Who we are
Welcome to Bakken oil drilling. In the recent oil field boom our geologists have discovered a deposit of oil under the lake in evocity designated V2P in our survey. That has remained untapped.
We believe this well will hit 700 barrels of oil a day, so after buying the land we plan to erect a small derrick in this area and drill that black gold up.
History of the rig
The drilling rig you'll be working on is the Penumbra Venture Drilling Rig 28, recently she's been modified, after a major accident where the old superstructure caught fire, after a plane collision. with new and enhanced features, such as; a top drive drill, an overhauled, deck space, with adequately spaced utilities, including a large cargo crane, seperate flight deck, repositioned cabin space (serving as canteen, bunk, and toolpushers office, as well as med bay), dedicated pipe handling rack, enhanced latch up tongs, and mud shakers/mixers, as well as a modernised computerised drilling control house.
However this modernisation has come at a cost, so the crew has been cutback, with many people taking on duel roles and responsibility, don't worry you'll be compensated fully for this.
We will include images of the rig and various parts at a later date for y'all so you know what's what.
The rig
The Penumbra Venture is a fixed shallow water drilling platform, featuring, power assisted tongs, top drive electric drill, large capacity mud tanks, and trip tanks, blow out preventer, and a supply barge, with functioning crew space, it might not be the biggest or most comfortable rig out there, but she will look after you, the cabin space, features sleeping quarters, showers and toilets, galley/recreation room, and the OIM office, as well as a functioning medical centre. Coming equipped with a 3500 ton hoist crane, 1000 ton top drive drill, and functional helipad, as well as elevator access for the spider deck where in calm seas, you can fish on your down time.
The Job
There are many aspects to working on a rig and many jobs all of which will be explained in this article. In summary we will be preparing the oil rig for drilling, loading supplies from the barge, ensuring the BOP is correctly installed during lay down, tripping in the casing pipe, drilling that hole, and ensuring continuous good drilling progress, swapping out drill bits as necessary, and when we hit TD tripping out that drill and running in the well casing pipe, then you'll be stripping down the drill deck and installing the well pump connecting it to the casing pipe, and begin refining that oil. Sound like a lot of work? Sound hard? It is, but by hell it'll make a man out of you. On the rig you'll find various terms and roles you aren't familiar with, don't worry we'll include a glossary for you..
The following jobs are combined
Offshore Installation Manager and Toolpusher, due to the small rig size, and an OIM's extensive experience it makes sense to combine the two roles, with a smaller crew the OIM has more time to supervise operations directly and thus takes on this role.
Floorhand, Crane Operator, Motorman and Medic. With a smaller rig comes a smaller crew size and greater requirements from each individual. Each floorhand will require a specific skill in one of the three listed specialisations above.
Offshore Positions.
Rig heirarchy
Company Representative: (1/1) Sparx.
The representative of the oil company or operator on a drilling location. For land operations, the company man is responsible for operational issues on the location, including the safety and efficiency of the project. Even administrative managers are expected to respond to the direction of the company man when they are on the rigsite. Offshore, depending on the regulatory requirements, there may be an offshore installation manager, who supervises the company man on safety and vessel integrity issues, but not on operational issues.
It is not unheard of for the Company man, and the OIM to have differences of opinion at times, regarding operations and performance......
Offshore Installation Manager: (1/1) Eisenhorn
The OIM is the overall person responsible for the rig and its personnel. His/her position is equivalent to the Captain position on board a ship and he/she must take an extensive series of safety, environmental and leadership courses to build up the necessary theoretical knowledge to lead a crew of up to 180 members.
The OIM is also the overall responsible for all safety of personnel onboard, and he/she ensures that all operations onboard are performed in line with all rules and regulations. He/she also ensures that the client’s representative is kept informed about all activities and operations on board the rig.
Further to this he has the authority to NRB any crew member he deems to be unsafe, or otherwise damaging to the rig/crew and production.
Toolpusher: (1/1) Eisenhorn
The Senior Toolpusher is the overall responsible for the Drilling Section of the rig and reports directly to the OIM. The Senior Toolpusher is the primary drilling specialist on board and therefore supervises all drilling operations from start to finish; utilizes available real-time data to deliver manpower to specific equipment and complete the operation.
He/she is also responsible for the overall installation, maintenance, testing and connection/disconnection of the Blow-out prevention (BOP) equipment and installation of casings; and the proper training, appraisal and overall leadership of the drilling personnel.
Driller: (1/1) Mason Estell
The Driller is responsible for supervising and carrying out the drilling and well control and other work in connection with the drilling operations. He/she must ensure a safe operation of the drilling control system; drawworks; pipe handling systems; mud circulating systems; and Blow-out prevention (BOP) equipment in accordance with the requirements specified in the operating procedures.
Assistant Driller: (1/1) Jake Turner
The Assistant Driller supervises the work done on the drill floor and all other work in connection with the drilling operations. The Assistant Driller position is regarded as a trainee position to achieve competency to work as a Driller.
Assistant drillers train roughnecks to recognise abnormal well conditions in order to prevent leaks and rig blowouts. Abnormal well conditions can include excess pressure, a reduction of the weight of the drillpipe, sedimentary deposits mixed with the oil, or changes in drilling weight. According to Transocean, assistant drillers make regular reports to a senior drilling supervisor in order to detail well conditions. As well as conducting pre operation safety equipment checks.
Drilling Fluid Operator/Derrickman: (0/1)
The DFO supervises and inspects the mud processing areas and ensures that these are kept clean and tidy, and that maintenance on the equipment is carried out in accordance with procedures. The DFO pays special attention to the valves and pumps in the mud and cementing systems.
This job is also to stack the pipe, latch the pipe, and ensure the drilling mud is kept to an appropriate level. Working at over 90ft in the air, and riding the drill to reach his work station, taking out pipe from the derrick stack and positioning it in the drill, he has the life and death of the work force in his hands.
Roughneck/Floorhand: (0/3)
The Floorhand is responsible for pipe handling, casing and drilling equipment on the drill floor as well as carrying out maintenance on the equipment.
The Floorhand also makes and breaks rotary connections using rig tongs, handles tubular goods, elevators and slips, and operates semi-automated pipe-handling machines. Additionally, the Floorhand participates in the daily cleaning, housekeeping and maintenance work on the drill floor and in the shale shaker room. As well as doping all pipe before connection.
[spoiler=combined roles description Floorhand]
Motorman: (0/1)
The man in charge of maintaining all rig equipment, including the drill, he makes sure the motors keep running and the drill keeps turning to the right. Quite a senior role, he is also a roughneck so when he ain't fixing up the motors and hoists, it's his job to latch pipe and move supplies around the rig. Doping pipe and slinging tongs is his secondary role.
Crane operator: (0/1)
The Crane Operator is responsible for the daily operation and maintenance of the cranes, and in addition to this, manages the Floorhands during lifting operations. He /she supervises that all activities are carried out in accordance with the Offshore Installation managers/toolpushers instructions, and delivers essential on the job crew training within lifting and slinging.
Furthermore, the Crane Operator functions as the Helicopter Landing Officer in connection with helicopter operations.
Crane operator: (0/1)
The Crane Operator is responsible for the daily operation and maintenance of the cranes, and in addition to this, manages the Floorhands during lifting operations. He /she supervises that all activities are carried out in accordance with the Offshore Installation managers/toolpushers instructions, and delivers essential on the job crew training within lifting and slinging.
Furthermore, the Crane Operator functions as the Helicopter Landing Officer in connection with helicopter operations.
Medic: (0/1)
The Medic provides medical services to all crew members and is on call 24/7 when on the rig. He/she ensures that the stock of medical and nursing supplies is kept at the required level at all times. If a medical evacuation of a person is required, the medic is responsible for arranging this in cooperation with the OIM.
The Medic is responsible for the organization of preventative healthcare, supervision of physical and mental health of personnel, administration of first aid treatment, supervision of medical emergency preparedness procedures, control of hygienic standard on the rig, and registration of chemicals and medical substances.
[/spoiler]
Here's a video detailing the general duties of a roughneck in a pipe trip.
A nice video demonstrating initial run down procedure, for installing the BOP, whilst it's a drillship and not a rig, It's still worth watching, as the process is largely similar.
A video explaining how connections will be made with a top drive drill, please note there will be a few slight differences on our rig, to this animation.
Worm(Greenhand): (1/2) Matthew Dawn,
The newbie of the oilfield no prior experience, his role is to follow instructions and complete tasks assigned to him, due to his lack of experience he is a safety risk, as he isn't aware of the dangers of the rig, better be good with a brush
Chief Offshore Security Officer: (1/1) PFC.Richtea
The senior officer involved in offshore security, responsible for team deployments, and security on the offshore installation, answers directly to the offshore installation manager, and completes and plans the security risk assessment, as well as equipment assignment.
Offshore Security Officer: (3/3) Nathan.D.Clark, James Dimzy, Burrito Burrito.
Private Contractors, hired to provide security, specialising in maritime security, don't bother them, they won't bother you, they act in the interests of the company, protecting a significant investment, often ex military personnal, these guys are the only people authorised to carry firearms on an board the rig, authorised to prevent potential terrorist threats, or other events that may compromise rig security.
Operations plan
When you commence your tour on the rig, you will be given an induction, and guided tour of the rig facilities, where operations will be explained. The works procedures will be explained to you, as will accident/incident report procedures.

Please note this does not include routine tasks expected of you, such as conducting machinery repairs, doping pipe, maintaining mud levels, and altering the mud density to suit the drilling depth.
Likely Problems we will encounter on rig, explained.
•Well Kick;
The downhole fluid pressures are controlled in modern wells through the balancing of the hydrostatic pressure provided by the mud column. Should the balance of the drilling mud pressure be incorrect (i.e., the mud pressure gradient is less than the formation pore pressure gradient), then formation fluids (oil, natural gas and/or water) can begin to flow into the wellbore and up the annulus (the space between the outside of the drill string and the wall of the open hole or the inside of the casing), and/or inside the drill pipe. This is commonly called a kick. Ideally, mechanical barriers such as blowout preventers (BOPs) can be closed to isolate the well while the hydrostatic balance is regained through circulation of fluids in the well. But if the well is not shut in (common term for the closing of the blow-out preventer), a kick can quickly escalate into a blowout when the formation fluids reach the surface, especially when the influx contains gas that expands rapidly with the reduced pressure as it flows up the wellbore, further decreasing the effective weight of the fluid.
Early warning signs of an impending well kick while drilling are:
Sudden change in drilling rate;
Reduction in drillpipe weight;
Change in pump pressure;
Change in drilling fluid return rate.
Other warning signs during the drilling operation are:
Returning mud "cut" by (i.e., contaminated by) gas, oil or water;
Connection gases, high background gas units, and high bottoms-up gas units detected in the mudlogging unit
Kicks are the primary reason we use a trip tank when tripping out pipe, this is to prevent the fluid pressure changing as we remove the weight of the steel drill string.
•Blowout;
A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed. Modern wells have blowout preventers intended to prevent such an occurrence.
This often catastrophically, launches the drill string out of the wellbore, destroying the derrick, often resulting in natural gas igniting.
•Hydrogen Sulfide leak, H2S
This is where Natural (Sour) Gas travels up the drill string, and leaks onto the rig, there can be many causes, but a common one is insufficient mud weight, or penetration of gas pockets, in this instance we will evacuate the rig, only persons equipped with protective clothing are to remain onboard, the majority of rig power systems must be shutdown, and all sources of ignition removed. The drill brake will be activated, and the mud density drastically increased, until the hydrostatic pressure prevents further gas incursion.
This can often occur simultaenously with a kick.
•Stuck Pipe
Wherein the pipe becomes stuck in the well, unable to turn, or to be safely extracted, this can be due to two seperate factors, either mechanical pipe sticking, or differential pressure pipe sticking.
The latter requires modification of the drilling mud weight density, either increasing it to stabilise a swelling shale or plastic flowing formation (like salt), or decreasing it to protect the depleted zone and avoid differential sticking from the wellbore pressures.
Mechanical sticking can be resolved by back reaming the hole on trip out to clean the hole properly and prevent backfilling.
•Personel disputes
Like every working environment an Oil rig has it's characters, the work shy, the grizzled veterans, the inexperienced, the one man trip machine, the grafters and the screw off's, and boy can these clash, and clash hard, being hard working men, the roughnecks on a rig tend not to take any attitude lightly, and disputes can boil over very quickly, it can be a sexist, brutal, environment, where screw ups can cost hundreds of thousands of dollars, and teeth. Make no mistake working together, will not be easy, and tensions will be high, stuck out on the rig, in the middle of the water........hopefully the crew will still be able to get the job done, if not it could tear itself apart, and in the worst case, someone could loose their life.

We expect applicants to hold relevant experience, and knowledge on the subject matter, to be able to perform and overcome any challenges found in the role.

Extra thanks to;
Bubblegum for putting up with me talking about this event non stop, and complaining when I broke something, and encouraging me to do the event in the first place. And nocolliding stuff with the world so it will work.
Sparx for hosting it, and not setting it on fire.
Khill and Pollux for helping me with the build via suggestions, when things kept breaking.
Anyone who manages to not break the dupe and kill us all get's a bonus medal.
