Session 1: Pre-job Planning

The objective of this first session is to cover high priority planning topics. Taking these items into account before the hostile environment pressure and sampling job occurs will significantly enhance the likelihood of job success.

• Equipment including back-up requirements, heat testing, and adverse effect of H2S and CO2 on specific metals and elastomers
• Communication plan amongst operator and service companies, as well as across operator disciplines ranging from drilling to petrophysics to reservoir engineering
• Well design considerations including mud system design, borehole deviation and dog-leg severity, hole size optimization for all planned runs, and optimizing hole conditions
• Conveyance plan. Wireline, drillpipe-conveyed, LWD, and possibly other options should be considered

Session 2: Managing Operational Risk: Job Execution

The objective of this session is to go through job execution in extension to the job planning session. Safety throughout the operation when dealing with hazardous fluids and gas samples after retrieval becomes increasingly relevant with high concentrations of H2S. One of the main operational concerns is the risk of getting stuck while carrying out fishing operations. Conveyance methods with equipment choice will be a key theme of discussion. Execution of WFT jobs requires real-time monitoring that is necessary for achieving objectives of the formation testing job. Real-time monitoring also will be discussed.

Session 3: Fluid Analysis In Hostile Environments

In recent years, downhole fluid analysis has become a primary application of formation testing, on par in many cases with pressure testing and fluid sampling. Downhole fluid analysis is critical for the assessment of movable hydrocarbons in reservoir rocks as well as for the determination of reservoir connectivity and/or compartmentalization. In addition, novel solutions are needed for the detection and quantification of H2S, elemental sulfur, CO2, mercury, and other trace components in the hydrocarbon, whether or not these are associated with high pressures and/or temperatures. In deeper reservoirs of higher pressure and temperature, fluids become more ambiguous, rocks become tighter and more heterogeneous, and sensors become more difficult to deploy. In these environments, fluid identification and analysis is more challenging but even more critical to reservoir evaluation.

Session 4: Challenging Rocks

Reservoir quality, heterogeneity and rock stability are key factors in testing and sampling parameters. Complex rocks as tight formations, naturally fractured reservoirs, thinly laminated and highly unconsolidated sands necessitate tailored procedures and advanced tool design to ensure representative, high quality measurements in a challenging context. What are your experiences and best practices in 'Challenging Rocks'?

Session 5: Advance Interpretation, Limits of Technology and Future Trends

The objective of this session is to discuss advanced application of formation testing beyond "simple" pressure measurements and sample taking.

• Where are the limits of interpretation in extreme environments?
• What are the uncertainties in advanced interpretations in these environments?
• What are the pitfalls and case histories of success and failure?
• And how can we improve our interpretation and technology to facilitate future decision-making on our developments?
