Learning  Objective: Recognize drilling  difficulties  and  the development of a water well. 6-68. One method of regaining a loss of  circulation  that  takes  place during  well  drilling  is  to circulate the cuttings away from the drill bit with plenty of water. 1. True 2. False 6-69. Undue wear of the drill pipe is an  indication  of  a  crooked  drill hole. 1. True 2. False 6-70. During a drilling operation, the drill pipe may stick due to which of  the  following  causes? 1. A mud pump of inadequate capacity 2. Allowing the drill pipe to stop and remain stationary in the hole 3. Mud  balling  up  around  the drill  collar  and  bit 4. All of the above 6-71. The drill pipe of your rotary well-drilling rig becomes stuck with  drill  cuttings  that  have accumulated in the hole. How can  you  remedy  the  situation? 1. Pull upward on the pipe with  jacks 2. Circulate  heavy  mud  while trying to turn the pipe 3. Pour oil along the sides of the pipe 4. Pull upward on the pipe and circulate  clear  water  around it 48 6-72. Which of the following is a practical use of a fishing tool? 1. Recovery of a twisted-off drill  pipe 2. Recovery of a wrench that falls into the drill hole 3. Recovery of a drill pipe that falls into the drill hole 4. Each of the above 6-73. The setting of the casing and screens  is  the  first  operation in developing a well after the borehole is drilled. 1. True 2. False 6-74. Gravel packing is placing ungraded aggregate on the outside of the casing to allow for more pro- duction  and  prevent  fines  from entering the well pump. 1. True 2. False 6-75. In completing a developed well, the space between the well wall and casing is cemented to 1. trap  the  drilling  mud below  the  water  table 2. keep  surface  water  or contaminated  water  from seeping  into  the  aquifer 3. prevent  the  drilling  mud from  solidifying 4. All of the above
