Selective coiled-tubing reentry system allows access to multilaterals
… work in live wells, allowing wellbore clean-outs, openhole-formation washes, selective-matrix stimulation, production logs , and nitrogen-kickoff jobs. Until recently, however, reliable coiled-tubing reentry techniques were not available …

Modified coiled tubing logs short-radius well
… or with short-radius wells that do not penetrate Zone 1. Thus, short-radius wells penetrating this zone and production logs are crucial to determine the producibility of Zone 1. Job planning Job planning was crucial in determining how to …

Various technologies unlock Pinedale anticline tight gas
… force also are working on production data analysis for commingled production from the wellbore by running multiple production logs over time. From these data, the teams can evaluate and discriminate reservoir permeabilities and fracture characteristics …

Swelling-rubber packer enhances multilateral viscous oil production
… torque and drag losses, even with up to 21 SRP slip-on sleeves on a long liner. More importantly, as shown through production logs and geochemical fingerprinting, all trilateral wells have maintained production from the lower zone without being …

Empirical correlation corrects fluid density logs
… water cuts. It is essential, therefore, to run production logs early in the well's life. The empirical procedure ..... the field. The logs need to be classified by the production logs according to the tool type and the same completion …

Casing-conveyed perforating improves tight gas sand economics
… Mcf. Initial production rates for each well are about 5 MMcfd with possible 7-8 MMcfd/well deliverability. Production logs verified that the low-quality sands substantially contributed to the production. These observations and the previous …

PRODUCTION LOGGING-Conclusion: Two more options correct fluid-density logs for friction
… Less popular is to do this with third-party software. Employing a service company to acquire and interpret the production logs has the disadvantage that it is often difficult to quality control the analysis or re-interpret the raw data. This …
