Data supply

NOTE! In the following procedures references are made to the official text of the Mining Act. You will find direct links to the relevant articles of the Act. Unfortunately, the official text of the Mining Act is not available in English. However, an unofficial translation in pdf format is available via our legislation page. 
 

Supply of data by licencee/operator (in general)

A copy or representative part of the data collected for the reconnaissance, exploration, production or storage of natural resources or geothermal energy must be supplied to the Minister of Economic Affairs (Article 123 of the Mining Act). A description of the data concerned and the timeframe involved is given in chapter 7 of the Mining Decree. Chapter 11 of the Mining Regulations provides further specification.
 

Data must be supplied to TNO and preferable in one of the following formats:

  • TNO SFTP-server (Apply for an account at TNO)
  • Email to rapportage-mijnbouwwet@tno.nl
  • USB-stick
  • CD/DVD


For contacts of the Geological Survey of the Netherlands - TNO see contacts. Essential post and deliver adresses can be found at the bottom of this page. 

 

Supply of geophysical data by operator

Data obtained from geophysical research for mining activities have to be submitted to TNO (MBB, art 108). Eventually the data will be relinquished ten years after the acquisition was completed.The data that will have to be supplied concerns all geophysical research (MBB 108) seismic, gravimetric, magnetic, electromagnetic or any other type of geophysical methods. All data must be supplied in a digital form. This also applies for data that is originally aquired analogue. Data supplied which are (partly) located outside Dutch territory will be considered as part of the survey and as such relinquished according to the regulations in force. The data will consist of the final processing results of signal, navigation and velocity data accompanied by the relevant reports on acquisition and processing of the field data (MBR art 11.1.1).
 
TNO has formulated a standard for the delivery of seismic data.
 
The geophysical data has to be supplied to TNO within one year after aquisition on the adress mentioned below and preferably on a USB-stick. 
 
Mining Act: article 123
Mining Regulation: article 11.1.1
 

Supply of borehole data by licencee/operator

The licensee/operator will supply borehole measurement data, tests, measurements of rock samples and the Composite Well Log aquired during the creation, use, maintenance, repair and decommissioning of the borehole. 
 
The document Borehole Data and Formats prescribes the information to be delivered and in what formats. This information must be deliverd to TNO within 12 weeks after they are obtained.
 
Mining Act: article 123
Mining Decree: article 109 and article 114
 

Delivery of rock samples by licencee/operator

The operator supplies the Minister with a representative part of the cores and rock samples obtained while constructing a borehole. These samples will be supplied within twelve weeks from the date they were obtained (for delivery address see below).
 
Rock samples will be supplied according to the following guidelines:
Drill cuttings: Preferably unwashed samples dried at a maximum temperature of 60 °Celsius. At least 250 grams per sample in intervals equal to the sample intervals as used by the company. Wet samples in properly labeled, linen-type sacks with small perforations that allow natural drying are also acceptable. 
Cores (excluding sidewall cores or portions thereof): Whole cores, segments or slabs along the full length to be supplied within one year.
Sidewall cores: Residues, if available or duplicate palynological slides are sent immediately after preparation. When no such preparation has been done within one year, TNO may apply for a representative part of the original material. 
 
Mining Act: article 123
Mining Decree: article 110 and article 114
 

Production and injection data

Based on article 123 of the Mining Act mining companies either involved in production of oil, gas or salt or involved in injecting substances for storage must report their production figures to the Dutch government.

The information mentioned in article 111 Mining Decree (Mijnbouwbesluit, MBB) are, according to article 119 MBB, also applicable to the production of geothermal energy. It primarily concerns produced quantities of geothermal energy and natural resources and the injected substances and enabling substances as described in article 111, 112 and 119 of the MBB.

The data must be submitted to TNO (as described in Article 11.4.1 MBR) within four weeks after the reported month. (art 111.2 and 112.2 MBB)

Data submittance is in a predescribed format. For Geothermal data this format is described in 'Aardwarmte Productiecijfers' (In Dutch, version december 2016) and in the following pdf-document 'Aanlevering productiegegevens aardwarmte' (In Dutch, version 2016). This spreadsheet also contains an export function to convert the data to an xml format which can subsequently be emailed to TNO (rapportage-mijnbouwwet@tno.nl).
 For oil, gas and salt the procedure is described in the Excel spreadsheet ‘Template Report Mijnbouwbesluit.xls’.

Oil, Gas and Salt
The following data has to be supplied for oil gas and salt production and storage

Production:

  • per borehole: the quantities produced and types of minerals;
  • per licence area: the quantities and types of minerals removed;
  • per mining work: the quantities and types of minerals consumed;
  • per mining work: the quantities and types of minerals destroyed;
  • per borehole: the quantities of substances other than minerals produced;
  • per borehole: the quantities of substances brought into the subsoil for the purpose of production.
     

Storage

  • per reservoir: the quantities and types of substances stored;
  • per reservoir: the quantities and types of substances retrieved and removed;
  • per mining work: the quantities and types of substances retrieved and consumed,
  • per mining work: the quantities and types of substances retrieved and destroyed.

 

Geothermal energy
Per well:

  • The amount of water produced (m3)
  • Average temperature of the produced water, weighed per volume, measured prior to the heat exchanger (°C)
  • Average pump pressure of the pump in the production well (bar)
  • Maximum pump pressure in the pump in the production well (bar)
  • Amount of oil produced from the aquifer through the production well (Sm3)
  • Amount of gas produced from the aquifer through the production well (Nm3)
  • Amount of condensate produced from the aquifer through the production well (Sm3)
  • Amount of inhibitor that remained in the production well (liter)
  • Amount of injected water (m3)
  • Average temperature of the injection water, weighed per volume, measured between the heat exchanger and the well head (°C)
  • Average pump pressure of the pump in the injection well (bar)
  • Maximum pump pressure in the injection well (bar)
  • Amount of injected inhibitor in the injection well (liter)


Per facility:

  • Heat withdrawn from the primary circuit (MJ)
  • Number of operational hours of the primary circuit (hour)
  • Used electricity for the primary circuit (Kwh)

 

Relinguishment of production and injection figures
Production and injection figures submitted according to articles 111, 112 en 119 MBB are relinguished following article 116.1MBB four weeks after the term for submitting the data.

Data is released on the NLOG portal. All the other data is treated according to article 10.1.c Wet Openbaarheid van Bestuur, as described in article 123.3 of the Mining Act.
