Unlocking the potential

The countries of the region are keen to unlock the potential of their unconventional oil and gas resources. Saudi Arabia is home to the Jafurah gas field, the largest liquid-rich shale gas play in the Middle East, estimated to contain more than 200 trillion scf of gas and 75bn bbl of condensates. The field is currently being developed, with initial production expected to commence in 2025 and plans to ramp up to reach a sustainable sales gas rate of two billion scfd by 2030, in addition to significant volumes of ethane, Natural Gas Liquids (NGL) and condensate.

While Abu Dhabi holds an estimated 220 bbl of unconventional oil and 460 Tcf of unconventional gas in place. ADNOC is currently unlocking potential unconventional gas resources as part of its integrated gas strategy so that the UAE will become gas self-sufficient by 2030, with additional 1 billion cubic feet per day (bcfd) set to be unlocked from the Ruwais Diyab concession before 2030.

Sahil Kochhar, head of Presales, Miros outlines the benefits of smart, data-driven solutions for effective jack-up operations

For around 70 years, jack-up rigs have been at the forefront of offshore oil and gas exploration, acting as mainstays for drilling and production activities in most of the world’s hydrocarbon hotspots.

These mobile, self-elevating platforms provide stability in dynamic marine environments but, by their very nature, they are also often required to work in some of the most challenging environments known to the industry. They face significant challenges from waves and currents, which can drive structural integrity concerns and create potential safety issues.

The solution to this issue lies, as it so often does in offshore operations, in leveraging real-time environmental data. In the case of jack-ups, air gap measurements and wave/current monitoring are of particular criticality. By adopting cutting-edge solutions and technologies, operators can unlock new levels of performance, reduce risks, and optimise their offshore operations.

Understanding the air gap

The air gap refers to the vertical distance between the highest anticipated wave crest and the underside of a jack-up rig’s hull or deck.
Maintaining an adequate air gap is essential for structural integrity and operational safety. If compromised waves can slam into the structure, increasing stress on the platform and endangering personnel.

A well-calculated air gap, however, ensures stability, reducing downtime caused by rough sea conditions. It also avoids repeated wave impact, minimising the chances of fatigue, cracking, and deformation, extending the service life of the rig.

Real-time measurements

Real-time measurements capture key sea state parameters such as wave height, wave period, direction, current speed, and current direction. Up to the second data is gathered from various advanced sources - including wave buoys, radar systems, and subsea sensors – and used to inform decision-making, improve operations and enhance safety.

Actual conditions can often deviate from forecasts, but real-time readings of the sea-state removes the ambiguity, guaranteeing informed, timely decisions. Dynamic positioning and preload operations also benefit from wave and current insights, reducing risks of leg slip and seabed instability, while continuous monitoring highlights structural stress points early, allowing for pre-emptive action before maintenance issues escalate.

Enhanced jack-up operations through data-driven insights

The safety of people, the environment and assets are of the upmost importance during any offshore operation, be it with a jack-up rig or otherwise. With real-time wave data, operators can maintain safe clearance under the rig, preventing wave impact damage and guaranteeing structural integrity.

Continuous monitoring helps operators determine the best conditions for rig movement and positioning, improving efficiency, reducing costs and minimising the chances of an unexpected incident occurring.

Historical data also enhances future jack-up designs and operational procedures, fostering long-term resilience and reliability. Solutions like Miros’ RangeFinder and Wavex provide an integrated approach to monitoring critical environmental factors, serving as an example of how real-time measurements can contribute safer and more efficient jack-up operations.

How AI and predictive analytics are reshaping offshore operations

By combining RangeFinder’s precise air gap measurements with Wavex’s real-time wave data, operators get a holistic monitoring system for jack-up operations. With this powerful combination of live insights, operators gain a comprehensive view of their offshore environment, allowing them to make informed, data-driven decisions; reduce operational risks and enhance safety; and increase overall efficiency and reduce downtime.
As nearshore oil and gas reserves dry up and offshore exploration moves into deeper, more unpredictable waters, the role of real-time environmental data will become even more critical. Emerging technologies, like Miros’s PredictifAI – which pairs radar technology with Artificial Intelligence (AI) to predict waves and vessel motion – offer the potential to refine predictive analytics, allowing operators to anticipate and respond to changing sea states with unprecedented accuracy. By embracing these innovations, jack-up operators can drive greater safety, efficiency, and long-term profitability in their offshore ventures.
In an industry where precision and resilience are paramount, the future of jack-up operations depends on integrating smart, data-driven solutions that enhance situational awareness and enable proactive decision-making.
