Development of a Pore Pressure and Fracture Pressure Gradient Prediction Model for few exploration blocks in Mannar and Cauvery Basins, offshore Sri Lanka

Jayasinghe, JMSTW; Kurukulasuriya, AC; Jayasinghe, WMTU; Wickrama, MADMG; Senadhira, AMADM; Ratnayake, NP [Conference-Full-text]

Availability of a pore pressure and fracture pressure gradient prediction model for petroleum well drilling is a basis for safety, cost effectiveness and the efficiency of the overall drilling program. Petrophysical data ...
Development of an Algorithm for Optimum Allocation of Multiple Teams to Borehole Drilling Sites

Dilanthi, UN; Fernando, JMMP; Dissanayake, DMDOK [Conference-Full-text]

This research focuses on the allocation of teams to complete a set of time duration predefined borehole investigation jobs. An algorithm was developed, to output which team does which jobs and when. Initially, filtering ...
Dynamic Model to Forecast Slope Stability A Case Study: Geradiella Lanslide Site

Abeygunasekara, WAHA; Hewavidana, SM; Jananthan, T; Madawala, RMS; Vaheeshan, K; Premasiri, HMR; Abeysinghe, AMKB; Weerawarnakula, S [Conference-Full-text]

Forecasting the potential for disastrous events such as landslides has become one of the major necessities in the current world. Most of the landslides occurring in Sri Lanka are found to be triggered by intense rainfall ...
Effects of Recycled Fine Aggregate Content on Cementitious Mortar

Subasinghe, IS; Madusanka, VPS; Jayasinghe, VRDK; Sundarapperuma, SMAP; Fernando, WSSR; Chandrasiriand, SAKN; Karunarathne, S [Conference-Full-text]

Properties of the recycled fine aggregates and the suitability of the same in cementitious mortar were studied and compared with those of natural fine aggregates. The results showed that the particle size distribution of ...

Integrated Remote Sensing and GIS Approach for Demarcation of Groundwater Potential Zones in Ambalantota Divisional Secretariat

Mayadunna, BB; Weerasekera, WL; Senanayake, IP; Dissanayake, DMDOK [Conference-Full-text]

Demand for water in Hambantota district is increasing rapidly due to agricultural activities, massive on-going development projects, industrialization and consequent population growth. Implementation of a proper water ...
Investigation into off-the-road tire performance at Aruwakkalu Quarry

Walpita, S; Priyankara, I; Wickrama, M; Jayawardena, C [Conference-Full-text]

The performance of heavy mobile equipment used in the mining industry is often restricted by the capabilities of their tires. These off-the-road tires experience highly variable and complex working conditions in comparison ...
Parameters which affect the Flow Rate of Minerals through Silos with varying Silo angles and Particle Size

Kankanamge, LUM; Siriwardene, KM; Sairudeen, MI; Rangana, WGL; Chathurange, KJVM; Rohitha, LPS [Conference-Full-text]

The study was carried out to develop a model for mineral flow rate through conical silos. Dominant factors governing the flow behaviour of minerals through silos were studied. Silo angle and the outlet diameter were ...
Phlogopite Mica Mineralization in the Central Part of Sri Lanka and Identify Suitable Areas for Mining
