The UCH gas field owned and operated the by Oil & Gas Development Company Limited (OGDCL) is located in Tribal Dera Bugti Agency District of Baluchistan Province in Pakistan. The distance from Sui to UCH is about 73 Kms. The nearest city is Jacobabad, which is about 73 Kms from UCH gas field. OGDCL developed the UCH-II gas field and assocated processing facilities in order to deliver gas to the UCH Power Limited (UPL-II power Plant). The UCH-II SCADA system is designed to monitor and control the 15 Wellheads and the UPL End station. In addition it provides the process data related to third-party systems. Each RTU will gather the field data from the field devices, and send the data to the SCADA Server using radio communication. The RTUs use a Siemens S7-300 PLC, the programming software implemented is Siemens STEP 7 V5.5. The RTU will convert the data from the Field Devices into its own memory, store, calculate and then transfer the data to the HMI Application on the CCR servers. The HMI Application will also be able to send command to the RTUs to activate ESD functions at the wellheads.

The project was successfully finished in June, 2015.


MIGAS Production Validation Pilot System:

In August 2004, TRC was awarded a contract by P.T. SUCOFINDO for an "Oil&Gas Production Monitoring and Validation System" Pilot Project for the MIGAS - "Ministry of Energy Indonesia". The Pilot Project is designed as a basic implementation of the complete "National Production Monitoring and Validation System" functions. The Pilot Project was successfully completed on December 2004 and will be operational for one (1) year.
The project was successfully finished in May, 2007.



n 2001, TRC was awarded a contract to provide a SCADA System for Pakistan Petroleum Ltd to monitor and control their Kandhkot Natural Gas Field operations. The SCADA system consists of one (1) poller/server PC (main terminal unit – MTU), six (6) new RTU stations and six (6) interface to the existing Moscad RTUs. The SCADA Control Room was located in the Dehydration Plant – DHP and the six (6) new RTUs are installed in the wells 6, 10, 11, 17, 23 and 12.

The MTU uses Wonderware InTouch MMI software to collect data from the new RTUs via VHF radio communications and to interface with the existing Moscad FIU in the same control room to collect the existing RTU stations’ data. Pressure, temperature, flow rate, valve status, CI pump status and other signals are collected from the wells. The Moscad FIU is used to collect data from the existing Moscad RTUs via VHF radio communications and pass this data to the SCADA MTU over a serial link. The Integra TR radios from DataRadio Corp. were used to establish the VHF radio links between the control room and the new wells.

The new RTU stations are based on Modicon Compact RTUs with AGA-3 capability.

Fisher-Rosemount static, differential pressure and temperature transmitters are used to collect field signals.

TRC was responsible for the design, engineering, system configuration, software development, system integration, and test and installation supervision and commissioning of the system



ARCO Indonesia, a production sharing contractor to Indonesia’s state oil company Pertamina, has awarded Praxis Houston a $3.8Million EPC contract to provide an integrated Gas Automation Control (GAC) System for key production platforms in the Offshore North West Java (ONWJ) Production area. The GAC System gathers gas delivery data from these platforms through a redundant SCADA System with Industrial SQL servers and RAID arrays. As part of the contract, Praxis will provide duplicated Control Centers, both Onshore and Offshore. Under normal operating conditions, the entire GAC System is operated from the new Onshore Control Center in ARCO Indonesia’s Jakarta office. If communications between Jakarta and the Offshore facilities are severed, the Offshore Control Center assumes automatic control of the GAC.

The system provides seamless integration of Decision Assistance to the operator through the use of Predictive Control Technology from LIC Energy. Through the use of Real Time Dynamic Process and Pipeline Modeling, Survival Times are calculated when abnormal events trigger the Decision Assistance Tree (DAT). Eight hour look ahead scenarios allow the operator to take early corrective action and thus ensuring uninterrupted gas supply to the National Electricity Company, PLN, who supplies electricity to Jakarta. On-line gas chromatographs provide an essential tool to the operators to keep the gas BTU value and CO2 concentration between contractual limits by utilizing the new SCADA system as a back bone to implement remote compressor control at the central off-shore compression platform to achieve optimum gas blending capabilities.

The GAC System runs on Wonderware’s release 7.0 of Factory Suite under the Microsoft NT 4.0 operating system. Four servers, incorporating dual 200 MHz CPU’s and RAID arrays form a powerful computing environment, and ensure that the 24 operator nodes provide instant response to operator requests. The Advanced Control System from LIC Energy runs on two DEC ALPHA workstations and interfaces to the SCADA system through a high-speed TCP/IP link. Under the terms of the contract, Praxis assumed “turnkey” responsibility for the design, installation and commissioning of the system within a 46 weeks time frame.

The need to optimize gas production quality and delivery is an overall goal for ARCO Indonesia. The present market conditions are pushing operators to develop marginal fields, which are in effect a subject of ever-increasing interest to the Oil and Gas Industry. One of ARCO Indonesia’s business strategies is to further develop marginal fields through the use of not normally manned facilities in order to reduce investment and operating costs. “Praxis was awarded this contract on the basis of their ability to supply us with this technically complex and sophisticated system”, said Mr. Budi S.L., Planning Engineer for ARCO Indonesia. “We will be one of the first companies in the Pacific Basin, to utilize Predictive Control as a tool to improve and optimize gas production”, he said.
