Field Work Authority

          The history of oil exploration in Iraq began in the late eighties of the nineteenth century, Iraqi oil discovered by surface oil spills in Mesopotamia the first drilling of wells in the Middle East began in November 1902 at Chia Surakh in northeastern Iraq, which were abandoned in depth 2,315 feet in 1912, as the anti-stealing theory of oil foreclosures rose and became widely accepted, which is what happened in Mesopotamia.

    The application of geophysical methods in Iraq was discussed for the first time at a meeting of geological advisors to TPC (Turkish Petroleum Company) in June 1928 and a refractive survey was conducted in northern Iraq from September 1928 to June 1929 on Kirkuk, Bulkhana, the red and Hamrin structures were uncovered to determine the limestone structure Main, a major gravitational survey covering several regions of Iraq was conducted between 1940 and 1941, and in 1945, comprehensive geophysical surveys were conducted by IPC and the results used to direct the location of seismic surveys using single deep holes. The Zubair structure was the first to be determined by the Rayco gravimeter survey, a follow-up of the seismic survey in 1947 that was identified from counter-lines in the Omar and Zubayr River, and depending on the results the wells of Zubayr-1 and River Omar-1 were drilled in 1948 and 1949, respectively. In 1964 the Iraq National Oil Company (INOC) was formed to explore other areas.

      In 1970 the Iraqi National Oil Company established the "General Corporation for Oil and Gas Exploration", which was later renamed as the Oil Exploration Company (OEC). In the same year, the Iraqi seismic crew was first commissioned to use multi-faceted earthquakes. The Iraqi National Oil (INOC) digital record, and by the end of 1974 three Iraqi seismic crews were working with dynamite as a source of earthquakes in the marshes of southern Iraq and in the Western Desert, finally in the 1980s there were 12 earthquake crews working in Iraq who were trained on Work in marshes or desert terrain, some of them are from fibrosis and a seismic treatment center was established in 1981 and the seismic survey in Iraq indicated the presence of structures in eastern Baghdad, Balad, Samarra and Tikrit, according to geophysical surveys, 400 closed buildings were identified of which only 114 were excavated. Most of the Iraqi lands were surveyed using the 2D seismic survey and resulted in the exploration of many fields (Majnoon, Hilla, etc.) And in 1990 the first 3D survey was conducted at the Kifl oil field. And obtaining at least 80% of Iraqi oil production from the main drag reservoirs and limestone in the Kirkuk field and the Zubair sandstone in the Rumaila and Zubair fields.

 After 2003: -

  Seismic crews were rebuilt after 2003 due to their complete destruction during military and war operations

The seismic crew/1 was operated after 2003 and equipped with the latest 3D seismic scanning techniques in the global exploration industry and the number of seismic crews currently operating is six, five of which work using 3D seismic surveying and one working on 2D seismic survey (2D), and another works by the vertical scanning method (VSP).

 The amphibious seismic Crew/5 was formed in 2015 and this team worked on implementing a 3D survey in the (Najaf - Karbala) project, which was completed at the end of 2018, and the division continued after that. With the completion of the 3D “Saba - Luhais” project, and work is continuing on it until now.

A seismic survey was conducted for national oil companies throughout Iraq and for foreign companies operating in Iraq since 2010 with high reliability that won the satisfaction of customers.

Crews are using the most advanced systems and software in the world at the present time as follows:

- Digital recorders (428 XL) with a large number of channels amounting to (20,000) channels with control devices for recording systems.

- The use of the latest GPS survey equipment for the (LEICA) GPS system with advanced software (RC GIS, GPS SEISMIC).

- The use of the most advanced field treatment systems in the world (Geoland and Geocluster).

- The use of high-precision (NOMAD6) vibrators as a source of energy, which is the best type used in the world.

- Modern engineering equipment and transport units to support the seismic survey.

 The field work division includes eight seismic crews operating in various parts of Iraq.

The seismic crews consist of four main sections, and these sections consists of effective units that contribute significantly to the completion of the programs assigned to them.  The nature of the work of these sections may be similar to all working Crews in terms of the tasks assigned to them, but they differ in terms of the use of energy sources (dynamite, vibrators), as well as the nature of the work of the division in terms of the geographical environment in which it operates. The following is an explanation of the overall activities carried out by these sections

  • Quality Control section: -
  • Unit C: -

The Quality Control Unit is entrusted with many and complex tasks as it is the supervisory and effective authority on the quality of registrations, as well as receiving and exporting information to and from other units such as registration and surveying. These tasks include:

1- Following up the work of the survey unit and its daily update on the Geoland system.

2- Continuous reconnaissance operations to work lines and follow-up of engineering efforts.

3- Follow-up and control the quality of seismic data by the geophysicist who is present in the Scanner, and follow-up the publication of the receiving lines and check for the presence of a trace of the polar opposite during the recording, as it is replaced by another, and inform the inspection unit of the situation, if any, to fix it.

4- Monitoring the quality of seismic data and its statistical information.

5- Conducting periodic tests for the two types of vibrators (Hardwire Similarity) and (Radio Similarity), in addition to checking the number of recorded vibrations and the percentage of distortion in them, and rejecting points that exceed the controls for vibrations.

6- Preparing and exporting SPS files for the 2D Milh- Tharthar project and delivering them to the registration unit for the purpose of working on them.

7- Daily follow-up of the points recorded in the recording device, quality control and (S/N ratio).

  8- Preparing daily and monthly reports and weekly shipment and sending them to the Quality Control Department.

Area unit: -

Installing the source and receiving points, as well as re-installing some points and (COG)

  • Lifting some beams in the work area and updating the project map on the (Arc Map) program.
  • Preparing the daily plan for the work of the area unit.
  • Examine and process the field monitored data and save it on the database after verifying that it conforms to the required controls.
  • Export coordinates in the form of (SPS files) to the quality control unit.
  • Preparing detailed maps and plans and distributing them to groups (excavation, sawing and lifting, line examiners).
  • Making work progress maps for each of (power lines, receiving lines, publishing, uploading, recording)
