Paper presented at the International Petroleum Technology Conference, February 12, 2024
Paper Number: IPTC-23211-EA
... Abstract Low resistivity pay is one of the main challenges that exist in carbonate reservoirs with complex pore structure. When hydrocarbon charging occurs, it displaces water in larger pores with lower entry pressure, leading to a complex fluid distribution. As resistivity logging is based...

Paper Number: IPTC-24196-MS
... these uncertainties a real-time resistivity inversion coupled with the near-bit-gamma ray and litho-density image interpretation were used to map remote conductive boundaries and to provide invaluable information on the reservoir structural architecture. A geo-navigation model was created using offset well gamma ray...

Paper Number: IPTC-24332-MS
... conceptual tools were tested in UBCTD in attempt to acquire LWD data. The tested LWD tools are GR, Acoustic and Resistivity where the trial was simulated in a real coiled tubing drilling environment. Such tools consist of a set of devices dedicated to obtain certain measurements, these are developed for Gas...

Paper Number: IPTC-24461-MS
.... Abstract Low resistivity low contrast (LRLC) pays can contain significant additional reserves for the producing wells in decline. The most common tools for the LRLC formations analysis are triaxial resistivity and Micro-Imaging logs. However, such logs may not be available, in particular in the legacy...

... to irreducible water saturation (Sw irr ) as shown in ( Table 3 ). At each stage of desaturation, NMR T 2, electrical resistivity, and dielectric permittivity measurements were performed starting from the fully water saturated state (i.e. SW1). The capillary pressure and the corresponding water saturation...

... and geomechanics. Multiple imaging sensors, including gamma ray, ultrasonic, micro-resistivity, and two different designs of density tool, were deployed in the same drilling bottom-hole assembly (BHA). The two density tools had different azimuthal resolutions (16 and 32 sectors), while the micro-resistivity...
