Continuous Core Sampling | Cascade Environmental
Continuous core sampling is a method of gathering core samples that provides a single, uninterrupted sample from the subsurface. Unlike methods where separate samples are taken at various vertical intervals, continuous core sampling offers a more complete representation of the subsurface layers.
CCT: Continuous Coring Tool from BG Drilling
2024年2月16日 · The Continuous Coring Tool is a drilling system designed to obtain core continuously while steering the hole. The core can be retrieved using an inner tube and overshot, just like with a regular wireline system.
Wireline Coring, also referred to as Continuous Coring, is the method by which core samples are cut downhole, similar to conventional coring, with the key difference being the method for recovering the core. As the name suggests, wireline cores are retrieved through the bottom-hole-assembly and drill string to surface by a wireline winching unit,
Wireline Continuous Coring - SpringerLink
2018年5月3日 · As mentioned in Chap. 3, Wireline Continuous Coring (WCC) is a method of coring/drilling by which switching from drilling to coring and vice versa is performed via the wireline, without any conventional pipe trips required. To make this possible, both for drilling and coring modes, the same outer assembly, i.e., the Bottom Hole Assembly (BHA ...
Sonic Drilling Services | Cascade Environmental
Continuous cores are produced using a single tube core barrel and an override casing. Sonic provides the most accurate installations of multi-point (CMT-type) wells where precise-depth installations are critical. Diameters as large as 12 inches are possible, and depths in excess of 850 feet have been reached. WHY CHOOSE SONIC DRILLING?
Innovative Concepts in Wireline Continuous Coring
2016年4月20日 · These requirements, economic issues of unconventional reservoirs, and also issues of conventional coring particularly in regard to excessive trip times incurred have recently led to widespread...
In this paper, the drilling fluid is used to maintain constantly pressure acting on drill wall in pressure-holding and continuous coring technology (PHCCT), which changes the stress condition of the original hole-wall from unstable stress to stable two or three-dimensional stress, keeps hole-wall away from collapse, and is beneficial to coring f...
Wireline Continuous Coring | Request PDF - ResearchGate
2018年5月3日 · Wireline retrievable coring is a unique technology offering capabilities to full bore core, drill and convey logs in a continuous operation without tripping out of hole.
Sonic Drilling | ConeTec | Continuous Sampling
Sonic drilling is a rapid, efficient, continuous sampling and casing installation technique in most soil types. Sonic is the only drilling technique that can provide continuous cores in all overburden soils (sands, gravels, glacial tills, etc).
Continuous Core - Terratech Drilling
2022年2月1日 · Continuous core is a method of sampling that—like the name implies—provides one continuous sample instead of separate samples taken at set intervals. This can be done with any cased drilling method, but is most commonly performed using sonic technology. When continuous coring, the sampler is advanced to every interval.
