Executive SummaryAn educational visit was held to Land Rig T-201 which at that point in time was situated near BSP HQ. The main focus of this visit was for further education on land rig layout and the equipment as well as the safety procedures of the drilling site. For this report, only some equipment are explained and there were no pictures that we could take. A draft of the rig layout have been made by our group, Alpha Synergy.

1 IntroductionLand Rig T-201 which is owned by KCA Deutag and utilizes mast for fast assembly as well disassembly has been operating in Brunei since 1950 under the contract of Brunei Shell Petroleum. It was awarded with Best Fleet award by Shell worldwide within the last few years. During the time of visit, T-201 was doing its second last operation in Brunei before being deported and it was doing a well abandonment operation.1.1 Site Visit DetailsName:Rig T-201

1.2 Site LayoutRefer to Appendix A1.3 Visits ObjectiveThe Objective of the visit was to: Experience firsthand the safety on rig Familiarize students with real rig layout and equipment Enhance knowledge on rig safety, layout, system and equipment.2 Visit Description The visit commenced with assembling at the security post where all individual were told to sign in for personnel accountability and were instructed to leave electronic items along with any accessory worn outside the rig area. This is followed by a safety briefing by the operation manager and a descriptive tour divided into 4 separate groups of the entire rig area.2.1 HSE BriefingPost signing in, all individuals were directed to a meeting room where Safety briefing was conducted by the HSE officer describing the:i. Importance of signing and signing out for personnel accountabilityii. Primary Muster Point Locationiii. Secondary Muster Point Locationiv. The 2 different alarm sounds which are followed by announcementa. Fire Alarm (2 short and 2 long blasts)b. Abandon Location/ gas alarm (continuous blast with the rig horn)v. Stop Work Procedurevi.

The containers were filled with quite a few items however, only some were highlighted.StoreHighlighted Items

1Paint, Pressure gauge, Fall arrester equipment and others

2Used Slings and Shackles with tag system for monitoring engraving on slings and shackles just in case tag is lost

3Mud Pumps, Relief valve

4New Slings and shackles with tag and engraving

Table 1. Items mentioned during tour2.2.2 Open Storage AreaChemicals were stored at this area with protection underneath just in case of leaking. Other than that, a few mud tanks for used muds were placed at this open storage area. At the side of this open storage area, the waste bin for waste segregation are placed. The secondary muster point is also located at the entry.2.2.3 Drill Pipe RackThe pipes were stored on racks in the forms of doubles due to the space constriction. 4 drill pipes were used. Estimated length for 1 stand of the drill pipes are approximately 27 meter.

2.2.4 Mud Circulation SystemEffective solids control can be attributed to the overall performance of all the components of the mud systems. Conditioning the drilling fluid with the goal of dramatically lowering maintenance cost, avoiding excessive chemical treatment and maintaining mud systems volume will decrease the chance of equipment failure, unnecessary high mud costs, hole and drilling problems.EquipmentFunctionDiagram

Mud PumpEmsco FB-1600Triplex Mud Pump Each driven by two GE-752 traction motors 5000 psi Fully Refurbished American Made

Function:To pump the drilling fluid into the mud circulating system

Shale Shaker 3 Pc BrandtVSM 300

.Shale shaker is the first-phase main solids control equipment in drilling fluid processing system. It is mainly used for removing large solids from the drilling fluid through vibrating the solids when the drilling fluid flows to the screen of the product

Poor Boy DegasserOilfield drilling Poor boy degasser that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. No flaring was done for T-201

2.2.5 Rig Floor2.2.5.1 Operators UnitDrillers control unit where the brakes are being managed. There are the main brake that uses the paddle as well as the auxiliary brake. Other than that, there were: Video Monitoring system Live feed system to the HQ for the general information such as total depth

2.2.5.2 Hydraulic Power UnitUsed to power the whole hydraulic system.2.2.5.3 Draw worksThe main break system for the rig2.2.5.4 Iron RoughneckEquipment for making and breaking of 2.2.5.5 Derrickman Escape LineLine extending from the Mast to the ground so that the derrickman can escape in case of emergency. This line is tested with a 70kg doll prior to usage to avoid any injury.2.2.6 Power SystemThere were 3 generators used in order to support the rig operation. These engines were not used to the full extend to avoid overload.

3 Drilling Plans Delay Limited Operating Area Shifting of rig from original plan tilted Less stair (limited entrance/exit path) Stair to rig floor placed on pipe and small metal stool Drill Pipe stacked in doubles instead of in stands Parts of Mast broken Near civilian area Complain on truck passageway caused change in layout Noise complain Faulty saver sub due to inconsistency in thread Incompatible iron roughneck

4 Reflection / ObservationIt was a very interesting and informative visit that really helps better understanding of the safety on rig as well as the equipment. Visualization of equipment could also be done due to this visit. Other than that, being around the rig for half a day gave a sense of feeling as to how it would be as a well engineer on site.APPENDIX A RIG LAYOUT
