A new firmware module has been developed for a popular series of handheld, programmable calculators. Use of the module can help to minimize the occurrence of kicks and blowouts, facilitate well-control training and certification, and assist well-planning activities.

The module can be used by all levels of drilling personnel in routine and critical situations. It is programmed to handle calculations for surface/subsea BOP stacks, land/offshore locations, gas/salt-water kicks and straight/directional wells. The engineering programmes can be run in standard oilfield or SI metric units.

The purpose of this paper is to describe both the operation and development of this module. Major emphasis is placed on the use of the module in well-control and drilling operations.
