摘要： A method may include obtaining (300; 305) first nuclear magnetic resonance (NMR) data (421; 422) and acquired permeability data (460) regarding a geological region of interest. The method may further include determining (310), using a neural network (590) and second NMR data (421; 422), predicted permeability data (470) regarding a predetermined formation within the geological region of interest. The neural network (590) may be trained using the first NMR data (421; 422) and the acquired permeability data (460). The method may further include determining (320) a predetermined fracture size within the predetermined formation based on the predicted permeability data. The method may further include determining (330) a predetermined type of lost circulation material (LCM) based on the predetermined fracture size. The method may further include transmitting (340) a command to a well system (110; 112; 114) that triggers a well operation using the predetermined type of LCM.

摘要： A closed-loop drilling fluid condition system for drilling fluid mixing and recycling process is described. The closed-loop drilling fluid condition system improves drilling fluid quality, repeatability, utilization efficiency, and health, safety and environment (HSE) issues. In particular, the closed-loop drilling fluid condition system automates a water-based drilling fluid workflow or an oil-based drilling fluid workflow where individual stages are monitored and adjusted in real-time. Specifically, the individual stages are monitored in real-time using sensors and adjusted in real-time based on commands from a monitoring device to achieve specific drilling fluid parameters.

摘要： A method may include obtaining, in real-time, well data (113) regarding a wellbore and drilling fluid data (111) regarding drilling fluid circulating in the wellbore. The method may further include determining, based on the drilling fluid data (111), a plastic viscosity, or PV, value and a yield point, or YP, value regarding the drilling fluid. The method may further include determining, based on the well data and the drilling fluid data (111), an equivalent circulating density, or ECD, value of an annulus of the wellbore. The method may further include determining a hole cleaning efficiency, or HCE, value based on a hole cleaning model, the PV value, the YP value, and the ECD value. The method may further include determining an adjusted rate of penetration, or ROP, value for a drilling operation in the wellbore based on the HCE value and a current ROP value. The method may further include transmitting a command to a drilling system (120) that produces the adjusted ROP value in the drilling operation.

摘要： A method may include supplying water for a mud mixture to a mixing tank (151-153) according to a predetermined volume. Tire method may further include supplying, using a rheological sensor, a viscosifier to the mud mixture (154-156) in the mixing tank (151 -153) until the mud mixture (154-156) achieves one or more predetermined rheological values. The method may further include supplying, using a density sensor, a weighting agent to the mud mixture in the mixing tank (151-153) until the mud mixture (154-156) achieves a predetermined specific gravity value. The method may further include supplying, using a pH sensor, a buffering agent to the mud mixture (154-156) in the mixing tank (151-153) until the mud mixture (151 -153) achieves a predetermined pH value to produce a drilling fluid.
