SPM Side Pocket Mandrels for Oil & Gas Production Strings
Innovative Design of SPM Side Pocket Mandrels
The oil and gas production process goes through a complex network where increasing efficiency and productivity is the most significant goal. Dozens of different downhole tools and equipment are used to reach these targets, each being dedicated to a different function and purpose, or to fulfil a specific purpose that improves the performance of the operation. These intervention tools include, but are not limited to, Side Pocket Mandrels (SPMs) that are significant parts of production strings applied for well intervention, monitoring, and control. In this article, we explore how SPM works, why it is used, and some of the functions it serves in an oil and gas system.
What Are Side Pocket Mandrels (SPMs)
SPMs or Side Pocket Mandrels are special downhole tools that are made to be installed in the production strings that are placed over a length of tubing or casing at regular intervals. These mandrels also have side pockets or receptacles capable of housing several types of downhole devices, including safety valves, chemical injection tools, gas lift valves, or downhole gauges.
SPMs allow the ability to deploy & retrieve these tools without the expensive workover operations, providing operational flexibility and efficiency. They are accepted as the heroes who enable intelligent well intervention strategies that increase well performance, minimize downtime, and reduce costs.
Introduction to SPMs and Their Functions
1. Tool Deployment and Retrieval
✔The main application of SPMs are to offer housing and support for downhole tools and equipment utilized in oil and gas production activities.
✔SPMs eliminate the need for a full-scale intervention or tubing retrieval by integrating side pockets or receptacles into the mandrel design (allowing for installation, retrieval, and replacement of downhole devices).
✔By doing so, this feature minimize the operational downtime and helps in increasing well performance, thus correlating it to the modern production systems.
2. Monitoring and intervention in the well
✔SPMs Support Well-Intervention Activities. SPMs enable deployment of complete downhole tools and instruments including logging, pressure control, workover, and other monitor-related activities.
✔SPMs help with integrating everything from safety valves and chemical injection systems to downhole gauges and flow control devices into the production string.
✔This functionality is a great value-add for well management, balancing reservoir efficiency with reduced intervention costs.
3. Production Optimization
✔They are a vital component of gas lift valves deployment, chemical injections and flow control devices, tools that are the ones that maximize production efficiency in SPM.
✔By strategically placing them at pre-designated points along the production string, operators can design production strategies that maximize reservoir recovery and optimize production rates.
SPM Applications on Production Strings
1. Gas Lift Optimization
✔Gas lift valves, used for artificial lift operations to improve production rates in gas lift wells, are often housed within SPMs.
✔Using gas lift valves at different depths in the production string allows operators to change the lifting gas injection rates to keep the bottom hole pressure in the target range.
✔It helps to deliver optimum production effectiveness and thereby decreases operational costs for lifting fluids.
2. Chemical Injection
✔SPMs are housing or compartments for **chemical injection tools needed to inject corrosion or scale inhibitors or de-emulsifiers into the wellbore.
✔These chemicals address production problems, including corrosion, scale, and emulsion collapsing.
✔Prolonging Equipment Lifespan: Operators can address wellbore issues and prevent degradation by injecting chemical solutions through SPM integrated with their production strings.
3. Downhole Monitoring
These monitoring tools gather real-time data about reservoir dynamics, fluid characteristics, and wellbore conditions.
✔With real-time reservoir monitoring, operators can take informed decisions to maximize hydrocarbon recovery and keep production efficiency high.
