Historical challengesare still ongoing, and new challenges haverecently come into play. Digital is not the onlytool, but it has proven to be a key enablerin addressing the toughest challenges. over the past two decades, discuss thelessons learned, focus on some continuingchallenges, and examine how DOF canhelp the industry respond to some ofthese complex problems. DOF, if properlyexecuted, offers high-value solutions tothe industry’s high-value challenges. Thisreport discusses how digital technologypresents opportunities now and for thefuture. It is impossible to address allupstream O&G topics in a single report, sowe focus on some of the most urgent ones. Technology innovationshave beencentral to the oil and gas (O&G)industry for several decades.Technology markedly improved discoveryand recovery and significantly increaseddrilling efficiency and accuracy, optimizingproduction and enhancing safety. Over thepast five decades, the industry introducedmany novel and cutting-edge technologiesthat helped to weather many downturns. In this report, we provide a brief historyof the digital oilfield (DOF) evolution Innovations that had a significant impactinclude measurement while drilling (MWD),new artificial lift systems, horizontal drilling,3D seismic, SCADA and automation, multi-phase metering, geosteering and rotarysteerable drilling, advanced reservoirmodeling and simulations, and fracturing.However, in the last decade and a half,as digital transformations were rapidlyimpacting many industries, the O&G industryfailed to accelerate its transition to thedigital age. During the height of oil prices,a decade ago, the industry’s operatingefficiency was declining, and the returnon capital invested did not match otherindustries, impacting investor sentiments.As a result, the downturn in 2014 was severeand lasted for years. Ironically, the O&Gindustry was an early adopter of digitaltechnology starting in the early 2000s —they should have capitalized more on digitalinnovation to drive faster transformation. Now more than ever, digital transformationis paramount to the upstream O&Gindustry’s drive to sustain the world’s A HISTORYOF THE DIGITALOILFIELD —1.0 AND 2.0 The O&G industrywas one of the earliest adopters of the digital revolution, starting itstransition nearly two decades ago. At the time, the term “digital transformation” wasn’teven part of our vocabulary. With the development of web-based technology in the late1990s and early 2000s, O&G companies began to realize the power of digitalization. Althoughthe industry was an early adopter, the pace of adoption and growth has been very slowcompared to other industries. 1.0During the firstdecade of 2000’s,many companies launched digitalinitiatives under different names, such as: Smart Field, eField, I-Field,and Digital Oilfield. During that period the focus was on: REAL-TIME DATASTREAMING WIRELESSCOMMUNICATIONS WIRELESSSENSORS Upgrading wireless networks from first-generation radios to spread-spectrum radios.Using satellite technology for very remoteassets to replace outdated radio communicationsystems. A new generation of deployedradio communication technology improveddata transmission rate and speed. Satellitetechnology provided connectivity to very remoteoperations, such as drilling operations onshoreand offshore. Web-based, real-time capture of drilling datafor remote geosteering, precision drilling,and well placement in more complex drillingapplications. These first-generation internet of things(IoT) sensors were designed to accelerateinstallation time and reduce installation costsin onshore and offshore facilities. Several service companies introduced real-time data streaming of logging while drilling(LWD) and rotary steerable technology, makingit easier to drill highly complex wells. Sensors and SCADA installations is very costlyand time consuming. Onshore installationsrequire trenching. In many downstreamfacilities and offshore platform operatorsavoided deploying additional sensors due tothe logistical complexities and cost. Wirelesssensors delivered partial solutions to some ofthese problems. Web-enabled SCADA (eSCADA) and DCSsystems allowed staff anywhere and at anytime to monitor production data in real time.Operation centers were created.
