SolutionsSite & Plant

Data Historian systems integrate the "islands" of information within your plant to make the combined data set readily available to engineers and management both at their desk top and also through wider corporate production reporting and planning systems that integrate with the historian.

Having this data online and being delivered in real time means your decision makers can control multiple assets from a common location that is often remote from the operations site. Typical hard benefits that accrue are :-

• efficient resource utilisation
• reduced critical decision times
• improved efficiency for the business

In addition it has been our experience that customers commonly see many positive soft benefits that improve staff moral, for example improved communication between teams and an enhanced sense of ownership by your personnel.

Aquidata Excel has been delivering effective Data Historian systems for the last 10 years. Initially using our own technology and more recently commercially available products from OSIsoft and Matrikon (i.e. PI and ProcessNet).

By combining the wealth of our own expertise in the design and delivery of Data Historian solutions we deliver:-

• efficient project rollout
• excellent focused engineering / IT skills
• huge added value to add on applications

How do you diagnose problems where timing across a range of systems is critical, did the pump trip on a transitory high pressure or was it actually a faulty instrument somewhere else in the plant?

Our systems provide the ability to interface a range of analogue and digital inputs and set up trigger conditions with simple configuration logic to capture a time series data set from just before an incident occurs and for a configurable period afterwards. Multiple event data sets can be captured concurrently and retained on the system for management analysis via Web tools.

With an increased focus on being able to prove safe operation of plant an increasing burden is falling on management to demonstrate effective reporting procedures are in place but because of practical time constraints this can sometimes be impossible to achieve.

Checking the status of the tens of thousands of tags in a modern control system every twelve hours for being inhibited illustrates the point, it is impractical, however inhibits being in place means that the automated systems which are intended to protect the plant and personnel from unsafe operation can not do their job.

A solution Aquidata Excel has delivered for one customer solves this problem. The software scans the control system for inhibits automatically recording them as they are placed and removed.

Our software then summarise the inhibits status as reports showing at a glance how long inhibits have been in place, in what plant areas and their significance.

Implementation of the system has allowed our customer to reduce the number of required inhibits to a "handful" that can be applied for the duration of a managed work period then removed again.

Mass is the only measure that allows us to quantify flow through a plant and accurately compare inputs with outputs as the pressure and temperature regimes change.

Accurate information about flow through a process is of fundamental importance to it's cost-effective management and efficient use of the flows, especially at the point when losses may be occurring.

During the course of the data collection, measurement and process problems can be identified and solutions found.

In addition for large, geographically distributed plants mass balance techniques can be also be used to detect potentially catastrophic leaks in real-time and give control room staff warning of a failure, leaks and potential explosion.

Aquidata Excel has extensive experience in providing metering control systems to the Oil and Gas industry, projects include:-

• BP : CATS Terminal Teesside, Harding platform and ETAP Satellites Project
• ConocoPhillips : Judy platform for all J- Block assets
• DNO : Heather platform for all Heather and Broom assets
• INA Croatia : Rijeka refinery and tanker berth terminal
• Occidental Qatar : PS1 Platform and Halul Island
• Talisman : Claymore A, Piper B and Saltire A platforms
• Total : Elgin Franklin platform

We have the capability to deliver complete turnkey solution from design through to delivery and commissioning for the flow computer equipment, product quality data handling, electronic panels and the most modern metering data management systems you can imagine.

As part of the constant drive to reduce operational costs there is increasing pressure on staff to become multi-skilled thereby reducing the time available to perform maintenance and management tasks.

By providing intuitive software tools we can simplify and automate metering management tasks allowing users to work efficiently, diagnose problems faster and automatically record their work activities.

Typical applications include:-

• Online Activity LogBook
• Proof Validation
• K-Factor prediction

• Fault diagnosis through trending
• Alarm & Event management

We have delivered several Mill Control and information systems, the largest being for Scotts Mills in Omagh Northern Ireland.

This project demonstrated the diverse capabilities of our basic software toolset and skills within the company because the system provided complete ERP functionality which includes:-

• Batch Tracking
• Formulations Management
• Audit Trail
• Product Scheduling
• Plant Route Optimisation
• Real Time View
• Stock Balance Reconciliation
• Bulk Delivery Management (bins & weighbridge)
• Bag Labeling Instruction

In addition the mill supervisory linked with other plant management systems to exchange data in real time, notably:-

• Stock & Customer Order Management
• Product Formulations

Using our supervisory solution the mill management were able to automate many of the statutory reports that they have to issue, i.e. for drug tracking from delivery all the way through to the delivered batches.

Aquidata Excel has extensive experience of automating the reporting process for plant and production installations all over the world.

Delivered projects include:-

• ConocoPhillips : Judy platform for all J-Block assets
• Lundin Britain : Heather Alpha production platform
• INA Croatia : Rijeka refinery and tanker berth terminal
• Talisman : Claymore A, Piper B and Saltire A platforms
• Total : Elgin Franklin platform

Our Production Reporting systems maximise automation of the data acquisition and content validation enabling users to focus on real operational issues at one of the busiest times of the day.

Typically data reported will include production, safety, stock levels, capital equipment status, well usage, reservoir well test data and loss reports.

In areas where reserves are in decline operators are actively seeking to extend the life of existing production infrastructure by bringing in new oil or gas reservoirs.

Wherever this is happening for example the North Sea and even some areas of the Middle East like Sharjah and Dubai, the value of co-mingled products being produced has to be apportioned and attributed fairly to their owners.

To avoid the cost and disruption of adding individual separation and measurement facilities it is often possible to reuse the existing plant and then by improving the instrumentation, model in software how the different input products will change as they are let down through the process.

The results of these calculations can be used to drive a 1st pass allocation and then refined again by more sophisticated calculation offline.

To manage a reservoir effectively the engineering group need to know how each well in the formation is performing and also how this relates to it's past history.

Good well test data facilitates timely decisions about when to workover or re-drill a well, maximise usage of artificial lift resources resulting in maximum recoveries and usage of production capacity.

Also as demonstrated by our recent solution for Lundin Britain commercial product attribution can be based upon results of well tests in the right circumstances saving significant measurement equipment cost and the overhead of it's maintenance.

Traditionally data is generated by routing a well through a dedicated three phase flow measurement separator vessel to acquire performance data at different process conditions.

Aquidata Excel have standard applications for both control of well test data acquisition, definition of the stable well test period and then historical management of the reservoir well test record.

We have delivered Well Test data management systems for the following projects:-

• ConocoPhillips : Judy platform for all Judy and Jade wells
• Lundin Britain : Heather platform for all Heather wells
• Talisman : Claymore A, Piper B and Saltire A platforms
• Total : Elgin Franklin platform
• PetroCanada : Guillemot & Clapham fields
