Integrated Surveillance Offshore Turkmenistan

The complete paper describes a work flow in which wells and production networks in the Cheleken Block offshore Turkmenistan are automatically modeled daily with steady-state and transient tools and ultimately analyzed by the Cheleken Block Central Data Gathering System.

The complete paper describes a work flow in which wells and production networks (15 platforms and 100 active wells located in the Cheleken Block offshore Turkmenistan) are automatically modeled daily with steady-state and transient tools and ultimately analyzed by a Web-based surveillance system, the Cheleken Block Central Data Gathering System (CDGS). These models are updated and run automatically on a daily basis by means of the CDGS.

Introduction

Well and network modeling are being used widely across the industry as a method of problem detection, production enhancement, and production optimization. However, well and network modeling require a large amount of data that needs to be systematically collected, cleaned, validated, and updated. They also require considerable manpower, because many time models are not calibrated adequately to ensure reliable results.

An operator has implemented a robust system, the CDGS, that allows data capture, validation, and approval in a systemic manner. There was a need to capitalize on this ability and integrate it with steady-state and transient models to increase the efficiency of the overall process.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 188357, “Integrated Surveillance in Cheleken Block Offshore Turkmenistan by Use of Automated Steady-State and Transient Models,” by Roberto Espinoza, Dragon Oil, and Suraj Mohan Uniyal and Ivan Marcelo Jaramillo Rivadeneira, Schlumberger, prepared for the 2017 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 13–16 November. The paper has not been peer reviewed.
