Sand control method employing special hydraulic fracturing technique

Abstract: A novel sand control method is disclosed wherein high viscosity, high sand concentration, fracturing fluids are pumped through sets of vertically oriented perforations in borehole casings located in unconsolidated or loosely consolidated pay zones. Various techniques are utilized to insure that sand fills disposed on either side of the borehole casing cover and substantially overlap each borehole casing perforation set. Procedures are then followed to bring the well into production without washing out the sand fills in these areas, whereby the resulting perforation-sand fill configurations effectively control sand production from the treated zone.

Catalytic cracking of hydrocarbons

Abstract: Emission of noxious nitrogen oxides with the flue gas from the regenerator of a fluid catalytic cracking plant are reduced by incorporating into the circulating inventory of cracking catalyst separate additive particles that contain a copper-loaded zeolite. A particularly effective additive is provided, for example, by treating a ZSM-5 zeolite in a matrix consisting predominantly of titania, zirconia or a mixture thereof with a solution containing both copper and rare earth cations to incorporate both of these elements with the zeolitic composition.

Palaeogene magmatism in the Faeroe–Shetland Basin: influences on uplift history and sedimentation

Abstract: Palaeogene sedimentary basin development along the NE Atlantic margin was strongly influenced by a major period of magmatism associated with the initiation of ocean-floor spreading between NW Europe and East Greenland. Five elements to the magmatism in the Faeroe–Shetland Basin can be identified and related to the Palaeogene depositional sequences: extensive lava fields and lavas from central complexes (the Erlend Complex for example) erupted into subaerial and marginal marine environments and consequently influenced sediment distribution within the basin; dyke swarms, which constitute the feeder system to the lava fields; sill complexes, possibly related to the fissure systems, which affect reservoir quality on a local scale; central igneous complexes overlying magma chambers which controlled clastic sedimentation patterns (Westray for example); tuffs (for example the Balder Formation and Kettla Member) which aid correlation of reservoirs and seals. The main development of Paleocene sandstone reservoirs along the axis of the Faeroe–Shetland Basin appears to have been synchronous with the phases of thermal uplift along the basin margin and pulsed volcanism at c. 62 Ma, 58 Ma and 56.6–55 Ma. The major episodes of reservoir deposition may reflect the activity of the Iceland plume and provide independent evidence of the pulsed nature of the magmatism. This model integrates igneous, sedimentary and tectonic data with precise radiogenic ages and biostratigraphy. It allows detailed correlation of reservoirs and seals within the Paleocene play fairway and improves prediction of stratigraphic trapping styles common in this play.

Catalytic Hydrodemetallation of Petroleum

Abstract: Publisher Summary This chapter discusses the elements of physical chemistry, heterogeneous catalysis, and reaction engineering that are necessary for a basic understanding of catalytic hydrodemetallation. It focuses on vanadium and nickel removal because these are the most abundant metals in petroleum. Following this, it discusses the nature of the metal compounds in petroleum oils and the targeted reactants. The chemical composition of the host petroleum and residuum is described, including a discussion of the two classes of metal compounds: (1) metalloporphyrins and (2) nonporphyrin metals. A comparison between the characteristics of vanadium and nickel complexes and their distribution in residua is also presented. Commercial residuum hydroprocessing technology is then discussed to establish the role and requirements of hydroprocessing in the overall refinery residuum conversion scheme. Finally, the kinetics and mechanisms of catalytic HDM reactions are presented and future perspectives for the study of residuum hydroprocessing and the rational design of hydrodemetallation catalysts and processes are highlighted.
