JSON Well Log Format

Most well log and drilling data in the oil and gas industry is trapped within tapes and disk files of ancient and hard to access data formats like DLIS, LAS, LIS, BIT, XTF, WITS, ASC and SPWLA.

These formats represents orphaned  technologies and are outdated in all possible ways. Their syntax is overly complex, convoluted and awkward, available support software is limited, software tools are rare and documentation is poor or non-existent.

But still: These are the main storage and communication media for well logging information in the 2020s. The amount of data is immense and growing, as is the aggregate cost of maintaining and utilizing this information.

GeoSoft has created the JSON Well Log Format for future requirements of simplicity, compatibility, speed, massive storage, massive transmission, cloud computing and big data analytics. It overcome all of the deficiencies of existing well log formats.

OSDU - Practical Well Log Standard (PWLS)

The Practical Well Log Standard (PWLS) is one of the more promising standards to emerge from OSDU/Energistics. It contains complete lists of well tools, curves, properties, companies, logging methods etc. used in O&G exploration.

Its static nature however makes it rather impractical in use, and to mitigate this GeoSoft has devised a dynamic, version controlled (Git), cloud-based (AWS), REST API (JSON) for this standard.

The GeoSoft initiative is a Proof of Concept of how the PWLS process should be set up and maintained. We welcome collaboration from the industry in order to make it production ready.

OSDU - Unit of Measurements Standard (UoM)

The OSDU Units of Measurements (UoM) is an impressive standard, covering nearly 200 different quantities (length, pressure, temperature, resistivity, etc.) and over 2000 units (m, ft, bar, Pa, etc.), complete with conversion factors. This is a great foundation for any scientific software.

However, the standard has several deficiencies:

  • It is not publicly available as it is limited to OSDU members only
  • The definitions are convoluted, making it awkward for practical use
  • It lacks a simple reference implementation
  • Display units are not supported

The GeoSoft UoM open source project addresses all these issues. It includes a single, streamlined JSON file capturing the entire standard, and which can be easily applied to any programming environment in just a few lines of code. Best of all, this JSON file includes proper display units, allowing the use of symbols like °C, µΩ, or m³ instead of the common but less readable degC, uohm, or m3 etc.

GeoSoft provides open source reference implementations in Java, C# and Python, as well as a PoC REST API for querying this information.

Sodir I/O - Fact Pages Library and REST API

The Norwegian Offshore Directorate (Sodir) Fact Pages is an invaluable source of information for the activities in the North Sea. It contains real-time metadata and production data for 8000 wells, 4500 surveys, 1000 facilities, 800 companies and much more.

Inspecting the information through a web browser is useful, but to really get advantage of this information computerized access is essential.

The GeoSoft Sodir I/O open source library is created for providing programmatic access to the Sodir Fact Pages. The library is also exposed through a public REST API PoC to make the information easily accessible in all possible programming environments.

Projects

GeoSoft actively participates in client projects while also conducting independent research initiatives to explore new technologies and enhance established industry practices and procedures as shown below.

By developing prototype software, we empower clients to visualize potential solutions, generate new ideas, and accelerate product development. This hands-on approach not only inspires innovation but also streamlines the development process, enabling us to deliver cost-effective and tailored solutions that meet our clients' unique requirements.

WITSML

GeoSoft has worked with real-time solutions and WITSML technology since its start in 2005 and we possess deep knowledge and experience on all aspects of real-time services, both on server side, client side and in terms of working with the standards in both Energistics and OSDU.

WITSML

Log IQ™

Log IQ™ ("Logic" ) is a centralized well log server running in cloud and delivering real-time data with high frequency.

Log IQ™ is based on the GeoSoft JSON Well Log Format and has the potential to replace convoluted technologies like WITSML and ETP. Log IQ™ uses bidirectional web socket technology to achieve maximum throughput and minimum latency. All communication is done over standard internet protocols using established encryption standards.

Log IQ

Log file I/O

GeoSoft has long experience with developing access logic for industry well log formats. We possess deep knowledge on popular formats like DLIS, LIS and LAS as well as the more esoteric BIT, SPWLA, XTF and various custom versions of CSV and TXT. GeoSoft has developed generic log file parsers for various programming platforms, and we have created high performance parsers for specific purposes and needs.

WITS

WITS is a legacy transmission format that is still used on rigs for low-level communication of log data. GeoSoft doesn't do WITS because it is trendy (it is not), but because it is actually used and the industry deserves simple, modern, reliable, secure products with clean and robust APIs to handle this technology.
