Summary: Multiple ML and DL models were evaluated in classifying five wellbore fluid-loss classes from a drilling dataset in the Azadegan oil field, Iran. The tree-based and data matching ML algorithms outperformed DL and regression-based ML algorithms in predicting the fluid-loss classes. RF model provided the best predictions for fluid-loss classes 1 to 3, while ADA and DT outperformed RF for class 4 and class 5, suggesting an ensemble approach may be the best for reliable predictions.

Summary: Designing geothermal drilling fluids is complex due to high temperatures and corrosive environments. Lime shows the best thermal stability among alkalinity control materials, while Caustic Soda tends to gelate at high temperatures. Fine granular materials are less affected by high temperatures compared to flaky, fibrous, and coarse granular materials in terms of rheological behavior.

Summary: Lost circulation is a troublesome and expensive situation during drilling, especially in naturally fractured formations. Sealing fractures with granular lost circulation materials (LCMs) is a common method for lost circulation control. However, the effectiveness of this type of LCM is limited due to a poor understanding of how granular LCMs work. In this study, a coupled CFD-DEM model is used to simulate the sealing process of a typical granular LCM (calcium carbonate) in a wedge-shaped fracture. Comprehensive evaluation criteria for sealing performance are defined, and the effects of LCM, base fluid, and fracture geometry are investigated. The results provide insights into the working principle of LCMs and offer a scientific basis for LCM selection and design.

Summary: Serious drilling fluid loss problems occur in fractured reservoirs during drilling and completion. The indoor evaluation of drilling fluid lost control effect is fundamental for designing on-site plugging formulas, but there are issues with evaluating specific loss types. Therefore, this paper defines the main control factors for drilling fluid lost control efficiency based on the classification of loss causes and proposes a method for recognizing loss types. Laboratory experiments were conducted to evaluate the influence of fracture module and experimental steps on drilling fluid lost control efficiency. By analyzing indoor and field drilling fluid lost control efficiency, the best laboratory experimental conditions for different loss types were recommended, and an evaluation method considering various loss types was established. Through verification in the Tarim Basin, the test results closely matched the field lost control results, providing better evaluation of drilling fluid lost control efficiency to guide field leakage control assessment.

Summary: Modifying oil properties by heating it with inorganic or hybrid materials is a common practice in various fields, including painting. Ancient recipes mention the addition of metal compounds during heating to improve drying and rheological properties of oil binders, allowing pigments to be ground in such treated oils for use as paint. The process of forming a gel system using pigments and oil paint medium has similarities with formulating oil-based drilling fluids in the petroleum industry.

Summary: This study investigates the dynamics of bottom hole assembly for dual reaming and drilling operation, focusing on the stick-slip vibrations caused by the contact of the reamer and the bit with the formation. A coupled vibration model representing the drillstring is used to simulate the stick-slip vibrations caused by the dual-action of the reamer and the bit, showing elevated vibrations. Sensitivity analysis indicates that cutter aggressiveness for the bit and the reamer are key parameters affecting stick-slip behavior.

Summary: Predicting the rate of penetration (ROP) is crucial for optimizing drilling operations and reducing costs. Controllable parameters such as weight on bit (WOB), revolutions per minute, and flow rate (FR) have a significant impact on ROP. By optimizing these parameters, drilling performance can be improved leading to cost savings.
