How Well Service Manager™ (WSM) Software Works

Weatherford provides several tools for identifying exceptions to normal well operations and trends to predict irregularities so interventions can be scheduled for proactive maintenance or repairs. When an event requires an action, WSM software is used for planning, scheduling, data collection, and job evaluation.

The WSM module allows you to manage the process through every stage of a well intervention.

Planning

Once it is determined that an action is needed, planning begins. A corrective or maintenance plan is created for the undertaking. The job plan contains each task needed to complete the intervention properly. Details are specific and planning times are based on historical information of similar work for that field.

Well information includes each component’s history of repair and replacement along with the exact components that are currently in the well. That way, the planner knows what has worked in the past and the crew knows exactly what they are going to find. No surprises.
The costs are automatically estimated as tasks are entered into the plan. The estimate can be used to verify rig crew expenses.

Scheduling

When the plan is entered into the system, you have all the information to schedule the job. Since expense and revenue deferral are not the only factors to consider you can effectively prioritize pending tasks using cost, availability, and location parameters. By having visibility of assets and crews, you can take advantage of circumstances where an idle rig can be used for a lower-priority job without delaying the higher-priority job due to location and availability.

Scheduling interventions needs to remain fluid to be most efficient. The operator must be able to quickly adapt to unforeseen circumstances that threaten to lower the efficiency of rig and crew utilization. This can only be accomplished with complete visualization of the entire field and the information WSM software provides.

Data Collection

The WSM module allows you to collect data from the field while jobs are going on. That gives you up-to-the-minute recognition of the progress of the tasks which allows you to accurately pinpoint the completion time of each activity. With that knowledge, you are able to evaluate job progress, reschedule assets, and manage the entire process with a clear vision of the activities.

Crews use a mobile computer to update job progress and time is only editable by authorized managers. That means the crew must update the computer when passing from one task to another. The time on the jobs are recorded as they are started. The field workers must update each task upon completion which immediately updates information for the field office manager.

The manager can see updated parameters that include dates of service, dates waiting, work and waiting hours, costs associated with each aspect of the project, vendor information, and rig detail including current location and wellbore equipment with run life. All events that occur at the well are tracked. They include everything from a morning safety meeting to site preparation, chemical treatments, pulling rods, and anything else that occurs at the well. The system is fully customizable, so any task that needs to be done can be easily added to the program.

Job Evaluation

By displaying jobs and assets on an easy-to-follow screen, the manager can track individual task times, see where each resource is being used or underused, reschedule to improve efficiencies, and ultimately reduce the total amount of assets needed. The necessary information is displayed in an intuitive interface that not only tracks the progress of the actions, but displays the estimated costs incurred with the projects.

Seeing work progress ensures that tasks are done efficiently and assets are used optimally. Analysis tools such as ad-hoc displays and trends are available to study job correlations. Additionally, the program can be linked to LOWIS™ software to compare job effects on well performance to historical data. This provides the ability to evaluate the cause and effect of well interventions to changes in, or cost of, production.
