Revolutionary strategies of exploration for oil and fuel, the growing use of cellular rigs, and the applying of recent applied sciences together with sensors and synthetic intelligence, have helped Adnoc Drilling to enhance ranges of effectivity, security and sustainability because it helps the expansion of Abu Dhabi’s vitality sector.
Drilling infrastructure is the spine of any oil firm. Upstream operators world wide depend on large buildings of metal and metallic to probe for, mine, and extract hydrocarbon assets buried deep beneath the earth’s floor. Abu Dhabi Nationwide Oil Firm, which began operations in 1971, has come a great distance. The state-owned oil firm is presently on monitor to increase its manufacturing capability to five million barrels per day by 2030.
Adnoc operates in a brand new world panorama, the place fossil fuels play a supportive function as international locations put together for an inevitable vitality transition. The UAE accounts for five.6 per cent of the world’s confirmed oil reserves and three.2 per cent of all fuel, in keeping with the BP Statistical Assessment of World Power 2021. Adnoc owns and operates a lot of the UAE’s oil and fuel concessions in collaboration with overseas companions.
The UAE, Opec’s third-largest producer has a number of the lowest price barrels of oil on the earth. Adnoc, which is making ready to diversify its vitality choices in step with the UAE’s deliberate commitments in direction of clear vitality, is more and more streamlining its drilling operations and producing environmental and value efficiencies.
Supporting Adnoc’s progress
A key driver for the corporate’s progress since 1972 has been its subsidiary, Adnoc Drilling, which operates the most important rig fleet within the area. Adnoc Drilling has an expansive fleet of 96 multipurpose onshore and offshore rigs. As Adnoc expanded its manufacturing capability, its rig fleet additionally grew to 96 right this moment from 29 in 2010.
In June, Adnoc Drilling drilled the longest effectively within the Center East at a depth of 43,000 ft
The corporate operates round 10,000 wells, which stretch throughout an space of 19,960 sq. kilometres up to now, to assist oil and fuel manufacturing onshore and offshore the UAE. The UAE’s oil manufacturing averaged 3.6 million bpd in 2020, in keeping with the BP Statistical Assessment of World Power 2021. Manufacturing of fuel, a gas the UAE makes use of largely to generate electrical energy has additionally surged.
Adnoc is trying to faucet newly-discovered reserves of fuel and attain self-sufficiency within the gas. Manufacturing of fuel within the UAE reached 55.4 billion cubic metres final 12 months. As the corporate appears to be like to extend the capability to supply crude in addition to fuel, it’s using new strategies of drilling to attain effectivity. Utilizing enhanced and built-in operations, Adnoc Drilling lowered the time wanted to maneuver rigs between numerous operations by 25 per cent between 2017 and 2019.
A lot of the effectivity has been generated by adopting horizontal and directional drilling to assist drill extra effectively and in addition decrease environmental footprint. In June, Adnoc Drilling drilled the longest such effectively within the Center East at a depth of 43,000 ft. Drilling horizontally, the corporate can goal and entry tender layers of rock with larger effectivity and in addition generate higher price advantages in comparison with a standard effectively. The common vertical technique of drilling as compared causes larger logistical points and ends in much less oil extraction.
Revolutionary drilling methods
With horizontal drilling, the corporate can produce as much as 3 times extra oil and entry a wider span of the reservoir as compared with typical strategies.
We began drilling these [extended reach] wells – at the start it was very troublesome as a result of it took greater than 100 to 130 days and now we have accomplished the longest effectively by 66 days
Hamad Al Junaibi, Adnoc Drilling
“The conventional typical manner, of drilling with a platform by a jacket rig was taking from 60 to 80 days. And we began drilling these [extended reach] wells – at the start it was very troublesome as a result of it took greater than 100 to 130 days and now we have accomplished the longest effectively by 66 days,” says Hamad Al Junaibi, senior vp of operations – offshore at Adnoc Drilling.
The prolonged attain wells assist the corporate keep away from drilling in areas with vital environmental and ecological worth. It permits the operator to drill beneath the realm reasonably than drilling instantly inside these delicate areas. Strolling rigs, which transfer between property with out requiring extra infrastructure construct are additionally a well-liked approach to elevate effectivity and decrease prices. The corporate started using such gear manufactured by the Chinese language Honghua Group from 2013 onwards.
The Asian firm has manufactured 9 of the rigs which “stroll” throughout gear with two land rigs additionally deployed on synthetic islands, the place Adnoc drills for hydrocarbons. Adnoc has invested in vital technology of native manufacturing worth by means of its drilling actions. The corporate has invested greater than Dh7bn by constructing 9 jack-up and eight land rigs within the UAE. The jack-up rigs had been constructed within the northern emirate of Sharjah by Lamprell and entered Adnoc’s service in 2011.
Adnoc has managed to avoid wasting practically $1 billion between 2016 and 2019 by producing 30 per cent discount in effectively length. The corporate’s use of superior expertise, similar to integrity sensors has additionally helped generate a 30 per cent discount on logging time over the past two years. Adnoc Drilling additionally helped save $20 million by reducing effectively supply time by shaving off 422 days of operation.
Presently, Adnoc is continuing with vital work in drilling actions as it really works to boost manufacturing capability. In July, Adnoc awarded $763.7m (Dh2.8bn) price of contracts to increase manufacturing from its offshore Higher Zakum and Satah Al Razboot (Sarb) fields because it goals to boost manufacturing capability to five million barrels per day by 2030.
The corporate awarded the contracts for built-in rig-less providers throughout six of its synthetic islands to Schlumberger, Adnoc Drilling and Halliburton. Whereas drilling for oil and fuel offshore, the corporate makes use of synthetic islands to assist with the manufacturing of oil and fuel offshore as they assist decrease prices and cut back environmental impression. It additionally permits the corporate to utilise lower-cost drilling rigs used on land as an alternative of the costlier offshore jack-up rigs.
Adnoc plans to develop its typical drilling exercise by 40 per cent by 2025 and considerably ramp up the variety of its unconventional wells as a part of its plans to extend capability.
An emphasis on security
Parallel to the expansion in manufacturing throughout numerous property, Adnoc can be navigating a worldwide setting of elevated scrutiny on the integrity and security of oil and fuel gear. The current explosion of an underwater pipeline operated by Pemex off the Gulf of Mexico has renewed considerations concerning the long-term security of oil and fuel infrastructure and the business’s impression on the setting.
“Normally, we take excellent care of asset integrity. It prices us a bit, however we’re placing the asset integrity and security in actual precedence. After I do my operations assembly each Sunday, I often I spend greater than 50 per cent [of the time] in HSE [health safety and environment] in addition to asset integrity,” Mr Al Junaibi says.
The corporate can be more and more adopting synthetic intelligence in effectively upkeep. The expertise helps to foretell drill failure as much as two hours forward, thus considerably decreasing potential lack of manufacturing time. Aside from guaranteeing security, Adnoc can be striving to be sure that its upstream sector, which is historically probably the most carbon-emitting facet of the oil and fuel enterprise, more and more falls in step with its sustainability objectives.
Adnoc is trying to decrease its greenhouse fuel emissions depth by 25 per cent over the subsequent ten years
Adnoc is trying to decrease its greenhouse fuel emissions depth by 25 per cent over the subsequent ten years. The corporate’s plans to decrease its carbon footprint can be more and more factored into its drilling subsidiary’s work, notably in well being, security and setting.
Its HSE coverage “states clearly that we care about individuals, we have now to be sure that no hurt to individuals no hurt to the setting and to preserve vitality,” says Muneef Ibrahim Mohamed Salem, supervisor, HSE at Adnoc Drilling. “So as to attain that time, to cut back the greenhouse gases emitted to the setting, we managed to get these new engines on rigs to generate energy with the most effective expertise obtainable in the marketplace,” he added.
The engines utilized by Adnoc use much less gas, and due to this fact emit comparably much less greenhouse gases into the setting.
“We managed to cut back the CO2 emissions of round 130,000 tonnes over the past 5 years, attributable to these new engines that we have been utilizing, which is equal to round 30,000 automobiles a 12 months,” says Mr Salem.
