Paper presented at the SPE Annual Technical Conference and Exhibition, October 16–18, 2023
Paper Number: SPE-215005-MS
... 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...

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-215081-MS
... 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...

Paper presented at the SPE Annual Technical Conference and Exhibition, October 16–18, 2023
Paper Number: SPE-217479-STU
.... Real-time lithology 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...

Paper presented at the SPE Annual Technical Conference and Exhibition, September 21–23, 2021
Paper Number: SPE-205994-MS
... 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...

... 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...

Paper Number: SPE-195888-MS
... Preventing accidents is one of the most effective ways to reduce non-productive time while drilling, and consequently, reduce the cost of well construction. Existing drilling support software is used to control equipment loads and its operation, to control hydraulics, to increase drilling...

... development is to the point where we are drilling laterals of 1,500 m (~5,000 ft) or more. Although portions of the lateral may be of such poor-quality rock that we do not attempt a completion, there will be portions where we do. Ideally with geosteering this will be 90 + % of the lateral. Further...

Paper Number: SPE-196138-MS
... Improvement of the reliability of the seismogeological model forecasts is required to minimize project risks. Taking into account the block structure of the fields, drilling of multiple exploration wells and accounting of the 3D seismic survey data are the classic solution of this task in Eastern...

.... Exploitation of producing wells confirms the assumption of oil moving along the sub-vertical zones of destruction and contributing to the primary target Upper Jurrasic-1 reservoir. Drilling of sidetracks from low oil rate and high water saturation wells in the areas with increased fracture network identified...

... for the drilling engineer to make intelligent decisions and reduce the lost time for each stuck pipe event. Field datasets, including the drilling operation parameters, formation type, and fluid mud characteristics, were collected from 385 wells drilled in Southern Iraq from different fields. The new models were...
