The Norwegian Petroleum Directorate (NPD) maintains a comprehensive database of the activities in the North Sea. This is public real-time information updated on a daily basis and made public through the NPD fact pages.

The NPD database contains information on more than 7500 wells, 4000 surveys, 120 fields, 1000 facilities, 700 companies, 1200 licenses and more.

NPD I/O is a Java library for accessing this information through a clean and simple to use Java API. NPD I/O is available for Java (NpdIo.jar). The library is lightweight (< 0.1MB) and self-contained; It has no external dependencies. NPD I/O access data directly through HTTP - no login or password is required.

NPD I/O web page: https://petroware.no/npdio.html

Capture the NPD I/O code to local disk by:

$ git clone https://github.com/Petroware/NpdIo.git

NPD I/O has no external dependenies.

NPD I/O can be built from its root folder by

$ make clean
$ make
$ make jar

The NPD I/O delivery will be the ./lib/NpdIo.jar file.

Building with make requires the make module of the tools repository.

Public Javadoc: https://petroware.no/npdio/javadoc/index.html

Javadoc can be created locally by:

$ make javadoc

Entry point will be ./docs/index.html.

Note the ./overview.html page that becomes part of the Javadoc.

Note also that there is some Javadoc configuration in ./Makefile. The Javadoc is not automatically date stamped. The Javadoc date (current month) is specified in the Makefile.

NPD I/O access data through HTTP. As the URL for each data may change over time, they are nor built in to the library, but should be provided by the client application.

Below are the correct URLs for each data type:

Below are a few examples on how to access some of the main data types from the NPD database.

   import no.petroware.npdio.field.*;
   import no.petroware.npdio.well.*;
   :

   //
   // Read development NPD wellbores
   //
   String url = "http://factpages.npd.no/..."; // Use NpdDevelopmentWellbore link from table above
   List<NpdWellbore> npdWellbores = NpdWellDataReader.readDevelopmentWellbores(url);

   // Loop over the wellbores and write to stdout
   for (NpdWellbore npdWellbore : npdWellbores)
     System.out.println(npdWellbore);

   :


   //
   // Read NPD fields
   //
   String url = "http://factpages.npd.no/..."; // Use NpdField link from table above
   List<NpdField> npdFields = NpdFieldReader.readFields(url);

   // Read production data for all fields
   String url = "http://factpages.npd.no/..."; // Use NpdProduction link from table above
   ProductionReader.readProduction(url, npdFields);

   // Loop over the fields and write oil production to stdout
   for (NpdField npdField : fields) {
     Production production = field.getProduction();

     for (Production.Entry productionEntry : production.getEntries()) {
       int year = productionEntry.getYear();
       int month = productionEntry.getMonth();

       double oilProduction = productionEntry.getOil();

       System.out.println("Oil production: " + year + "/" + month + ": " + oilProduction);
     }
   }

   :

Note that in an actual client implementation the reading process would better be done asynchronous in threads. The NPD I/O library is all thread-safe.

NPD I/O includes Java implementations for the NPD data types wellbore, license, field, company, survey, facility, discovery, business arrangement area, pipeline and stratigraphy.
