Shallow Light Architecture: A Viable and Cost-Effective Solution for Marginal Reserves in Tunu Shallow Development

Abstract

Abstract The current development of Tunu field level has reached a mature level. Finding target for new wells with adequate reserves to pass the economic cut-off limit has been a challenging task. In addition, with the recent low gas price environment, completing these marginal wells using currently proven Gravel Pack (GP) well design makes these wells uneconomical. Answering the challenge, and with alignment to cost culture program, Total E&P Indonesie launched a collaborative project aiming for cost-effective wells against well reserves. Shallow Light Architecture (SLA) well design was introduced as the outcome of well architecture simplification process. For sand control, a successful period of trials of chemically-enhanced sand consolidation has boosted the confidence to implement sand consolidation on the industrialization phase as primary sand control in SLA wells. This paper aims to describe a brief development of the technology, implementation, and results for the operator.
