The Tsimiroro oilfield in Madagascar is a heavy oil resource located in the Western part of the country. There is a pilot facility currently producing
approximately 80 m3/d of 15 API gravity oil from 25 wells utilizing steam injection to thermally stimulate the reservoir. The next phase of the development is
to increase production to 1,600 m3/d over a period of several years. Some of the unique challenges of this project include working in a very remote part of
the country with no industrial infrastructure and accommodating a pronounced wet and dry season in undulating terrain with a propensity to
severe erosion. Seidlitz Engineering prepared the project design memorandum and the implementation plan to achieve this objective. As well, a program was
developed and implemented to gather fluid properties in the field. This project is progress at this time.
RUSSIAN GAS FIELD DEVELOPMENT PLAN
A Russian oil company secured concessions in southern Russia, near Kazakhstan. There were eleven fields identified for development which were distributed
along an arc over 200 km in length. The produced gas contained significant quantities of hydrogen sulphide, carbon dioxide, hydrocarbon condensate and water.
Seidlitz Engineering was requested to provide a study to identify the optimum development strategy for this area taking into account technical feasibility as
well as development cost. It was determined early in the study that the number of gas plants would have to be minimized in order to reduce development costs.
A 1400 e3m3/d gas processing plant was already in operation and it was determined that this would serve four of the fields. The remainder of the area
consisting of seven fields over a 100 km distance was to be developed with one or two gas plants. The target gas rate for the new development was an
additional 4250 e3m3/d. The terrain in this area is hilly which presents significant problems in the design of the long gathering system.
The various pipeline options were evaluated using computer programs to determine the operating characteristics of the pipelines and the requirements
for the processing plants. During this study twelve options were examined with two options being presented for final consideration by the Owner.
Seidlitz Engineering Ltd. provided all engineering services, computer modelling and cost estimates for this project.

Also included were facilities to treat and dispose of the natural gas and water produced in association with the oil. This is a very undeveloped part of Africa so all camp, electrical power generation and distribution and other supporting infrastructure was included in the plan. Seidlitz Engineering Ltd. working with several other consulting engineering companies provided a detailed development plan, specifications for the major equipment and material and a cost estimate for this project.
ALBANIAN HEAVY OIL FACILITIES
A Canadian oil company secured concessions for heavy oil in Albania. As production levels approached 2,000 m3/day, various production facility additions became necessary. Seidlitz Engineering was retained to provide engineering services including the design of an expansion to the existing oil treatment plant, the development of a tanker truck hub and 12 km insulated pipeline to optimize oil movement and an oil transport study to allow for the ocean export of current and future production volumes. Since many of the oil reserves were too heavy to be produced economically without thermal stimulation, a steam injection pilot project was implemented. Seidlitz Engineering Ltd. provided all engineering and design services, cost estimates and material specifications for all of these projects.
ISSARAN FIELD DEVELOPMENT
The Issaran oil field is located in eastern Egypt. The oil in this area was very heavy with API gravity between 10 and 15.

the preparation of various surface facility options for primary and enhanced recovery schemes. A program was developed and implemented to gather
fluid samples and determine fluid properties in the field. Evaluations were completed of the existing oil infrastructure in the area.
During the second phase of this project, central production facilities were installed to collect and clean 800 m3/d of oil and dispose of
the produced water to wells. Steam generation equipment and pipeline systems were installed to permit the injection of steam into a 7 well pilot
and to safely handle the resulting production. The second phase was completed in May 2007. The third phase included the addition of 8 steam generators
and connecting 240 new thermal wells into the production system. This phase also included a water treatment system for the steam generator source water.
