorrect billing, and delays, worsened by unstable site connectivity.
Callippus built the Field Ticket (FT) application to automate capturing and reporting of job logs, client satisfaction reports, and field tickets — working online and offline, syncing automatically when connectivity resumes.
THE CHALLENGE
Manual, error-prone reporting
Field data was captured on Excel sheets and manually re-entered into SAP, creating discrepancies and billing errors.
Unstable site connectivity
Remote well sites had inconsistent internet access, making real-time reporting unreliable.
Slow approval workflows
Ticket approvals lacked a structured, trackable process.
OUR SOLUTION
Offline-First Field App
Captures job logs and field tickets locally, syncing automatically when connectivity returns.
Automated SAP Integration
Completed tickets post directly to SAP, auto-generating Supply Orders.
Workflow Engine
Manages ticket approvals through a structured, trackable process.
Client Satisfaction Reporting
Digital capture of client satisfaction data alongside job logs.
