HALLIBURTON AND CHEMOSTRAT INTRODUCE THE INDUSTRY’S FIRST WELLSITE FORMATION CORRELATION CHEMOSTRATIGRAPHY SERVICE
DALLAS, Texas - Halliburton Company's (NYSE: HAL) Sperry-Sun Drilling Services and Westport Technology Center International, in alliance with Chemostrat Ltd., announced today the launch of their LaserStrat™ service, the industry's first wellsite chemostratigraphy service. The successful completion of the first deployment for North Sea operator Veba Oil & Gas Netherlands has demonstrated how this "formation fingerprinting" service can bring the powerful correlation technique of chemostratigraphy out of the laboratory and to the wellsite, where it can be used to assist with critical drilling decision-making in near real time. Sperry-Sun is a product service line of Halliburton Energy Services, Inc., a business unit of Halliburton, and Westport is Halliburton’s independent E&P service laboratory.
"The LaserStrat service has the ability to provide the industry, for the first time ever, with rapid-turnaround elemental analysis of cutting samples for chemostratigraphic correlation at the wellsite," states Jody Powers, president, Halliburton Energy Services, "which can help our customers make more informed drilling decisions, such as picking casing and coring points. This innovative new tool can also aid in geosteering, save time and money, and minimize risk during drilling operations."
The rapid-turnaround chemostratigraphic correlations, typically produced within 30 minutes of samples being collected from the shale shakers at the wellsite, are made possible by combining Sperry- Sun’s global wellsite expertise, Chemostrat's proven know-how in the interpretation of whole-rock elemental data, and the LaserStrat service spectrometer's compact size and advanced laser-based technology. Westport supports the LaserStrat service by providing a full range of laboratory-based petrology and sedimentology services to enhance chemostratigraphic interpretation.
"Chemostrat has used chemostratigraphy to solve a number of correlation and reservoir development problems in petroleum basins worldwide," says Tim Pearce, director, Chemostrat Ltd. "Now, in alliance with Halliburton, we can combine our geochemical expertise with their drilling operations and reservoir characterization capabilities to bring chemostratigraphy to the wellsite, where it can positively impact drilling problems."
The LaserStrat service can be used as a stratigraphic tool to confidently identify horizons and as a look-ahead tool for drilling operations by providing chemostratigraphic correlations to offset wells in near real time. The tool also allows more confidence when choosing coring and casing points and total depth and can be useful in recognizing expanded sedimentary sections, unconformities, and faults by identifying the "fingerprint" of specific zones or horizons. If sophisticated interpretations in particularly complex intervals are required, LaserStrat data can be quickly transferred via Sperry-Sun's INSITE® rig information management system to Chemostrat or Westport for integrated expert evaluation.
Veba Oil & Gas Netherlands recently tested the "real-time" application of chemostratigraphy successfully during development drilling in an offshore field in the Dutch North Sea. The primary objective in using the LaserStrat service was to detect a critical casing point in Tertiary shales just above the Chalk Field reservoir section. This objective was achieved, and the further application of chemostratigraphy assisting in geosteering ("chemosteering") in horizontal wells is presently being tested during continued drilling in the same field.
"The robustness of the LaserStrat tool, the rapid turnaround time, and the favorable cost-benefit relation make this method a viable competitor to conventional wellsite biostratigraphy," says Andreas Hofmann, senior production geologist, Veba Oil & Gas Netherlands.
Halliburton Energy Services provides products, services, and integrated solutions for oil and gas exploration, development, and production. Capabilities range from initial evaluation of producing formations to drilling, completion, production enhancement, and well maintenance – for a single well or an entire field. With more than 300 service centers in more than 90 countries, Halliburton possesses the global perspective that is increasingly important for energy exploration and production.
Halliburton Company, founded in 1919, is the world's largest provider of products and services to the petroleum and energy industries. The company serves its customers with a broad range of products and services through its Energy Services Group and Engineering and Construction Group business segments.
Chemostrat Ltd. was founded in 1994 to provide industry-oriented, professional chemostratigraphic services and has its main offices in Wales, United Kingdom. Its correlation services are based mainly on laboratory-based chemostratigraphy studies using ICP spectrometers, and these services have been used to solve correlation problems in most of the world's hydrocarbon-producing basins.
