Prevent Corrosion and Paraffin Deposition

In the past, preventing leaks and paraffin deposition in oil and gas gathering systems operated at low flow conditions would mean adding costs of repair or replacement of flowlines and losses of production resulted from unplanned well shut-ins. Now, Multiphase Advanced Pipeline System (MAPS) is able to provide next-generation corrosion prevention and flow assurance that can be achieved without human intervention.

​MAPS performs the following functions:

  • Flushes solids, such as proppant, formation solids, sediments, debris, and wax build-up out of the flowline (an automatic 24/7/365 "pigging", hot oiling, and hot watering service using the production fluids)

  • Reduces the temperature loss in the flowline

  • Provides inline, positive-displacement, non-custody transfer measurements of gas, oil, and water flow rates

We make it easy for clients to expand their leak and paraffin deposition prevention capabilities without or with less chemical inhibition, pigging, and replacement of damaged flowlines.

Next-Generation Corrosion Prevention

The switch from a continuous mode of the transport of fluids to a batch mode prevents the formation of the stationary bed of solids at the bottom of the pipe. Also, the residence time of free water in the flowline is substantially reduced.

  • MAPS generates liquid batches traveling toward the flowline outlet without increasing the flow rate of transported fluids.

  • The MAPS inlet and outlet are connected to a fluid source and the inlet end of a flowline or gathering pipeline.

  • Fluid batches are formed in the main body using an on/off valve that makes the heavier and lighter fluid or fluids flow to the outlet through the lower and upper outlet pipe, respectively.

  • This operation is carried out without stopping the flow from the source.

The costs of thermal and chemical treatments of the flowline are reduced or eliminated. The amount of heat required to process crude oil is reduced since the production fluids are delivered to the upstream production facility at a higher temperature.

Next-Generation Flow Assurance

Paraffin deposition occurs even in short flowlines both in winter and summer. The transition to the batch transport mode enabled by MAPS-V reduces the liquid residence time in the flowline. Temperature losses are substantially reduced and the problem is prevented in a 2-mi long flowline throughout the entire year.

The advantages are clear: uninterrupted production, enhanced corrosion prevention and flow assurance in the entire gathering system—all while devoting fewer resources to maintain field output.
