Hindustan Oil Exploration Company Limited (HOEC) is planning development drilling of 24 wells at onshore block AAP-ON-94/1 in Tinsukia District of Assam. Oil India Limited holds the mining license for the block. The Dirok field was discovered by drilling three exploratory and two appraisal wells, which confirmed the presence of multiple gas-bearing sands. Currently, production of gas has started from Dirok-1, Dirok-2, and Dirok-4 wells. The project also involves Construction of two GGS and laying of underground transportation Pipelines. The GGS will be located at Vitor Powai village. The Proposed drill sites 1 to 12 and 15 to 18 will be located in Dirok Tea Estate and drill sites 14-19 will be located in the villages Powai Mukh and Janglu Kuruka village. The Proposed length of pipelines will be 5.5 km from GGS to trunk pipeline and 8 km from existing GPP to IOCL terminal for distribution of gas. Oil India owned Drilling Rigs are proposed to be deployed for undertaking drilling activities. The equipment required for the project will be Directional Drilling services, Drilling Pipes, Casing Pipes, Drilling Bits, Cementing services, Blow Out Preventer (BOP) and Mud engineering services. An EIA consultant has been already hired for the project. Further RFQs are expected shortly.

RFQ for the hiring of EPC contractor for GGS construction and laying of pipelines are expected by Q3:2018. RFQ for the hiring of equipment and oilfield chemicals are expected by Q4:2018.
