The alignment pins having a fork connector that is connected to a knife connector. When the skid sections are connected, the piping, electrical, and pneumatic tubing connectors are connectable to the other corresponding skid piping, electrical, and pneumatic tubing connectors without the need for welding or field construction of connecting components. The modular skid oil production system is capable of expansion or contraction as required by the operation of the system. For example the system includes removing a skid section having a larger separator and replacing it with a skid section having a smaller separator, without the need of welding or field construction of connecting components.

[0058] As discussed above, over time a well's oil production can decrease by fifty percent (50%), which results in equipment, such as separators that were originally installed with the inception of the well, now being oversized. However, replacing the equipment with smaller, less expensive in both initial and operating costs would require the production well to be shutdown and the system purged in order to perform the requisite welding and running of the various electrical, piping and pneumatic connections. In some cases the production capabilities of a well may have been underestimated and therefore results in the installed equipment being undersized. Embodiments of the present invention resolve these issues and allow for the contraction or expansion of oil production systems using skid mounted components, without the need for welding onsite.

[0061] In a further aspect of an embodiment, overtime, the production of well 2 begins to decrease, such that the large separator 160, that likely had been used since well 2's commissioning is now oversized. The operator can remove separator 160 from being associated with well 2, and a smaller separator 150 can replace larger separator 160 as shown in
[0062] As shown in
[0063] An example of the removal and replacement of modular skid systems while the oil production processing system is in operation is now described. Referring to
[0064] To replace the larger separator 160 with smaller separator 150, after larger separator 160 has been removed, place smaller separator 150 in close proximity to pipe rack 200 skid. Using the alignment guide plates of fork 210, pin 215, and knife 220, push separator 150 into position at pipe rack 200 skid until knife 220 and fork 210 alignment plates and pin 215 engagement occurs. Connect tubing connections 230 (see

Data Analytics and Neural Networks
[0075] In a further aspect of an embodiment, the system includes a control system, such as a DCS, PLC, SCADA, or wireless control system (e.g., wireless instrumentation and control devices that communicate over a wireless network), or a combination of these types of control systems that are operatively in communication with the modular production system's instrumentation, actuators and valves. The control system can be used to monitor and control the operation of the production system. Additionally, the system can be controlled and monitored remotely, and production system data for one or a multitude of production systems is collected, analyzed, and used for benchmarking purposes, as well as optimization and predicting operation of production systems, including separators, to generate and predict production systems operational setpoints, maintenance needs, measurements, and values, including service to the equipment, such as the need to drain sand from the integrated sand separator. Additionally, the need to replace an oversized, or in some cases undersized separator, can also be determined using these systems. For example, and as shown in

[0077] The middle layers, sometimes referred to as the hidden layers, which include neural processor layers h11 through h14 and h21 through h24, are activated through weighted connections and receive activation data from previous neural processors. For the sake of simplicity, two middle layers are shown although these layers can be multiples of what is shown and the number of layers depends upon the input and how “deep” of an accumulative learning process is required to obtain a reliable result. Some of the neural processors in the middle layers will influence the output by triggering events based upon one or more other events occurring in the middle layer or directly from input data. Depending upon the accuracy and comprehensiveness of the input data, the problem to be solved and how the neural processors are connected, obtaining an output z1 and z2, in order to, for example, predict timing of the need to drain the sand from the high pressure separator.
