Specialist Services

Troika provides expert consultancy services to support specific seismic data management projects. Combinations of software modules – optionally including customised add-ons and tailored automated workflows – can be assembled, installed in the user’s facilities, and supported as required. Leveraging decades of specialised industry experience, customised modular in-house or hosted training courses can be provided addressing topics such as legacy and modern seismic tape media and formats and the efficient use of data management software.

Troika has built a range of capabilities for independent 3rd party quality control of legacy data transcription and life-of-field seismic (LoFS) 4D acquisition. QC of transcription projects is typically based on checking a representative sample of input and output tapes, database accuracy and reliability, and expert analysis of the transcription procedures. For LoFS acquisition projects, Troika provides independent 3rd party services to remotely measure repeatability between surveys through a responsive interface to QC attributes. Versatile automated software workflows running 24/7 via remote transfer of data to and from vessels or rigs enable in-time response to E&P companies in the event of discrepancies between planned and actual survey parameters. This service can be particularly valuable when operators use different acquisition suppliers from one 4D survey to the next.

Training

Troika International provides software and specialist services for transcription and pro-active Data Management procedures and processes.

The Troika team have worked in transcription and Data Management for many years and have developed training courses to hand this knowledge over.

Training Courses

Within the industry, knowledge is often lost due to retirement and career progress. Troika’s training will assist in providing expert knowledge in the field of seismic data formats and media.

Troika’s tailored training courses can be provided either in group sessions or on a one-to-one basis. The training can be held at our training facilities in Tunbridge Wells or Houston, at your preferred location or remotely via virtual services. The courses can be offered in bitesize chunks or in-depth sessions, working around your schedule and specific requirements.

Seismic Data Management Training

  • Induction course to seismic data
  • SEGD format and its revisions
    • SEGD / _r1 / _r2 / _r2.1 / _3.0 / _3.1
  • SEGY format and its revisions
    • Textual, binary and trace header
    • SEGY / _r1 / _r2 / _r2.1 (the proposal)
  • Non-standard formats

Troika offers modular training courses addressing issues including the basics of the seismic data lifecycle, current and legacy media, data structure, and formats as well as theoretical and practical methods for quality control and reporting.

Data Management Workflows

  • Quality control and attribute visualisation
  • Extract and condition metadata
  • GIS-ready
  • Navigation merge
  • Disk data trawling and library modernisation
  • Automated workflows
  • Preparation for workstation loading
  • Identification of potential duplicate files
  • Troika predefined and user workflows

Teaching modules also cover the fundamentals for 2D and 3D data loading and are supported by hands-on practical sessions using a variety of input media. Troika also offers training in the efficient use of its software to optimally meet the specific requirements of transcription, analysis, and related projects.

Media

  • 9 track
  • 21 track
  • 3480
  • 3490
  • Exabyte
  • 3590
  • 3592
  • LTO
  • DLT

Leveraging decades of specialised industry experience, courses can be provided addressing topics such as legacy and modern seismic tape media and formats.  Modules will also cover the readability of tapes and how to recover data to ensure that any transcription work carried out maximises the recovery of legacy information.  Troika also provide courses for data transcription QC and verification of datasets for processing and loading to workstations.

Consultancy

Troika provides support from industry professionals experienced in seismic issues ranging from acquisition, data loading, processing, and uploading to workstations for analysis and interpretation. Troika’s experts will take a pragmatic approach to address your particular seismic data management challenges and will make practical recommendations to ensure the long-term sustainability of your valuable data assets.


QC and Validation

Troika software provides efficient tools to ensure that seismic datasets are contract-compliant and adhere to the guidelines set by the SEG Technical Standards Committee. It can also help in adapting processing workflows to provide exploration and production (E&P) operators and other users with more fully and accurately populated datasets. Troika also has the expertise and knowledge to provide advice and support to companies embarking on tape transcription projects by helping in the formulation of tenders, evaluating bids, and offering third party QC on the resulting data and processes. This service helps data owners to have increased confidence that their data transition has been managed correctly and securely.


Life-of-Field (LoF)

Case Study

For LoF acquisition projects, Troika provides solutions to remotely measure repeatability between surveys through a responsive interface to QC attributes. Versatile automated software workflows running 24/7 via remote transfer of data to and from vessels or rigs enable in-time response to E&P companies in the event of discrepancies between planned and actual survey parameters. This service can be particularly valuable when operators use different acquisition suppliers from one 4D survey to the next.

The scope of work
  • To provide near real time QC as the data is acquired
  • A 350MB SEG-D shot record is delivered to the Troika disk every 11 seconds
Troika’s Solution

Troika provided a web browser-based dashboard showing the planned, live & historic information:

  • Shot header information
  • First break images
  • Near offset amplitude images
  • Pre-planned vs live vessel location
  • Source statistics (gun pressure)
  • Aerial and 3D RMS plots

Once the line was completed the shots were then archived to tape in sequence

Troika's understanding of seismic data is second to none

The Troika team has been involved with the SEG Technical Standards Committee since 1999. Members including Bob Firth, Jill Lewis and Victor Ancira have been driving the development, review and ratification processes of modern industry standards such as SEG-Y 1, SEG-Y 2, SEG-D 2.1, SEG-D 3 and SEG-D 3.1. The result is we understand seismic data recording formats better than any other company.
