This Course well describe in details what is the High pressure high temperature well characteristics knowing that the principle of well construction in HPHT wells are not significantly different from those used in less demanding wells, but challenges remain because of condition that limit the range of suitable materials and affect equipment performance.

The program will highlight how is the margins of error in HPHT is very small but the potential consequences of failure are great.

Over pressured formation is the most of hazard while drilling HPHT wells, so in this course we will explain the precautions and the proper drilling operation and drilling parameters should be used to have a safe margin over the high pore pressure which consider a high threaten of the drilling process.

High temperature of HPHT will lead to degrade the well control and drilling equipment, so the course is designed to describe the proper equipment characteristic and design to overcome the consequences of the undisturbed bottom hole temperature of greater than 300 F.

 

Objectives
High pressure high temperature HPHT course is designed to teach participant how to:-
• Identify the different between normal wells and HPHT wells
• Identify the effect of high pore pressure on the operation.
• Identify the effect of high bottom hole temperature on equipment and operation.
• Identify the HSE definition of HPHT well.
• Identify how is the probability to have a well control incident in normal wells with comparing by the HPHT wells.
• Describe the Gas behavior, kicks and control.
• Describe the gas solubility in OBM’s effects on kick behavior.
• Demonstrate the surface gas handling capacities and procedures for HPHT wells.
• Demonstrate the drilling and well control procedure for HPHT well programs, Training and communication.communication.
• Describe the shut in procedures.
• Describe the bull heading method overview.
• Describe the volumetric method of well control.
• Describe the stripping.
• Demonstrate the effect of high temperature and pressure on mud.
• Describe the effect of ballooning on drilling operation.
• State some about of how to manage the operation.
• Understand sample of HPHT well control procedures on semi sub application.
