Abstract It is estimated that only 5% of Alberta's CBM reserves are recoverable (Rieb, 2006). A variety of techniques such as horizontal drilling and new fracturing methods have allowed greater recoveries of the methane gas. Alberta Innovates - Technology Futures (formerly the Alberta Research ...
Abstract Currently there are many smaller operators drilling on the Norwegian continental shelf. It is not an optimal use of resources to staff a complete drilling department in-house in all of these companies. For others, the drilling activity requires that wells are drilled in a discontinuous manner. ...
Abstract Recent interest in Chile to develop renewable energy sources has created a new market for drilling contractors with geothermal well experience. The geothermal fields in Chile are unique in that they combine the issues of remote area drilling with additional challenges such as desert conditions, ...
Abstract The purpose of this paper is to document Shell's experiences and learnings in the effort to better track and reduce Green House Gases (GHG) and improve Energy Efficiency in our downstream manufacturing and upstream production operations. The paper is based on Case Studies from various ...
Abstract Water production from hydrocarbon reservoirs is a serious problem in the oil industry. High water cut reduces the economic life of producing wells and costs the industry billions of dollars each year (Curtice and Dalrymple 2004). Throughout the years, several techniques and chemicals have been ...
Abstract In offshore operations where seawater is commonly used to prepare hydrochloric acid, calcium sulfate precipitation, the potential of which can greatly reduce the effectiveness of these treatments. This is because high concentration of calcium produced in spent acid mixed with high level of ...
Abstract Gravel packing, being one of the most reliable and robust downhole sand control techniques, is often the preferred method for establishing sand control. In reservoirs where the pressure has fallen below the water gradient, gravel placement using water based fluid will produce a high overbalance ...
Abstract Water production can reduce or block oil and gas production rates. In addition, the lifting, handling, and disposal of produced water negatively impact the hydrocarbon production economics. Among several techniques for water control, crosslinked polymer systems are the most effective for certain ...
Abstract Ormen Lange is the second-largest gas field in Norway, currently providing 20% of the domestic gas consumption for the UK. As one of the world's largest subsea big-bore gas wells - with production rates up to 350 MMscf/d per well, a 120-km tieback to shore, subzero seabed temperatures and a ...
Abstract Fracturing water-sensitive shale formations with water-based fracturing fluids requires special attention to minimize the destabilization of high-clay-content shale formations. The reaction of water with clay minerals can result in clay swelling, dispersion, and flocculation. Failure to prevent ...
Abstract The development of a sour gas reservoir (7000 ppm H2S and 20-25% CO2) in the Kujung fractured-limestone formation in the Gundih Field, Java, Indonesia faced challenges related to drilling operations that are prone to kick - loss cycles. Well control incidents were experienced on previous wells ...
Abstract Ecosystem based management is today the foundation of international regulatory frameworks for managing the oceans and seas. The approach enables sustainable use of marine goods and services while maintaining good environmental status and preventing subsequent deterioration. However we lack ...
Abstract A new biodegradable member of the chelating family of breaker fluids has been developed for treating oil and gas wells over a wide temperature range in environmentally sensitive locations. The enhanced filter-cake breaker is engineered to achieve improved bio-degradation with reduced toxicity ...
Abstract This paper shares an overview of how OMV was able to achieve environmental excellence in Pakistan in a remote, rural, socio-economically deprived environment. OMV Pakistan operates in a challenging environment in the Sukkur and Khairpur districts of the province of Sindh. Major issues facing ...
Abstract Chemical interactions between CO2/brine/rock can cause formation damage during CO2 injection. These interactions can affect injectivity during EOR operations, as well as affect storage capacity and seal integrity, which are primary concerns during CO2 sequestration. These interactions and the ...
Abstract Petroleum exploration and production (E&P) operations are inherently hazardous and dictate the need for prudent approaches to job planning and execution. Contractors are used extensively to support drilling, construction, and production activities and diligence should be exercised in their ...
Abstract Acrolein (2-propenal) is a highly effective microbiocide and sulfide scavenger that has been commercially available since 1960 and has been widely used in the oil and gas production industry. Acrolein is a liquid product supplied in and applied from specialized containers, eliminating potential ...
Abstract Through technological advances and due to the rising price of oil and gas, the oil and gas industry has been able to explore and extract in areas deemed too difficult just a decade ago. The risks facing companies over the next 10 years are no longer technical, and chief executives do not stay ...
Abstract The aerial extent of the Haynesville Shale play has been analyzed with regard to regulatory and permitting processes such that unavoidable surface impacts can be planned in a manner that allows operators to minimize both risk and cost from operations in environmentally sensitive areas - the ...
Abstract Exploration, drilling and production of shale gas plays such as the Barnett, Marcellus, Fayetteville, and Haynesville have transformed the unconventional gas industry. These and other existing and developing plays have had significant positive economic impacts to many regions, created tens ...
