Lucian provides assessments of the current producing, drilling and completion practices to validate a party's claims of upside and/or independently identify areas of upside by recommending improved operating practices and capital utilization, which can then be used in valuation modeling.  He has experience in taking new discoveries from a fast tracked early production operation through full field development including waterflood implementation and assesses reasonableness of proposed development planning from a cost, timing and execution perspective.  Alternate recommendations will be made where current practices can be improved delivering greater production reliability and efficiencies. Review of effectiveness of maintenance and mechanical integrity programs to quantify potential for upsets or downtime that could negatively impact property valuation.  Recommendations to mitigate potential problems will be provided.  Current custody transfer, allocation and measurement protocols will be evaluated and assessed for accuracy and adherence to standards.

  • Drilling operational supervision

  • Drilling well design and optimization

  • Workover and re-entry design and optimization

  • Drilling cost estimation and well programming

  • Drilling budget preparation 

  • Rig, well equipment, and drilling services contracting and scheduling

Beau provides assessments of the current drilling, completion and workover practices to evaluate seller’s proposed upside. I can independently identify areas of potential upside by recommending improved drilling practices and showing the impact of continuous improvement on well costs over time, which can then be used in reservoir economic modeling.  He utilizes recent, latest-technology US horizontal well and multi-pad drilling experience to evaluate economics and feasibility of implementing these techniques globally, given the length and breadth of my engineering and supervisory experience.  He also offer insights of working in a managerial role and achieving goals in a joint venture structure.  Recommendations for standardized, fit-for-purpose, well designs will be provided in order to simplify contracting and procurement and optimize well costs.
