This paper provides the results of lithostratigraphy and depositional environment of the uppermost Silurian

through Lower Devonian Winduck Interval section from three areas widely distributed in the central Bancannia

Trough from Bancannia South 1 well, the southern Pondie Range Sub-basin from Pondie Range 1 well and the

northwestern part of the Blantyre Sub-basin from two wells, the Booligal Creek 1 and 2. These wells were studied

using wireline log, core and cutting data to predict sequence stratigraphic architecture and its implication for

hydrocarbon sandstone reservoir potential. This study necessitated the use of detailed facies prediction relationships

and geometry of lithostratigraphic concepts for the purpose of establishing a sequence stratigraphic

architecture framework of the studied areas. Two units were established, lower and upper Winduck Interval,

within the Winduck Interval identified by lithological data examination and wireline log characteristics of the

sediments from the four wells in the study area. Results of the lithology type analysis showed that the Winduck

Interval is interbedded richly in sandstone and siltstone complex deposits. This paper presents a clear picture of

the sequence stratigraphic model, as well as that of the three third-order depositional sequences (DS1, DS2 and

DS3, respectively) that are identified from changes in systems tracts patterns (composed of lowstand, transgressive

and highstand), vertical and lateral facies sequence thickness changes and the lithostratigraphic units

distribution in the Winduck Interval section. Potential reservoir prospectivity targets are identified in lowstand

system tracts and highstand system tracts deposits consisting of sandstone facies and thin silts, while the

transgressive system tracts deposits consist of shales and some interbedded shaly siltstones, many having

excellent potential source and seal properties. The contribution of sequence stratigraphy as an approach to

understanding lithostratigraphy of the Winduck Interval has important significance in regard to future hydrocarbon

reservoirs exploration across the central Darling Basin.

Factorial field experiment was conducted to evaluate relationship between two genotypes of local wheat (Triticum aestivum) and phosphorus soil test values. The M 0.5 NaHCO₃ based (Olsen phosphorus) extractant was carried out on soils taken from the plots. The experiment was conducted at western region of Libya. Soil pH at the experimental site was 8.1 and the texture is sandy. The experiment was performed using a randomized complete block design (RCBD) method with three replicates for each treatment of phosphate fertilizer at concentrations of 0, 60, and 120 kg P₂O₅ ha^-1 for both genotypes. Results were expressed by relative values (Relative Yield). Relative yield (RY) of the two wheat cultivars showed similar significant responses to both soil test values and the grain yield.  Linear relationship between relative yield and the grain yield at 0 kg P2O5 ha^-1 for both genotypes was found, whereas, non-linear relationship was noticed among treatments that received 120 kg P₂O₅ ha^-1. Both the linear and non- linear relationship have explained by tendency curves and showed how both genotypes response to phosphate fertilizer.

Correlation and sequence stratigraphic interpretation was conducted on the upper Lower through upper Middle

Devonian sandstones of the Snake Cave Interval succession between the southeast Blantyre and northwestern

Neckarboo sub-basins across the central Darling Basin. This article necessitated the definition and use of many

sedimentary lithotypes related to different facies associations and depositional environment criteria for the

purpose of establishing the sequence stratigraphy to aid hydrocarbon exploration of the studied areas. The data

set used a combination of wireline logs, core/cutting data and analysis of the paleo-environments of sedimentary

facies from three wells. The sedimentological analysis showed that the Snake Cave Interval section presents three

different facies associations, which are visible in both vertical and lateral successions, and are characterised as:

meandering and braided fluvial facies associations with minor fluvio-shallow lacustrine complex facies associations.

The Snake Cave Interval section in the studied areas is consistently defined by six third-order depositional

sequences informally named SCS1, SCS2, SCS3, SCS4, SCS5 and SCS6 in the Nyngynderry-1 and Mount Emu-1

exploration wells, and the Kewell East-1 stratigraphic well. All the stratal patterns in the internal sequence

stratigraphic units are asymmetric and marked by lowstand, transgressive and highstand systems tracts separated

by sequence boundaries, maximum flooding surfaces and transgression surfaces with unique gamma-ray log

response characteristics calibrated by particular lithologic aspects. These are all incorporated within the

sequence stratigraphic approach to hydrocarbon reservoir prediction. The stratigraphic architecture of the thirdorder

depositional sequences presented here in our study has implications for the hydrocarbon potential of

sandstone reservoirs in the southeastern Darling Basin including the Snake Cave Interval succession targets.

A strengths, weaknesses, opportunities, and threats (SWOT) analysis has become a key tool used

by businesses for strategic planning. Scholars have conducted SWOT research for over six

decades. However, a collective understanding of SWOT analysis remains vague. This study

accessed, analyzed, and synthesized the SWOT literature, allowing for new theoretical

perspectives and frameworks to emerge. Using an integrative literature review, this study reviewed

SWOT studies historically, providing a greater understanding of the SWOT analysis in different

sectors and the different approaches used in SWOT studies. Furthermore, it fills the knowledge

gap in the strategic planning context and indicates meaningful implications for managers that could

help improve their strategic decisions.

Detailed sedimentological analysis of depositional facies through lithostratigraphic correlation was conducted for the upper

Lower Devonian through the upper Middle Devonian Snake Cave Interval strata of the southeast Darling Basin. The methodology

used includes identifying changes in rock types from sedimentary lithotypes within different facies associations from well

data, wireline-log patterns and palaeoenvironmental reconstruction. This has helped to define a lithostratigraphic correlation for

the Snake Cave Interval section. This study has re-interpreted the upper and lower boundaries of the Snake Cave Interval using

marked changes in gamma-ray log features and core and cutting lithology logs to estimate the depth of these boundaries from

three wells. The Snake Cave Interval consists of ten lithotypes that define three facies associations (FAs) in the three available

wells. These were deposited within three main facies associations: meandering fluvial facies association A (MFFA-A), braided

fluvial facies association B (BFFA-B) and fluvio-shallow lacustrine complex facies association C (FSLCFA-C). The paper

includes a broad description of the significance of lithostratigraphic facies related to depositional environments of the upper

Lower Devonian through the upper middle Devonian succession section.

Factorial field experiment was done to estimate agronomic phosphorus use efficiency (APE) and partial factor productivity (PFP). The experiment was run in a private farm in Janzour area which is located west of Tripoli Libya in 2018. Two localized wheat genotypes (L1, and L2) and three rates of triple super phosphate fertilizer (0, 60, and 120) kg P2O5 ha-1 were used. The results indicated that both genotypes have good response to phosphate fertilization. APE and PFP achieved positive relationship with only 60 kg P2O5 ha-1 rate for both genotypes. Moreover, APE calculation showed positive relationship with increasing soil phosphorus test values, meanwhile, APE values was kept steady at 120 kg P2O5 ha-1 .

This paper is focused on the detailed lithostratigraphic facies characterisation of the paleo-environments

of the uppermost Silurian through Lower Devonian Winduck Interval strata from the

Bancannia South 1, Pondie Range 1 and Booligal Creek 1 and 2 wells, across the central Darling

Basin of western New South Wales. Based on data from both wireline logs and drill cores and cuttings,

an interpretation of paleo-environments and evolution of the depositional facies is presented.

Our approach involves two key interpretations. The first outcome was the delineation of

the Winduck Interval section (maximum observed thickness of approximately 1475m) and formal

subdivision into lower and upper Winduck Intervals, based on well data from the central

Bancannia Trough, southern Pondie Range Sub-basin and northwestern flank of the Blantyre Subbasin.

The second outcome is based on the internal lithostratigraphy of the Winduck Interval represented

by 11 sedimentary lithofacies organised into three lithofacies associations (LFAs). LFA-X1

is interpreted as distributary-channel sandstone complex deposits, LFA-X2 is interpreted as

distributary mouth bar with small-scale braided delta plain complex deposits and LFA-X3 is interpreted

as tidal channel sands with proximal delta front complex deposits. Subsurface lithostratigraphic

facies analysis relationships and depositional environments of the Winduck Interval section

have implications for evaluating the hydrocarbon potential and may assist future exploration

efforts in the central Darling Basin, especially the Bancannia Trough and Pondie Range Sub-basin.
