Video Drill String and Sidewall Coring
This Defining Series article sets out the methods of acquiring cores using drill pipe and wireline; and their analysis and role in the industry.
Sidewall Coring
The efficient way to sample your reservoir
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.
Rotary sidewall cores are recovered with miniature diamond-tipped drill bits that preserve the rock pore structure when they cut a round plug of the formation directly from the borehole wall. Because rock integrity is maintained, a wealth of geological, geomechanical, and petrophysical data can be obtained through laboratory analysis of the sidewall cores.
Sidewall cores provide information about your reservoir rock properties that is not otherwise readily available.
