BAKU, Azerbaijan, September 17. The
Azeri-Chirag-Guneshli (ACG) Caspian field block development project
has helped bp strengthen itself as a technology company, the bp’s
publication (ACG operator) on the eve of celebrating the 30th
anniversary of the ACG contract reads, Trend reports.
“Numerous new technologies from bp have been effectively
implemented in ACG operations and development projects in
Azerbaijan, with some being utilized for the first time in the
Caspian Sea,” the information notes.
One of the bright ideas on the table is vertical drilling (ERD),
which lets target wells be set up a good ways off from the
platform, thus boosting production potential to new heights.
“The longest ERD well we have drilled so far is 6.4 kilometers
from the Chirag platform. We believe this technology will allow us
to maximize production from ACG for decades to come,” the
publication emphasizes.
Other crucial technological solutions involve drilling at a
steep angle (nearly horizontal), which allows the wells to be
wrapped up with a thinner formation, thus boosting their
productivity.
“We believe that the “bp Well Advisor” used at ACG provides
safe, reliable, and efficient well operations by utilizing
real-time information. The bp Well Advisor integrated consoles were
introduced in the Caspian in 2012 when the casing running console
became fully operational on all three Azeri platforms and further
on the deepwater Guneshli,” the paper recalls.
According to bp, it takes the cake in the so-called 4D seismic
survey.
“We launched a new 4D seismic survey program of the reservoir
floor in the ACG field in January 2024. This is bp’s largest-ever
commitment to a global seismic survey in all its aspects – area
size, cost, and program duration. The new program, which focuses on
the Balakhani and Fasil ACG reservoirs, covers an area of 740
square kilometers beneath the hydrocarbon source. The program is
valued at $370 million and has a duration of five years
(2024-2028). The state-of-the-art 4D technology used for this
program will allow us to obtain more detailed data about the
reservoir, helping us to achieve maximization of field resource
recovery in the coming decades,” the publication notes.
Furthermore, the company views Azerbaijan as a hotbed of
technological know-how in well completion, which then gets the ball
rolling for operations in other regions of bp’s endeavors.
“Today at ACG, the standard completion design for producing
wells is open-hole gravel packing (OHGP). This was a real
breakthrough in the early 2000s, and we still believe it is
effective,” the publication reads on.
The company also reported effective distributed temperature
sensing (DTS) technology via fiber optic cable (since 2004).
“Moreover, in 2023, bp successfully installed the industry’s
first “Dual Clad” fiber-optic cable in the ACG fields, enabling
simultaneous acquisition and monitoring of DTS and distributed
acoustic sensing (DAS) data. This work has resulted in safer and
more efficient well operations, integrity, and potentially improved
seismic data quality,” bp says.
The company also cited downhole seismic as an important
experience at ACG.
“The world’s first “Downhole Flow Control Valve” (DHFC), a
subsea water injector equipped with expandable sand filters and a
downhole flow control valve, was utilized at Guneshli in 2008. The
world’s first three-zone DHFC-equipped DTS water injector was
commissioned in 2018 at ACG – a revolutionary technology to
properly manage multi-layered reservoirs. This has opened up
opportunities for further applications in other bp regions,” the
information on bp noted.
The company also counted the bp Slug Controller, bp Drawdown
Controller, Pipeline Inspection Device (PIG), monitoring system
using remotely operated vehicles, and Autonomous Underwater
Vehicles (AUVs) among the most important technological solutions
thanks to ACG.
A recent achievement is that the production platform “ACE” (from
which the first oil was obtained in April 2024, is part of ACG) has
the concept of remote control (from Sangachal Terminal).
As a result, the ACE operations have put bp in the driver’s seat
to cultivate future technologies.
To note, bp has been operating in Azerbaijan for 32 years, and
its total investments together with its partners in ACG over the 30
years of the ACG project amounted to $45 billion.
