TMK Pipe Solutions at Complex Fields in Azerbaijan

19.08.2021       

In July, Azneft Production Association (part of the State Oil Company of Azerbaijan SOCAR) commissioned a high-yield well on one from the most complex deposits "Bulla-Deniz".
The well under project number 123 has a depth of 6153 meters. The project is important for Azerbaijan's gas balance by the end of July 2021, the well reached the average daily flow rates: ≈550,000 - 600,000m³ of gas and ≈110 tons of condensate.
Well No. 123 used tubing with premium connection from world leader OCTG of the Russian company PJSC "TMK". The total length of the tubing string is 5820 meters.

The representative of PJSC "TMK", who is directly in charge of the project, Avtandil Mammadov notes: "We are satisfied with the level of interaction between Azneft and TMK" and the expected effect of trouble-free operation of TMK premium pipe solutions in superdeep wells of Azerbaijan. We are glad that we are part of the success of the State Oil Company of Azerbaijan in increasing gas production and reducing the total normalized cost per unit of hydrocarbons produced.
The choice of TMK premium pipe solutions, in addition to the tasks mentioned above, will help solve the tasks of tomorrow. Close interaction between PJSC "TMK" and the end user of our innovative piping solutions is able to meet the challenges of the future. The immediate prospects in the oil and gas sector — reduction of the carbon footprint of produced fuel.
The double-row tubing string at well No. 123 has a length of 5820 meters and a total weight of 98 tons. According to the calculations of the scientific team of the Ural State Technical University under the guidance of Professor V. G. Lisienko, the through emission of CO₂ to obtain a billet for pipes is about 1100-1150 kg per ton of such products. End-to-end emissions are understood as the sum of CO₂ emissions that consistently occur in all processes of the technological chain, from the extraction of raw materials to the primary production of metallurgy.
Further production of seamless pipes from steel billets, heat treatment, threading, transportation to the end user associated with end-to-end emission of CO₂ on the same scale, if not more. There is a salt trail for OCTG threaded pipes 2.2-2.3 tons CO₂ for each ton of pipe. Soon for every ton of CO₂ have to pay the so-called carbon tax. Based on today's European Emissions Trading Scheme (EU ETS) rates, the tax would be at least 35 euros per tonne.
Increasing the overhaul period will ultimately help save the cost of the prospective tax, since the through emission of CO₂ for hydrocarbon raw materials will be calculated based on all components of the technological chain, from drilling to production.
are aimed at a significant increase in the overhaul period of wells. This, in addition to the usual tasks of trouble-free operation, will help solve the problem of tomorrow — reducing the carbon footprint of produced oil and gas.
