Modular well cellar

A method of assembling a modular well cellar system, the method comprising:

• depositing a sealing material on a first side member;
• securing the first side member to a first end member to establish a seal between the first side member and the first end member;
• depositing a sealing material a second side member;
• securing the second side member to the first end member to establish a seal between the second side member and the first end member;
• depositing a sealing material on a top surface of a planar base member;
• and
• securing the first side member, the second side member, and the first end member to the top surface of the planar base member to establish a seal between the planar base member and the first side member, the second side member, and the first end member, wherein the seal between the first side member and the first end member and the seal between the second side member and the first end member is longitudinally offset from a corner of the planar base member.

A modular well cellar system comprising:

• a planar base member for placement below grade in a well cellar excavation and defining an aperture sized to receive a conductor pipe;
• a first end member secured to the base member and configured to support a first lateral wall of the well cellar excavation;
• a first side member secured to the base member, and the first end member, the first side member configured to support a first longitudinal wall of the well cellar excavation;
• and
• a second side member secured to the planar base member and the first end member, the second side member configured to support a second longitudinal wall of the well cellar excavation;
• a seal formed between a top surface of the planar base member and each of the first end member, the first side member, and the second side member;
• third side member secured to the base member and configured to support the first lateral wall of the well cellar excavation, the third side member connecting the first side member to the first end member;
• and
• a fourth side member secured to the base member and configured to support the first lateral wall of the well cellar excavation, the fourth side member connecting the second side member to the first end member.
