Oilfield operations: articles and practical guides
Practical guides to drilling-tool history, equipment readiness, workshop handovers, field tickets, rental dates and fleet utilization.
Equipment moves between the yard, the wellsite and the workshop. Its records need to make the same journey. These guides explain what to capture, what to reconcile and which decisions the information supports.
Written for operations managers, tool coordinators, workshop supervisors, field teams and the people preparing customer invoices. Each guide includes a usable checklist, record structure or worked example, with a short explanation of the relevant Hafrix workflow.

Drilling tools and maintenance history
Mud motor maintenance history: what to record between runs follows a serialized tool through configuration changes, run records, inspection findings and workshop work. It includes an example event history and a minimum record template. Start here when a serial number is familiar but the condition and configuration behind it are unclear.
Equipment readiness and workshop handovers
Oilfield equipment pre-dispatch checklist organizes the administrative checks around identity, the requested configuration, supporting evidence, open work and the actual handover. Use it to structure a review alongside the applicable technical procedure.
Field-to-workshop equipment handover separates field observations from inspection findings and repair decisions. It includes a handover record and an example of an unresolved discrepancy that needs an owner.
Field work and commercial records
Oilfield field ticket checklist for invoice preparation explains the identifiers, quantities, approvals and attachments that make a completed job easier to reconcile. It distinguishes operating hours from billable quantities and gives a worked ticket example.
Oilfield rental delivery and return dates separates physical custody, an off-rent request, accepted commercial dates and the billing period. Follow an illustrative partial return and a record trail for a disputed collection date.
Fleet performance
Equipment utilization and readiness: read the numbers together works through a small fleet example, including a tool that is off rent but unavailable for its next job. It also explains the definitions behind Hafrix rental-utilization reports so that different measures are not confused.
About these guides
Prepared by Hafrix editorial with AI-assisted drafting and checks against the cited sources and implemented product workflows. Examples, identifiers and quantities are illustrative; they are not customer case studies or measured performance claims. Initial edition: 5 November 2026.
The guides describe operational recordkeeping. Technical acceptance, maintenance limits and site requirements come from the applicable OEM documentation, approved procedures and authorized people. A software status records the available evidence and rules; it does not establish that equipment is safe for service.
For operating instructions, use the Hafrix documentation. For a system change, see the migration guides. To follow one of these processes in the product, bring an operational example to a demonstration.
