Clustering Problems in Offshore Drilling of Crude Oil Wells

Budi Utomo, in this paper explain that offshore drilling carried out to obtain crude oil through the oil wells. The means that must exist in the operation of offshore drilling is a bridge structure (plate form) as a place to put the drilling equipment. Known two kinds of platforms, that is platforms permanent (fixed) which stands on the feet of reinforced concrete, and the bridge is not fixed like swamp barges, drilling ship (floaters) and jack-up rig. Jack up rig is one of the offshore rigs that have the ability to elevation in accordance with a sea depth of drilling. Drilling equipment is a range of equipment that is prepared in such a way, so that such a drill rod, and all this equipment has a hole inside that allows for fluid or mud circulation.

Gas Lift

Abstract Laboratory and field tests are reported for titanium parts for gas lift valves and down-hole oil well pumps. While titanium performed well in the laboratory tests using aerated fluids, and did well in field tests of gas lift wells, similar trials in wells pumping sour crude oil well showed titanium to be inferior to normally used materials. Authors conclude titanium is suitable for use in gas lift valves and could be competitive to presently used materials at a lower price. They conclude titanium is not suitable for use in oil well pumps, but might perform better if hardened. It also is at a competitive disadvantage to commonly used materials costwise. While titanium is cathodic to materials commonly used in oil wells, no marked corrosion was attributed to this property after exposure of coupon sets in a producing well. Titanium was found resistant to abrasion by sand-laden aerated oil well fluids in laboratory tests. 6.3.15, 8.4.3

Atomic Absorption Spectrometric

Crude oil samples from four oil wells in Nigeria were analyzed for the following seven trace elements: V, Cr, Mn, Fe, Co, Ni and Pb using Atomic Absorption Spectrometric (AAS) analytical technique. The mean concentrations of these elements on a weight to weight basis were found to range from 0.017 ± 0.005 to 1.977 ± 0.397ppm. The results also show that V was the most abundant metal with Ovia 1 Long String (OLS) Oil well containing the highest concentration of V. The V/Ni ratio from the method used shows that Ovia 1 Long String (OLS) and Ovia 1 Short String (OSS) were the most and the least matured oil wells respectively. All the samples had comparably the same V/Ni ratio (1.16—1.77) implying identical source for all the oils. Furthermore, the calculated values of American Petroleum Institute (°API) gravity determined using the measurement of specific gravity (S.G.) of the crude oil samples range from 47.80 to 55.50. This suggests that the samples fall into one category of crude oil classification which in this case is light crude.
