Nakasawa ensures that its clients’ projects are successful, building a technical alliance that starts with project strategic design and continues through to its implementation, maintenance, and monitoring.
SERVICE AND SUPPORT IN EVERY STEP
Nakasawa provides full project implementation services, including the human resources and consumables needed to ensure successful enhanced oil recovery in new and mature heavy oil wells. In turn, clients can benefit from personnel trainings on the optimal use of SMH or SMC technology, ensuring they can handle the technology on their own and without any complications as their goals are achieved.
NAKASAWA'S COMPLETE SERVICE FOR IMPLEMENTING ITS STEAM INJECTION TECHNOLOGIES INCLUDES
- Reservoir analysis.
- Steam generator service and operation, including equipment and auxiliary services.
- Completion systems and equipment for injection wells.
- Completion systems and equipment for production wells.
- Monitoring of reservoir variables, optimization, and production.
Steam injection services must comply with all applicable national and international regulations at all times, and shall only be provided after taking the equipment manufacturers’ recommendations regarding installation, wiring, calibration, testing, special requirements, and others into account. This will ensure the equipment’s proper functioning and operation. Among the regulations that govern this service are:
- ISA (International Society of Automation)
- IEC (International Electrotechnical Commissions)
- ANSI (American National Standards Institute)
- A.P.I. (American Petroleum Institute)
- ASME (American Society of Mechanical Engineers)
- NEMA (National Electrical Manufacturers Association)
- NFPA (National Fire Protection Association)
- ASTM (ASTM International)
- ISO (International Organization for Standardization)
IMPROVED RECOVERY PROJECT MANAGEMENT
Nakasawa specializes in thermal processes, starting with a planning and consulting team that analyzes reservoir conditions, validates the exploitation plan, optimizes the opportunities portfolio, designs thermal completions, plans activities, and conducts scenario economic evaluations. After that, an experienced engineering and design team designs the portable or modular steam generation systems based on the client’s specific needs, always adhering to the highest quality standards. Finally, the company’s highly qualified operations team manages the client’s steam injection project during the operation and production phases.
AUTOMATION
As an integral part of the process, Nakasawa has incorporated operational parameter monitoring during the injection and post-injection stages to keep close control over all operations.
To guarantee optimum equipment performance and obtain high process efficiency, the company has incorporated the installation of cutting-edge technological sensors to measure downhole and surface parameters.
Sensors record data on parameters such as pressure and temperature, and fiber optics (DTS) and thermocouples verify the progressive state of the measurement system, system efficiency indicators, amplitude, and phase digits. In addition to documenting sensor performance over time, this setup also means potential problems can be detected in advance.
With process automation, it is possible to generate second-by-second pressure and temperature trend graphs. This speeds the decision-making process and helps optimize production in real time.
ONGOING MAINTENANCE SERVICES
At Nakasawa, we understand that to guarantee the success of any project, it is vitally important to work hand in hand with our clients to help them properly maintain the equipment that makes up this innovative system. All maintenance plans are governed by international standards and norms to help clients avoid, prevent, and reduce possible environmental impacts that can be generated during the execution of a project.
The high-quality steam system requires maintenance management to prepare, plan, and schedule activities to be carried out. This management is implemented in a cyclical, disciplined, and safe way from the time of its execution, always with a focus on continuous improvement. Through this, we can help ensure operational efficiency, availability, and reliability for all our clients.
