Paper presented at the SPWLA 64th Annual Logging Symposium, June 10–14, 2023
Paper Number: SPWLA-2023-0044
... ABSTRACT Triple combo logs are important measurements for estimating geological, petrophysical and geomechanical properties. Unfortunately, wireline and advanced LWD logs are typically dropped from the formation evaluation plan for unconventional wells due to economic constraints or borehole...

... unconventional reservoirs which present very different economic and technical challenges. This has led to the development of a compact integrated LWD tool optimized for geosteering, evaluating, and optimally completing unconventional reservoirs. Azimuthal spectral gamma ray, high-resolution ultrasonic imaging...

... of mineralogy is a critical step in formation evaluation. It enables porosity and saturation computations and provides input to definition of lithofacies and lithostratigraphic units. It also contributes to completion and stimulation designs. In the context of carbon capture and sequestration (CCS) projects...

... of measurements acquired while drilling. However, this has, in general, until now not applied to well integrity measurements such as casing integrity and cement evaluation which have traditionally been acquired utilizing wireline deployment. This paper will show the results of a new drillpipe deployed tool...

... logging, which limited by the information from single extra far CLYC detector. Besides, the lower counts of extra far detector will enhance the gas saturation evaluation lower limit of porosity. Therefore, a new pulsed neutron system, which consisted of double CLYC detectors and a D-T neutron source, has...

... ABSTRACT Cement bond evaluation is a critical step in the early-life stages of newly drilled wells since it rules the way for obtaining useful information about wellbore integrity. Conventionally, this is carried out by means of a detailed interpretation of cased-hole sonic and ultrasonic log...
