.... This paper discusses a novel application of logging-while-drilling (LWD) nuclear magnetic resonance (NMR) and quadrupole sonic measurements for formation evaluation of this carbonate reservoir. The LWD NMR offers simultaneous measurement of T1 and T2, and the joint inversion of T1-T2 data provides real-time...

... of hole (POOH). For the last 5 years, despite the more challenging oil/gas reservoir pockets to be targeted, the directional and logging while drilling performance in Delta Mahakam continuously increased. The drilling statistics show that 19.5% higher on-bottom ROP has been achieved by transitioning...

... zones can be quite challenging, particularly in development wells where spontaneous potential and micro-resistivity logs are not available, because operators depend solely on logging while drilling (LWD) for achieving complex well trajectories. Furthermore, due to the prevalence of highly inclined...

.... This complexity makes pore-pressure and stress analysis difficult. To address this problem, a comprehensive reservoir-evaluation program was developed by adding formation pressure testing to the planned quad-combo logging-while-drilling (LWD) program. Pressure measurements in this development stage were planned...

... safely, drilling geomechanics techniques were applied in well LD-6, including: 1) real-time monitored pore pressure and fracture pressure with logging while drilling (LWD) technique; 2) predicted over-pressured reservoir depth and formation pressure ahead of bit with borehole vertical seismic profile...

... Abstract High-quality borehole imaging is of great value during the evaluation of borehole conditions, such as wellbore stability, fracture identification, and dip mapping. Obtaining borehole images from logging-while-drilling (LWD) tools provides real-time information and allows access...

.... It was typically performed after the well had been drilled, limiting the ability for real-time decision making. The recent advent of logging-while-drilling (LWD) DFA technology — also known as fluid mapping-while-drilling (FMWD) — allows operators to make informed and timely decisions early on well construction...

... in the calibration of field geomechanical models. Markers were emplaced in two wells in Culzean. To ensure safe and successful emplacement of the markers a real-time estimation of rock strength was undertaken using logging-while-drilling (LWD) sonic data. Key to success was obtaining the correct data for timely...
