North Kathana
Project Details
The North Kathana Block covers an area of 12.20 km² and it is located north of the Kathana Field and close to the Cambay Field, about 15km northeast of Khambhat town. The field was discovered in January 1976 by ONGC with well NK #1 which proved to be an oil bearing with 43% water cut within EP-IV (lower) pay of Kalol formation. Further, two more wells have been drilled viz., NK #2 and NK #3 were dry and abandoned. Subsequently, in the year 2001 field was awarded under Production Sharing Contract and since then GNRL acted as Operator representing contractor partner with JV partner M/s. Gujarat State Petroleum Corporation Limited.
Field after being taken over by the then JV in the year 2003, revived the well NK #1 and kept it under regular production. In 2007, JV has drilled two exploration cum development wells viz., NK #5 and NK #4, which established the hydrocarbon potential of Deccan Trap and Olpad formations. Currently, GOGL is the sole party comprising the contractor under PSC pursuant to the assignment of PI held by GSPC to GOGL vide PSC amendment executed on August 2021. As of date, GOGL is the operator for the field with 100% PI.
Acquired advanced pulsar neutron logging in NK #1 during June 2022 to identify the anticipated water contributing zone within in the formation and also to assess the upside hydrocarbon potential like bypassed oil/low resistivity pays in the well which could not have been identified conventional logs. However, logging of olpad intervals could not be accessed for logging due to temperature constraints.
Based on the ELAN inputs, hydrocarbon potential in EP-IV (U) of interval from 1832 to 1843m shows an argillaceous sand with some effective porosity development and recommended for testing and hydrofracturing job for optimum production.
As of March 2022, cumulative production from the field was 48 Mbbl of oil primarily from EP-IV layers out of proved in-place reserves of 15.17 MMstb of Oil.
The North Kathana field is covered by a 3D seismic survey that was acquired on behalf of GSPC by GT in 2005. The survey covering the whole field area is part of a 3D survey that covers 151.07 km², which is in general of good quality.
