Abstract: The present disclosure provides a managed pressure drilling method and system that accommodates timely and accurate control of surface pressure in order to maintain appropriate wellbore pressure of a well. The system and method can use a minimal set of inputs, such as a measured pressure input, with a control software hierarchy described herein to improve the accuracy of the controlled pressure and automation of drilling rig components over conventional Managed Pressure Drilling (MPD) systems. Because the method compensates for the real pressure rate of change using the pressure input, the method and system allow the implementation of MPD techniques in legacy applications and drilling rigs. The system and method can reduce human error and inefficiencies that directly degrade the quality of MPD techniques and improve wellbore drilling and hydrocarbon production performance within the industry.

Abstract: The on-board, automobile computer (MC) for the end-user includes Internet and email communication through cellular technology, along with other features. Services include MCRadio, which provides radio station listening options that are available via the Internet. Also, with the available services, email capabilities are provided (MCMail). Other options include MCInfo, which provides user-requested information via the Internet that is delivered to the user with voice capabilities. MCShop provides shopping capabilities through the automobile computer. All options are provided with voice-capabilities and/or manual operation. All of the MC options mentioned previously are available through a host computer via cellular technology, which retrieves the user-requested information and the information is sent back to the user.
