This is one of my early works in the oil&gas industry more than a decade ago. https://lnkd.in/eaiSMtbp The LWD (Logging-While-Drilling) has the advantage of being capable of measuring the borehole physical properties (e.g. formation slowness) while drilling a wellbore. This LWD technology reduces the time&cost compared with the conventional Wireline measurement which deploys a measurement tool after the drilling which requires additional cost & time. The technology of LWD measurement was getting popular at that time and was getting more attention, but its technology was quite yet unmatured. This is partly because, as its name of the LWD suggests, the measurement of the formation slowness while drilling was extremely challenging (quite noisy because of a drilling noise, and banging noise etc). Accordingly, previously this work, the measurement of the shear slowness in the LWD condition was quite limited. In this work, for the first time in the oil&gas industry, a new technology was introduced to enable a robust slow shear measurement under the LWD condition. More importantly, not only this new technology gives a measurement robustness, it also allowed to extend the measurement range, meaning that it was a key enabler for a new formation measurement that could not be explored/assessed in this LWD technology (it was possible only in the Wireline measurement tools). I contributed, as a geophysicist/algorithm developer, to this work to establish an entire data processing workflow to solve an inverse problem* and its algorithm quality evaluation. At that time, the term of the Artificial Intelligence (AI) was not popular yet (no deep learning, but support vector machine in the machine learning was popular), but this kind of technical activity was more than AI, in the sense that everything should be white-box (i.e. explainable) with a rigorous validation process, including a failure and success of the measurement/processing. Now we have an AI in a various industry/daily use, and it is not difficult to develop/apply the AI if we don't need to take the quality/explainability into account or a research (it is inherently a black-box type of approach). But when it comes to the aplication to any mission-critical use cases, it is still quite a challenge. In this sense, I would say that AI is getting popular, but still its robustness/applicability is somewhat challenging as we previously faced with for the early LWD technology. In my next career endeavor, I will work for the AI. It will be my pleasure if I can dedicate myself to such AI challenges for various business scenes. *inverse problem: One field of mathematics/optimization problem. In this context, to extract a formation shear slowness from pressure sensor data based on a physics model in the wellbore.

AI Well Planner now has the capability to design an entire well pad. You input the surface coordinates, target points, kick-off point, DLS and inclination constraints for the TVD intervals, ESP requirements, as well as anti-collision rules. Then, you run the calculation, wait, and evaluate the results. Additionally, AI Well Planner can do the same, but with cost optimization for well construction. To do this, you need to specify the Wellbore Geometry and the cost of various components such as casing, cement, drilling mud, drilling time, etc. And the cherry on top is the target vs wellhead sorting algorithm. The optimal matching of targets to wellheads significantly simplifies collision avoidance, makes drilling safer, and life easier 😀 Find out more at https://mwdstd.com/ #ai #ml #machinelearning #drilling #drillingengineering

AI Well Planner took 3 minutes to design a trajectory that saved over $700,000 while accounting for torque-and-drag for casing running, kick-off point, and DLS constraints. You probably wouldn't have had time to make a coffee... We analyzed well construction costs affected by the trajectory, and selected the following factors: drilling cost per meter, drilling time, drilling fluid, casing, cement slurry, and cuttings disposal. We also considered that not every geometrically precise trajectory is suitable for running casing - AI Well Planner now takes into account torque-and-drag during the casing running process. Redesigning the transport section from the previous post saved $745,000 compared to a design by human. The snapshot load graph also shows that the casing of the third section is at the limit of helical buckling. This is an extreme case, demonstrating AI Well Planner's ability to find the most optimal solution. In reality, a safety factor of 0.7-0.8 will be used for helical buckling. #ai #ml #machinelearning #drilling #drillingengineering #oilandgas

STUCK PIPE INCIDENT. A stuck pipe incident occurs in drilling operations when the drillstring becomes immobilized or difficult to move further down the wellbore. This can happen due to various reasons, including differential sticking, mechanical obstructions, wellbore instability, or equipment failure. When a pipe becomes stuck, it can result in costly downtime, compromised wellbore integrity, and potential safety hazards. Artificial intelligence (AI) can play a significant role in mitigating and addressing stuck pipe incidents by leveraging advanced data analytics, predictive modeling, and real-time decision support. Here's how AI can treat this issue: -Early Detection: AI algorithms can continuously analyze drilling parameters, surface data, and downhole measurements to detect early signs of a potential stuck pipe incident. By identifying deviations from expected trends or anomalies in data patterns, AI systems can alert drilling personnel to take preventive action before the situation escalates. -Root Cause Analysis: AI-powered diagnostic tools can conduct root cause analysis to determine the underlying factors contributing to a stuck pipe incident. By analyzing historical data, geological formations, drilling practices, and equipment performance, AI can identify the primary causes and help operators understand why the incident occurred. -Decision Support: AI platforms can provide real-time decision support to drilling engineers and rig crews when addressing a stuck pipe situation. By analyzing vast amounts of data and considering various factors such as formation properties, drilling parameters, and operational constraints, AI systems can recommend optimal courses of action to free the stuck pipe safely and efficiently. -Predictive Maintenance: AI-based predictive maintenance models can anticipate potential equipment failures or malfunctions that may lead to a stuck pipe incident. By monitoring equipment health, vibration patterns, and performance metrics in real time, AI systems can identify early warning signs of impending issues and enable proactive maintenance interventions to prevent downtime. -Dynamic Wellbore Modeling: AI-powered wellbore modeling software can simulate different scenarios and predict the behavior of the wellbore under various conditions. By incorporating geomechanical data, fluid dynamics, and drilling parameters, AI models can optimize drilling strategies and mitigate the risk of wellbore instability or formation damage that could contribute to a stuck pipe incident. -Continuous Learning and Improvement: AI systems can continuously learn from past stuck pipe incidents and their outcomes to improve their predictive capabilities and decision-making algorithms. By analyzing historical data and performance feedback. A relevant video below. Contact :[email protected] #AI #drilling #virtualassistant #stuckpipe #incident #enginereering

While you're discussing over lunch why the markets and oil prices have dropped, AI Well Planner can design an entire well pad for you, accounting for anti-collision, torque-and-drag for casing running, kick-off point, and DLS constraints. So, you'll still have time to figure out where the markets will end up... And yes, the well pad can be redesigned every time a finely planned trajectory clashes with the harsh realities of directional drilling. Perhaps... Although all of this might become irrelevant if the oil price drops below $30 per barrel. What do you think? #ai #ml #machinelearning #drilling #drillingengineering #oilandgas

As we know a stool needs three legs to stand - at #AIQ we deliver revolutionary #ai #solutions with three key ingredients: #datascientists #swengineers and #SMEs …..supported by volumes of #data
Multimodal AI for Drilling Optimization ⚙️⛓️🤖👁️🧠 Imagine a world where every detail of drilling operations is captured, every vibration, every sound, and every visual cue from the rig is transformed into actionable intelligence, paving the way for unprecedented operational optimization and risk management. Drilling activity detection not just through traditional sensor data 📈📉, but via a symphony of multimodal inputs: high-resolution camera streams 📹, precise time-series sensor data, the subtle nuances captured by microphones 🔊, and even subsurface data. This is the patent we just filled with the AIQ team. This patent represents more than just an advancement in technology — it’s a leap towards a safer, more efficient, and profoundly insightful drilling process. 🎥 To give you a glimpse of our solution, I’ve created a video showcasing the vision based drilling activity detection, where I applied AI on the « 2 newbie roughneck make it easy » popular video — keep your sound on! 🔊 I’ve created models that can detect and track movements of equipments (drill pipes, tongs, slips) and then detect operations / drilling activities, where each operation duration is automatically counted. Imagine the power of insights we can get out of such a solution deployed along with other modalities, on a fleet of drilling rigs. But as mentioned, vision can be occluded, low resolution, sensors data can be corrupted or just not informative, sound can be noisy, subsurface data can be too low level, that is why having a multimodal approach is the best way towards reliable and robust drilling activity detection solution. And as we always say « you can only improve what you can measure with precision »… the higher the accuracy of analytics, the better the actionable insights and therefore the better the optimization. —— A heartfelt shoutout to the dream team behind this - my data science drilling team at AIQ, Amine E., Abdallah Zakaria B., and Sebastiaan Buiting, for pioneering the AIQ's OPTIDRILL sensor-based AI solution and expanding it towards multimodalities through this patent. Big shout out also to all co-inventors from #AIQ (Imane Chraibi, Arghad Arnaout, this could not be possible without you guys!), #ADNOC_Technology (Ridha Zegdane, special thanks for all initial work!) and all other colleagues from #ADNOC_Onshore, #ADNOC_Offshore & #ADNOC_Drilling. #drillingoptimization #multimodalAI #patent #efficiency #ADNOC

What is synthetic seismic modeling used for? Being president of Tesseral Ai and supporting our products I need to explain this. BTW, there are many in Tesseral Ai who support and help me with some of this.
Seismic synthetic modeling is often inquired about regarding its utility: Seismic modeling is not limited to seismic acquisition; it plays a vital role throughout the seismic lifecycle, offering insights into the characteristics of the seismic data recorded. In the phase of seismic acquisition, modeling assesses different acquisition geometries and subsurface model hypotheses to identify the optimal acquisition strategy for imaging the subsurface. In seismic processing and imaging, modeling is essential for noise reduction, multiple suppression, migration, and inversion. It plays a key role in the ultimate interpretation of seismic images, aiding in the verification of significant features and the estimation of lithology or fluid content. Additionally, the generation of synthetic data sets for research has greatly aided the seismic exploration community, providing a standard and a platform for testing new processing algorithms. Looking to the future, one expected use of modeling is to train supervised machine learning algorithms (as illustrated in the figure below).

𝗦𝗲𝗶𝘀𝗺𝗶𝗰 𝗗𝗮𝘁𝗮 𝗙𝗶𝗹𝘁𝗲𝗿𝗶𝗻𝗴 𝗧𝗲𝗰𝗵𝗻𝗶𝗾𝘂𝗲𝘀 1. **Bandpass Filtering:** Bandpass filtering selectively removes frequency components outside a specified range while retaining frequencies of interest. This technique is commonly used to suppress low-frequency noise (such as ground roll) and high-frequency noise (such as air blasts) while preserving seismic reflections. 2. **Denoising Algorithms:** Denoising algorithms, including median filtering, wavelet denoising, and empirical mode decomposition, aim to attenuate random and coherent noise present in seismic data. These algorithms exploit the statistical properties of noise and signal to enhance signal-to-noise ratio (SNR) and improve data quality. 3. **Spectral Whitening:** Spectral whitening techniques aim to flatten the seismic spectrum by equalizing the amplitude of frequency components across the seismic bandwidth. This approach enhances the resolution of seismic data and improves the interpretation of subtle geological features. 4. **Deconvolution:** Deconvolution techniques, such as predictive deconvolution and wavelet deconvolution, aim to enhance seismic resolution by compensating for the effects of the seismic wavelet and source signature. Deconvolution removes reverberations and enhances the definition of reflectors, particularly in complex geological settings. 5. **Adaptive Filtering:** Adaptive filtering algorithms, such as the least-mean-squares (LMS) algorithm and the recursive least squares (RLS) algorithm, adaptively adjust filter coefficients based on the local characteristics of the seismic data. Adaptive filtering is particularly effective for attenuating coherent noise and enhancing signal fidelity. ### Significance in Subsurface Imaging: 1. **Improved Interpretation:** Filtered seismic data provide clearer and more coherent images of subsurface structures, facilitating accurate interpretation of geological features, stratigraphy, and fault systems. 2. **Enhanced Reservoir Characterization:** By suppressing noise and enhancing signal resolution, filtering techniques enable geoscientists to delineate reservoir boundaries, identify fluid contacts, and estimate reservoir properties with greater confidence. 3. **Reduction of Imaging Artifacts:** Filtering techniques mitigate common imaging artifacts, such as multiples, ground roll, and acquisition footprint, which can obscure seismic reflections and complicate interpretation efforts.
