Definitions
- the cloud 6 can incorporate machine learning techniques to optimize the well production as a function of ran time of the pump subsystem 35, as well as establishing well performance optimization based on analysis of various pressure build up and flow-down rates and time frames seen at the control valve pressure transducer 28 and PDIEF, respectively.
- Certain wellbore construction and operating parameters can be input into the software architecture and the software will determine superficial gas velocities for all wellbore topologies present.
- the system 2 will estimate critical velocities for each discrete wellbore topology and will use this information as a baseline for determining the starting point for the shut-in state of the system 2, thus maximizing the in situ well energy and thereby increasing both the life and the expected ultimate reserves recovery of the well.
- the system 2 will monitor, record and leam from the nature of the pressure buildup: slope(s) of buildup, time to build to certain pressures, etc.
- the cloud 6 can be programmed to perform a Fast Fourier Transform on each buildup pressure and note the frequency domain and distribution of same, comparing each signature with various production and pressure buildup characteristics as an aid in determining when various production stages are contributing to wellbore fillage and production.
- the well 103 includes a conventional wellstring, which is similar to the wellstring 8 shown in Fig. 2. Multiple production wells 103 can be included in the system and driven by a single-point cloud/software system.
- the wellstring includes an outermost casing, an intermediate liner 12 and innermost, full-depth tubing 14.
- Such production wellstring components can be installed downhole as individual sections connected at their respective ends.
- Casings can be set-in-place downhole. Liners commonly terminate subsurface, and can be suspended from the casing by hangers.
- U.S. Patent No. 7,090,027 shows casing hanger assemblies, and is incorporated herein by reference.
- Treatment plans are commonly implemented with such chemical injection pumps and systems, which can inject anti-scaling, paraffin-eliminating and other control chemicals downhole.
- the local controller 104 would initiate operation of the chemical input subsystem 146 (e.g., pumps) to place chemicals in the backside (18 and/or 20) of the well 103 as it changes state from flowing backside production to gravity segregation in the pumping cycle.
- the chemical input subsystem 146 e.g., pumps

Abstract
L'invention concerne un système de commande pour un puits de production de pétrole et de gaz, lequel système comprend un dispositif de commande relié à un train de tiges de puits s'étendant en fond de trou à partir d'une tête de puits. Le système de commande maximise l'efficacité de pompage de fond de trou et la production de pétrole et de gaz par le contrôle et la commande interactifs de paramètres de fonctionnement de puits. Un procédé mettant en œuvre la présente invention optimise l'efficacité du fonctionnement et de la production de puits.
