The Schlumberger XL-Rock large-volume rotary sidewall-coring service closes the gap between core plugs from continuous conventional core and wireline-conveyed rotary sidewall cores. Covers acquisition of high-quality data at the wellsite and its delivery within defined standards. Premium content requires special account permissions.

Sidewall Coring. Contact Us. Related Documents. Understand the reservoir rock and its fluid contents Complementing logging and wireline formation testing, sidewall coring is a faster, cost-effective alternative to conventional cores and avoids the ambiguity introduced by the depth uncertainty of drill cuttings.
Sidewall cores provide information about your reservoir rock properties that is not otherwise readily available. Drillstring and Sidewall Coring. Sidewall Coring Offerings. Selected Options. Clear All. The core is recovered as a cylindrical shaped plug of the formation.
The system operates independently from other systems on the logging truck or skid. The only input required is a source of AC voltage. A recording device is necessary for recording gamma ray correlation data. The downhole tool is controlled from the surface by use of the control panel. Rotary core samples collected by the RSCT tool can be used to provide:.
More accurate readings of porosity and permeability that reduce reservoir analysis variab Microfractures in core samples taken with percussion tools cause false readings of porosity and permeability. Reliable data for rock mechanical analysis necessary for hydraulic fracturing design, wellbore stability analysis, and sand potential prediction. Core samples are undistorted with consistent cylindrical geometry which allows a wide range of petrophysical testing and analysis.
Allows for evaluation of pre-existing formation damage by providing core samples free of distortions caused by percussion tools. Besoin d'aide?
