This department has been involved in design and execution of numerous engineering and construction projects including :

Civil Engineering & Construction Department of OEOC ; apart from conducting its routine operations for OEOC ; has been giving services to different sections of NIOC including Exploration Directorate, Central Iranian Oil Fields Company and Gas Fields Planning & Development Company.

Civil Engineering

Design and construction of access roads in oil& gas exploration and production sites. Development monitoring of civil construction projects. Maintenance of roads and building complexes. Construction of Cellar, drilling rig platforms and camp sites.

Construction of water reservoir and pumping station sites.

Construction of structures for mechanical units and pipelines for supply of water to the drilling sites.

Construction of offices, residential buildings and camp sites including steel and concrete structures.

· All Civil Engineering and construction operations are carried out according to NIOC's Technical Standards and Specifications.

It is worth noting that most of the projects both in exploratory or development phases are located in remote and non-accessible areas of the country.

Given the rough terrain and geographical difficulties facing the operations; technical criteria, standards and project termination deadlines are key factors during the entire project. The cellar site cementing process has to be carried out very meticulously while the cellar hole (pit) and conductor pipe is being laid for the drilling rig to be installed on the cellar platform.

Despite the remoteness of the sites and subtlety of the operations, OEOC has been able to successfully meet the demands of its clients in the best possible manner.

Well Testing and Wireline Operations - 1

Well Testing and Wireline Operations ___________________

Highly experienced professional staff in Well Testing and Wireline Department of OEOC have been engaged in numerous testing and wireline operations on wells which have been carried out on different Iranian oil and gas fields during the last 30 years. The sites include : NAR , KANGAN , SARKHOON , GHESHM , DALAN , KHANGIRAN , GONBADLY and NAFT SHAHR.

Below is a brief description of equipment and capabilities of OEOC on well testing and wireline operations :

Full Bore Drill Stem Testing ( FBDST )

FBDST is a temporary well completion to let flow of the Well to perform production test and record down hole Pressure and temperature . Completion is done using 7 in. and 9 ⅝ in. Packers . We use one FBDST unit which consists of two sets of test strings with 5 in. OD and 2 ¼ in. ID and 15000 psi working pressure . The tools are H2 S service.

Electronic Memory Gauge ( MQG – X )

MQG-X with 1 Mb memory capacity can record 200000 data set.

Each data set consists of date, time, pressure and temperature.

Battery is of lithium type that can work up to 26 days in the hole.

Mechanical DST

To evaluate hydrocarbon potential of an un-known formation and to determine down hole pressure and temperature of such a well, a mechanical DST is used. This tool has 4 in OD and 1 3/4 ID with 15000 psi working pressure. It can be used with 5 in., 7 in. and 9 5/8 in. packers.

Mobile 3- Phase Test Separator

OEOC has three mobile separators that can each handle 15000 BOPD and 75 MMSCFD gas and 2000 BPD salt water.

Each separator is equipped with rupture disk and relief valve to ensure high safety.

Gauge Tanks

To measure separated liquids derived from the separator, we have 3 tanks with 100 bbl capacity. Inner surface of tanks are coated with epoxy materials to resist against corrosive agents.

Well Testing and Wireline Operations - 2

Well Testing and Wireline Operations ________________________

Transfer Pump

This equipment is used to transfer the oil in the tanks to burning pit in order to avoid oil spillage and contamination of the environment.

Wireline Winches

OEOC owns two skid mounted wireline winches for working on offshore and light jobs and three truck mounted wireline winches for heavy duty jobs on both onshore and offshore. Truck mounted winches are very advanced and equipped with computerized system called "Smart Display".

This system has capability of showing information such as depth, speed and tension to the operator at any time during the operation. It is also possible to adjust maximum permitted settings, so that when they exceed the threshold, it starts to make a sound alarm. This way, the risks involved in the operation are minimized.

To control surface pressure we have three sets of 10 k lubricator with Bop and Amos co valves.

Bottom Hole Sampler

To take bottom hole sample we use two types of sampler, Ruska and LEUTERT . with these samplers 400 and 600 cc samples can be taken .

LEUTERT sampler is new and operates as positive displacement mechanism resulting in considerable decrease of sampling time.

Choke Manifold

There are two 15 k and three 10k chock manifolds to flow the well through desired choke sizes. This is necessary for maintaining proper pressure drop on surface in order to divert the flow to the separator.

Flow Head

OEOC has four Flow Heads with 15000 psi working pressure. By using Flow Head for temporary completion; there would be no need to remove Rig Bop's. Consequently the rig time is saved and the setting of the packer is completed much easier.
