(FDP) for a green Tight Sandstone Gas Condensate field in Oman thru effective fit-for-purpose full-field compositional dynamic simulation (history matching and prediction), leaded to selection of the optimum surface and subsurface development scenarios.
•Matured 5.1 BCM from Contingent Resources (CR) into Developed Reserves by proposing a way to use existing plant compression (NFA), delayed investment of new compression (outside current Business Plan), reduced required compression capacity and CAPEX (saved $40M).
•Reduced development wells project CAPEX thru well-spacing optimization and wells UR/NPV creaming analysis (6 wells less than previous FDP), saving $70M.
•Achieved new appraisal projects (Horizontal wells with massive fracs) for supper tight gas reservoirs to reduce the gap to the Top Quartile (TQ).
•Reviewed all historical PLT data of matured gas fields, optimized effective acquisition frequency, reduced number of candidates by 40%, replaced by fingerprinting (C-Isotopes) measurements, saved $0.6M of well OPEX.
•Initiated effective Tight-Gas Sandstone fractures modeling techniques in full-field simulation model to optimize frac economic sensitivities. Optimized number of fracs for 12 new wells, saved 30% of wells completion CAPEX.
•Created a methodology to narrow down the uncertainty ranges of hydrocarbon-in-place and ultimate recovery, built tank models for 17 layers using dynamic data from 160 wells.

effective integrated well-testing strategy, included multi-rate PLT, Flow-After-Flow, PBU (PTA) and SBHP all in one intervention, saved $250K per year.
•Authored new standardized PTA/PLT interpretation guidelines, trained nine junior engineers on it, eliminated hiring a contractor, and saved $150K.
•Leaded a reliable black-oil/compositional single-well Radial simulation study, diagnosed weird pressure transient responses (condensate blockage, layering, limited-entry, no flow boundaries).
•Spearheaded a multi-disciplinary team to initiate in-house full-field compositional-simulation model, optimized number and locations of infill wells, completion strategy, and production forecast.
•Built well-models for 90 wells, investigated VLP issues, proposed solutions for liquid-loading wells.

a new guideline to select the right reservoir-saturation monitoring technique (Sigma, C/O, CHFR) based on a comprehensive technical and economical comparison study.
•Proposed and implemented a new design of Deliverability test for low permeability gas wells instead of the conventional long Modified Isochronal, decreased the testing time by 60%.
•Validated the 3D reservoir modeling study of Port Fouad Marine Gas Field (history matching phase) done by Eni Italy in 2006.

the reservoir management tasks of a peripheral water injection project in a mature oil field for pressure maintenance. Optimized reservoir saturation monitoring strategy.
•Initiated a new proposal to use CHFR log instead of conventional Sigma log in one of the oil fields after observation of failed Sigma results in reservoirs with low formation water salinity.
•Developed and delivered artificial lift pump design (ESP, Sucker-Rod) for more than 50 oil wells.
•Steered 120 onsite well-intervention jobs: Cased hole logging (PLT, RST, CNL, WFL, TDT, CHFR, USIT, CBL), Smart completion, DST, stimulation (Frac, Acidizing), MDT (pressure & sampling), perforation (WL & TCP), sand control, and slug tests.
