Oil and Gas Fleet Management in India:
GPS, Fuel Monitoring & Safety Guide

Why Oil and Gas Fleet Operations Need Better Visibility

Oil and gas transportation can involve tankers, service trucks, utility vehicles, maintenance vehicles and other commercial assets operating across multiple locations.

Unlike a fleet working from one local depot, these vehicles may travel long distances and spend significant time away from direct supervision.

Common operational challenges include:

• Limited visibility into vehicle movement
• Long-distance trip monitoring
• Route deviations
• Unplanned stoppages
• High fuel consumption
• Unusual fuel activity
• Excessive idling
• Driver safety concerns
• Vehicle downtime
• Maintenance planning
• Underutilized assets

Managing these issues separately creates fragmented information.

A connected fleet-management approach brings location, vehicle, driver and operational data together so fleet managers can investigate what is happening more efficiently.

What Should an Oil and Gas Fleet Manager Monitor?

Tracking every available data point does not automatically improve fleet performance.

Fleet managers should focus on information connected to real operational decisions.

Important areas include:

Vehicle Location and Movement

Know where active vehicles are and whether they are moving, stopped or inactive.

Trip Progress

Monitor whether vehicles are progressing toward planned destinations and identify significant delays.

Fuel Activity

Review fuel consumption, refuelling events and unusual fuel-level changes where compatible monitoring hardware is installed.

Driver Activity

Identify recurring behaviours such as speeding, harsh braking, harsh acceleration or excessive idling.

Vehicle Health

Monitor maintenance schedules and available vehicle diagnostic information.

Operational Exceptions

Prioritize events that require action instead of overwhelming fleet teams with unnecessary alerts.

This creates a more practical operational dashboard.

GPS Tracking for Oil and Gas Fleets

GPS tracking provides the location foundation of connected fleet operations.

Instead of relying entirely on driver phone calls, fleet managers can monitor vehicle movement through a centralized platform.

Useful information can include:

• Current location
• Previous route
• Trip distance
• Vehicle movement
• Stops
• Arrival time
• Departure time
• Route deviations

Consider a tanker travelling between a distribution terminal and a customer location.

The operations team can follow:

Vehicle dispatched

→ Trip starts

→ Vehicle follows planned route

→ Unexpected stoppage occurs

→ Operations team reviews location

→ Vehicle continues

→ Destination reached

This creates greater visibility throughout the trip.

Go Beyond Vehicle Location with Real-Time Fleet Visibility

Knowing a vehicle’s GPS coordinates answers only one question:

Where is the vehicle?

Fleet managers often need more context.

Real-time fleet visibility can help answer:

• Is the vehicle moving?
• Has it stopped?
• How long has it been stationary?
• Is the trip progressing normally?
• Has the vehicle left its expected route?
• Has an operational alert been generated?

This changes vehicle tracking from a simple map function into an operational management tool.

For fleets with vehicles spread across multiple locations, this broader view can help teams prioritize the vehicles that actually need attention.

Use Geofencing Around Important Fleet Locations

A geofence is a virtual boundary around a physical location.

For oil and gas operations, geofences can be created around areas such as:

• Terminals
• Depots
• Loading points
• Unloading locations
• Customer facilities
• Workshops
• Project sites
• Restricted operating areas

Fleet managers can then review vehicle entry and exit activity.

Example

A vehicle arrives at a terminal.

The system records:

Geofence entry

→ time at location

→ geofence exit

This can help managers understand:

• Arrival time
• Departure time
• Dwell time
• Unexpected site visits
• Delayed loading or unloading

Geofencing therefore provides operational context around location data.

Fuel Monitoring for Better Cost and Consumption Control

Fuel is one of the most important operating costs for many heavy commercial fleets.

But total fuel expenditure alone does not explain why costs are increasing.

Fleet managers need to look deeper.

Depending on the vehicle, tank configuration, sensor and integration, fuel monitoring may provide information such as:

• Recorded fuel level
• Refuelling activity
• Significant fuel drops
• Fuel history
• Consumption trends
• Vehicle-wise fuel behaviour

This information can help identify which vehicles or events require further investigation.

Monitor Refuelling Activity

A significant increase in recorded tank level can indicate a refuelling event.

Fleet teams can review the event alongside:

• Vehicle
• Location
• Date
• Time
• Trip history

This creates a more structured fuel record.

Rather than looking only at monthly fuel bills, managers can understand fuel activity at the vehicle level.

Investigate Unexpected Fuel Drops

An unexpected reduction in recorded fuel level may require attention.

Possible causes can include:

• Fuel removal
• Leakage
• Maintenance activity
• Sensor behaviour
• Vehicle operating conditions

A fuel-level change alone should not automatically be treated as evidence of theft.

A stronger investigation process is:

Unexpected fuel drop

→ Check vehicle location

→ Check whether vehicle was moving or stationary

→ Review the event time

→ Compare fuel history

→ Review operational context

→ Investigate where necessary

This gives fleet managers more information before making a conclusion.

Track Fuel Efficiency by Vehicle

Fuel monitoring should not focus only on theft or fuel loss.

Fuel efficiency can provide a broader view of fleet performance.

A basic formula is:

Fuel Efficiency = Distance Travelled ÷ Fuel Consumed

For example:

Distance travelled = 1,800 km

Fuel consumed = 300 litres

Fuel efficiency:

1,800 ÷ 300 = 6 km/L

The number should be evaluated in context.

Compare:

• The same vehicle across different periods
• Similar vehicles
• Similar routes
• Comparable loads
• Similar operating conditions

Avoid applying one mileage benchmark to every vehicle.

Heavy trucks, tankers and support vehicles can have very different operating profiles.

Measure Fuel Cost Per Kilometre

Fleet managers can also calculate how much fuel expense is generated for every kilometre travelled.

Formula:

Fuel Cost per KM = Total Fuel Cost ÷ Total Kilometres

Example:

Monthly fuel expenditure = ₹1,65,000

Distance travelled = 11,000 km

Fuel cost:

₹1,65,000 ÷ 11,000 = ₹15/km

If the number begins increasing, investigate:

• Fuel efficiency
• Idling
• Route distance
• Fuel price
• Driver behaviour
• Vehicle condition

This makes fuel data more actionable.

Reduce Avoidable Idling

A vehicle does not need to travel to consume fuel.

An engine running while stationary can increase fuel consumption without increasing productive distance.

Fleet managers can review:

• Total idle duration
• Frequent idle locations
• High-idling vehicles
• Recurring driver patterns

Some idling may be operationally necessary.

The objective is therefore not zero idling.

It is identifying avoidable idling that adds cost without providing operational value.

Monitor Route Deviations and Unplanned Stops

Not every route deviation is a problem.

Traffic congestion, road closures or customer instructions can require a driver to change route.

However, repeated or unexplained deviations should be visible to fleet managers.

A practical workflow is:

Route deviation identified

→ Review current vehicle location

→ Compare planned and actual route

→ Check stoppage information

→ Contact driver when required

→ Record the reason

This creates accountability without treating every deviation as an incident.

Improve Driver Safety Through Behaviour Monitoring

Driver behaviour has a direct relationship with fleet safety and can also influence operating costs.

Connected systems may identify events such as:

• Speeding
• Harsh acceleration
• Harsh braking
• Excessive idling

The purpose should not be to punish drivers for every event.

Fleet managers should look for patterns.

Example Driver Safety Workflow

Repeated speeding events occur.

→ Identify the vehicle and driver

→ Review route conditions

→ Check event frequency

→ Discuss the pattern with the driver

→ Provide coaching where needed

→ Monitor future performance

This turns driver data into an improvement process rather than simply another alert.

Add Video Context with Fleet Dashcams

Telematics can show that an event occurred.

Dashcam footage can help explain what happened around it.

Consider a harsh-braking event.

Fleet data may show:

• Vehicle
• Time
• Location
• Speed
• Driver

Available dashcam footage can provide visual context.

This can support:

• Incident investigation
• Driver coaching
• Accident review
• Dispute assessment
• Fleet safety analysis

Video and telematics therefore work best when used together.

Build Preventive Maintenance Around Vehicle Usage

Unexpected breakdowns can reduce fleet availability and disrupt planned trips.

Preventive maintenance helps fleets schedule service before predictable problems become failures.

Maintenance planning may use:

• Kilometres travelled
• Engine hours
• Time intervals
• Previous service history
• Vehicle condition
• Manufacturer recommendations

Typical maintenance areas include:

• Engine service
• Brake inspection
• Lubrication
• Tyres
• Suspension
• Fluids
• Electrical systems
• Safety equipment

A consistent maintenance program supports vehicle availability and long-term operating control.

Use Engine Hours Where Kilometres Do Not Tell the Full Story

Some vehicles can accumulate significant engine use while travelling relatively little distance.

Examples include vehicles experiencing:

• Long stationary operations
• Heavy idling
• Slow-moving site activity
• Extended loading or waiting periods

Where engine-hour information is available, fleet managers can combine:

Kilometres travelled

Engine hours

Maintenance history

This can create a better picture of actual vehicle usage.

Use CAN Bus Data for Deeper Vehicle Insights

Modern commercial vehicles generate information through electronic control systems.

Where vehicle compatibility and integration allow, CAN Bus monitoring may provide data such as:

• Engine RPM
• Engine hours
• Coolant temperature
• Engine load
• Diagnostic information
• Fuel-related parameters

Available parameters vary by vehicle manufacturer and model.

Fleet managers should therefore confirm which data is accessible rather than assuming every vehicle provides the same information.

CAN Bus data can complement GPS and telematics by adding vehicle-level operating context.

Monitor Tyre Condition as Part of Fleet Reliability

Tyres influence several areas of commercial fleet performance:

• Safety
• Fuel consumption
• Vehicle availability
• Maintenance cost

Where suitable tyre-pressure monitoring systems are installed, fleets may be able to monitor abnormal pressure conditions and temperature.

However, digital monitoring should complement—not replace—regular physical tyre inspection.

The most effective approach combines technology with good maintenance practices.

Measure Vehicle Utilization

A fleet can own many vehicles while still operating inefficiently.

Vehicle utilization helps managers understand whether available assets are being used productively.

A simple calculation is:

Vehicle Utilization Rate = Productive Vehicle Time ÷ Available Vehicle Time × 100

Low utilization may indicate:

• Excess vehicle capacity
• Poor allocation
• Uneven dispatching
• Vehicle downtime

Extremely high utilization can also create challenges if maintenance windows are consistently delayed.

The goal is not simply maximum use.

It is appropriate utilization with sufficient vehicle availability and maintenance time.

Track Empty Kilometres

A vehicle may be moving without carrying a productive load.

Those kilometres still consume:

• Fuel
• Tyres
• Maintenance life
• Driver time

A useful formula is:

Empty KM % = Empty Kilometres ÷ Total Kilometres × 100

For example:

Total distance = 10,000 km

Empty distance = 1,500 km

Empty kilometres:

1,500 ÷ 10,000 × 100 = 15%

Monitoring this metric can help operations teams identify opportunities for better dispatch and return-trip planning.

KPIs Oil and Gas Fleet Managers Should Monitor

A good fleet dashboard does not need dozens of unrelated numbers.

Focus on metrics tied to actual operational decisions.

The most useful comparison is usually not a generic industry number.

Compare:

Vehicle vs its previous performance

or

Vehicle vs similar vehicles performing similar work

That provides a more meaningful internal baseline.

Turn Fleet Alerts Into Operational Workflows

More alerts do not automatically produce better fleet management.

Fleet managers need a clear response process.

Fuel Exception

Unexpected fuel activity

→ Review fuel history

→ Check vehicle location

→ Check movement status

→ Investigate if required

Route Exception

Unexpected route deviation

→ Check location

→ Review route

→ Contact driver when necessary

→ Record reason

Driver Exception

Repeated safety event

→ Review driver history

→ Check operating context

→ Provide coaching

→ Monitor future trend

Maintenance Exception

Vehicle reaches service threshold

→ Schedule service

→ Complete inspection

→ Record maintenance

→ Return vehicle to operation

This is the difference between collecting fleet data and using fleet data.

How Telematics Connects Fleet Operations

Different fleet technologies answer different questions.

GPS Tracking

Where is the vehicle?

Geofencing

Has it entered or left an important location?

Fuel Monitoring

What is happening with vehicle fuel?

Driver Monitoring

How is the vehicle being driven?

CAN Bus Integration

What vehicle operating data is available?

Dashcam

What happened visually around an event?

Maintenance Management

When does the vehicle require attention?

Telematics can bring these information sources into a more connected operational environment.

The value is not simply having more data.

The value is understanding how different events relate to each other.

How Diselmap Supports Oil and Gas Fleet Operations

Diselmap provides connected fleet technologies designed to improve visibility across vehicles, drivers, fuel activity and fleet operations.

Depending on vehicle requirements and available integrations, fleets can use capabilities such as:

• GPS tracking
• Fleet telematics
• Fuel monitoring
• Geofencing
• Driver behaviour monitoring
• Real-time fleet visibility
• Dashcam and 360° camera solutions
• Preventive maintenance management
• CAN Bus integration
• Tyre-pressure monitoring
• Fleet alerts and reporting

Instead of viewing each system separately, fleet managers can use connected information to investigate operational problems.

For example:

Fuel operating cost increases

→ Compare fuel efficiency

→ Review idling

→ Check route distance

→ Identify high-cost vehicles

→ Investigate causes

Or:

Vehicle availability falls

→ Review downtime

→ Check maintenance history

→ Identify recurring issues

→ Improve maintenance planning

This creates a more structured approach to fleet management.

A Practical Fleet Monitoring Strategy

Oil and gas operators do not need to implement every fleet technology at the same time.

Start with the operational problem.

Step 1: Identify the Problem

Examples:

• Poor vehicle visibility
• High fuel consumption
• Unexplained fuel activity
• Excessive idling
• Driver safety
• Frequent breakdowns
• Route deviations

Step 2: Identify the Required Data

For high fuel costs, for example, useful data might include:

• Fuel expense
• Kilometres
• Fuel efficiency
• Idling
• Routes
• Vehicle condition

Step 3: Connect the Relevant Vehicles

Deploy suitable hardware and integrations according to fleet and vehicle requirements.

Step 4: Configure Important Exceptions

Prioritize alerts that require operational action.

Step 5: Assign Responsibility

Decide who reviews:

• Fuel events
• Safety alerts
• Maintenance requirements
• Trip deviations

Step 6: Measure Improvement

Compare performance over time rather than relying only on one-time results.

This makes technology part of a continuous fleet-improvement process.
