The report presents the OAO "LUKOIL" experience in development and implementation of the uniform system of planning, acceptance, documenting, quality control of the performed works and reliability of interpretation results, creation of databases of flow tests and tracking surveys.
Sakhalin Energy has selected a non-conventional cutting-edge completion approach to maximize recovery of the Lunskoye and Piltun-Astokhskoye fields. The original Piltun-Astokhskoe field development strategy included multiple oil zone commingled single completions and smart water injectors. Smart injectors allow selectively inject into up to four separate zones through a single 140 mm (5.5”) completion string. Every zone is isolated with a packer, has a surface-controlled downhole flow-control valve and a pressure-temperature gauge.
