Kazakhstan plans to increase crude oil exports via the Baku-Tbilisi-Ceyhan pipeline in April. While this adjustment is not large in absolute terms, it again highlights Astana's ongoing commitment to diversifying its export routes amid repeated disruptions from geopolitical and logistical risks.
According to the information you provided from Reuters, two industry insiders stated that Kazakhstan plans to raise the crude oil shipments through the BTC pipeline to 140,000 to 150,000 tons in April, up from 124,500 tons in March, reflecting an increase of approximately 16%. About 120,000 tons of this volume will come from the Tengiz oil field, operated by Tengizchevroil, led by Chevron, with the remainder supplied by the Kashagan field. The insiders did not specify the direct reason for the increased shipments, but this move comes as Kazakhstan continues to strengthen alternative export routes.
The Background is Not Simple
The strategic importance of the BTC pipeline lies in its function as an alternative route that bypasses the Russian Black Sea export system. BP discloses that this pipeline, stretching approximately 1,768 kilometers, has a current transport capacity of about 1.2 million barrels per day. It traverses Azerbaijan and Georgia from the Caspian region, finally reaching the Turkish Mediterranean port of Ceyhan. For a landlocked oil-producing country, this offers a politically safer and relatively geopolitically viable alternative corridor.
Kazakhstan's most sensitive variable right now remains its significant reliance on the CPC system. As reported by Reuters on April 7, the CPC terminal processes about 80% of Kazakhstan's oil exports. Earlier this week, Russia claimed that Ukraine attacked related loading facilities in Novorossiysk. Although the Kazakh Energy Ministry stated that exports through CPC remain stable, such risk events themselves are sufficient to fortify Astana's motivation to continue allocating resources to alternative routes like the BTC pipeline.
Recovery in Supply Offers Operational Leeway
Another practical premise for the increased supply through BTC in April is the recovery of production at the Tengiz oil field following an early-year power outage incident. Reuters reported on March 24 that Kazakhstan's Energy Minister stated the country's oil production had fully recovered after previous CPC disruptions and Tengiz electricity outages; Reuters also reported in February that Tengiz had gradually restored production after a power outage in January, enabling the refocusing of export capacity towards alternative routes like BTC. In other words, this increase in supply is not only about transportation options but also directly related to the resumed normal operations of the major upstream oil fields.
Small in Volume, but a Clear Signal
In terms of volume, this increment has limited direct impact on the global oil market. In the first half of 2025, Kazakhstan's total exports through BTC were about 785,000 tons, equivalent to around 34,000 barrels per day; in comparison, the full capacity of the BTC pipeline is 1.2 million barrels per day, while the CPC carried about 1.53 million barrels per day of Kazakh oil last year. This means Kazakhstan’s share through BTC remains a small fraction of its overall export system. What truly attracts market attention is not how much is increased this time, but whether Astana will continue to elevate BTC from a "supplementary route" to a more strategic diversion channel in the long term.
What to Watch Next
In recent months, Kazakhstan has repeatedly increased its shipments via BTC after disruptions to CPC. Reuters reported in December last year that Kazakhstan raised the BTC shipment volume by about 30% for that month following capacity constraints caused by a drone attack at the CPC Black Sea terminal and plans to continue enhancing related capacities in 2026; Reuters also mentioned in July last year that further increases are still constrained by the capacity of the Aktau Port and the quality standards of BTC oil. This implies that if Kazakhstan wishes for BTC to handle a higher proportion of its exports, the subsequent key factors will not only be geopolitical conditions but also whether port expansion, trans-Caspian capacity, and mixed oil standards can keep pace simultaneously.
