... The tool is adopted onto the Bottom Hole Assembly (BHA), as described by Husby et al. (2023) the Active Magnetic Ranging (AMR). The system includes a current transmitter, a magnetic receiver and a battery pack integrated in the BHA. This system can be operational when drilling, as long...

... Abstract In this paper, we introduce a cutting-edge solution to the complex challenge of managing operational costs in unconventional asset development, particularly concerning continuous well drilling, completion, and field maintenance operations within the oil and gas sector...

... avoidance gap in the PPR. This gap appears to be related to the formation being drilled and would change at the formation interface. In harder formations the requirement to stay above a threshold PPR to minimize reverse bit whirl is likely to conflict with the PPR for reducing HFTO. There is significant...

... that, the probability of wellbore collapse and an unrecoverable stuck pipe are discussed. The subsequent section provides an example of implementing the proposed decision approach. The final section presents the conclusion and future work. Methodology The cost saving of CTD compared to conventional drilling rigs...

... 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...

... 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...

... Accurate EMT performance prediction is important, especially at deeper drilling depth, and it can be achieved through numerical modeling ( Zeng et al. 2018 ). The purpose of this study is to investigate the signal dependence of factors such as depth of seabed, frequency of operation, azimuthal...

... 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 Tool (PLT) program was immediately...

... 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...

... It is important to note that well construction is a long process, and drilling itself takes 1/10 of the total time. The team noted that there is a need to improve efficiency both within each process and at the junction of related processes. Each major process consists of sub-processes and stages...

... 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...

... fluid GOR based on AMG data while drilling, before the wireline operation. This approach has clear advantages due to early access, low cost, and a continuous reservoir fluid GOR for all reservoir zones. In this paper, we release further study results to predict other fluid properties besides GOR, which...

...Introduction Abstract This paper will discuss the Managed Pressure Directional Drilling fit-for-purpose solution deployed to meet the drilling challenges faced in 5 consecutive wells drilled in South Texas, USA. This innovative solution integrates a state-of-art Rotary Steerable System (RSS...

... Abstract After findings were made in the pre-salt province that represented a major discovery for the oil industry, drilling activity in Brazil has been focused primarily on economically viable ways to develop these reserves. The pre-salt cluster is a geological formation that consists...

... 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...

In applying this workflow, managers will better understand both the drivers of uncertainty in expected value and how they can influence it via appraisal program design and setting commercial thresholds.
