• Lead training on WinGlue and Gas lift Operations for both onshore and offshore personnel.

• Mentor Junior Engineers in Production Technology.

• Utilise Advance Valve Tester data and ensure gas lift system is preforming as designed. Occidental Oil and Gas Corporation, Muscat, Oman / Doha, Qatar September 2011 to May 2020 Engineering Advisor attached to the Asset Management Department. Directed Arab, Shuaiba, and Nahr Umr reservoir management strategy, establishing techniques to reduce stimulation and conformance issues in a highly complicated fractured waterflood reservoir. Led the injection and production optimisation in fields operated by Occidental Petroleum. Consulted with vendors to provide customised solutions for various well activities while generating project economics for well intervention and well integrity scopes. Production Operations Engineer Advisor

• Championed the WRFM team, reviews and studies, debottlenecking the water injection systems on 3 platforms increasing injection by 50000 BWPD, with a resulted forecasted oil rate gain of 1200 BOPD within 6 months.

• Designed choke models as part of the WRFM process to assist in identifying possible gas lift and power constraints for future wells. This led to a budget cost savings of USD7.5MM on adding an additional compressor, and ESP power distribution network optimisation.

• Headed the development of a theoretical Production Logging Tool, utilising petrophysical logs, FMI and Rel Perm data, successfully identifying, isolating and regaining 1200 BOPD from failed swell packer completions. Deryck Ramkalawan +447*********/adjuxq@r.postjobfree.com Page 2

• Spearheaded the engineering design, specifications and implementation of acid jetting for carbonate reservoirs, gaining 50-350 BOPD, as well as acid fracturing jobs through pinpoint stimulation technique with coil tubing in open-hole and cased-hole wells, increasing injectivity index by 300%.

• Designed and executed chemical and mechanical conformance jobs for openhole horizontal well, returning well to production with a water cut reduction of 30%.

• Reviewed underperforming wells and proposal for remedial treatment, data acquisition, lift optimisation, wellbore cleanouts, water shut-off and jet perforating, increasing wells production by 10-50%.

• Conducted in-house gas lift training, ESP design, modelling, optimisation, troubleshooting, gaslit snorkel and well straddle design, to achieve a potential gain 800 BOPD.

• Increased production from lift optimisation by 1700 BOPD and upgraded production system distribution model for improved surveillance and inferred production as part of the WRFM effort.

• Employed real time data acquisition and surveillance, well and pattern reviews, reservoir simulation, waterflood streamlines, production system performance to maintain base production and reduce field decline rate by 3%.

• Spearheaded the generation of production type curves for new and re-drilled wells using Decline Curve Analysis, rock type, geological location, historical mud losses and anisotropy data, to support drill well economics.

• Led both the Production and Reservoir Engineering inputs to Final Well Planning for 15 new wells, 3 re-drills and 5 workovers, wells performed 15% better than type-curve prediction.

• Optimised and managed waterflood patterns, generated OFM workflows, studied conformance issues and communicated with Field Operations to meet the VRR or IWR target for the field of 1.2

• Mitigated against well anti-collision issues, losses while drilling and well trajectory optimisation cutting drill cost by USD600K and drilling time by 1.25 days

• Technical authority for Well Integrity within Occidental Petroleum.

• Managed the Well Integrity multi-disciplinary team, developed and implemented WIMS, approved team objectives, prepared budgets, intervention programs, supervised planned scope and generated KPIs’.

• Resolved Well Integrity issues, generating processes, implementing best practices, formulating policies, guidelines and procedures for risk assessment, risk classification and risk mitigation of wells with sustained annulus pressure.

• Headed the development of a Well Integrity database to record and track problem wells on a monthly basis and allocated rig or non-rig resources for trouble shooting and resolving issues.

• Established casing pressure management program and field standing instruction for ESP wells, to prevent casing collapsed during early stage of production.

• Led the Well Integrity diagnostic, investigation and remediation programs to return wells in a safe condition and in compliance with international ISO 16530-1 and 16530-2 standards, within the specified timeline and saving approximately USD 10MM in rig costs.

• Oversaw cost effective repair solutions for well conductors whose structural integrity was borderline, extending conductors’ life from 4 years to 25 years.

• Spearheaded the generation of progress reports, HSE risk assessments and budget variances for intervention work resulting in both cost and time savings of USD 1MM and 12 non-rig days.
