... to create a safe workplace, not all industries face the same HSE risks. The risk profile of the oil and gas industry, specifically the drilling sector, is inherently much greater than many other industries. Drivers of this elevated risk profile include unique challenges such as the everchanging pace...

... Abstract The demands of the oil and gas industry are placing an increased importance on drilling harder, faster, and longer, giving rise to the challenge of premature bit failure due to drilling through transitions of varying rock strength. To address this, new strategies have become more...

... During the later part of an oil or gas field's production, it is common to drill new well sections in between old and often abandoned wells, so-called in-fill drilling. To avoid colliding with existing wells or abandoned wells is a vital scope of these infill drilling operations. To be able...

... asset development, particularly concerning continuous well drilling, completion, and field maintenance operations within the oil and gas sector. These complicated field operations involve hundreds of service providers and incur vast volumes of invoices every year. Tremendous values are lost due...

... decision-making efficiency. As energy demand increases, oil and gas operators move into more challenging resources and drill highly inclined and extended-reach re-entries in depleted mature reservoirs to secure energy demand. In mature fields, substantial hydrocarbons are often left behind due...

... Abstract Accurate determination of formation tops while drilling is a critical part of exploration geology workflow. Operational decisions on coring, wireline logging, casing and final well depth largely depend on it. One of the commonly used methods for picking formation tops while drilling...

... determination while drilling can greatly optimise the drilling process and enhance geosteering. Using linear, non-linear, and ensemble machine learning algorithms, this study sought to automate the process of lithology classification while drilling. Also, the project sought to create a web application...

... included drilling a 3-kilometer-deep exploration well to collect subsurface data from the deep sedimentary and crystalline basement rock formations. These data will inform the design and specifications for creating an "enhanced geothermal system" comprised of a network of open fractures that will serve...

... Abstract Electromagnetic telemetry (EMT) system uses a downhole source inserted near the drilling bit to send out real-time measurements via low frequency electromagnetic waves. A surface antenna picks up the transmitted signal by measuring the potential difference of two locations. Compared...

... Abstract Logging-While-Drilling (LWD) formation testers have been successfully used for years in measuring formation pressure and estimating formation mobility. In terms of applications, among many others, this data has been useful for mud weight optimization while drilling, reservoir fluid...

... and permeability within a three-way-dip closure against a large growth fault. In 2018, Shell T&T embarked on Dolphin Extension Campaign project of 4 infill wells to increase gas production to backfill to Atlantic LNG export and domestic market. Upon completion of the drilling campaign, a Production Logging...

... Abstract Drilling wells in the remote northeastern part of India has always been a tremendous challenge owing to the subsurface complexity. This paper highlights the case of an exploratory well drilled in this region primarily targeting the main hydrocarbon bearing formations. The lithology...

... Abstract Objectives/Scope The acquisition of mud gas data for well control and gathering of geological information is a common practice in oil and gas drilling. However, these data are scarcely used for reservoir evaluation as they are presumably considered as unreliable and non...

... by the digital twin improves efficiency and accelerates well construction process. Cognitive assistants based on AI and ML techniques are implemented at every stage: while planning, the assistants search analogue wells, analyze its design and complications while drilling and provide recommendations for the most...

... the dominant contributor of natural gas and condensates. The Vicksburg formation, over 8000ft thick (Hastings, 1985), is comprised of tight gas sands and shales, often times with hundreds of feet of accumulation. An integrated approach between MPD and Directional Drilling was identified to be an instrument...

... ), all PVT properties in unconventional reservoirs are strongly correlated with GOR. The next question is if we can use the same AMG data while drilling to predict other reservoir fluid properties besides GOR in conventional reservoirs. The reservoir fluid density is the most sought fluid property...

... Carbonate formations could be very challenging to drill especially when buried at some 5000 m depth as it is the case for the Brazilian pre-salt. Many factors contribute to a high variation in rock properties. Indeed, particles of carbonate rocks can be transported to the place of diagenesis...

...Introduction Since the original RTD analytics system [ Cao et al., 2017 , 2018 ] was deployed to production, it has become a powerful decision support tool for the drilling operations team; however, it has not been without many challenges. Such challenges include: latency and data...

... and also thereservoirproperties of the rock themselves. As unconventional resource plays took off, many North American Basins have been carpeted with high quality 3D seismic that is routinely be exploited to reduce drilling risks, improve completion efficiency and high-grade acreage based on seismic...

... Abstract Majority of the accidents while drilling have a number of premonitory symptoms notable during continuous drilling support. Experts can usually recognize such symptoms, however, we are not aware of any system that can do this job automatically. We have developed a Machine learning...
