Pore-Pressure Estimation by Use of Mechanical Specific Energy and Drilling Efficiency

SPE Drilling & Completion, 2017
Summary Estimates of formation pore pressure before and while drilling are important inputs for well planning and operational decision making. A method is proposed to determine pore pressure from a combination of downhole drilling-mechanics parameters and in-situ rock data with the concept of mechanical specific energy ...

Improved Calculation Model of Mechanical Specific Energy Based on Single-Cutter Rock-Breaking Mechanism

SPE Journal
Summary As oil and gas exploration progresses to ultradeep and 10 000-m depths, insufficient energy supply during rock breaking by downhole polycrystalline diamond compact (PDC) bits presents a critical challenge. Quantifying the energy consumed in PDC cutter/rock interactions is therefore essential for enhancing bit efficiency and ...

Method for Pore Pressure Estimation Using Mechanical Specific Energy and Drilling Efficiency

IADC/SPE Drilling Conference and Exhibition, 2016
Abstract Pre-drill prediction of formation pore pressure and pressure detection while drilling to recognize deviations from the expected pressure are important inputs for well planning and operational decision making. A method is proposed to determine pore pressure from a combination of downhole drilling mechanics ...
