PDO has more than 2500 wells

operating in some the most challenging

production environments in the world.

Most wells are artificially lifted with very

high water cut. PDO’s production has

been gradually decreasing in the past

decade. New generation of automation

technology was needed to increase

production, reduce automation systems

cost and reduce operating cost. The

Oman Government imposed fees on all

licensed radio communication resulting

in millions of dollars of annual fees for

UHF radio communication network.

Only unlicensed radios operating at

less than 100 mW power were not

subject to this fee. PDO also wanted to

have ONE standard wireless Remote

Terminal Unit (RTU) to be installed on

most of its wells.

Project Scope: vMonitor delivered wireless RTUs and end-to-end Systems for all wells and pipeline facilities. The applications include:

> Water injection wells

> Gas lift wells

> Electrical Submersible Pumped (ESP) wells

> Progressive Cavity Pumps (PCP) wells

> Pipeline Block Valve Control Stations

> Gas Producer Wells

The project involved design of cluster wireless architecture with remote gateways, whereby multiple wells can communicate

to a single Gateway using low-power 2.4 GHz RTUs under 100 mW. The Gateways in turn communicate back to the central

stations using long-range wireless Ethernet radios.

Technology Innovation> A wireless RTU is designed to serve a majority of well applications.

> The most advanced cluster architecture in the industry with combination of short and long hop communication.

> Full capabilities for remote configuration of all equipment at well site.

Value Delivered: > Lowered automation systems cost by more than 40%

> Increased data bandwidth by more than ten folds.

> Lowered operating cost by more than 30%.

Client: Petroleum Development Company of Oman (PDO)

Client Challenges:


06.indd 4 05/04/2011 4:33:13 PM

Technology Innovation: > A battery-powered long-range micro-wireless sensor with a

range of over 5Km, which is a first in the industry.

> Data from well to web is delivered over the SPDC Intranet and integrated with SPDC’s current IT system and Data Historian.

Value Delivered: > Reduced production deferment by 3-5% annually.

> Reduced operating cost of maintenance and well visits by 50%.

Client: Shell Nigeria(SPDC)

Client Challenges:Estimates were that SPDC was losing

more than 4-5% of its production

annually due to deferment caused by

well shutdown problems. None of the

wells were monitored. As a result,

when the wells shut down, there were

no means of predicting the problem

or even identifying and isolating the

wells that failed. Nigeria has one

the most challenging environments

for automation technology. The two

biggest problems that all operators

face in Nigeria are theft and vandalism.

Most, if not all, well automation surface

equipments require solar power, which

gets stolen and renders the equipment

useless. SPDC had tried a variety of

technologies for a number of years

without any success. The clear solution

required small low power (battery-

powered) wireless well monitoring

equipment.

Project Scope: vMonitor delivered full service to the Client by providing system design, installation, civil work and commissioning.

06.indd 5 05/04/2011 4:33:13 PM

Client: Shell Venezuela SA, Venezuela (SVSA)

Client Challenges:

Project Scope: vMonitor delivered complete SCADA system for Wells,

including Software, Hardware, Radio Architecture and

connectivity OPC to existent DCS System.

Among the applications we can highlight:

> Gas Lift Remote Control and Monitoring

> Down Hole Gauges Monitoring

> Electrical Submersible Pumped (ESP) Control

> Battery Operated RTU

> PLC Remote Control and Monitoring

> DCS and PI OPC Connectivity

The project involved the design of cluster wireless

architecture with remote gateways in order to gather data

from battery operated wells, as well as radio equipped

panels systems for Gas Lift control and PLC monitoring.

vMonitor has been offering SCADA System upgrades

every year as part of the support program to SVSA,

introducing new system features and innovation with

every version.

During the project execution vMonitor opened an office

locally to handle Latin American Systems and nearby

application with a response time to SVSA of 24 hours.

Shell Venezuela, at the time of the

project was operating at the South

Western side of Maracaibo Lake

and had one of the most important

concessions offered by PDVSA to

foreign companies. Having to deal

with the marginal low producers oil

fields, SVSA ran optimization software

for continual improvement of the

production. Reliable Battery operated

vMonitor solution was implemented

at the oil well facilities to ensure data

was sent to the SCADA system every

5 minutes. Safety concerns and control

needs to optimize Gas Lift Manifolds,

led to the application of remote control

using vMonitor’s SCADA system,

TotalAccess. At this time, all Gas

Lift Wells are controlled remotely by

the SCADA system using vMonitor

Telemetry system.

Technology Innovation: > A battery operated wireless J/O unit with

3 sensor connections that have very low power consumption and up to 2 years of continuous operation of the battery when the RTU is set to transmit every 5 minutes.

> Intranet based SCADA system as a Door opened to the wells and flexible connectivity to third party systems. including Shell proprietary Fieldware and Production Universe Software Solution.

> Remote control Valves with max. operation at latency of 2 seconds for 25 km links

Value Delivered: > Reduction of operating cost by more

than 20%. location, saving cost on transportation boats.

> Reduction of Operator intervention in Gas Valve location, saving cost on transportation boats.

> Production increase due to Optimization Data has been calculated at 15% of gross production.


06.indd 6 05/04/2011 4:33:14 PM

Client: Shell Gabon (Gamba Field)

Client Challenges:

Project Scope: Remote Automation for 40 Gas lift wells, 2 ESP pumps and 3 Gas measurements using non-intrusive gas meters connected to

vMonitor’s hardware. Monitoring Process and diagnostic data on SCADA and interface to PI management system.

Project Execution:vMonitor delivered full service to the client by providing system design, installation, civil

work and commissioning. vMonitor executed the project under Shell supervision with no interruption in production while all

their wells were producing.

vMonitor executed the installation of equipment using a crew of 5 people including the supervisor. One single Gateway was

used to gather all data, using one repeater in the field for farther wells.

Gamba Field was one of the first Oil

fields to be explored in Gabon and

has been producing for more than

30 years. Fading of this reservoir has

been increasing in the past 10 years;

therefore, Shell Gabon was looking

for a way to control natural production

downgrade by monitoring integrity of

the wells. Ninety percent of the field

is Gas Lift Injection with compressors

and pipes running up to 15 km long.

Gas Lift Injection efficiency has been

a struggling part of operations with

downtime of compressors occurring

often. vMonitor implemented a

monitoring system to measure Gas

Lift Flow at the wells site and at 3

major branches of the transportation

pipes, making it possible for Shell to

understand their gas consumption

around the field. TOTALACCESS

SCADA Application was installed to

make all remote data available in PI.

Technology Innovation: > Radio transmission was possible using low power modules transmitting over dense

vegetation (25Mts trees) for up to 6 miles. Remote Antenna Tower height was just 6 Mts to achieve efficient communication.

> Automated data visibility from well to PI, going through TOTALACCESS SCADA System in the client network.

Value Delivered: > Reduced production deferrment by 3-5% annually.

> Reduced non-supervised shut down of wells.

> Improved Gas Lift Optimization

06.indd 7 05/04/2011 4:33:15 PM

ADCO had set aggressive production

increase goals of more than 40% over

the next five years. The production

increase would come as a result

of two major initiatives: new fields

development and increasing production

from existing fields. In order to increase

production from existing fields, ADCO

had launched a major initiative called

I-Field (Intelligent Field). Remote

well monitoring and control are key

requirements for ADCO in the I-Field

initiative, especially for wells with

Electrical Submersible Pumps. ADCO

tried to use Satellite based remote

monitoring systems for ESP wells, but

with limited success, so they turned

to vMonitor to deliver a more reliable

wireless remote operations solution.

Client: Abu Dhabi Company for Onshore Oil Operations (ADCO)

Client Challenges:

Project Scope:vMonitor provided an end-to-end integrated wireless remote monitoring and control system for ESP wells, including hardware

and software in the office to monitor all parameters of the ESP pumps, generate daily reports, diagnostics and alarms. vMonitor

delivered the first successful wireless remote monitoring system for ADCO. The system is delivering daily reliable data on the

ESP wells.

Technology Innovation: vMonitor delivered the first successful wireless remote well monitoring system in the Middle East using GPRS technology, the first system in ADCO from well to desktop.

Value delivered:> Potential to increase production by more than 5%.

> Reduced well visits by more than 50%.


06.indd 8 05/04/2011 4:33:15 PM

ADMA had faced a major challenge

in trying to increase production for

a number of years in its offshore

operation. Its fields have a large

number of Water Injection wells and

the reservoir engineers had never been

able to properly manage the injection

process since they did not have any

data from the Water Injection wells.

Several attempts had been made to

install wireless SCADA systems, but

they had always failed. The previously

installed systems were not reliable and

could not deliver data for distant wells

that were more than 20 Km or more

from the main platform.

Project Scope:vMonitor delivered the first successful Water Injection wireless remote monitoring system for ADMA. vMonitor provided

wireless sensors for monitoring well pressure, temperature and flow. The wireless sensors installed on wells deliver the

data to a data concentrator, which in turn transmits the data (over 20 Km in distance) to the main platforms where vMonitor

TOTALACCESS software receives and processes the data. The data from TOTALACCESS is then accessed via ADMA’s intranet

system.

vMonitor delivered end-to-end system including hardware and software.

Client: Abu Dhabi Marine Operating Company (ADMA-OPCO)

Client Challenges:

Technology Innovation: vMonitor delivered the first wireless sensor system ever installed in ADMA. This is the first wireless Telemetry system in ADMA capable of capturing data for wells over 20 Km in distance.

Value Delivered: > Water Injection data from wells will be critical to increasing

production.

> Reduced well visits by more than 60%.

06.indd 9 05/04/2011 4:33:16 PM

Chevron Nigeria was losing a lot

of oil production due to production

deferment. When wells shut down,

the operators lacked the capability

to identify which wells were shut

down, so they had to visit every well,

therefore required sending choppers to

every platform, which was extremely

costly and inefficient. Chevron could

not install any wireless SCADA system,

because historically solar panels were

stolen or sabotaged. So Chevron

needed a battery operated wireless

system to monitor the well pressure,

temperature and flow; and to check the

well status and be able to predict well

problems.

Project Scope:vMonitor delivered end-to-end system including hardware and software.

vMonitor provided battery powered wireless well monitoring system to monitor well

pressure, temperature and Gas Lift flow. The system transmits data every seven

minutes back to the main platform. The data is captured by vMonitor TOTALACCESS

and is integrated with Chevron’s SCADA system (Wonderware).

Client: Chevron Nigeria

Client Challenges:

Technology Innovation:> vMonitor delivered the first functioning wireless battery

operated SCADA system in Chevron Nigeria’s history.

> We delivered the first battery powered flow meters (Partial AGA) in the industry.

Value Delivered: > Potential to increase production by 7-10%.

> Significant reduction in downtime by identifying shut down wells.


06.indd 10 05/04/2011 4:33:18 PM

ExxonMobil Nigeria has been a

major production and corporate HSE

compliance challenge. The Nigeria

offshore fields have a tremendous

potential to increase production.

However it was not possible to achieve

production increase without the ability

to monitor well operations. There were

also significant production losses due

to well shut down without any ability

to isolate the problem and predict

well failure. Furthermore, ExxonMobil

had set a goal to install pipeline leak

detection technology to meet certain

HSE objectives. However, ExxonMobil

had not been able to implement a

remote monitoring system since all

previous SCADA systems running on

solar panels had been subject to theft

and sabotage.

Project Scope: vMonitor delivered an end-to-end wireless battery-powered system for well remote

monitoring and pipeline leak detection. The system was installed on Nigeria’s

offshore operation. The objective of timely delivery of well pressure, temperature

was met. In addition, the system provides continuous pipeline leak information

using inlet and outlet pressure data.

Client: ExxonMobil Nigeria

Client Challenges:

Technology Innovation: This was the first battery powered pipeline leak detection system in the industry.

Value Delivered: > Potential to increase production by at least 3%.

> Significantly reduced HSE risks due to pipeline leakage.

06.indd 11 05/04/2011 4:33:19 PM

Saudi Aramco had put forward an

aggressive production increase plan to

achieve more than 12 million barrels

per day production within a few years.

This production increase was planned

to be achieved as a result of new field

development as well as implementation

of the I-Field strategy which called for

installation of smart well equipment,

like downhole smart well technology,

Downhole gauges and other advanced

well technology, as well as the

implementation of surface wireless

remote monitoring technology and

software in the office to integrate the

well data with reservoir and production

optimization software. At the time of

the project there were few wells being

remotely monitored or controlled in

Saudi Aramco.

Project Scope:vMonitor delivered in the Abqaiq oilfield a two-way

wireless remote operation system for well monitoring (and

in the future for well control). The system was integrated

with downhole gauges that monitor downhole pressure

and temperature. The Downhole gauges were provided by

two companies: Schlumberger and WellDymanics.

The vMonitor wireless RTUs integrate to the surface

system of the Downhole gauges and transmit the data

back to the office where vMonitor’s TotalAccess software

is installed. TotalAccess provides well data access

to various Aramco engineers (reservoir, production,

operations, etc.) on a continuous basis.

Client: Saudi Arabian Oil Company (Saudi Aramco), K.S.A. - Abqaiq OIfield Well Monitoring

Client Challenges:

Technology Innovation: > vMonitor provided the ability to link to

various Downhole gauge systems from multiple vendors in a single integrated wireless system and software.

Value delivered:> Providing the enabling technology to

implement the next generation I-Field strategy which has the potential to increase production in the Abqaiq field by more than 10%.


06.indd 12 05/04/2011 4:33:22 PM

Saudi Aramco Jeddah and Yanbu

refineries at the time of the project

had tank level monitoring systems,

however there was a need to

implement a redundant tank level

monitoring system to ensure a high

level of safety. The redundant system

had to be wireless and easy to integrate

with the current switch level system

and the DCS system already in place.

The technological challenge was that

the wireless system had to be battery

powered, but also report by exception

in case of an alarm. Reporting by

exception requires that wireless system

be continuously running in very low

power state in case of tank switch

level incoming. All battery operated

wireless systems traditionally could

not do reporting by exception because

it required the RTU to be continuously

powered, which depleted the battery

power supply.

Project Scope: vMonitor delivered wireless tank level monitoring systems to Jeddah and Yanbu refineries. vMonitor delivered the latest

generation of vMBus Micro units. These units are battery powered and able to report by exception.

Client: Saudi Arabian Oil Company (Saudi Aramco), K.S.A. - Refinery Tank Level Monitoring

Client Challenges:

Technology Innovation: We delivered the first battery powered wireless system capable of reporting by exception.

Value Delivered: > Redundancy in safety.

> More than 75% in savings over conventional tank level monitoring systems

06.indd 13 05/04/2011 4:33:24 PM

Pemex’s longest pipelines stretch over

hundreds of kilometers in some of

the most difficult territories in Mexico.

There had been many incidents of theft

and sabotage in the pipelines in addition

to several operational issues which

had caused Pemex to lose billions of

dollars annually. Pemex was looking for

a new generation of wireless sensor

technology to monitor these remote

stations and to link the data into their

existing communication backbone.

Those wireless sensors were the only

way to implement such a system due

to the fact that they could not run

cables through these stations because

of the extended distances in those

rural locations and that some of those

stations were on private property.

Pemex also required the data from that

wireless system to be fully integrated

with existing Pemex SCADA through a

special Pemex Modbus protocol.

Project Scope: This project demonstrated vMonitor’s true capabilities to

deliver a complete system in an incredibly short period.

vMonitor delivered base stations with complete shelters

to receive data from the wireless sensors, integrated base

stations to Pemex existing communication backbone,

integrate the data with Pemex SCADA system through

Pemex Modbus protocol.

vMonitor mobilized an entire team to Mexico, and worked

flawlessly with the local contractor to deliver a functioning

system on time. vMonitor had to overcome serious

technical and logistic challenges since the pipeline stations

were scattered throughout a very large area and inside

private properties.

vMonitor delivered the complete system in less than 2

months.

Client: Petroleos Mexicanos (PEMEX), Mexico

Client Challenges:

Technology Innovation:vMonitor delivered the first wireless sensors in the industry capable of output for valve control.

Value Delivered:> Increased pipeline security and

environmental safety

> Theft prevention

> Reduced visits to locations by more than 90%


06.indd 14 05/04/2011 4:33:25 PM

Lyondell Tank farms had a hard-wired

monitoring system for High Level

alarms that was providing the alarming

information (and in some tanks also

the actual level reading) for years. This

hard-wired monitoring system had

presented failures and a project to

recondition it had been approved. The

problem arose due to the required time

span for the project completion: the

refinery operations could not be delayed

until the project was completed. They

required a monitoring solution that

could be deployed quickly and with a

high trust level.

Project Scope:vMonitor delivered a successful wireless monitoring system to Lyondell Refinery

in two phases. The system not only shows the High Level alarm, is also capable

of indicating the real battery voltage on each sensor and when a communication

failure has been detected between the master station and any of the remote high

level sensors.

Client: Liondell Refinery Tank Level Monitoring

Client Challenges:

Technology Innovation: A wireless sensor was designed around one of vMonitor Wireless J/O units capable of reading 2 analog inputs, 3 digital inputs, and configurable to work continuously ON or in a low power mode to save battery life.

Value Delivered:The client was able to monitor its high level alarms with a very economical system that was installed in short time (compared to the cost and time required to install a wired monitoring system).

06.indd 15 05/04/2011 4:33:28 PM

Shell US in Colorado has a large number of wells that

needed to be monitored. However due to the location of

these wells in the Rocky Mountains area, most wireless

systems would not work because of the mountain terrain

obscuration. Furthermore Shell required a low power

battery powered RTUs, because the snow cover would

render solar panels ineffective during the winter months.

Project Scope: vMonitor Supplied vMBusX-S battery powered RTUs and

OPC software interface to Yokogawa DCS. These units

have been functioning reliably now for several years.

Client: Shell United States

Client Challenges:

Technology Innovation: The first battery powered spread spectrum based

wireless system that could deliver data in such a

complex terrain

Value Delivered: > Timely well data

> No data is available on well production since

those were experimental wells

> Reduced well visits by 70%.


06.indd 16 05/04/2011 4:33:30 PM

PDVSA (Petroleos de Venezuela) had

started the process of Remote wells

automation more than 10 years ago,

and were continuously looking for

better ways to control Gas Lift Injection

at well head manifolds offshore in

Maracaibo Lake. Having to deal with

offshore constraints and limitations, the

most important challenge for PDVSA

had been to ensure accurate reading

and control of Gas Wells Injection,

where power is a limitation. For this

reason, vMonitor developed a Solution

RTU Flow computer that calculated

Gas flow based on AGA standards and

controled a valve injection actuator on

a timely basis. This means that the

control algorithm runs at interval times

configured by the user to save solar

energy as much as possible without

losing control over the process.

Project Scope: vMonitor delivered RTU Flow computers. Project was performed by a partner local

agent. Flow Calculation and control algorithm were developed based on customer

specifications and inputs of process specialists.

Client: Petroleos de Venezuela

Client Challenges:

Technology Innovation: > Flexibility to work under severe weather conditions on

NEMA 4x enclosure.

> Smart low power Flow computer with configurable execution algorithm for energy saving, even using external display and key pad function

> Sleep key pad mode.

Value Delivered: > Continuous control over process.

> Power savings running system on 40 Watt small solar panels.

> Improve Gas lift optimization
