IVM

IVM

• Increase revenue from reduced deferred production:

  • by avoiding future shut-ins through proactive repairs of root cause problems

  • by getting shut-ins back online quicker

  • by allowing user to quickly count, organize, and report recurring upsets so that they may be eliminated

• Reduce cycle times for making decisions regarding well and production initiatives:

• Dramatically shorten the time-to-value decisions for your most important assets

• Dramatically shorten the time-to-value decisions for your most important assets

• Spend more time in engineering analysis and less time on data management

• Works with existing DCS / SCADA / HMI / Data Historian platforms

Production Engineering

What production engineers enjoy most from IVM is the ability to quickly and easily analyse well problems so that corrective action can be applied before downtime occurs. Production engineers can see downhole data overlain on multiple surface data parameters to get a complete picture of well performance. The same picture can be traced over time to detect trends or deviations. Real time well performance can be quickly and easily compared to wellbore model predictions to determine when a well is not performing according to predictions.

Production engineers find IVM’s XY Plotting capabilities particularly useful when monitoring the performance of ESP’s. The actual rate and pressure performance of the downhole pumps can be displayed on an overlay of the published performance curves for the pumps to see if the pump is operating in an acceptable range. Alerts and alarms can be set any measure variable on to warn if the pump is moving into an unacceptable range.

Additionally, IVM’s computer assisted production well testing application makes it easy for the operations and production team to conduct consistent and accurate production well tests leading to more accurate production allocations and better operational decisions about the wells. IVM’s curve fitting allows the production engineer to easily manage and accurately report decline and depletion making more accurate production forecasts possible.

Reservoir Engineering

In addition to being able to see downhole pressures on wells that are instrumented with downhole gages, reservoir engineers are able to easily spot and analyze pressure buildups that have occurred whenever a well has been shut-in for any reason. This capability reduces the need for a special shut-in period to get pressure build up data.

IVM’s built in Horner Plot and MDH analysis features give the reservoir engineer a quick and easy way to calculate P* . These values can then be compared for multiple wells and can be stored and trended over time. This provides the reservoir engineer with a wealth of information not previously available since good pressure buildup data typically required a special shut-in of a well.

Also, with IVM’s data cleansing capabilities, reservoir engineers can easily prepare data for analysis using their favorite reservoir analysis and modeling tools such as Andex Energy Services, Kappa, Schlumberger, etc. Actual performance can be compared to predictive models quickly and easily.

Facilities Engineering

Facilities engineers find IVM particularly helpful when trouble shooting process performance problems or trying to optimize process performance. The ability to see performance data from the entire process at one time and to plot and trend up to eight different parameters gives the engineer and instant overview of process performance. This performance information can be compared to predicted performance from process simulators to pinpoint deviations. Comparison of real time data to predicted performance can be automated to give alerts and/or alarms when deviations exceed predetermined limits.

Facilities engineers also find IVM valuable in understanding and optimizing performance of specific equipment items. As an example, rate and pressure measurements from pumps can be displayed on an XY Plot with manufactures performance curves as an overlay. Monitoring hydraulic fluid pressures and/or hydraulic pump on/off cycle times can detect hydraulic leaks and send an alert or alarm before loss of hydraulic pressure can cause a costly platform shut-in.

Operations

Operators like IVM for its ability to display any measured parameter on easy to use displays giving them a complete overview of the operation. They especially like the alert/alarm feature in IVM. The alerts and alarms can call their attention on specific areas allowing them diagnose pending problems and take corrective before a more serious problem or shutdown occurs.

Operators find IVM’s first out capabilities extremely useful in quickly determining the root cause of equipment shutdowns. Being able to know quickly what caused a shutdown speeds the process of repairing or correcting the problems and enables equipment to be brought back on line quicker so that production losses are minimized. Analyzing trends in first out occurrences illuminates troublesome components that can then be fixed or put into scheduled maintenance programs to eliminate downtime.

Management

The online collaborative environment of IVM is used by managers to facilitate problem solving sessions and decision making without the costly delays of scheduling meetings to hear technical presentations and make decisions. Using IVM, valuable input from everyone involved can be obtained online while everyone is looking at the same data. The problem solving cycle time is greatly reduced to minimize lost production.

Managers also find IVM invaluable in being able to monitor high interest activity such as production from a new expensive well. With IVM managers can see any data element from their operations they choose to monitor.
