Deeply mining the latest logging technologies frontier is a crucial pathway for propelling the innovative development of logging technology.It is also a vital means to achieve high efficiency,precision,and low cost in oil and gas exploration and development.Based on the literature research and content analysis methods,this article has conducted sustained tracking and in-depth mining of the foreign logging industry and technology in the past two years.The oilfield open market report indicates that the global logging technical service market size has grown by 14.3％compared to 2022,marking a robust recovery and growth trend in the market.Wireline logging still holds the dominant position in the global logging market,with a share as high as 84％.Among them,SLB leads the market with a market share approaching one-third.The market concentration of LWD is even higher,with SLB,Baker Hughes,Halliburton,and Weatherford virtually monopolizing the market,collectively holding a market share of 95％.SLB significantly leads with a market share of 52.2％.Technologies have made relatively significant progress in data acquisition,processing& interpretation,formation testing,coring and perforation technology etc.Specifically,these are reflected in higher transmission efficiency with LWD,more reliable acoustic wave acquisition technology,deeper and higher resolution resistivity while drilling,smarter and lower CO2 emission of integrated and compact technology,more automation of reservoir valuation,wider application petrophysics beyond petroleum,and better coring retrieval performance etc.Combined with the current technological progress,the well logging technologies will continue to advance in the direction of promotion in intelligence and integration,breakthroughs in high-temperature and high-pressure logging technology and more reliable application in petrophysics beyond petroleum in future.
