Through the use of Sekal's DrillScene I am responsible for the realtime monitoring, capture and analysis of drilling operations on multiple wells simultaneously to reduce risk and prevent lost time incidents through analysing developing transient operational trend deviations relating to Torque & Drag, Hydraulics, ECD/ESD, Holecleaning and Swab & Surge.Through the use of Sekal's DrillExpect uniquely specialised transient physics based deterministic simulation software I can be predictive in ensuring that rig operating limits and downhole mechanical, hydraulic and geo-pressure limits are not exceeded. I can simulate scenarios to optimise parameters, practices and procedures to reduce rig time and reduce risk of failure and loss.Examples include simulations to optimise holecleaning parameters, circulations & well clean up at TD and optimised tripping speed profiles both with and without flow/rotary whilst maintaining within the Geo-Pressure window. In addition more routine T&D sensitivity analysis is also provided to our clients.Even smaller scale operational practices such as pump start-ups (analysing gel breakdown surge pressures) and staging flowrates (for ECD and mudloss control) can be reliably simulated and applied for safer and quicker operating procedures.Highly advanced simulations for CML and MPD operations are also performed as are operations with hydraulic flow split and bypass including Hole Openers, Circulation Subs and Surge Reduction tools. Multi fluid simulations including displacements, cementing operations and of course complex Swab & Surge are also performed by myself.Our valued clients are major operating companies including Equinor, Shell, OMV Petrom & OMV Global, Var Energi, Wintershall DEA, BP, Woodside Energy, OKEA & Petronas.

Using drilling engineering, analysis, display, visualisation & optimisation software I maintained vigilance of rig operations & perform comprehensive well analysis. As remote Rig Site Drilling Engineer I proactively communicated with Rig Supervisors, Office Drilling Engineers & Service Company vendors to inform & mitigate against identified drilling risks; in particular those associated with Kuwaiti development wells.I made predictive engineering calculations & created roadmaps, plan vs actual & statistical analysis of drilling parameters & well data, T&D, Hydraulics, ECD & Swab/Surge; aided by offset well data study.Where available I undertook drilling dynamics shock & vibration risk monitoring, analysis & mitigation for optimising drillstring reliability.Parameters were checked by myself against operating limits for WOB (buckling), Torque, SPP, ECD, PPFG (Swab/Surge) & DP/tubular yield stress. I was also responsible for independently monitoring & verifying equipment & well control barrier pressure testing as per API, IWCF, IADC & KOC standards & procedures.I made drilling parameters statistical analysis to optimise ROP through “sweet spot” determination; aided by use of drilling efficiency optimisation measurements/calculations & graphical outputs including MSE & Power Curves.I provided proactive prediction, detection, analysis, early warning & mitigation with knowledge capture/lessons learned. Recommendations were then made to operations.I performed drilling operations & rig activity statistical analysis for benchmarking operating KPI’s including drilling/tripping connection speeds & identifying/verifying NPT/ILT sources with improvement recommendations. This was performed daily, by run, hole section & for the entire well operations time-scale.I collaborated & provided feedback for DE and DS&E teams bridging the gap between KOC's defined Operations & Drilling Engineering divisions. I was KOC's E&P Software Optimisation Taskforce Member for RTDDC.

I was assigned as RTOC Lead Engineer, responsible for real-time monitoring, intervention & optimisation of all rolling ENGIE offshore global drilling projects. As part of a team I provided a service new & previously unfamiliar to ENGIE with corporate level buy-in & collaboration which would later become the model for real-time service delivery by Halliburton for all future real-time projects. I reported directly to the Global Head of Well Operations & was trainer/mentor to team mates; as well as administrator & technical guidelines/procedure writer.The job was a combined role incorporating responsibilities of Sperry SDL, ADT & DE Services.I provided a service focused on Well-Control, Drilling Engineering, Drilling Mechanics/Dynamics, Drillstring Integrity, Holecleaning & ECD Management, Hydraulics & Torque & Drag Optimisation.I optimised performance & risk mitigation for OFS down hole drilling equipment requiring a working knowledge of tools from Sperry, Baker Hughes, Weatherford, Pathfinder, Schlumberger, Gyrodata & Transmark EDS .I performed predictive modelling using Landmark EDM, checked & optimised flow rate/SPP/Bit hydraulics (HSI), Torque & Drag, effective hole cleaning, ECD & drill string Critical RPM predictions.

I was assigned to Maersk Oil North Sea UK Ltd. I supported Directional Drilling, MWD Co-ordinators & field DOE Group as required. I also shared 24hr on-call well planning duty & ad-hoc cover for the Applications Group.I was accountable for pre-planning, wellpath design, collision avoidance analysis, definite wellpath revision & wellpath monitoring using WellArchitect & CoViz 4D software as per BHOS & client instructions. For Maersk I managed two WellArchitect databases simultaneously, one using Baker Hughes' Positional Uncertainty Error Models and the other employing Maersk's "COMPASS equivalent" Positional Uncertainty Error Models. I also produced Ladder Plots in Microsoft EXCEL for EMD.I performed BHA design optimisation using BHASYSPro 3D Analysis software. Modelling included bending moment, contact forces, sag, clearance, as well as BUR for predicting/optimising dogleg capability and stabilisation for drillstring performance and reliability. I undertook simulations of actual situations at up to hole section scale including hole-opening, whipstock exits, high-local-doglegs, washouts and borehole oscillations and their respective impact.I generated bending moment predictive modelling & provision of BHASYSPro reports plus BM v DLS charts for BHA design integrity & well trajectory achievement purposes for CoPilot applications.I undertook modelling & sensitivity analysis for T&D, Hydraulics and Swab & Surge using Advantage Engineering software as required.I also had the role of Technical Support role for the UK Drilling Optimisation Group & CoPilot Services.I had daily real-time, post-run review, analysis & reporting of drilling performance responsibilities for operations meetings where I highlighted related NPT sources & areas for potential improvement. Also routine OOS evaluation was carried out as per corporate policy. I made post-run/well data analyses & project work for customers where required including AAR, CRT & IPWP.

This service was provided in both offshore field and onshore remote operations capacities. Traditionally two discrete drilling optimization services, I typically provided both services simultaneously:• Provided CoPilot® Drilling Dynamics and Optimisation service.• Provided PressTEQ® Integrated Pressure Management service.I was responsible for VSS and advanced drilling dynamics monitoring, evaluation and drilling dysfunction mitigation. I advised and instructed on best practice.I monitored, analysed and managed borehole quality optimization and downhole reliability through minimising tortuosity and BHA fatigue. I offered realtime 3D well path tracking and steering guidance to Directional Drillers using CoPilot in tandem with BHASYSPro BHA design engineering outputs. CoPilot was especially useful in complex 3D & ERD wells and in special scenarios such as sidetracking, stump avoidance and "handrailing".Drilling pressure management was another primary aspect of my job role, monitoring, modelling and optimising ECD & swab/surge during both drilling and tripping operations using PWD data and engineering modelling for ECD and tripping model calibration and roadmaps/projections.I was responsible for hole cleaning / borehole stability monitoring and management through cuttings / cavings trend analysis for hole cleaning evaluation.
