Abstract

Buton island as a potential area for conventional oil and gas, as well as asphalt/bitumen has long been the target of evaluation aimed at exploiting this potential, although to date no economic exploitation has been implemented. In this study, the potential of Buton asphalt/bitumen with mineable and in situ (non-mineable) status was studied and evaluated. In this study, qualitative and quantitative analysis have been carried out from Landsat 8 and Shuttle Radar Topography Mission (SRTM) data with the aim of identifying the presence of active faults and gravity due to orogenic processes. The lineament density pattern shows a general direction of NE-SW to NNW-SSE. The lineament process between satellite image data and gravity surveys helps efforts to identify the distribution of asphalt on Buton Island. Through combining distribution patterns of the Sampolakosa, Tondo, and Winto Formations, contain asphalt/bitumen, the study produces distribution of asphalt/bitumen accumulation in the region, both in surface/mineable and in situ categories. The 'best estimate' reserves obtained are 786.6 million barrels and 46 million barrels, respectively for asphalt/bitumen surface/mineable reserves and in situ/non-mineable reserves. It is hoped that this information regarding the potential/reserves of asphalt/bitumen on Buton Island may support efforts to exploit it

Abstract

Laboratory and field studies indicate that almostevery operation in the field, such as drilling, completion,workover, production and stimulation are potential sourceof damage to well productivity. Formation damage haslong been recognized as a source of serious productivityreduction in many oil and gas reservoirs. The mud cakeis a damage that occurs in formation caused by drillingprocess. Prevention of formation damage has the fol-lowing advantages: a) To reduce ultimate comple-tion costs; b) To preserve barriers; c) To improvesweep efficiency.

Abstract

Sand quality laboratory tests have been carried out on local and import uncoatedsands. Based on results of sand sieve, roundness, sphericity, turbidity, acid solubility andcrush resistance at 3000 psi quality tests of import uncoated sand has better quality thanlocal sand. The import sand fulfills API - RP 56 specification requirements and -will be ableused in hydraulic fracturing operation. Whereas, the local uncoated sand does not achieveAPI - RP 56 specification requirements
