Pseudo Dry-Gas Technology Proves Feasible and Valuable for Ultralong Subsea Gas Condensate Tiebacks
This case study describes how gas condensates within a subsea tieback system behave very differently to condensed water from a wet-gas system and therefore a pseudo dry-gas system needs to be configured differently for gas-condensate developments.
How To Design an Unmanned Minimal Floating Platform
Unmanned minimum facility platforms are a reliable alternative to traditional wellhead platforms or subsea installations, and the technologies enabling simpler designs have evolved.
Anadarko Looks to Tiebacks, Platform Life Extension, and Potential Redeployment To Add Value
Anadarko aims to maximize immediate short-cycle value through tiebacks and platform relocations in the Gulf of Mexico.
Offshore Production in the Gulf of Thailand
Oil and gas producers in the Gulf of Thailand face unique technical challenges. This review of papers illustrates some of the innovative solutions used in the region.
Statoil: Subsea Compression Systems To Extend Field Life
A closer look at the design and construction of Statoil’s subsea gas compression systems in the Åsgard and Gullfaks fields, the first of their kind in the oil and gas industry.
Mature Oilfield Facilities Enhancement: Use of Two-Screw Multiphase Pumps To Stimulate Increased Well Production
In maturing oil wells, oil production is often restricted as reservoir pressure depletes. Two case studies highlight the application of two-screw multiphase pump systems in to extend well life.
Technological Innovation Needed To Extract Value from Mature Fields
Mature fields still have value, and technology can help to capture that value through increased efficiency and reduced costs.
Life Extension of Mature Facilities Through Robust Engineering and Chemistry Solutions
The development and upgrade of mature facilities is ultimately driven by the significant shift in the composition of the arrival fluids, mainly the increasing water cut and solids production.
Optimizing Existing Separation Facilities Maximizes Recovery of Oil
The SPE Separations Technology Technical Section (STTS) hosted a special session titled “Unlocking Hidden Production Potential in Existing and Mature Fields” during the recent ATCE.
Polymer-Flood Produced-Water-Treatment Trials
Polymer flooding has been used to enhance the production of oil from mature fields in Oman. This article discusses the trial of several approaches to improve the treatment of water produced from these fields.
Innovative Solutions Enable Production Start of China’s First Marginal Subsea-Tieback Oil Field
Linhua4-1 was China’s first tieback subsea development project. To develop this marginal oil field, a number of technical challenges were overcome through a series of new technologies, and their successful development and implementation.
Experimental Investigation of Wellhead Twin-Screw Pump for Gas-Well Deliquefication
Onshore gas developments are often characterized by drilling, fracturing, and production of wells before low-pressure gas-gathering systems are in place. As well production declines, liquid-loading issues begin to appear. Use of a twin-screw pump to boost deliquefication was investigated.
Reassessment of Multiphase Pump on Field-Case Studies for Marginal-Deepwater-Field Developments
This paper focuses on the applicability of subsea processing technology employing multiphase pumps to develop marginal fields commercially. Analytical methods were used to evaluate the pumps, and the results were validated through case studies in specific fields.
Trends in Facilities Design and Construction
Operators’ demands for structural designs are changing along with the need to produce from harsher environments, deeper waters, remote areas, and marginal fields. New-builds and modifications require different approaches in assessment of cost, design, and construction.
Decommissioning Challenges in the Gulf of Mexico
Regulations are driving increased decommissioning activities in the Gulf of Mexico. Incomplete data is one of the obstacles in planning decommissioning. As fields have changed ownership over time, key information has been lost, creating challenges for the current operator.
