Live Well Display and Automated Data Analysis Improve Managed-Pressure-Drilling Operations

Ideally, a managed-pressure-drilling (MPD) system should have not only highly accurate sensors measuring critical mud-flow data and automated chokes to maintain desired annular pressure precisely but also the ability to aggregate, analyze, and display this real-time information on monitors on the rig floor and in remotely located centers. This paper describes a number of system enhancements, including the ability to display and analyze not only the critical parameters of drilling hydraulics but also other information that allows different perspectives in considering the closed-loop system.

Introduction

MPD offers a number of accepted applications while increasingly being considered for any other operations requiring precise pressure control. There has been a growing trend for MPD providers to be more involved in drilling, well-construction, and completion operations as their safety value and effectiveness is realized.

A new platform has been developed for the next-generation MPD system. The goal was the development of a user-friendly system that will improve critical decision making and execution by providing enhanced visual feedback and interaction. This may include preengineering, operation and post-job analysis, automation of time- and pressure-sensitive tasks, multiple software engines being able to evaluate limits, and multiple components being controlled in one place.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 25164, “Live Well Display and Automated Data Analysis To Improve Timely Well-Control and Drilling-Optimization Decision Making in MPD Operations” by Ferhat Gumus, Ilia Pobedinski, Don Hannegan, Khaydar Valiullin, and Douglas R.
