Evaluate the energy consumption of the following offshore oil and gas facility,

identify energy saving options and suggest the energy supply options to meetthe current and future demands of the facility.

You should include basic engineering calculations and analysis in your proposal.Economic analysis based on assumed cost of the proposed equipment/facility

is required for this project. You must demonstrate how you achieve yourselection and how you de-risk your proposal.

You will submit a report (approx 25 pages) and a ppt of max. ONE (1) slide onlyfor your group’s work.

Remember, you’re only part of a whole. So work together.

Group Project Guideline




MAB4633/MBB4513

An offshore oil producing facility is currently used for exploration and

production operations of an oil field, 50 km offshore Sarawak. The facility is

designed to handle 300kbpd of oil production from which 20% of the well

output is natural gas. The energy demand for the platform (LQ, motors, drilling

etc.) is 150 MW Peak. The existing power generation facility provides for only

45MW Peak at 100% loading. The facility operators need to decide on theadditional power generating options for the platform. The existing energy

scenario for the facility can be summarized in the following table:

CTR - Lab projects

Cost per person = RM60/hr

Time per person = 8 hrs/week Group cost per day = (60 x 8 x 5 )/5 = RM480/day

Ext consultant cost (Lab tech + GA) = RM120/hr x 2 = RM240

Total lab cost (10 days) = RM4800 + 240 = RM5040/lab (FIXED)

Recovered CTR = 5040 –

RM60/hr x 8 hrs/day x 200 days = RM96,000

Employee cost to company per month RM96,000/12 =RM8,000

Value Drivers Critical Success Factors

Oil production rate Good sweep efficiency

Manage/Monitor water-flood Utilize idle well slots to tap poorly drained areas

Update geological model Use of new technology – using well or seismic data - Simplified well design, fewer casing strings

- Improved history matching Knowledge sharing

Company reputation Keeping government and unions continuously engaged

Minimize Capex and Opex Communicate with other operators in the area to investigate mutually beneficial

scenarios

(oil and gas pipeline, selling facility space)

Near field exploration to increase reserves Investigate tertiary recovery methods to extend life of field

Operational Success Preventive maintenance on injection to maximize uptime

You need to learn how to (& when not to) make decisionduring conflict of situation, where information is

insufficient, outlook is uncertain, and your peers would

do everything they could to overpower you.

Plan for the worst, hope for the best but don’t over do it.
