Offshore Platforms and Drilling Overview

Role of the PE Drilling Team

The PE Drilling Team is tasked with ensuring that well designs align with business objectives while addressing critical factors such as operational risks, drilling optimization, safety, and cost-effectiveness.

Key Responsibilities

Conceptual Well Design
- Developing initial well design concepts tailored to project objectives.
- Ensuring compliance with industry standards and regulations.
Project Planning and Engineering
- Engineering for unconventional drilling projects, which includes:
  - Permitting and Regulatory Reporting: Navigating the necessary regulatory frameworks to secure approvals.
  - Procurement of Goods and Services: Managing the sourcing and acquisition of required materials and services.

Drilling Program Preparation

Comprehensive preparation of drilling programs involving:

Offset Analysis: Evaluating nearby wells to inform drilling decisions.
Risk and Hazard Management: Identifying potential risks and implementing mitigation strategies.
Wellbore Trajectory Planning: Designing optimal well paths for efficiency and safety.
Pad Layout Design: Configuring the arrangement of drilling pads for operational efficiency.
Casing Design: Designing casings to support well integrity throughout its life cycle.

Technical Analyses

Conducting necessary analyses to ensure effective drilling operations:

Torque/Drag and Hydraulics Analyses: Evaluating forces involved in drilling to optimize performance.
Bit and BHA Selection: Choosing the appropriate drilling bits and assemblies for specific formations.
Drilling Fluids Design: Formulating drilling fluids that enhance performance and safety.
Cementing Design: Ensuring effective cementing operations for well integrity

Wellhead Configuration Design

Designing wellhead systems to facilitate safe and efficient operations.

Pressure Testing Requirements

Defining requirements for pressure testing to verify the integrity of the well.

Formation Evaluation Plans

Establishing plans for evaluating subsurface formations to inform further drilling activities.

Procedure Development

Creating detailed procedures to guide the construction process and ensure best practices are followed.

Maintaining compliance with all local regulatory requirements and internal PE norms and standards.
Researching drilling technologies and ensuring that PE maintains a competitive advantage through the effective use of technical innovations to maximize efficiency and reduce overall cost.
Transferring lessons learned to other drilling operations.
Providing day-to-day technical support during the project execution phase by participating in the management of change (MOC) process, providing real-time analysis, supporting Daily Drilling Reporting
(DDR), and working with the Drilling Engineering and Operations teams to adjust the drilling program

Tracking non-productive time (NPT), invisible lost time (ILT), and drilling performance in automated dashboards against pre-defined key performance indicators (KPIs).
Promoting continuous improvement and maintaining a hopper of optimization initiatives to be trialed.
Responsible for the selection and specification of drilling equipment, materials, and services while ensuring the implementation of PE’s First Time Quality (FTQ) QA/QC procedures for testing and inspection of equipment and materials.
Preparation of budgetary and project class cost estimation and well-specific AFEs (Authorization for Expenditure) in line with Repsol’s estimation procedures.
Maintaining rigorous cost control during the execution phase by generating Purchase Requisitions (PR),
Purchase Orders (PO) and Service Entry Sheets (SES) to certify drilling costs daily.
Active involvement in all aspects of Safety and Environment (S&E) from a safe well and operational designs to the verification of Safety and Environmentally Critical Elements (SECE), ensuring compliance with all internal PE S&E norms, vendor S&E pre-qualifications and audits, incident reporting, investigation and participation in Emergency Response Plan (ERP), and Simultaneous Operations (SimOps) plan activities.
Performing studies on internal and competitor data to benchmark PE’s drilling performance for technical reviews and project sanctions.
