How do I ensure my seismic interpretation workflow with a petrophysical interpretation platform is compliant with internal data security rules?

To keep a seismic interpretation workflow compliant with internal data security rules, treat the petrophysical interpretation platform like any other controlled enterprise system and design the workflow around your policies rather than around convenience.

Here’s a practical approach:

1) Classify the data first

Identify what types of data are involved:

• Seismic volumes, horizons, faults, well logs, checkshots
• Derived interpretations and models
• Sensitive items such as well locations, reserve estimates, acquisition metadata, proprietary velocity models, or export-controlled data

Then map each data type to your internal classification scheme, for example:

• Public
• Internal
• Confidential
• Restricted / Highly Restricted

This determines who can access it, where it can be stored, and whether it can leave the approved environment.

2) Use only approved platforms and storage locations

Make sure the interpretation platform is:

• On the company’s approved software list
• Hosted in an approved environment
• Connected only to approved storage, databases, and collaboration tools

Avoid:

• Personal cloud storage
• Unapproved plugins or scripting packages
• Copying data to local drives unless explicitly allowed
• Using consumer file-sharing tools for project data

3) Apply least-privilege access

Give users only the access they need:

• Role-based access control for interpreters, geophysicists, petrophysicists, managers, and contractors
• Separate permissions for read, write, export, and delete
• Limit access by project, asset, region, and data class

Also enforce:

• Strong authentication, preferably MFA
• Timely removal of access when people change roles or leave the project
• Periodic access reviews

4) Control data movement in and out of the platform

A lot of security risk comes from exports.

Define rules for:

• File export formats
• Emailing screenshots or interpretations
• Copying to USB or external drives
• Sharing with vendors or partners
• Using offline workstations

Where possible:

• Restrict export to approved formats
• Watermark exports
• Log every download/export
• Require approval for external sharing
• Redact sensitive metadata from reports

5) Keep an audit trail

Your platform should log:

• User logins and failures
• Data imports and exports
• Interpretation edits
• Deletions
• Sharing events
• Admin actions
• Permission changes

Make sure logs are:

• Centralized
• Tamper-resistant
• Retained according to policy
• Reviewed for suspicious activity

6) Encrypt data in transit and at rest

Verify that:

• Data is encrypted when stored
• Data is encrypted when transferred between systems
• Backup data is also encrypted
• Encryption keys are managed according to corporate policy

If the workflow includes remote access, ensure secure VPN or equivalent approved access controls.

7) Segment sensitive environments

For high-value or highly sensitive interpretation projects:

• Use network segmentation
• Separate production from test/dev environments
• Restrict internet access if required
• Isolate third-party integrations
• Use secure jump hosts or bastion access for admin tasks

8) Manage third-party and vendor risk

If the interpretation platform is cloud-based or vendor-managed:

• Confirm the vendor meets your security requirements
• Review contracts, NDAs, and data processing terms
• Check data residency requirements
• Confirm incident notification timelines
• Ensure subcontractors are controlled
• Validate offboarding and data deletion procedures

9) Define a secure workflow for collaboration

If multiple teams are working together:

• Use version-controlled project spaces
• Define approval points for interpretation updates
• Separate draft vs approved outputs
• Use controlled naming conventions and metadata standards
• Avoid ad hoc sharing by chat apps or email attachments

10) Protect endpoints and workstations

Seismic and petrophysical work often happens on powerful workstations, which can be weak points.

Require:

• Company-managed devices
• Endpoint protection and patching
• Full-disk encryption
• Screen lock timeouts
• No local admin rights unless necessary
• Device compliance checks before platform access

11) Build compliance checks into the workflow

Don’t rely only on policy documents. Embed controls:

• Mandatory project creation checklist
• Data classification check before import
• Approval before external sharing/export
• Automated access expiration for contractors
• Periodic review of project permissions and data retention

12) Document the workflow

Create a standard operating procedure that covers:

• Who can access what
• Where data is stored
• How data is imported/exported
• How interpretations are approved
• How incidents are reported
• How long data is retained
• How data is destroyed at project close

13) Train users

Even good controls fail if people don’t know the rules. Train users on:

• Data classification
• Secure handling of seismic and well data
• Export restrictions
• Phishing and social engineering
• Incident reporting
• Rules for contractors and external collaborators

14) Perform regular audits and reviews

Periodically check:

• User access lists
• Export logs
• External sharing
• Policy exceptions
• Backup/restore controls
• Vendor compliance
• Retention and deletion evidence

A simple compliance checklist

Before starting the workflow, confirm:

• Data is classified correctly
• Platform is approved
• Access is role-based and reviewed
• Encryption is enabled
• Exports are controlled
• Logs are being captured
• Contractors are managed
• Device security is enforced
• Collaboration rules are documented
• Incident response contacts are known

If you want, I can turn this into:

1. a one-page internal compliance checklist,
2. a workflow diagram, or
3. a control matrix mapping seismic interpretation steps to security controls.
