Physical characteristics and aquatic settlement properties of offshore drill-cuttings.
… points were observed: the required input data on cuttings characteristics was not available for specific drilling conditions, and; the settling properties of the particles was not adapted to the type of modelled particles. There was no readily available information about correlations between the …

X-Ray Fluorescence Analysis of Tuscaloosa Marine Shale Cuttings from Horizontally Drilled Wells
… for this study were geophysical logs and well cuttings from two lateral wells (B-NEZ 43H 001 and B-NEZ 43H 002) from Little Silver Creek Field, Tangipahoa County, Louisiana. Resistivity and total gamma are the geophysical properties that were available for this study. X-ray fluorescence (XRF), …

Sustainable treatment of oil contaminated waste: oil-based mud (OBM) drill cuttings and soil.
… hydrocarbons in oil based mud (OBM) drill cuttings and soil. Soil washing using biosurfactant is one of such technological developments. Biosurfactants are surface active compounds produced from biological origin. They are amphiphilic molecules, consisting of hydrophilic and hydrophobic …

Propagation of wild-collected Prunus americana Marsh. by rooted cuttings for germplasm conservation in the Southern Appalachians
… for a viable rooted stem-cutting method. Cuttings were collected from trees in eight locations in May, July, and September, treated with 0-ppm, 1000-ppm, 3000-ppm, or 8000-ppm IBA for five seconds, and held in a mist propagation bed with basal heat for four to six weeks. The results of …

An Assessment on the Cultivation of Black Cottonwood Cuttings in Nootka Lupine Fields in Conjunction with Site Preparation
… in South Iceland in which the planting of cuttings from two black cottonwood clones were prepared using three mechanical methods in addition to an undisturbed control plot. The first year results are reported here. Site preparation was effective in increasing survival and growth of planted …

Development of an optimised integrated underbalanced drilling strategy for cuttings transport in gas-liquid flow through wellbore annuli.
… which affect the wellbore hydraulics and cuttings transport efficiency during UBD operations. Thus, this study developed a rigorous integrated strategy for maximising the efficiency of UBD for the transport of cuttings in gas-liquid two-phase flow through wellbore annuli. An experimental …

Effects of cultivar, leaf position, and stem tissue on growth of single-leaf cuttings of Ipomoea Batatas Lam
Sweet potato single-leaf cuttings of cultivars ‘Centennial,’ ‘Jewel,’ and ‘Nemagold’ were planted in plastic pots containing steam-sterilized sand. Fully opened leaves were counted from the terminal apex on stock plant stems, and leaf positions 1 to 3 and 7 to 9 were referred to as mean leaf …

Cuttings transport and hydraulics optimisation for underbalanced drilling (UBD) operations in concentric and eccentric, directional and extended reach wells.
… increased tendency for the settling of drilled cuttings in the wellbore. An accurate prediction of fluid dynamics and cutting transport efficiency is required to achieve an effective pressure-management hole-cleaning operation. In this research, a theoretical, numerical and experimental study …

Soilless media for seed germination and growth of tomato transplants, and for the rooting of certain herbaceous stem cuttings
… Chrysanthemum morifolium cv Sunny Mandalay stem cuttings were rooted in six media. These media were composed of various proportions and combinations of sand, peat moss, Weblite, and perlite. Their root system and foliage condition were evaluated 18 days later. Weblite was significantly better in …

Propagation of Cupressus lusitanica by cuttings: A thesis submitted in partial fulfilment of the requirements for the National Diploma in Horticulture (Hons.) of the Royal New Zealand Institute of Horticulture
… to study the propagation of Cupressus lusitanica cuttings. Hardwood, softwood and half-ripe cuttings were used in Experiments 1-3 respectively. The cuttings were placed in a polythene tent and under mist, with and without bottom heat. Bottom heat appeared to be necessary and polythene tent …

The Histology and Histochemistry of The Wound-Healing Process in Geranium Cuttings in Relationship to Basal Stem Rot Caused by Pythium Ultimum
Geraniums are largely propagated by cuttings even though new seed strains are now becoming popular. They are available as unrooted, callused redi-root (adventitious root initials just beginning to emerge) or fully rooted cuttings. Blackleg, caused by Pythium species, is a problem in geranium …

Feasibility of sustainable recycling of drill cutting as additive in flexible base
The management of drill cuttings, a byproduct of oil and gas drilling, presents significant environmental challenges. In Texas, millions of cubic yards of drill cuttings have accumulated, raising concerns over long-term storage and disposal. At the same time, the state consumes approximately 3.7 …

Propagation, height control, and flowering of Hypoestes phyllostachya
… growth but did not enhance germination. Stem cuttings did not require bottom heat or rooting hormone to induce adequate adventitious root formation. Three-node cuttings rooted more rapidly and had a more extensive root system than two-node cuttings. Cuttings stuck at a density of 200 per flat …
