Abstract

Kalol has nine pay zones and is a multi-layered field in Gujarat, India. Oil and gas are found in pay zones II, III, and IV, while oil is found in pay zones V, VI + VII, VIII, IX + X, XI, and XII. Water injection is being done through 104 wells at 2119 m³/d in pay zones K-III, V, VI+VII, IX+X, and XII. Horizontal, multi-lateral, and high-angle wells, microbial enhanced oil recovery technologies, PDB technology, hydrofracturing, stimulations of tight sandstone layer, and increasing the quantity and quality of water injection for effective pressure maintenance and improving the recovery factor are some of the technologies that have been tried to maintain the oil production rate from this Brownfield. This research has examined novel ways for developing the field to maintain and improve production levels in order to maximize the recovery from the field with minimal capital and operating expenditure.
