The assessed quality of intake water and effluent water after treatment was studied. The treated waste water quality was compared with the permissible standards prescribed by Telangana State Pollution Control Board (TSPCB) and found well within the limits. This water could be successfully utilized for irrigation and horticulture purposes. Dr. Suresh Shukla | Prof. M. A.

This knowledge base article answers the question in a simple format, for students or other information seekers. We also go into a bit more detail for O+G workers who will already have some understanding. Who are the drilling operators? A drilling operator is an oil company that has successfully tendered for, and owns the mineral rights, leases and permits to explore in a particular area. They also plan the life of the well, and specify the materials and labour needed. After a drilling plan has been approved, the operator orders the necessary materials and equipment, and recruits the contractors and service companies. The operator may be a national oil company (NOC), a public oil company, or a private one. The biggest group are the national oil companies that control and produce three quarters of the worlds oil.
