... Abstract Azeri-Chirag-Gunashli (ACG) is a giant field located in the Azerbaijan sector of the Caspian Sea. The major reservoir zones are multi layers sandstone formations and weakly consolidated where Open Hole Gravel Pack (OHGP) completions have become the standard design for production wells...

... with the project using the data as input for well completions and facility designs. The large-scale pilot equipment set consists of 3 water source wells, a pumping station and 2 water injection wells. One of the main goals of KLSP is to allow surveillance data gathering to evaluate the pilot efficiency...

... and produced (selective shut-off of zones post-production if required). This design utilized an open hole completion with compartmentalization via swell packers and fracturing sleeves. Due to the trajectory and horizontal nature of the well, electric line deployed robotics were selected to access...

... Abstract The team evaluated multiple options for conformance control, with the primary focus on shutting off water. The team broadened the focus to include gas shut off, as well as implementation in the sour gas injection wells, and the water injection wells. The new completions have become...

... Abstract The Korolev Field is located in western Kazakhstan where a waterflood pilot is planned in a sour naturally fractured carbonate reservoir. The completion design of the water supply and injection wells plays a key role in the economic oil recovery in a waterflood. An improper design can...

... of an active aquifer and a gas cap. In conditions of high uncertainties, as the geological concept of the field becomes more complex, the involvement of hard-to-recover reserves could be achieved by development of well drilling and well completion. Initially, there was information about the reservoir...

... stimulation fluid throughout the CT or tubing; both fluids are mixed at the jetting or fracturing points. Pinpoint stimulation service enables the placement of fractures with surgical precision. This technique has been successfully applied in a variety of well completions and fracturing conditions...

...-lapse gas saturation logs confirmed significant increase in vertical sweep efficiency across whole Unit-1 intervals, plus lower GOR production lasted for more than 6 years. Completion type variety in existing SGI wells, make application of chemical polymers challenging, therefore, conformance control...

... Abstract This paper presents the experience of LUKOIL-Nizhnevolzhskneft of implementation of various completion designs and continuous monitoring systems for extended-reach horizontal wells. The article describes the evolution from stand alone sand control screens and passive inflow control...

Multiflash PVT package's application includes the capability to build the fluid models and calculate hydrate/wax, precipitation curves. The well...

... Abstract As the BHQ-field matures, sustaining well productivity throughout its lifespan requires an essential need to focus on the field's well subsurface integrity. Wells in BHQ that were completed with Glass Reinforced Epoxy (GRE) tubing have been undergoing a unique and targeted monitoring...

... Abstract The late stage development of ACG field poses new challenges that can be addressed through completion technologies associated with new or improved methods of surveillance using Multidetector Pulsed Neutron (MDPN) instrumentation. In this paper we will describe the techniques developed...

... Abstract Proper design, installation and evaluation of sand control completions is vital for ensuring sand control integrity and mitigating against production deferrals due to sanding events. This is becoming increasingly important in the ACG Field, located offshore Azerbaijan, where wells...

... monitoring, which enables real time decision making. Since it is dealing with only one fluid phase (gas) it provides more certainty. Information gathered from DTS will have a strong impact on field development planning, pressure maintenance, as well as smart completion designs. production monitoring...

... focus has been to propose and develop workflows that integrate several surface/subsurface subprocesses and automate the entire workflow. In cases where significant investment is made to complete smart wells with remotely controlled inflow control valves (ICV), reservoir sweep becomes decisive when...
