... is not well understood. Therefore, numerical models have been developed to simulate the detailed dynamic responses of gun systems subjected to multiple shaped-charge detonations. This paper describes the coupling of hydrocode-based three-dimensional (3D) numerical models with FEA and full- scale surface...

... applicable within a narrow set of well conditions. Recently, the industry practice has been to use mathematical simulation to estimate downhole temperature when well conditions fall outside the parameters given in this set of recommendations. Accurate temperature estimates provide the best test parameters...

... Abstract Three-dimensional (3D) finite element analysis (FEA)-based shock software is the next step in downhole shock modeling. This software uses a finite element and a fluid tool that simulates gun behavior on gun strings and adjoining tools, including perforation and subsequent stress...

... solution to mitigate APB and protect casing strings in offshore HP/HT wells. This paper focuses on the modeling and simulation of the effects of syntactic foam deformation on APB in casing/tubing annuli. Syntactic foam is a composite material synthesized by filling a polymer, metal, or ceramic matrix...

This paper presents results that illustrate the capacity of this new system to mitigate losses and improve mechanical properties of the formations. Abstract Drilling in deepwater environments poses many challenges...

...Simulators in the Oil and Gas Industry Drilling simulators can be categorized into training and engineering simulators which could be both implemented entirely in software, hardware or a combination. Millheim (1986) has categorized training simulators further as partial-task, procedural...

... in deepwater cementing, it has many potential benefits compared to the conventional placement. Simulation of reverse placement is not possible with existing commercial software. Therefore, jobs were designed using specialized prototype software that enabled the design engineer to accurately reconstruct field...
