Shallow Seas

Oil drilling and extraction platforms are currently being used in many offshore areas around the world. Whilst those operating in shallow seas are secured to the seabed, for deeper water operations, Dynamic Positioning (DP) is essential for the platforms to maintain their position within a safe zone. Operating DP requires intelligent and reliable control systems. Nearly all DP accidents have been caused by a combination of technical and human failures; however, according to the International Marine Contractors Association (IMCA) DP Incidents Analysis, DP control and thruster system failures have been the leading causes of incidents over the last ten years. This paper will investigate potential operational improvements for DP system accuracy by adding a Predictive Neural Network (PNN) control algorithm in the thruster allocation along with a nonlinear Proportional Integral derivative (PID) motion control system. A DP system’s performance on a drilling platform in oil and gas deep-water fields and subject to real weather conditions is simulated with these advanced control methods. The techniques are developed for enhancing the safety and reliability of DP operations to improve the positioning accuracy, which may allow faster response to a critical situation during DP drilling operations. The semisubmersible drilling platform’s simulation results using the PNN strategy show improved control of the platform’s positioning.

Abstract The critical role of effective inventory control has been much emphasized in the oil and gas industry which is subdivided into upstream and downstream sectors with drilling activities falling within the upstream subsector. In light of this development, this study investigates effective inventory control and effective drilling activities of oil and gas drilling firms as well as its relationship with revenue generating capabilities of oil drilling firms in Nigeria. Simple random sampling technique was adopted. Presentation and analyses of primary data collected with questionnaire and testing of the hypotheses were done using percentage and Spearman’s Rank correlation coefficient. The results from the tests with the use SPSS show positive and significant correlation between ineffective inventory management and downtime in the operations of oil and gas drilling with a correlation value of 0.682 with p-value = 0.001< 0.05 which implies that there is 68% relationship between ineffective management and downtime drilling.  There is a significant correlation between incessant downtime in operations of oil and gas drilling firms and their income level owing to poorly managed inventory control with a correlation coefficient value of 0.788 with p-value = 0.000< 0.05 which implies that there is 79% relationship between income (profit) level and downtime in drilling operations. Incessant downtime in drilling operations of oil and gas firms as a result of poor inventory control management has significant difference with termination of contract of oil drilling firms with the result the F-cal value as 344.632 while F tabulated value as 3.901 leading to rejection of hull hypothesis.  Based on the findings, it was the recommended that oil drilling firms should strengthen their inventory management system for effective and timely work delivery in order to avert downtime, loss of income and termination of contracts. Finally, members of staff of an oil and gas drilling firms in inventory unit should be trained and retrained on regular basis to embrace technological changes in inventory management to improve their performances which would in turn strengthen the inventory management of such firms.

Increasing Demand

With increasing demand for oil, drilling operations are soon going to start in the North Barents Sea. This area experiences iceberg occurrences. A systematic mapping of iceberg needs to be done to keep a tab on the iceberg location. Also, a study is required to assess the loads that come on to the mooring system in case of an iceberg – floater interaction. Therefore, this paper seeks to create a systematic mapping procedure for the occurrence of icebergs in the North Barents Sea using MATLAB. Further, from information on iceberg attributes and drift speed, the paper computes the iceberg mass and energy to define a probability density function of encountering an iceberg of a particular size. A scenario of an iceberg-floater interaction has been studied for different contact area geometries based on the kinetic energy model. Forces that develop on the mooring lines of a floater have been computed to aid in the designing of the mooring system of structures operating in the region fraught with the dangers of floating icebergs like the North Barents Sea.

The oil drilling operations large quantities of contaminted water known as "produced water" .   The present study aims to treatment of produced water of the North Rumaila and Zubair oil fields,using stainless steel autoclave. A series of experiments were carried out at different conditions,temperature, pressure, acidity, revolution per minute (RPM) and salinity with and without flocculation.The result showed that 93% of oil was removed. An improvement was conducted when usingsurfactants.
