Compression Study for Eni Bhit block comprising of 10 nos. wellheads. Dynamic Hydraulic model was developed over OLGA. Study indicates the compression requirement for each well head with its suction and discharge pressure, liquid hold-up and estimated pressure drop.

Eni Kadanwari block comprises of nearly about 24 wells coming from North, South and west location of the block. Valve station is proposed and design by PES at South, North and West location of the block. Hydraulic analysis has been to estimate the header pressure at each valve station. LP, MP and HP pressure header philosophy has been suggest to cater the maximum production from each well.

Study has been carried out for the rehabilitation of two redundant reciprocating compressors which are proposed to be installed at West valve station in series with each other. Harmonic study is performed to check the suitability of these reciprocating machines with each other.

Transient hydraulic model is used to estimate the pressure drop of each flow line. LP, MP and HP pressure header philosophy has been suggest to cater the maximum production from each well.

The objective of this study is to determine the basis for the design of downstream liquid handling facility by performing Transient Hydraulic analysis from Mehar Wells head Locations to GPF. The Study covers the analysis of various forms of slugs which includes:

• Terrain induced Slugs
• Hydrodynamic slugs
• Ramp up and Start up
• Pigging Slugs

The slugging study was performed by using the OLGA ver7.0 transient pipeline simulator. OLGA is the most versatile and powerful multiphase pipeline simulator and has the capability for both steady state and transient flow simulations.

Scope of work included the review design and estimate the maximum handling capacity of the plant with a stabilized condensate i.e. < 8 psi. Suggestions for the improvement in the optimal use of the installed instruments/ equipments, identification of the effects of HP, MP& LP gas to different plan streams. Estimation of relief load and the adequacy of flare system & development of PFD’s and P&ID’s.

FEED and Detailed Engineering design Hallini Oil production facility for Mari Gas Company Limited.

Detailed engineering design of Sujawal Gas field for Mari Gas Company limited. Facility comprises of Well Head surface facility, Glycol Dehydration Plant, Amine treating unit and Hydrocarbon dew point control unit.

PES performed sizing of all Pressure Relief valve and Blow down valve of Mehar Gas Processing Facility. Different relief scenarios are evaluated for the estimation of peak load through relief valve and fire case scenarios for blow down load estimation of processing facility. Relief load calculations and relief valve orifice sizing is performed using API 520/521 guideline.

PES carried out Depressurization and Low Temperature study for Mehar Gas Field and Flow Lines/ Trunk Lines flaring system is evaluated for the estimation of peak vapor flow rate, Orifice size, minimum vapor temperature inside pipeline/equipment, minimum vapor temperature at valve outlet and depressurization time. While depressurization of Mehar-1 and Mehar-2 flow lines to North Gathering Manifold venting system is considered. The calculation and the study is conducted as per API standards and recommended practices.

An emergency shutdown system is installed to isolate the Dehydration Plant unit-3,4 & SDHU from inlet & outlet through ESD valves and to depressurize through seven ROV’s as installed at Plant to meet any emergency and release gas in cold vent.

Scope of work of this study is to carried out Dispersion and Radiation Modeling for the sizing Flare and Vent stack header.

The objective of this study is to analyze the possibility of formation of scaling in the flow line and mitigates taken to reduce the scale formation and maintain the capacity of flow lines or pipelines.
