ExxonMobil and Qatar Petroleum made a final investment decision to proceed with development of the Golden Pass LNG export project located in Sabine Pass, Texas. Construction will begin in the first quarter of 2019 and the facility is expected to start up in 2024. The $10-plus-billion liquefaction project will have capacity to produce around 16 mtpa of LNG. It is expected to create about 9,000 jobs over the 5-year construction period and more than 200 permanent jobs during operations. Golden Pass awarded the engineering, procurement, and construction contracts for the project to a joint venture of Chiyoda International Corp., McDermott International, and Zachry Group.
Co-owned by Qatar Petroleum, Exxon Mobil, and ConocoPhillips, the Golden Pass LNG Terminal handles up to 2 Bcf/D of natural gass imports. Qatar Petroleum and Exxon Mobil Corp. will soon announce plans to proceed with a $10-billion project to expand the Golden Pass LNG terminal in Texas, according to a Reuters report released 1 February. The report cited three people familiar with the transaction. ConocoPhillips, the third partner in the terminal, will sell its 12.4% stake in the project and has no plans to participate in the expansion. Exxon Mobil is the most likely buyer for that stake; sources told Reuters that the plans for the project are in advanced stages and the existing partners do not want to bring in another company.
Claudio Descalzi, chief executive officer of Eni, and Saad Sherida Al-Kaabi, the chief executive officer of Qatar Petroleum, shake hands during their recent agreement in Doha. Fresh on the heels of its announcement to leave OPEC, Qatar is positioning itself to become an increasingly active player in global energy projects through minority partnerships with big explorers. Its most recent acquisition involves a 35% stake in Italian operating company Eni’s interest offshore Mexico. Late last year Qatar said that it would withdraw its 57-year membership in the Organization of Petroleum Exporting Countries and focus on increasing its natural gas production. Qatar is currently the world’s third-largest supplier of liquefied natural gas (LNG) behind Australia and the US.
Omar Mahmoud and Hisham A. Nasr-El-Din, Texas A&M University, and Zisis Vryzas and Vassilios C. Kelessidis, Texas A&M University at Qatar Summary During the past few decades, nanoparticles (NPs) have been investigated as additives to address the challenges of drilling fluids and have shown potential for application. Computedtomography (CT) scan and scanning electron microscopy energy dispersive spectroscopy (SEM-EDS) were used for filter-cake characterization. The effects of NP concentration and filtration conditions on the filter-cake properties were investigated. A highpressure/high-temperature (HP/HT) American Petroleum Institute (API) filter press was used to perform static and dynamic filtrations. Indiana limestone disks were used as filter media to simulate formation behavior. NPs/Ca bentonite fluid showed improved filter-cake and filtration properties in the presence of polymers and other additives. A concentration of less than 1 wt% of NPs is preferred for generating a good-quality filter cake. The best characteristics were obtained when using an NP concentration of 0.3 to 0.5 wt%. The NPs/Ca bentonite-based drilling fluid can withstand conditions up to 500 psi and 350 F and generate filter-cake properties of 0.151-in. NPs improved the filter-cake properties under both static and dynamic conditions. SEM-EDS showed a smoother/lessporous filter-cake morphology with less agglomeration when using NPs at optimal concentrations, which confirms that the NPs play a key role in forming a better filter-cake structure. The present work provides an experimental evaluation of the filter cake generated by modified NPs/Ca bentonite-based drilling fluid at downhole conditions, which is an extension of our previous work using a simple NPs/Ca bentonite suspension (Mahmoud et al. 2018).
The Barzan Gas Project is a critical program to deliver natural gas to Qatar's future industries. The project was expected to affect shallow coral communities during pipeline construction from Qatar's North field to onshore. To partially meet the state's environmental clearance for the project while supporting the state's national vision, RasGas developed a project-specific coral-management, -relocation, and -monitoring plan that incorporated proven methodologies to relocate at-risk coral colonies to a suitable location. In addition to natural-gas reserves, coral-reef communities are regarded as a significant and highly productive natural resource in Qatar, providing refuge and nursery areas for many commercially important fish and shellfish species during portions of their life cycle. Corals off the coast of Qatar grow in one of the more thermally stressed environments in the world.
Al Khalij field offshore Qatar is formed of a highly heterogeneous carbonate reservoir with significant remaining dynamic uncertainties. Moreover, given the current high field water cut, any operation to decrease it can have a large effect on field oil potential. This paper details the design, planning, and execution of the intelligent-completion technology in the field and covers the value generated for field development. The field, discovered in 1991, is located offshore Qatar (60-m water depth) and is adjacent to the Iranian border (please see the complete paper for a reservoir and geological description). The field was put into production in 1997 and has been developed through three successive phases.
The objective of this paper is to present the learning and the challenges from operating the largest offshore high pressure water alternating hydrocarbon gas injection (HC-WAG) pilot, with injection capacity of approximately 100 mmscf of gas injection per day in the giant Al-Shaheen field offshore Qatar. The paper also aims to share the methodology for analyzing the current HC-WAG pilot and optimizing the future development scenarios for extending the HC-WAG to the field scale.
Al-Shaheen field, offshore Qatar, is a giant complex carbonate oil field characterized by thin oil column, low permeability, and large lateral variations in fluid properties, see Reference [
Although WAG has been around for some time, the industry focus has been mainly on miscible WAG, and the vast majority of these WAG fields have been onshore, see references [
This paper summarizes the learning from evaluation of production and optimization strategy of the HC-WAG pilot based on various parameters related to operating such a pilot. The main evaluation parameters included are GOR constraints, WAG cycle lengths, composition of injected gas and the overall length of the project with regards to project economics. We will show that optimizing HC-WAG operations results in significant benefit for operating an offshore immiscible HC-WAG. The benefits are quantified in terms of incremental oil recovery & managed GOR from an optimized HC-WAG versus an un-optimized HC-WAG. The paper quantifies the impact of incremental oil based on WAG cycle length, the total WAG project duration, the WAG ratio, the total injectant slug size, tapering of the WAG cycle and injected gas composition. This paper is the first attempt to present the learning and challenges from one of the largest offshore high pressure HC-WAG pilot, currently being carried out in Al-Shaheen Field offshore Qatar, which has never been presented previously to the best of author's knowledge.
The paper is divided into two parts, first part of the paper details the on-going WAG pilot and its background and the details of the lesson learnt from operating current WAG patterns. Second part details the strategy for optimizing future WAG developments in the field for full field WAG implementation.
The Barzan Onshore Project is being developed by Barzan Gas Company Limited, a joint venture between Qatar Petroleum and ExxonMobil Barzan Limited, with RasGas Company Limited (RasGas) assigned to develop and operate the facilities upon completion. The engineering, procurement, and construction (EPC) work is being carried out by JGC as the primary contractor. JGC has subcontracted the construction execution of the work to eight major subcontractors. The project achieved 131 million man-hours without a lost-time incident from July 2012 to March 2014. The workforce peaked at more than 29,000 (or approximately 30,000) persons from multiple countries.
In February 2016 and in response to the difficult market conditions that had beset the oil and gas industry, Dolphin Energy launched The CORE Project - a long term cost optimization program. Standing for Cultural Change, Optimizing Productivity, Resourcefulness and Efficient Expenditure (C.O.R.E), the Project was designed to generate significant cost savings and enhance a culture of cost consciousness. This paper outlines how the Project was implemented through the direct involvement of Dolphin Energy employees, who were tasked with providing ideas and suggestions that would help optimize costs and drive significant efficiency improvements to achieve long term, sustainable results. Methods, Procedures & Process: To drive efforts across the company and ensure long term commitment, a collaborative'bottom up' approach was created. Twenty nine Division/Department Champions were appointed in Qatar and the UAE while a governance structure was put in place, monitored by a Steering Committee and chaired by the General Manager - Qatar. The project is managed through three main phases: 1. Generating cost optimization ideas through meetings and workshops across all departments.
