Analysing the relationship between skin and formation damage of an oil well (time depended)

Ruwanpathirana, RS; Nagasinghe, RV; Welagedara, WWVP; Wickrama, MADMG; Senadhira, AMADM; Ratnayake, NP; Vijitha, AVP [Conference-Full-text]

The concept of skin and formation damage play a vital role in productivity of an oil well. The objective of this study is to introduce the effect of skin into the well flowing equation in transient state. The effect of ...
Cost reduction of quality controlling in metal quarrying

Basnayaka, LR; Samarathunga, SPGN; Susantha, TKJ; Nawaneethan, M; Wickrama, MADMG; Samaradiwakara, GVI; Dassanayake, ABN [Conference-Full-text]

Quality controlling of aggregates is a major concern in aggregate industry. Cost of quality controlling can be minimized via finding correlations between different test on aggregates and rocks. Los Angeles abrasion value ...

Wijesinghe, KADR; Hewavitharana, TD; Mahsoom, MSM; Wickrama, MADMG; Senadhira, AMADM; Ratnayake, NP [Conference-Full-text]

Due to high operational and financial risks associated with the investments in the petroleum industry, all precautions are taken by the operators to achieve a safe and cost effective well completion. Casing design of a ...
Developing a hydrogeological model for Aruwakkalu limestone mine, Puttalam

Dayarathna, EAC; Pethum, LLDI; Sunanda, DJ; Wedisinghe, WMCC; Dassanayake, ABN; Wickrama, MADMG [Conference-Full-text]

A hydrogeological model has been developed for the Aruwakkalu limestone mine to study the behaviour of groundwater flow, associate with specific problems within the mine, in this research. Groundwater flow model ...
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 ...
Exploration of ilmenite potential in and around Kalu and Benthara river mouths with special reference to the variation of TiO2 content along a selected strech of Kalu Ganga

Kumara, HANHM; Medagoda, CJ; Sivakala, S; Sugaraj, K; Wickrama, MADMG; Vijitha, AVP; Dissanayake, DMDOK; Rathnayake, NP [Conference-Full-text]

Although Ilmanite, Rutil, Zircon and Monazite occurs in beach sand of Sri Lanka, the sufficiently concentrated deposits for economic exploitation have been only identified yet in and around Pulmoddai, Baruwala and Kudremalai ...
