Paper presented at the SPE Annual Technical Conference and Exhibition, September 23–25, 2024
Paper Number: SPE-220829-MS
... 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...

Paper Number: SPE-220976-MS
... 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...

Paper Number: SPE-215084-MS
... 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...

Paper Number: SPE-217479-STU
... 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...

... 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...

... ), 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...
