Forget the old days in the oil fields, with every sunrise, a new well is being drilled, and since every well has its own story ; the operation should build high reliable, safe and advanced domestic drilling rig, with international brand to meet domestic requirement of new technology that have been developing in the world ,in order to meet demands of oil exploration, and development, increase drilling efficiency, decrease drilling cost, and thus improve the overall benefits of oil exploration and development, including rotary steerable drilling, vertical drilling, casing drilling, solid expandable tubular, managed pressure drilling, and logging while drilling…etc. So what are those new technologies?
The modern drilling technology is developing toward informatization and intelligentization, combination of multi-disciplines to improve oil production and enhance oil recovery, and effectively development of special oil gas reservoirs, and that is thanks to: Logging while-drilling services has dramatically improved drilling performance and well placement–leading to increased production. Scope services set new standards for reliability and data quality, while quadrupling the data transmission rate over the industry standard.
Neoscope source less formation evaluation-while-drilling service reduces risks by eliminating the need for chemical sources in logging while drilling. The industry’s only sourceless formation evaluation-while-drilling solution. NeoScope service uses unique pulsed neutron generator technology in the shortest multifunction LWD service collar available. In unconventional plays, NeoScope service offers an extensive suite of sourceless measurements to evaluate reservoir quality, provides critical data to optimize completion quality, provides sourceless measurements in real time for better well placement, and removes transportation and handling risks and the costs of chemical sources.
The Stethoscope LWD service provides formation pressure-while-drilling (FPWD) measurements, that are used to predict pore pressure trends throughout the wellbore. Profiles generated by the service’s real-time calibration points combine with other LWD logs to model dynamic reservoir pressure, which is crucial to optimizing recovery. These pore pressure models also foster a better understanding of production systems. The use of real-time LWD measurements to predict pore pressure trends provides data assurance in any hole deviation or orientation.
A core taken from the side of the borehole, usually by a wireline tool. Sidewall cores may be taken using percussion or mechanical drilling. Percussion cores are taken by firing hollow bullets into the formation. The bullets are attached to the tool by fasteners, and are retrieved, along with the core inside, by pulling up the tool and the fasteners. Percussion coring tools typically hold 20 to 30 bullets, but two or three tools can be combined on one run in the hole. Mechanical tools use hollow rotary drills to cut and then pull out core plugs. Because the sidewall cores can be drilled from a wide variety of lithologies from hard, brittle igneous rocks to friable sandstones, cemented carbonates, and ductile shale plays they avoid the damage associated with percussion coring tools.
Coiled tubing drilling
A low-cost method drilling and completing wells attaches a non-rotating jet drilling tool to coiled tubing. After drilling, the tubing portion outside the well is cut and the remaining tubing becomes the liner or casing for the well. By also using a residual bend remover, centralizers, and injecting a thermal cement slurry, very low cost steam injector wells can be drilled and completed.
Periscope bed boundary mapping service is revolutionizing well placement by providing the ability to see the reservoir as wells are being drilled, thereby eliminating sidetracks on wells and enhancing production. The industry’s first deep and directional electromagnetic LWD measurement continuously monitors the position of formation and fluid boundaries up to 21 ft away so challenging horizontal wells can be drilled entirely within the sweet spot.
The Periscope service indicates the best steering direction, and the deep measurement range provides early warning when steering adjustments are required to avoid water, drilling hazards, or exiting the reservoir target.
Those new technologies were able to make another revolution in the oil field, where we can avoid the maximum mistakes and damages, that’s why we find that a lot of oil and gas companies have been seeking to get those methods. So nowadays, most wire line well logging jobs can be carried out in while-drilling mode, and some logging-while-drilling (LWD) sensors are good enough to compare favorably with the same kind of wireline logging tool family.
