RISK MANAGEMENT

[Virtual Presenter] When planning a well, it is important to make provisions for kicks, even though they are an uncommon occurrence. The answer for this question is A, True. Being cautious is better than having regrets later. A kick can trigger a dangerous blowout, so safety measures need to be taken. Imagine you are looking for a place to drill on a mountain range; you have to be prepared for possible kicks. A kick can cause a serious blowout, so it is important to have a plan in place beforehand..

[Audio] A Management of Change procedure requires that all team members be cognizant of the established change prior to beginning a project. This is crucial to guarantee that all participants comprehend the task at hand and changes which may happen during its implementation. Prior to drilling a well, it is critical to plan for contingencies, and having the appropriate team members informed of any potential modifications is an integral component of the process..

[Audio] BOPs, or Blow Out Preventers, are a mechanical system designed to act as a barrier between the surface and the wellbore in order to protect against any sudden and unexpected flow of fluids to the surface. BOPs are designed to serve as the first line of defense when it comes to preventing such unexpected events..

[Audio] Well kicks or an influx of fluids during drilling operations can result in significant damage to the well and an uncontrolled release of fluids to the environment. As such, it is important to plan for kicks before drilling a well, as they are uncommon but possible. To ensure proper safety measures are in place at all times during drilling operations, a well control strategy must be adopted which includes the use of a well barrier envelope. A well barrier envelope is a system of physical and operational components designed to form a continuous barrier to prevent the unintentional release of formation fluids. To ensure the integrity of these barriers, they must be tested regularly. The proper care and use of well barrier envelopes is vital to preventing uncontrolled release of formation fluids..

[Audio] To drill a well successfully, it is important to plan for barriers to contain any possible flow of fluids from the wellbore. The barrier envelope must include elements to prevent flow to the environment or to an open formation. This involves using several BOP rams to prevent flow to the environment, as well as wellhead, casing, and cement in the well. The correct answer is A..

[Audio] A well-barrier envelope is a combination of barriers intended to impede the infiltration of formation fluids into the well, into a different formation, or into the atmosphere. Option C is the correct answer, while the other three options do not provide a comprehensive solution to the problem..

[Audio] Answer: According to API Standard RP 53, in case of a well barrier failure while testing, the correct action is to tighten, repair or take any other action, but only after verifying that all pressure has been released and all parties have agreed there is no chance of trapped pressure. Upon completion, the barrier must be pressure tested prior to its use..

[Audio] The correct answer here is d, as you should repair the annular BOP immediately and then retest it. This is an example of the importance of planning for kicks before drilling a well, as the failure of an annular BOP might not be predicted and can cause a hazardous situation. Therefore, it is very important to be prepared for unexpected events..

[Audio] When drilling a well, it is essential to plan for kicks, which although rare, can occur. The test chart must be signed by the pump operator, a drilling contractor representative, and an operator representative. Mechanics, BOP engineers, electricians, and drillers or senior tool pushers are not authorized to sign the test chart..

[Audio] During tripping, it is essential to maintain primary well control. To do this, the hydrostatic pressure exerted by the drilling mud column must remain higher than the formation pressure, the mud pumps must be in good working order, a minimum of one inside blowout preventer (IBOP) must be available on the drill floor, and the level in the active tank must be constant. The correct answer is A..

[Audio] It is imperative to do a check trip and subsequently circulate bottoms-up before drilling a well, in order to guarantee that primary well control has been preserved when removing pipe from the hole. Being aware of this assists in achieving a secure drilling atmosphere. The correct answer is D..

[Audio] Maintaining a drilling mud hydrostatic pressure that is equal to or greater than the formation pressure is primary well control during normal drilling operations in order to prevent a kick and the flow of formation fluid into the wellbore. The correct answer is A..

[Audio] Correct answer is A. A secondary well barrier is an additional object designed to stop fluid from a source from flowing. It is an essential element of well planning, as creating additional barriers is essential to reduce the risk of any unexpected kicks while drilling a well..

[Audio] Kicks can occur unexpectedly during drilling a well and can cause severe damage to both the well and the formation. The correct answers to the questions posed are a, d and e. The potential impacts of a kick can include the inner casing collapsing, the formation below the outer casing shoe fracturing and, in the worst-case scenario, the outer casing bursting. It is essential to plan for kicks before commencing drilling operations, as they can occur rarely but are a real possibility..

[Audio] Proper planning is an essential safety measure when drilling a well. This includes analyzing data to identify any potential hazards and choosing the adequate outer and inner casing according to the geology of the area. Additionally, a drill string should be placed in the well bore and operated with caution. It is also important to study the formation for any anomalies that may cause a kick. Following these procedures will allow for a safe drilling process while avoiding any kicks caused by influx of fluids from the formation..

[Audio] A bad cement job could lead to the inner casing collapsing, the formation below the outer casing shoe fracturing, and the outer casing bursting. These are severe consequences and it is essential to plan for any kicks before drilling a well..

[Audio] We understand the importance of planning for kicks before drilling a well. Kicks are an uncommon but possible occurrence, and thus it is essential to recognize the potential dangers related to drilling and prepare for them properly. We need to determine the pressure and fluid characteristics before drilling to be able to manage a kick effectively. Thank you for your attention..
