HARMATTAN CO-GEN SYSTEM

The Harmattan Co-Gen project is being implemented in three stages in an existing gas plant in Southern Alberta. Each stage consists of adding one Solar Titan gas turbine and Rentech waste heat recovery system . The waste heat recovery system includes an auxiliary burner to allow the waste heat recovery boiler to increase steam output by a factor of two from what was available from the turbine exhaust alone. With the addition of each stage of the system, the operator is able to produce 50,000 kg/hr of steam for the existing gas plant and to produce 14 MW of electrical power for use in the plant and for sale into the provincial grid. Seidlitz Engineering was part of an engineering team consisting of three consultants who provided all engineering services for the project; Seidlitz was responsible for all mechanical engineering services for this project.

ONION LAKE ENHANCED RECOVERY PILOT

The Onion Lake oil field is a heavy oil field located in Saskatchewan. In order to evaluate this field, a two well steam stimulation pilot was implemented by the Owner. This included water treatment and once through steam generation facilities, production facilities and pipeline system to distribute steam and gather production. In order to expedite the completion of this installation, the steam generator was procured in China and shipped to Canada; this required a significant effort to ensure that the steam generator would be acceptable to the regulatory authorities in Saskatchewan. Seidlitz Engineering Ltd. was responsible for all process design, detailed design, coordination of procurement, preparation of cost estimates, preparation of construction specifications and management of construction.

BATTLE CREEK HEAVY OIL BATTERY

This project consisted of two new oil batteries and associated pipelines to tie-in heavy oil wells near the town Consul, Saskatchewan. The oil from this pool has an API gravity of 10, a very low gas oil ratio but a significant foaming problem. The wells produce with a water oil ratio in excess of 10. A tank battery was selected as the most suitable due to the very long residence times needed to break the foam and the emulsion. Natural gas fuelled tank heaters were use to heat the production. Each battery consisted of one inlet tank, three final treat tanks and one water skim tank. Water disposal pumps were installed at each battery. Each battery was capable of 60 m3 of oil per day and up to 800 m3 of water per day. The batteries have operators on site during the day shift only. Due to the high fluid flow rates, an advanced computer based monitoring system was provided to monitor for emergency situations, to alert the operators by telephone of alarm status and shut down equipment, including some of the pumping wells. Seidlitz Engineering Ltd. was responsible for the facility and pipeline design, procurement of materials and equipment, regulatory applications, and project management.

STOWE CREEK GAS PLANT

An existing gas plant was purchased by an Operator. It was producing 340 e3m3/d of sales gas and 25 m3/d of condensate. The Operator drilled several wells and required modifications to increase the facility and pipeline capacity of the system to 625 e3m3/d of gas and 50 m3/d of condensate. The additions included 20 km of pipeline ranging up to 168 mm, a 600 kW gas compressor and various modifications to the process operating conditions to optimize the utilization of the existing plant equipment. Subsequent modifications to the plant included the addition of a second 600 kW compressor, a free water knock out and skim tank and doubling the water disposal capacity. Seidlitz Engineering was responsible for the complete process evaluation, process design, mechanical design, cost estimates, regulatory applications and preparation of all construction specifications and drawings.

BENJAMIN CREEK SOUR GAS WELL FACILITIES

The Client is the operator of a sour gas well in the Benjamin Creek area of Alberta. The well was to be connected to an existing gathering and processing system. Since the well was sour (4% hydrogen sulphide) and was located in a provincial forest area heavily utilized for recreational purposes, every aspect of the design, the regulatory approval and the installation was subject to exacting scrutiny. As a further complication, the majority of the pipeline route was over mountainous terrain and in rock. The installation included a line heater, sour gas flaring facilities, extensive emergency shut-down equipment and a complete Supervisory Control and Data Acquisition (SCADA) system to permit remote control of the well. The pipeline was externally insulated to minimize heat loss. Seidlitz Engineering was responsible for facility and pipeline design, cost estimates, preparation of all regulatory applications, obtaining all bids and awarding all contracts, construction management and co-ordination of the diverse interests of three government departments and four other oil companies.

REDWATER OIL BATTERY AND GATHERING SYSTEM

This project consisted of a new oil battery and associated pipelines to tie-in approximately 30 oil wells near the town of Bruderheim, Alberta. The wells were low productivity wells with low reservoir energy. This area consists of a unique sandy loam soil with numerous farms. A key requirement of this project was to minimize the impact to the surrounding land owners. Well site sizes were minimized and access to the wells was by means of informal trails. The field was electrified using buried cables rather than the conventional overhead power distribution lines. Extensive use was made of geotextile and filter fabric material at the well sites and the central battery site to minimize soil disturbance. To enhance well productivity the backpressure on the reservoir was minimized by installing a polyethylene annulus gas gathering system in parallel to the steel emulsion gathering system. The central battery has a inlet capacity of 100 m3/d and a storage capacity of 550 m3. Seidlitz Engineering Ltd. was responsible for the facility and pipeline design, procurement of materials and equipment, regulatory applications, and project management.

ELMWORTH WATERFLOOD

This project consisted of the addition of several oil wells and a water injection system to an existing two well battery. Equipment added to the battery included a new inlet header, source water receiving facilities and a 100 kW variable speed injection pump. All of the equipment added to the site was unitized to minimize site labour. Oil well and water injection well tie-ins required about 6 km of 89 mm pipeline. Seidlitz Engineering Ltd. was responsible for all facility and pipeline design, procurement of materials and equipment, regulatory applications, coordination of utilities, cost and scheduling management of the project and construction supervision.

MALMO GAS FIELD DEVELOPMENT

The Malmo project involved the development of a low pressure conventional natural gas field and coal bed methane resource in central Alberta. Six compressor stations and 30 km of pipeline were installed along with all other associated facilities to produce gas from 30 wells. The entire project took place in a period of less than 6 months. Seidlitz Engineering Ltd. provided all engineering and procurement related services for this project as well as scrutinizing and approving all invoices from suppliers and contractors during the installation of the required facilities and coordinating the activities of 4 field inspectors.

ENTICE GATHERING AND COMPRESSION SYSTEM

The Entice field in Alberta, Canada has primarily low volume, low-pressure gas wells. This project utilizes ploughed-in polyethylene pipe as gathering lines to make the project economically feasible. The use of polyethylene pipe for lean, low-pressure gas gathering is well established in Alberta, but this project extended the scope of its use through the adoption of technology developed for larger water lines. The field was a "grass-roots" development with no initial facilities in place. Production capacity reached 1.25 million m3/d in 18 months. Currently, there are approximately 150 wells with metering facilities, 200 km of polyethylene gathering pipelines, 40 km of steel transmission pipelines within the field and 8100 kW of compression in five stations. The facilities are in an area of relatively dense population so noise and emission impacts have received close scrutiny. Seidlitz Engineering Ltd. was responsible for facility and pipeline design, procurement of materials and equipment, regulatory applications, and project management.

BASSANO BATTERY

This project consisted of an oil battery sized for 635 m3/d of oil and water and 80 e3m3/d of gas. The installation included a free water knock out, two gas fired heater treaters and an electrically driven solution gas compressor. Also included was water settling tanks, inlet testing and metering facilities and truck loading facilities. All equipment was installed on precast concrete foundations or screw in anchor piling. All equipment was modular but interconnecting piping was installed in the field and the entire system was housed to minimise freezing problems. Seidlitz Engineering Ltd. provided all design services, cost estimates, material specifications, procurement co-ordination, regulatory applications and assisted in construction supervision and commissioning.

ALDER FLATS GAS PLANT

This project consisted of the addition of a 565 e3m3/d gas compression and processing plant to an existing 425 e3m3/d gas processing plant. The equipment added included a slug catcher, 1040 kW compressor, a modularised processing skid, hot oil heater and 30 metre flare stack. Included in the addition were modifications to the existing plant to correct various deficiencies. The entire project was completed within 4 months. Seidlitz located and purchased new compression and processing equipment which was already completed or partially fabricated and available for sale in order to make this schedule possible. Seidlitz Engineering was responsible for all aspects of the design, regulatory applications, detailed engineering, procurement, construction supervision and start up co-ordination for the project.

THUNDER LAKE GAS PLANT AND PIPELINE

This project involved the installation of a 170 e3m3/d gas compression and processing plant and 18 km of pipeline. The compressor was a 525 kW fully skid mounted and housed two stage unit. Initially, an auto-refrigeration (choke) plant was installed to permit production of gas while the well flowing pressures were high. When the well flowing pressures declined to a point where there was insufficient pressure for the choke plant, a mechanical refrigeration plant designed for operation at temperatures of minus 37 degrees C was installed. The installation of the choke plant resulted in a significant postponement of investment during the initial period of operation. An LPG mix condensate product was produced. Expansions occurred over a period of 10 years consisting of the addition of two compressors, doubling the horsepower at the site, the plant capacity was increased to 255 e3m3/d and an amine system was installed to reduce the carbon dioxide levels to acceptable levels. Seidlitz Engineering Ltd. provided all design and specification services for the facility and the pipeline system including the review of various development options, preparation of all cost estimates, applications for all permits to install and operate the facilities and procurement services for equipment supply and installation contracts.

GOLDEN SPIKE GAS PROCESSING PLANT

A gas sweetening and dehydration plant located in the Golden Spike area of Alberta is operated by the Client. The plant is one of the few in Alberta which recovers sulphur from the amine vent using the LoCat process; this process eliminates completely all sulphur emissions from the plant. Seidlitz Engineering Ltd. provided plant engineering services. These included a thorough evaluation of plant safety features and recommendations for improvements, evaluation of options for addition of compression to the plant, assistance with operating problems, preparing and maintaining as built drawings, evaluation and recommendations for improvements to emergency flaring system and assistance with regulatory submissions.

BONNIE GLEN GAS PLANT OPERATION REVIEW

Indian and Northern Affairs administers oil and gas operations which take place on Indian Reserves. They requested a review of the operations and costs which were being claimed for the processing of Indian gas in the Bonnie Glen gathering and processing system. This study included a review of the plant processes, a metering and product allocation review and an estimate of operating and capital costs for the facility.

NOVA TECHNICAL AUDIT

NOVA operates the main natural gas transportation system in Alberta. The Facility Liaison Committee is an organization formed to review industry concerns with NOVA. On behalf of this committee, Seidlitz Engineering, together with several other consulting companies, completed a technical audit of the methods employed by NOVA to design their facilities. In addition, an evaluation was completed of how effectively the present system is utilized and a comparison was made between NOVA costs and industry costs for typical facilities. Seidlitz Engineering assumed primary responsibility for the evaluation of the utilization of the existing system and for the evaluation of the design methods.

PLANT PRODUCTS ALLOCATION AUDIT

A client was requested by a plant operator to repay in excess of one million dollars for what was claimed to be an over allocation of products from a gas processing plant. Seidlitz Engineering completed a detailed review of the various allocation methods being considered and completed an alternate evaluation which reduced the amount to be repaid to a fraction of what had been requested. The study was completed with the intent that it could be submitted as evidence should legal action become necessary.
