The main basin at East coast of India, Krishna-Godavari (KG) Basin, is spread across more than 70,000 sq km. on land, shallow and deep water and holds India's highest gas reserve. Deen Dayan East (DDE) field is part of KG Basin in which lay deep HPHT tight gas reservoir that with current drilling and completion technologies can be made viable. An offshore appraisal well was directionally drilled down in Sshaped to the depth of 18700 ft MD to appraise the hydrocarbon potential of Lower Cretaceous Early Rift Fill sequences which was encountered in one of the offset wells in the same field DDE Block.Due to typical extremely tight nature of sandstone reservoir on deep gas well, hydraulic fracturing is the primary method and become inseparable technique to complete this well. Given its HPHT nature, with BHT up to 415F and in-situ stress up to 16000 psi, also the complexity of hydraulic fracturing on limited space of Jack-up rig, the hydraulic propped fracturing project become extremely challenging, both technically and operationally. In addition the limited flexibility on logistic due to short drilling time constraint, made some available fracturing HPHT technology not an option for this project, and require creative domestic solution. There were 2 independent reservoir layer were hydraulically fractured till the end of the well project, and significant gas were tested on post fracture completion from none prior to fracture. This paper illustrates the meticulous planning and preparation to design and execute the hydraulic propped fracturing for well testing appraisal purpose, as collaboration works from operator, fracturing services provider and other third party involved. The core objective of this paper is to capture all lesson learnt during this project delivery, review project operational and technical aspects, and summarize the recommendation and applicable techniques for the similar offshore HPHT hydraulic fracturing project in the future.-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
