HP/HT

This paper identifies current development paradigms and discusses the future challenges in well planning, product development, and regulation.

The engineering, design, qualification, and implementation of drilling, completion, production, and intervention equipment for high-pressure/high-temperature (HP/HT) developments present significant challenges.

This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability.

Despite hostile wellbore conditions, an operations team overcame challenges of drilling-fluid design and management to drill the first ultrahigh-pressure/high-temperature (HP/HT), deep-gas well offshore Malay Peninsula.

Well control training programs for deepwater drillers and key rig personnel are undergoing a major overhaul that has been years in the making.

A new measurement-while-drilling (MWD) tool has been designed that can operate reliably at 200°C and 207 MPa, providing real-time direction and inclination surveys, azimuthal gamma ray, annular and internal pressure while drilling, and shock and vibration measurements.

This paper posits a design method for subsea equipment governed by American Petroleum Institute (API) Specification (spec.) 17 (and particularly 17D).

Technologies in our industry are constantly advancing from more-thorough consideration for improving designs and from findings that emerge from focused research-and-development activities.

This paper describes the planning and execution of use of mud-cap fluid in the drilling of an ultranarrow-margin (0.50-lbm/gal window at the planning stage) high-pressure/high-temperature (HP/HT) well from a jackup rig.

The paper discusses two gas/condensate-development projects offshore Vietnam that deploy managed-pressure-drilling (MPD) technology.
