  • Kick handling with losses in an HPHT environment

    Fred Ng

    In most High-Pressure, High-Temperature (HPHT) wells, margins between fracture gradient, mud weight and pore pressure are typically close, leading to loss of returns as one of the most common complications in kick handling. Operational and technical options for handling some typical scenarios—including simultaneous occurrence of losses and influx—are not unfamiliar to the industry, but application of these measures in a logical sequence can help produce successful outcomes. Case studies from HPHT wells illustrate relevant issues, including applicable mitigations and contingencies for well planning and drilling operations.
