 When depth is critical, Be on your Mark with
SpectraMark®Services. In many completion
situations, positive and precise depth correlation will ensure
safety, increased reliability, and reduced costs. Whether
correlating flush joint casing, non-magnetic tubulars, through
multiple strings or casing or expected "noisy" collars due to
age or corrosion, an economical solution utilizing radioactive
markers can mean the difference between guesswork and reliable
correlation. Protechnics, the worldwide leader in oilfield
radioisotope technologies, is ready to assist you with
precision correlation through its SpectraMark®
